ELECTRICAL, COOLING AND THERMAL ENERGY FOR BUILDINGS

A.l. GENERALLY

The exploitation of solar energy to produce electricity, heat and cooling energy is imperative now in order to avoid climate change.

Solar energy is the only constant and abundant global evenly distributed renewable energy source. So far, the production costs of solar thermal, photovoltaic and solar thermal / cooling applications are still high compared to conventional energy sources. As a result, solar electricity must be supported with subsidized prices for periods up to 20 years (feed-in tarrifs) or tax exemptions (tax credits) and other means of support and solar heating and cooling remain expensive and are still in the research and development stage.

It is therefore necessary to reduce both the investment cost (Capex) of the technology of production of PV modules and the specific cost of the PV modules as well as of the production of solar electricity, heat and air-conditioning so that the solar applications to become competitive and sustainable.

A.2. THE LEVEL OF KNOWLEDGE IN THE FIELD TODAY

The PV technology has achieved a remarkable decline in prices, but still needs even more reduction in both the investment costs of production (Capex) of PV modules and the specific costs of the PV modules and the cost per installed KW, whith parallel potential of exploitation also of the multiple rejected heat, as well as potential of alternative ways of storage than this one of batteries, which is one order of magnitude more expensive and is still in the stage of research and development.

The main obstacle to the use of solar thermal energy mainly for production of cooling energy for air conditioning is the cost of production of hot and superheated water for the operation of absorption heat pumps.

Existing solar collector technologies with vacuum tubes, although massively produced for the production of solar water heaters to 90°C, however, they are one order of magnitude more expensive than the price level that would make competitive the production of solar energy air conditioning.

Also for both technologies for the production of solar cooling and heating energy, remains imperative the need of storage in order to cover the curve of the respective loads also during the night, a field where costs are still too high and is also at the stage of research and development. According to our best knowledge the closest international patent documents to our 3-SUN application for a patent are the following:

P.8. DE202007017351U1 ( KARK AG) 16April 2009 However the above mentioned patent documents although at a first glance present some similarities to our present 3-SUN patent application, they are completely different for the following reasons and namely:

P.l.) US2009056698A1 / JOHNSON ERIC C ET AL. 5/3/2009

1.1a) Paragraphs f 00251, f 00271 and f 00281 drawings 1A-1C and 2A and 2B: The described solar concentrating system in the above mentioned paragraphs of the document P.l. is completely different from the solution of our patent application (in the following also "3-SUNS solution" or "our patent") and namely differs in the following points:

- The reflector structure 107 is composed by a pair of adjacent reflector troughs 120a and 120b, where each of them is bent to form a quarter of a parabola or any other similar concentrating surface in order to reflect the incident sunlight toward a region slightly above a top edge of the opposing reflector panel 106, as shown in the drawings 1A-1C.

- The document P.l. further explains that the reflector troughs 120a and 120b can be produced from plain flat mirrors of small thickness by elastic deformation into a quarter of a parabola or a similar curved surface and by holding them in their final position by the shaping ribs 216 (paragraphs [0027] and [0028] drawings 2A and 2B).

- The entire document P.l. refers to the use exclusively and only of parabolic or quasi parabolic reflectors of a quarter of a parabola, while nowhere in the above document is mentioned the use of plane flat mirrors, except only where it further explains that they are bent by elastic deformation in order to take the shape of a quarter of a parabola and holding them in their final position by the shaping ribs 216 (paragraphs [0027] and [0028] drawings 2A and 2B) and in claim 15, where it claims to protect the above procedure for the creation of quarters of a parabola by elastic deformation of small thickness flat plane mirrors as above.

- And if for a reason, whatsoever, would have been considered that the above document P.l. foresees with some way also the use of plane flat mirrors, even then it isn't possible the creation of a version of the concentration system P.l. with plane flat mirrors for the reasons explained here below in point 1.1.4a:

1.1a. Comparison to 3-SUNS solution:

- 1.1.1a. The "Concentrating Solar System of 3 Suns" is characterized by that it consists of plane flat mirrors as given indicatively in the following patent topics and not only, contrary to the "reflector troughs 120a and 120b each of them is bent to form a quarter of a parabola or any other similar concentrating surface" of Paragraph [0025] drawings 1A-1C, above and namely in our patent is quoted:

