Description of Potential Innovation

The solar array shown in Fig 1 comprises a side view of the invention whereas Fig 2 is a view of the bearing and steel shaft connection. The solar array 1 is adjacent to the bearing and steel shaft connection 2 as well as tilt control actuator 3 as shown in fig 3 and fig 4.

The solar arrays 1 can rotate on bearing 5 connected to bearing and steel connection 2 based on the optimal solar tracking controlled by actuator or in an alternative version as a zoomworks related device.

Fig 3 shows the actuators 3 adjusting the solar arrays 1 about noontime. Fig 4 is a similar illustration of the solar tracker later in the day. Fig 5 is an illustration an alternative version using one actuator 3 and a connection of the rows to belt 5.

In Fig 6, hoist 7 can lift and lower solar panels 25 using hinge 8. Retractable window shade 9 or awning would block the wind when solar panel is in the sunset position. In Fig 7 A, garage door opener is shown as an alternative version to the use of a lifting hoist. Reinforcement beams 26 are also shown in fig 6 and fig 7 to keep the solar panel sturdy. However, retractable window like shade 9 in fig 6 and fig 7 and a wall 23 in fig 8 and fig 9 may not make beams 26 necessary as shade 9 and wall 23 can be sufficient to block the wind. An alternative to shade 9 is a retracting platform with a roller 22 that can move when hinge 8 and hinge 21 moves. Fig 10 shows a front view of the solar panels 25 with elongated hinge 8.

An alternative version of In Fig 6, Hoist or lift means with cable means lifts the tracker into optimal solar tracking position. One end of the solar panel is connected to a fixed object with pivot moving means 8 or hinges 8. A retractable awning or shade like means 9 is on the opposite side of the hinge 8 or pivot moving means 8. The purpose of the retractable shade is to prevent uplift of the structure if the wind is strong from that direction. Otherwise the weight of the structure will prevent movement in the high wind as the downward pressure from any direction will keep the structure stabilized. In fig. 10 garage door opener 70 could be used to achieve optimal position for the solar tracker. It could be placed in between two panels located above the panel height in order to control the panel tracking similar to a garage door except that a rod connected to the two support beams with garage door rail supports for structural reinforcement. At the same time, the rod is also connected to a rail like gliding bearing under the solar panels for reinforced connection to the moving rod. The panel rod and support beam connections provide structural enhancement for long term durability. Another garage door like assembly could be placed below the east west pivot version in a perpendicular or 90 degree position from the east west tracker in order to move the solar panels north and south for further enhanced solar tracking similar to a dual axis solar tracker. Garage door apparatus comprises a torsional spring means to reducing the lifting weight of the solar panels. Reinforcement beams 26 are also shown in fig 6 and fig 7 to keep the solar panel sturdy. However, retractable window like shade 9 in fig 6 and fig 7 and a wall 23 in fig 8 and fig 9 may not make beams 26 necessary as shade 9 and wall 23 can be sufficient to block the wind. An alternative to shade 9 is a retracting platform with a roller 22 that can move when hinge 8 and hinge 21 moves. Fig 10 shows a front view of the solar panels 25 with elongated hinge 8.

Additionally, a fence or wall like barrier could be placed surrounding the tracker to avoid wind damage. A clear greenhouse like structure may surround the solar tracking system for avoiding the outside weather and at the same time allow for sunlight to be exposed to the solar cells. The use of a vertical facing double side exposed solar cell could be viable in a greenhouse like environment.

Solar cells on a lightweight platform without the glass in the solar module on a tracker inside a greenhouse is an option to reduce the cost of a heavyweight zomework. In Fig 11, a sawhorse with a pivot is shown that turns the solar cells to face the sun using a zomework. A leverage device like a hoist or garage door opener can be used in order to avoid or reduce substantially the dynamic loading with the pivot reducing the loading. An actuator used normally in solar power tracker can be used to avoid the dynamic loading.