"where the System of the 3 Sun Concentration Mirror (A.l.l) (Mirror (A.1.1)) is characterized in that the Mirror (A.l.l) is constructed as a plane mirror" (page 20 line 41 and 42) and further in the next page 21 line 7-14 is given "where the System (A.l) is also characterized in that the flat version of Mirror (A.l.l) can be manufactured by a reflector made indicatively > of polished mirrored stainless steel ... " and shown clearly in the Drawings 1, 2 and 3 of our Patent Application. - 1.1.2a. Parabolic trough mirrors are not appropriate for large scale PV panels made of standard size PV cells of silicon with typical size 156x156mm ¹ , arranged in multiple parallel series strings (1, 2, 3, 4, 5 or 6) as is the case in the standard PV modules manufactured by the PV Industry today. The reason is that parabolic trough mirrors cannot provide a uniform irradiation on large scale solar modules as above, and this is the reason that in paragraph

[0064] below the document P.l. specifies a PV cells size of 78x78mm, because this is the size where they can provide a quasi uniform solar irradiation on the target PV arrays with a width of 78mm and free length of the strings "above the top edge of the opposing reflector panel 106, as shown in the drawings 1A-1C".

- 1.1.3a. In the contrary this is the case and strength of 3-SUN design with flat mirrors, where it can provide a uniform solar irradiation of 3 Suns on the big surface of large scale PV panels made of standard size PV cells of silicon with typical size 156x156mm, arranged in multiple parallel series strings (1, 2, 3, 4, 5 or 6) as is the case in the standard PV modules manufactured by the PV Industry today, where we claim that standard PV modules can be manufactured at practically the same cost but providing 3 times higher nominal power, which means that their specific cost will have been reduced to one third the cost of conventional PV modules of any type, while the Annual Production Capacity of the PV Modules Manufacturing Industry will be multiplied by three, practically without any additional cost or additional investment, except of the requirement to divide the PV cells in three equal parts and connect them in series (in order to reduce nominal current by three so that under three suns it comes again to its nominal size and the internal resistance losses remain the same), which can be accomplished by the existing standard factory equipment without changing the cost of the produced standard PV modules (see page 18 lines 12-20 of our patent application).

See Paper "Experimental evaluation of low concentration collectors for fagade applications"

"http://aut.researchgateway .ac.nz/bitstream/handle/10292/7197/Revised), Pages 3, 4, 6 and 7, Figures 4, 8,9 and 10. - 1.1.4a. And if for a reason, whatsoever, would have been considered that the above document P.l. foresees with some way also the use of plane flat mirrors, something which is not mentioned nowhere in the document and is further not mentioned in the claims, except only where it further explains that they are bent by elastic deformation in order to take the shape of a quarter of a parabola as explained above, even then it isn't possible the creation of a version of the concentration system P.l. with plane flat mirrors for the following reasons:

- With the technical solution of incorporation of flat plane mirrors in the assembly of the reflector structure 107 instead of the αντί reflector troughs 120a and 120b there are created the following problems:

- The arrangement of the PV cells 316 vertical to the plane of incidence of the solar radiation means that they are loosing solar energy of one sun.

- Also the reflection with an angle of 45° from the plane mirrors 106 towards the PV cells 316 reduces the incident direct radiation (let it be 70%) by the cos of 45° (x0,707) multiplied by the reflection efficiency of the reflector 106 (indicatively 0,90), which means that the final incident radiation will be 0,707 x 0,90 - 0,636 or 63,6%.

- This arrangement imposes also to the loss of at least 50% of the difuse radiation, for example for 30% difuse radiation a loss of 15% and consequently a final incident radiation on the PV cells of 0,636 x 0,85 = 0,54 or 54% of one sun.

- In addition if we take into consideration the losses due to imperfect following of the sun (see point 1.2b, page 5, lines 19-36), even if they will reduce the size of the angle of losses, plus the losses due to the cos of the angle of daily incidence, then the total incident radiation arriving on the PV cells goes down to less than half a sun.

- ^" Consequently in case of using plane flat mirrors the total concentration would be less than half a sun, which makes it not rentable and in no case competitive or comparable with the solution of 3-SUNS.

- For these reasons is evident why the above mentioned document P.l. is referring only to parabolic trough mirrors and it doesn't mention at all the solution with flat plane mirrors.

- 1.1.5a. On the other hand 3-SUNS with its flat plane mirrors solution provide to the PV Modules Manufacturing Industry a free of cost triple increase of their Annual Production Capacity, the current Capex of which is estimated to 1,0 Billion USD / GW of production capacity. Today's world annual capacity of PV modules amounts to 120GW/Year and must be doubled each two years (as it was the case the last 12 years) but last 2 years the annual increase instead of 41% as required for doubling each two years, it was reduced below 19% due to very low prices and elimination of incentives in Eu and China, which reduced dramatically the market increase of PV installations, so from 45GW increase in 2014 instead of 90GW as expected in 2016, only 70GW new capacity was installed (see relative study by MIT / NREL Team ² , which asks Tor urgent innovation to reduce by 20% the Capex of the PV Modules Manufacturing Industry as well as by at least 20% the cost of installed PV Parks in order to revive the PV market increase and make once again attractive to the banks the financing of the increase of the Annual Production Capacity of the PV Modules Manufacturing Industry, in order to keep the pace of increase again to 41% annually in order to make possible the target set by the UNO Decision of COP21 in Paris in December 2015 (the world installed PV capacity in 2016 was about 300GW and in 2030 according to COP21 it must amount to more than 10.000GW).

- 1.1.6a. 3-SUN innovation provides both, reducing by 67% the Capex of the PV Modules Manufacturing Industry as well as by 67% the cost of the 3 Sun PV modules, while the mirrors and rest components provide reduced cost so that the level of the relative cost of the installed 3 Sun PV Parks is reduced by approx. 50% compared to the relative cost of installed conventional PV Parks (see page 18 lines 12-25 of our patent application).

- 1.1.7a. This way 3-SUN innovation can help to revive the PV market increase and make once again attractive to the banks the financing of the increase of the Annual Production

Capacity of the PV Modules Manufacturing Industry in order to keep the pace of increase again to 41% annually in order to make possible the target set by the UNO Decision of COP21 in Paris.

1.1b) Paragraphs 100261. ί00901 and [00281, drawings 1A-1F, 10B-10D and 1A:

- According to the above paragraph of document P.l. in order to follow the sun the normal axis 160 in combination with the incident solar rays 135 must create a plane, which must go through the sun (paragraph [0026] drawings 1A-1F).

- But the maximum inclination, which can take the reflector structure 107 or the module 1000 is +/-60 ⁰ total 120° because the post 1018 blocks a greater inclination. This way is effected a partial only following of the sun for 120° instead of a full following of the sun, which requires 180°.

1.1b.) Comparison to 3-SUNS solution:

- 1.1.1b. This means that the solar system of the document P.l. cannot exploit the sun for angles of elevation of 30° in the morning and 30° in the afternoon resulting in a significant loss in the exploitation of solar energy (paragraph [0090] drawings 10B-10D) and more specifically:

- 1.1.2b. For direction East-West of the longitudinal axis 162, (paragraph [0028], drawing 1A) this means that in winter the loss will be 100% for the geographic latitude of Greece and in the summer 25-30%, the other seasons in-between. - For direction of the longitudinal axis 162 North-South, this means a loss of 25-30% all year round.

^' (c ee0l509j) I he capital intensity of photovoitaics manufacturing barrier to scale and opportunity for innovation l.lc) Paragraph [00251 drawings 1A-1C:

- The reflector structure 107 is composed by a pair of adjacent reflector troughs 120a and 120b each of them bent to form a quarter of a parabola or any other similar concentrating surface in order to reflect the incident direct part of sunlight toward a region slightly above a top edge of the opposing reflector panel 106, as shown in the drawings 1A-1C.

l.lc) Comparison to 3-SUNS solution:

- 1.1.1c. The "Concentrating Solar System of 3 Suns" is characterized by that it consists of plane flat mirrors and under laying PV Generators which are utilizing the total of the incident sunlight and namely both the direct and the diffuse part of the incident sunlight, a very important characteristic, which makes them suitable for big cities and industrial areas with a great percentage of diffuse radiation due to industrial emissions, as given indicatively in the following patent topic (see page 18, lines 1-11), contrary to the "reflector troughs 120a and 120b each of them using only the direct part of incident sunlight" as above in Paragraph [0025] drawings 1A-1C, and namely in our above patent topic this is given as follows:

"The technology of this invention of solar production of electricity, cooling and heating energy for buildings, while it does not necessarily require full tracking the Sun to obtain the desired 3 Sun concentration of solar radiation, consisting of 3 Sun concentration PV modules arranged in a suitable position in front of mirrors oriented inclined to the south or SE or SW, able to exploit the entire solar radiation, direct and diffuse one with a concentration ratio of 2.0-3.0 times (or greater) for 6-8 months a year without change of inclination during the winter months and with a reduction of concentration to 1.0-2.0 times during the summer months and by adjusting the inclination angle indicatively every 2-3 months is achieved a reversion to concentration of 2.0-3.0 times also during the summer months, while with continuous tilt adjustment or complete tracking of the Sun, as in this invention, is achieved the maximum concentration all year".