In Fig.101, a long side version of the solar tracker system is shown. A cable and sheave system can reduce dynamic loading with multiple sheaves 301 or wheel like pulley means with the wire rope. Additionally the sheaves and wire set up being the furthest distance from the pivot area of the tracker, the dynamic loading is reduced further. A wire rope 302 is connected to the sheaves to move the solar tracker 303. The actuator 304 moves the wire rope to lower and raise the solar tracker 303. The actuator 304 is near the pivot area controlling the amount of rope to each side of the pivot area. A gearing may be used to increase the rate of travel for the rope. The pulleys or sheaves 301 on lower level base 305 are stationary with the stationary lower level base 305. As more rope is given to one side of the central pivot area, less rope is available to the other side of the pivot area. Therefore one side raises while the other side is lowered.

In Fig. 102, an end or short side version, the cable and sheave system is shown. The actuator 304 would act similar to moving the tracker with moving wire rope 302 in order to correctly position the solar tracker to face the sun. The actuator 304 can be connected to gear or belt system 306 to move the wire rope 302 at longer distances than the movement of the actuator 304. Walls 305 on both sides of the actuator 304 are part of the means to reduce static loading in high wind events. A spring loaded universal joint means 306 can be connected between the wall and actuator 104 with gearing 306 componants. The wind forces on solar panels 303 could pull the wire rope 302 with the spring 306 moving the braked actuator to the wall 305 and hitting electric cut off 308 with one of the sheaves from the gear belt. The sheave is braked or stopped moving when the pulled cable holds the sheave against the wall. The purpose of the side braking means using a spring to allow the actuator to hit the wall and shut off power and at the same time hold or brake the wire in order to reduce dramatically or even eliminate static loading on the actuator 304 in order to avoid the need for several actuators to handle the static loading. The toothed gear belt connected to the sheave would not move and therefore avoid excessive static loading from the high wind on the actuator. The low amount of both dynamic loading and static loading from this pivot, cable and wire solar tracker system would reduce the need for additional or more powerful actuators in a major way and at the same time avoid the damage from the wind , weather elements, and actuator side movement damage which is eliminated with this invention. Fig 103 shows the movement of the belt and actuator area and movement description with the arrows are illustrated with the actuator related components moving sideways in high wind in order stop the electric movement by hitting a stop switch, halting the sheave movement and stopping wire movement of the actuator area components.

In Fig 104 a wheel 310 whereas the circumference is equal the total distance of travel for the wire rope 302 from sunrise to sunset position. The weight 31 Ion the bottom places the wheel in a position where the actuator 304 is at the top as the wind is at a low velocity. In high wind a stopped actuator rotates on the wheel 310 with the wire rope 302 and guided by sheaves 301 moving the wheel 310 in order to avoid static loading on the actuator. A reduction of static loading would allow for less powerful and less actuators and therefore reducing the cost of the solar tracker. When the actuator 304 is not at the top of the wheel, the actuator can be turned off with a cutoff switch 308 or similar means in the detection in the movement of the wheel.

In FIG 707, FIG 708, and FIG 709, the actuator 733, timing pulley 732, and dual direction damper shock absorber 737 is connected in a manner that eliminates or virtually eliminates static loads imposed upon the shock absorber damper and other components of the pulley and belt system. The invention also eliminates or substantially eliminates dynamic loads of the components. FIG 707 and FIG 708 shows the solar panel in full position of sunrise or sunset or a heavy wind condition whereas the panel is leaning on bumper 701. In FIG 707, the solar panel 700 is leaning on bumper 701 in sunrise position or a time of a heavy wind from the west. In 708, the solar panel 700 is leaning on bumper 701 in a sunset position or during a time of heavy wind from the east. Pivot 703 allows the panel to move. In FIG 709, wire rope 720 is connected to belts further connected to a timing pulley (geared) 732. Connection 735 allows the timing pulley to be moved by actuator 733 as the actuator seeks an optimal wind tracker position similar to solar tracking actuators known previously. Connection 736 allows the actuator 733 to be moved by a dual direction damper 737 or shock absorber. The damper 737 in a full extended position would allow the solar panel 700 to lean on buffer 701 illustrated in FIG 707 and FIG 708. The damper retracts to reverse the expansion as the high wind slows down. The support bumper 701 would normally touch the solar panels under sunrise or sunset position under conditions of no or little wind. As a result there would be no static loading on the actuator and wire that moves the solar panel 700. The damper allow for a slow movement of the solar tracker in order to avoid both long term and short term damage. When the solar panel approach the stop bumpers or buffers, the slow speed of the damper controlled solar tracker does not harm anything as the solar panel softly hits the rubber like stop bumpers or buffers 701.