1.2) Paragraphs [00641, [00661 and 100671, drawings 4A-4B:

- The described plurality of PV or solar cells 406 in Paragraph [0064] drawings 4A-4B, is completely different from our patent due to the inability of the parabolic trough reflectors to provide a uniform irradiation on large scale PV panels made of standard size PV cells of monocrystalline or polycrystalline silicon with typical size 156x156mm ³ , arranged in multiple parallel series strings (1, 2, 3, 4, 5 or 6) as is the case in the standard PV modules manufactured by the PV Industry today. The reason is that parabolic trough mirrors cannot provide a uniform irradiation on large scale solar modules as above, and this is the reason that in this paragraph [0064] they specify PV cells size of 78x78mm because this is the size where they can provide a quasi uniform solar irradiation on the target PV arrays with a width of 78mm and free length of the strings "above a top edge of the opposing reflector panel 106, as shown in the drawings 1A-1C" and namely differs from standard PV cells and from the 3-SUNS solution in the following points:

See Paper "Experimental evaluation of low concentration collectors for te^de applications"

"httpv'/aut.researc ^' ngateway .ac.nz/bitstream/handle/10292/7197/Revised), Pages 3, 4, 6 and 7, Figures 4, S,9 and 10. - The solar cell 406 forms the proposed solar cell strings 410, which although small in size (78x78mm) for the reason of non-uniform irradiation by the parabolic trough reflector structure 107 as described above, they are proposed to be specially manufactured so that they can withstand the higher concentration, resulting in higher PV currents and internal resistance losses, for example 5, 6 or 10 times higher PV currents for relative higher concentrations, which will result in 25, 36 or 100 times higher internal resistance losses (losses are equal to l ² .R, that is 5 =25, 6 ² =36 and 10 ² =100 times higher). So the document P.l. practically proposes the construction of special PV cells of high concentration "with increased back surface field strength" or "the top surface conductive grid to be thickened or increased in number to reduce the series resistance" or "the back metallization of the solar cells may be thickened" as it is proposed in the next paragraph [0065], which exposes the weak point of the PV embodiment, which is proposed in the document P.l. and makes obvious the absence of a solution with division of the solar cells 406 in 3 or N equal parts for concentrations of 3 or N suns, as is the 3-SUNS solution. 1.2) Comparison to 3-SUNS solution:

- 1.2.1. Contrary to the above the "Concentrating Solar System of 3 Suns" is characterized by that it provides only a 3 Sun uniform concentration on large scale PV panels made of standard size PV cells of monocrystalline or polycrystalline silicon with typical size 156x156mm, arranged in multiple parallel series strings (1, 2, 3, 4, 5 or 6) as is the case in the standard PV modules manufactured by the PV Industry today, which if left without improvement would impose internal resistance losses (RL) nine times higher than in standard PV modules under one Sun (RL=3 ² .R=9.R). However in our patent is proposed to divide the standard PV cells of monocrystalline or polycrystalline silicon with typical size 156x156mm, in three equal parts each 52x156mm, which are connected in series, so that the overall voltage is tripled (3x0,5V), while the current under one sun is reduced to one third and under three suns is increased again to its nominal value (typical 8-9A), which results in the same internal resistance losses as those in the one sun PV cells (see page 23, lines 1-16 and Drawing No 5).

- 1.2.2. This way our patent permits the manufacture of 3-Sun PV modules same with the standard monocrystaline or polycrystaline or other type PV modules with only difference the division of the PV cells in three equal pieces and their connection in series, which requires no additional investment for the PV Modules Manufacturing Industry while tripling its Annual Production Capacity and reduces to one third the specific cost of the produced PV modules and to one half the cost of the installed turn-key PV Parks facilities as above (see page 18, lines 12-25).

- 1.2.3. Also nowhere in the above mentioned document is mentioned the solution of 3- SUNS, where standard PV cells of Monocrystaline or polycrystaline silicon are divided in 3 or N equal parts and connected in series so that the current under one sun to be divided by 3 or N, so that under concentration of 3 or N suns the current to be increased to its nominal value and the the losses due to internal resistance to remain the same.

- 1.2.4. In the contrary in the paragraphs [0064], [0066] and [0067] and in the drawings 4A- 4B is described the way of interconnection of the special concentrating type solar cells 406 in the solar receivers 400 and their interconnection in strings without division in 3 or N equal parts as above.

1.3) Paragraphs f 00701, f 00731, ί 00741, drawings 4D. 3A. 3B. 3C and 5:

The illustrated in the drawings 4D, 3A, 3B and 3C exemplary solar receiver having a heat sink 416 extending outwardly and coupled to the base plate 408 of the solar receiver 400, is basically different from the 3-SUNS heat sink solution for the following reasons:

- The heat sink 416 as well as heat sink 500 illustrated in FIG. 5 (Paragraph [0073]) are coupled to the base plate 408 of the solar receiver 400 by any known means such as by the use of structural thermal adhesives, bolts, screws, swaging, stacking, welding, soldering, brazing and the like (as given in paragraph [0074]).

- However such a permanent and not flexible connection of the heat sink to the base plate 408 of the solar receiver 400 may introduce structural problems to the PV cells assembly due to different thermal expansion of the two substrates, which might put in danger the integrity of the PV assembly, especially for large scale PV panels. 1.3) Comparison to 3-SUNS solution:

- 1.3.1. Contrary to the above our "Concentrating Solar System of 3 Suns" is characterized by that it provides heat sink solutions, which are suitable for large scale PV panels and to this end they are not firmly connected to the back surface of the 3 Sun PV Generators, but they are independently manufactured by an elastic curved metal sheet, "which are characterized in that each of them consist of a curved Plate (20) made by a thin walled elastic steel sheet or aluminium sheet indicatively 0,2-0,3mm, which with elastic deformation of the outward curve of its structure is caused to be mechanically pressed or alternatively pasted on the back surface of the PV Generators (A.2.1) and holding the final contact position by the Lips (20.2) of the Perimeter Aluminum Profiles (20.1) so that it thus comes into full thermal contact with them for the removal of the dissipated heat from the PV Cells, alternatively with addition to the contact surface between the Plate (20) and the Sheet Tedlar/Aluminum (2.1.c) of a thin semi-fluid layer of a thermally conductive, electrically insulating Material (20.c) facilitating the heat transfer and or slip facility between the Plate (20) and the Sheet Tedlar/Aluminium (2.1.c) for the small differential displacements due to unequal thermal expansion of both these materials, indicatively of a thermally conductive, electrically insulating grease, wherein the Plate (20) bears welded on its external surface the Cooling Fins (2a') made of Aluminum or Steel Foil (2a") with a thin wall, indicatively 0,l-0,2mm, which formulates the parallel Cooling Fins (2a') with a folding of shape Π with direction perpendicular to the longitudinal axis of the PV Generator (A.2.1), with side arms height indicatively triple to the folding width and amplitude fold equal to about 5-10 mm and a width of Π head indicatively equal to one third of the width of fold." (see page 23, line 17 - 35 and Drawings 5 and 6).

- 1.3.2. Where this solution makes perfect contact and heat transfer from the PV cells to the Cooling Fins (2a') or heat transfer fluid tubes, which either dissipate the heat to the environment or transfer it to varius users in order to be consumed, posing no stress due to thermal expansion to the cooperating PV modules.

1.4) Paragraph [0090] - paragraph 100911, drawings 10A-10D:

Module rows illustrated in drawings 10A-10D spaced apart from each other for not shadowing and tracking the sun throughout the day by a single tracking mechanism, although resembling at first glance, they are basically different from the 3-SUNS sun tracking solution for the following reasons:

- The sun tracking model and philosophy of the collector 1000 is that it must be turned toward the sun so that the biscecting plane 105 (drawing 1C) or the biscecting plane 135 (drawing IE) is directed to include the sun in order to secure that the sun rays 135 (drawing IF) are able to focus on the focus areas 104 over tha edges of the adjacent reflector troughs 120a and 120b. However the proposed sun tracking mechanism 1010, 1012, 1014, 1016 allows only a partial coverage of a full day sun tracking, since the tracker linkage 1010 has the most leverage over module 1000 (drawing IOC) and the least leverage over module 1000 (drawing 10D) for a 120° range of motion (instead of the required 180° range of motion for a full day sun tracking), since the collector support post 1018 is blocking further leverage and sun tracking during the early morning and late afternoon hours, thus resulting in losing the relative sun energy related to sun tracking from 120° to 180° (approx. a 20-25% loss).

- In addition during adverse weather like rain storm with strong winds the tracker mechanism is used to orient the collector horizontally minimizing wind loads but with the reflector troughs 120a and 120b facing upwards, in a position which leaves them exposed to sand storms in the desert or hail storms in cold regions, a danger which might destroy the total facility.

1.4) Comparison to 3-SUNS solution: - 1.4.1. Contrary to the above the "Concentrating Solar System of 3 Suns" is characterized by that it provides a sun tracking mechanism under the name "Mirror (A.l.l)" and "Support and Change of Inclination System (A.1.2)", which needs only a limited change of inclination angle in order to provide full sun tracking throughout the day (approx. +/- 30° around the perpendicular to horizontal plane) with no loss of sun energy in the morning or afternoon (see full description of "Mirror (A.l.l)" and "Support and Change of Inclination System (A.1.2)" in pages 21 and 22 and Drawings 1, 2, 3 and 4).