One version of the systems is the placing of a conventional racking system for the panels and fastening it to the pivot point of the wire and pulley system. The use of game change racking is one example.

One version can include further high wind protection with the use of a high wind measuring cup whereas the high wind would turn the solar eye off and simultaneously turn on a solar eye underneath the solar panel with a detection light in the middle near the pivot similar to the sun in a noontime position in China as if Earth is transparent in order to simulate actual noontime conditions for movement of a solar panel 700 into a horizontal position. In FIG 710, solar eye 751 would be turn off while solar eye 752 and light 753 would be turn on in high wind conditions. The eye 752 and light 753 would turn off once horizontal position of solar panel 700 is obtained. When the wind is reduced below the set wind speed trigger point, then the normal solar eye 751 would be turned on and the panel can return to optimal wind conditions. FIG 710 in summary shows the solar panel 700 in a horizontal position during high wind conditions.

10 minute time delay is an option and restart is at lower wind trigger than the trigger at a higher wind speed to level panels.

Advantages include the substantial reduction in the cost of the overall mechanical drive system which is the largest reason for the higher cost of previously known solar tracking systems. Another advantage is the use of this invention being be utilized with solar hot water and solar thermal electric systems. The use of previously known solar trackers for solar thermal electric and solar hot water is either very expensive or cost prohibitive.

In Fig. 105, tracker 321 moves vertical mount two sided solar panel 322 with reflectors 320 using inexpensive material including silver or white colored shrink wrap. The ability for the cable and pulley structure to hold the reflectors in a sturdy manner during high wind in a cost effective manner in another advantage of this invention. A reflector of three times the surface area can increase the power output by 40 percent in addition to the 25% by a total power output increase of nearly 75%. A similar version using a single sided panel would place the solar panel in a horizontal position with the reflectors at a lower angle than the vertical version in order to evenly reflect the solar rays on the area of panel as the tracker moves directly above the sun. Other innovations include the use of I beam like steel items on the footer base area in order to allow a higher quality and lower labor intensive alignment of the tracking mechanical components reducing error situation related to onsite alignment procedures for the individual footings. The tracker unit can be used on a white surface roof. Shock absorbers and bumper protection for the moving panels may be added to insure a slow movement of the panel during high wind events or the unlikely breakage or vandalism of the wire in the tracker support. Additional advantages include the actuator being placed in an area that avoids potential bending problems and allowances for additional weather protection as the actuator can be in an enclosed area under the pivot area.

In fig 12 and fig 13, a side version of similar tracker with a steel shaft connected to the solar module 100 and bearing is illustrated. On sawhorse like structure 103, solar module 100 is connected to steel shaft 107 and is connected to counterweight 101 being slightly heavier than solar module 100. The shaft 107 can turn easily with bearings 104 but with the solar module facing up without the input of the zomework facing the unit to the sun. A wind barrier or wall around the tracking unit would nearly eliminate or limit the influence of wind to move the tracker. Since the sawhorse tracker is an elongated movable structure on a shaft connected by at least two bearings, it is more robust and can withstand wind related damage especially with even the minimal amount of zomework shock absorber and support bumper that already exist. Another sawhorse like assembly could be placed under the east west pivot version in a perpendicular or -90 degree position from the east west tracker in order to move the solar panels north and south for further enhanced solar tracking similar to a dual axis solar tracker.