- 1.4.2. Contrary to the facing upwards protection position of the P.l. document, the "Concentrating Solar System of 3 Suns" is further characterized in that it provides the "Overheating Avoidance System (27)" [see page 22 and Drawing 3, System (27)], which consists in the change of inclination of the overlaying Mirror (A.l.l) down to horizontal leveling or accretion on the under laying System (A.2) in order to obscure the PV Cells (2.1) for protection against overheating, hail, dust deposition, protection from snow load or wind load in case of strong winds, with a corresponding activation of the Linear Motor Mechanism (14a), through appropriate sensors and software activation, thus fully protecting the 3 Suns Concentrating Solar System.

2.1) "Page 15, line 10 - line 30, drawings 1, 2"

The solar collector 1 comprising a reflector assembly 3 supporting a reflective surface 5 and an absorber 9 as shown in drawings 1 and 2, although resembling somehow at first glance, they are basically different from 3-SUNS solar collector solution for the following reasons:

- The reflector assembly 3 supporting a reflective surface 5 forms a concave parabolic trough, which concentrates solar radiation 7 on the overlaying absorber 9. This type of solar collector cannot ensure a uniform distribution of the concentrated solar radiation on large surfaces and is rather suitable for concentration PV cells or solar thermal applications, which are less sensitive to non uniform distribution of the solar radiation.

2.1) Comparison to 3-SUNS solution:

- 2.1.1. Contrary to the above the "Concentrating Solar System of 3 Suns" is characterized by that it provides only a 3 Sun uniform concentration on large scale PV panels made of standard size PV cells of monocrystalline or polycrystalline silicon with typical size 156x156mm, arranged in multiple parallel series strings (1, 2, 3, 4, 5 or 6) as is the case in the standard PV modules manufactured by the PV Industry today, which if left without improvement would impose internal resistance losses nine times higher than in standard PV modules under one Sun (3 ² .R=9.R). However in our patent is proposed to divide the standard PV cells of monocrystalline or polycrystalline silicon with typical size 156x156mm, in three equal parts each 52x156mm, which are connected in series, so that the overall voltage is tripled (3x0 _; 5V), while the current under one sun is reduced to one third and under three suns is increased again to its nominal value (typical 8-9A), which results in the same internal resistance losses as those in the one sun PV cells (see page 23, lines 3-16 and Drawing No 5).

2.2) "Page 25, line 22 - page 26, line 16, drawings 8A-8D"

The absorber 201 shown in drawings 8A to 8D comprising the member 203 having a front absorbing surface 205 and a plurality of solar to electrical converters 207, 209 mounted thereon and a plurality of translucent plates or panels 211, 213 positioned above the converters and so on, are completely different from the solution given for the PV cells and assemblies given in our patent for the following reasons given here below:

2.2) Comparison to 3-SUNS solution:

- 2.2.1. The solar to electrical converters 207, 209 mentioned above are subject to a non uniform solar radiation, whose width is changed during the course of the day as shown in drawing 8A (shorter width during morning and evening sun) and in drawing 8B (brighter width extending beyond the borders of the solar converter 207 during solar noon), which shows that there is no provision taken for solar uniformity even over one row of solar cells and of course by no means over large area PV panels as is the case in our patent. The said solar converters 207, 209 can also by no means be conventional standard PV cells of monocrystaiine or poiycrystaiine silicon, as in our patent solution, but rather concentrated type PV cells designed to withstand the adverse conditions imposed by the said design. The same is valid also for the rest of the described embodiment till page 26, line 16.

2.3) "Page 29, line 19 - page 30, line 4, drawing 1"

The mounting system comprising one or more pads 14, the structural sections 10 the upright members 16, the actuator arm 20 and pivotal axis 18 supporting the reflector assembly 3, offers also no protection in case of adverse weather such as hail, snow, strong winds, sand storms and the like. It is therefore completely different from our patent solution for the following additional reasons given here below:

2.3) Comparison to 3-SUNS solution: - 2.3.1. In our patent solution is described the Support and Change of Inclination System (A.1.2), which is characterized in that it comprises the Rear Push-Pull Beam (11), the Push- Pu!S Arm (13), the Counterweight (13a), the Hinges (10a) and (10a'), the Arms of Parallel Inclination (lOd), the Supports (13b) and the Coupling Beam (14), which supports the Mirror (A.l.l) and the Mirror (A.l.la), all made indicatively of aluminum profiles or hollow steel profiles and the Linear Motor Mechanism (14a), which through the Electric Switchbox (15) and suitable Sun Tracking System (16), gives movement and driving for tilting the Mirror (A.l.l) and the Mirror (A.l.la) (see pages21, line 43 - page 22, line 8 and page 22, line 31 - line 36 and shown in Drawings 1, 2, 3 and 4).

- 2.3.2. Where in addition the Support and Change of Inclination System (A.1.2), is further characterized in that it creates the Overheating Avoidance System (27) which consists in the change of inclination by the Support and Change of Inclination System (A.1.2) of the overlaying Mirror (A.l.l) down to horizontal leveling or accretion on the underlaying System (A.2) in order to obscure the PV Cells (2.1) for protection against overheating, hail, dust deposition, protection from snow load or wind load in case of strong winds, with a corresponding activation of the Linear Motor Mechanism (14a), through appropriate sensors and software activation, as described in pages 21, line 43 - page 22, line 8 and page 22, line 31 - line 36 and shown in Drawings 1, 2, 3 and 4.

2.4) "Page 15. line 10 - line 30, drawings 1. 2"

The solar collector 1 comprising a reflector assembly 3 supporting a reflective surface 5 and an absorber 9 as shown in Figures 1 and 2, although resembling somehow at first glance, they are basically different from our patent solar collector solution for an additional serious reason as follows:

- The reflector assembly 3 supporting a reflective surface 5 forms a concave parabolic trough, which concentrates so!ar radiation 7 on the overlaying absorber 9. This type of solar collector can reflect also only the direct part of the incident sunlight toward the overlaying absorber 9, as shown in in Figures 1 and 2.

2.4) Comparison to 3-SUNS solution: - 2.4.1. Contrary to the above the "Concentrating Solar System of 3 Suns" is characterized by that it consists of plane flat mirrors and under laying PV generators which are utilizing the total of the incident sunlight and namely both the direct and the diffuse part of the incident sunlight, as given above in Paragraph (1.1c) and (1.1.1c) and in the given therein relative topic of our patent (in. page 2, lines 1-11), contrary to the "reflector assembly 3 supporting a reflective surface 5 forming a concave parabolic trough, which concentrates solar radiation 7 on the overlaying absorber 9", which use only the direct part of incident sunlight.

3.1) "paragraph [00291 - paragraph [00301. FIG. 2"

The above paragraphs describe the solar assembly 10 comprised of a flat plate panel 12 comprised of a solar cell layer 14 and a backing structural support layer 16, forming the surface 18 with a standard tilt to the south, corresponding to the description of prior art solar PV panels and the losses they suffer during the morning and the afternoon hours due to acute angles of the rays striking the surface 18 and deflected away from layer 14 without conversion to electricity.

3.1) Comparison to 3-SUNS solution:

- 3.1.1. In our patent solution the first reflection of the solar rays with acute angle happens on the overlaying Mirror (A.1.1) where total reflection is an advantage bringing the whole of the rays striking Mirror (A.1.1) on the underlaying PV Cells (A.2.1) which are placed in a vertical position to Mirror (A.1.1), thus intercepting the solar rays at much greater angles (see Drawing 2, 3, 4 and 9). In addition both the under laying PV Cells (A.2.1) as well as the Front Glass Cover (2.5), (A.2.5) and (2.1d) are constructed with antireflection coatings, as it is the state of the art in PV Cells, PV Panels and solar collectors front glass covers (see also Drawing 5 and 6), reducing dramatically the reflection losses.

3.2) "paragraph Γ00331, FIG. 2"

The serpentine-shaped metal tube 20 described in the above mentioned paragraph seems to be welded or otherwise firmly attached to layer 19 and this one to layers 16 and 14 thus posing serious stress to the so!ar cells layer 14 due to different expansion of each layer and this danger has prevented the exploitation of the dissipated heat from the solar cells in the conventional PV panels. Our patent solution is different, solving this problem, as described below:

3.2) Comparison to our solution:

- 3.2.1. In our patent solution the Heat Dissipate Surfaces (A.2.2) have been very carefully designed and foreseen to be independently manufactured by an elastic curved metal sheet, as described above in paragraph 1.3.1. and in our patent text (see page 23, line 17 - 35 and Drawings 5 and 6). 3.3) "paragraph Γ00381, FIG. 5"

The solar assembly 50 of FIG. 5 comprising the rectangular frame 52, the axle receptor 56 and the series of solar cell assemblies 10 and/or 40 is not suitable to be positioned for accepting solar rays in angles other than the perpendicular to the impingement face 18, due to the need to utilize the side reflectors and to avoid shading of the solar cells by the members 52, 70 and 72, which shading would jeopardize the output of the solar arrays 10 and/or 40. It needs therefore full tracking and not only one axis tracking as given in paragraph [0038] and FIG.5.