In FIG 14, a roof top installation is shown with a new way of installing solar units 201 without drilling holes or modifying the shingles and other rooftop protection. The solar panels are connected to a network of piping 202 or beams 202usually steel material which is connected to other pipes or beams extending to the side of the building. In FIG 15, beams 202 and pipes 202, can be further connected to connecting beams and pipes on the side of the building. Several bolts 203or flanges 203 can fasten the elongated beams 202 and pipes202 along the house at several points for further reinforcement. Having a strong roof top rack like structure for the solar panels connected to the side of the building and avoiding impact on roofing material on the building can increase the quality control and speed the construction of the project. With the savings in labor and roofing materials, there can be a reduction in the installation cost of the solar power system. A pipe clamp means can clip or fasten the pipes of pipe like beams to a building roof overhang.

Additional feature include using a platform on the pivot area to hold a racking system suppoting the panels like Ironridge or game change.

In FIG 711, a side view of a wide circular wheel like object is attached to the pivot area of a solar tracker unit. In FIG 712 a front view is shown. On the outer rim 801 is the attachment of the solar panel where the motor, driver or force need to turn the wheel with the solar panel 802 is less than a pivot shaft 803 or axle like object without the wheel as a lever. The radius of the wheel 804 corresponds as force arm in which force is applied. Therefore, a mechanical advantage is applied as a wheel and axle machine similar to a steering wheel or doorknob. The radius of the wheel corresponds to the force arm and the axis of the axle corresponds to the fulcrum. Counterweight 805 is slightly heavier than the solar panel unit as is attached to the opposite side of the wheel or the pivot structure of the solar panel unit as a counterweight to allow for easier movement of the panels with the tracker’s passive mover or active motor.

In FIG 713, the tracker unit could also use a series of pulley systems 806 similar to the one described earlier in this detailed description. The pulley systems 806 described throughout the detailed description could us a block and tackle system for leverage. Other versions may include a series of pulley and wire on one side with a bungee like cord electric rope 807 to allow movement of the tracker toward the pulley system side and its retraction to the other side with the electric rope.

The circular wheel may in one embodiment have support like elongated structures on the side to increase the structural strength and wind load issues of the elevation of the solar panel from the pivot point. The circular wheel may not be needed if the structural support can achieve the same wheel and axle approach without the actual wheel. The wheel may be eliminated or replaced by an elongated structural support in the center near the pivot area. Further wheel and axis lever approaches may be achieve with a large pulley with the actual mover or motor attached to it. At the same time, the circumference of the pulley may also be attached to the outer edges of solar panels. Two large pulleys with the mover or actuator in between attached to a belt is a possible addition to the invention.

Additional innovations include spinoff of shares into a private investment corporation with the goal of being a public entity for the specific purpose of allowing maximum benefit from the technology. At the same time, less stock issuances would be needed to produce and market. The spinoff will be non-dilutive to ( company) user of innovation would receive equity from the investment group in exchange for a limited territory licensing agreement of technology for the use of projects with technology applications. It allows potentially earning lucrative licensing fees. The use of a partnership flip using a public company allows the developer to receive capital gains from the project realized in the present value of future profits instead of waiting for several years to receive profits if the developer was a private company receiving the bulk of the benefits after the partnership flip several years into the future. Other innovations include buying puts and/or writing calls simultaneously in order to hedge against long term electric price fluctuation risk. Upfront capital cost could be reduced or eliminated with our finance innovations using the research and development tax credit and using the reflective roof in conjunction with the accelerated tax depreciation or 30% investment tax credit. The program could be used for the investment of the additional trackers and other methods to increase power output as an additional feature for existing solar projects. Crowdfunding could be used as a means to finance projects. The retrofits could be used to maximize solar renewable energy credits like SRECs in Massachusetts and other states. Nitinol (or other shape memory alloys) as well as means to mimic natural sunflowers could be used to move the trackers to face the sun during the day.