3.3) Comparison to our solution: - 3.3.1. In our patent solution all members of the Support and Change of Inclination System (A.1.2) are kept behind the Mirror (A.l.l) and the PV Generates (A.2.1) in order to avoid shading and fascilitate system integrity and ease of fabrication, (see pages 21, line 43 - page 22, line 8 and page 22, line 31 - line 36 and Drawings 1, 2, 3 and 4).

3.4) "paragraph 100401- paragraph [00421, FIG. 5" The flat panel of assemblies 10 and 40 of FIG. 5 comprising deflection frames 62, diagonal support frames 70 and 72, cross members 68, the rectangular frame 52, the axle receptor 56 as mentioned above must be utilized only for accepting solar rays in angles perpendicular to the impingement face 18, due to the need to utilize the side reflectors and to avoid shading of the solar cells by the members 52, 70 and 72, which shading would jeopardize the output of the solar arrays 10 and/or 40. It needs therefore full tracking, which adds cost and complexity and not only one axis tracking as given in paragraph [0040] - [0042] and FIG.5 resulting in increase of the system complexity and cost.

3.4) Comparison to 3-SUNS solution:

- 3.4.1. As already mentioned above for paragraph [0038], FIG. 5, in our patent solution all members of the Support and Change of Inclination System (A.1.2) are kept behind the Mirror (A.l.l) and the PV Generates (A.2.1) in order to avoid shading and facilitate system integrity and ease of fabrication and opposite to the document P.3. they don't need 2-axis tracking (see pages 21, line 43 - page 22, line 8 and page 6, line 31 - line 36 and Drawings 1, 2, 3 and 4).

- 3.4.2. In addition due to the fact that the PV cells of the solar arrays 10 and / or 40 remain total, without the beneficial solution of division into 3 equal parts and thereafter connection in series, as is the solution given in our patent. For this reason the losses due to the internal resistance for a concentration factor around 3, (where the current is increased by 3), they are increased by 9 (because they are equal with l ² xR and are increased with the square of the current), with consequence that on the one hand their efficiency is reduced relatively and on the other hand its PV cells are subject to great stress, with reduction of their life time and danger of destruction.

B. ADVANTAGES OF THIS INVENTION

The main advantages of the present invention of 3 Sun for the production of solar electricity, cooling and heating energy for buildings are the following:

- The technology of this invention of solar production of electricity, cooling and heating energy for buildings, while it does not necessarily require full tracking the Sun to obtain the desired 3 Sun concentration of solar radiation, consisting of 3 Sun concentration PV modules arranged in a suitable position in front of mirrors oriented inclined to the south or SE or SW, able to exploit the entire solar radiation, direct and diffuse one with a concentration ratio of 2.0-3.0 times (or greater) for 6-8 months a year without change of inclination during the winter months and with a reduction of concentration to 1.0-2.0 times during the summer months and by adjusting the inclination angle indicatively every 2-3 months is achieved a reversion to concentration of 2.0-3.0 times also during the summer months, while with continuous tilt adjustment or complete tracking of the Sun, as in this invention, is achieved the maximum concentration all year. - Because the PV modules (generators) with the innovation of the present invention operate under a three suns concentration with the same electrical losses and the same operating temperatures as the conventional ones and they produce for the same nominal capacity the triple electricity at one third of the specific cost of the corresponding conventional photovoltaic modules, they allow to the existing production facilities of PV modules to triple their production of an equivalent nominal PV modules capacity, without any need for additional production investment (no additional Capex) or any additional production costs, while they can sell their production more than twice cheaper per nominal KW equivalent PV capacity with an increased and sustainable profit margin.

- Also the cooperation with simple flat mirrors and a simple mounting system that can be satisfied with a seasonal only tilt change to track the sun, give a lower cost per installed kilowatt and kilowatt-hour produced compared to the current state of the art, while in parallel it enables protection against overheating, hail, dust accretion, protection from snow load or wind pressure load in case of strong winds, thus reducing the risks of weather.

- The present invention allows the production of electricity, cooling and heat energy from the 3 Suns Concentration PV generators by exploiting the otherwise wasted heat of the PV cells to produce cooling energy for buildings air-conditioning, thus displacing a multiple of utility reserve capacity aiming to address the peak load due to air-conditioning in the summer for the benefit of Electric Utilities, so it can be an effective and low-cost weapon in the battle against climate change, given that the energy consumed in buildings, eg from the EU represents 40% of its annual energy needs.