FIG 71.4 illustrates solar tracker platform 902 with solar panels 901 that in which a solar tracking actuator, other active means or passive means pivot 904 to face the panels into the sun. Pivot 903 connected below pivot 904 comprises pivot spring loaded turntable swivel with two parallel arm door closers positioned opposite each other allowing 180 degrees of dampened movement in high wind. Wire or rope connected to the circular edge 906 would be connected to the actuator 908 that moves the panels. In FIG 717, Actuator 908 would be connected to the section connection the top portion of pivot 903 and bottom portion of pivot 904. In an alternative embodiment of this invention, one pivot may be only needed when using a “v belt “ since the “v belt” would be able slip during high wind

FIG 715 comprise a side view of platform in FIG 714. The solar panels would be positioned in an angle in colder climates and not nearly flat as in FIG 715 for tropical climates where the sun is directly above the platform. The comprising use of Mylar sheets 905 for reflection onto the solar panels can be very sturdy and wind resistant unlike the use of reflective panels on other solar trackers. Heat related issues w'ould be resolved too.

In FIG 716, a Yurt 907 (Mongolian circular structure) comprising a small height would surround the circular platform circumference or the back and sides of solar panel areas. A wire, belt or preferably a ‘V-belt " allowing to slip in high wind comprised as the means to move a motor or actuator for the east-west tracker platform to a wind protection position. The solar eye is on a time delay which would allow the platform to move back into optimal position. High w'ind events are rare and the platform may be moving often during those times. However, the damage from the high wind would be prevented. If the solar eye faces north during a protection mode, the platform will be able to correct itself within 24 hours on the next sunny day in a similar means that the solar eye moves to sunrise position from sunset position at sunrise each day. Multiple solar eyes may help with the secondary solar eyes turning off when they reach the sun location. The secondary eyes would only be on when the primary solar eye does not read sunlight. Using a pivot 903 is another option for solar sensors lacking the qualifications to handle the additional high wind load protection means. Another option is having a reverse trip switch when the panels on the east -west platform face west and a stop trip switch when the panel .facing east (or other desired chronological start point) with the clock turning on the motor and . switch relays at 6AM for 15 minutes each morning.

In the finance program, we can convert ordinary income into capital gains whereas the appreciation in the publically traded entity can be used to cash out profits. The operating structure could be profitable. When it is placed into a public company with losses the net taxes would be zero. However, a capital gains would be realized as the public company value would increase with the profits inside the operating structure within the public company. concentrated solar with heat engines to produce electricity. Furling methods could be used to control overheat to move the tracker away from the sun at a temperatures and move it back into desired position after it is cooled to a desired level.

In FIG 719, shows a side view of solar panels 901 with concentrators with preferred Mylar reflective foil or surface 905. The platform 902 rotates using motor and belt 908 on pivot 903 and /or pivot 904. The rotation of the tracker seeks the optimal location for the solar panels 901 using the optimal reflection of surface 905 to achieve the best power output. A window film 909 is placed above the solar panels 901 and reflective surface 905 blocking the infrared rays that do not add power output and letting the visible light reach the panel and reflective area which has useful solar power. In other words, the reflective window film 909 allows high visible light transmission and blocks more than 90 percent of the infrared light rays. In the preferred example each panel and reflective surface receives 70 percent of the visible light and almost none of the infrared rays. As shown in FIG 722, the total surface area of the panel 901 and reflectors 905 is three times the surface area of the solar panel 901. Since the infrared rays which contribute half of the total surface heat and one third of the visible light with related heat is blocked by window film 909, only a third of the heat reaches the total surface area being three times the area of the panels. Therefore, 210 percent of the normal light reaches the solar panel 901 or 70 percent of the total light of the panel and reflective areas being three times the panel 901 surface area eventually reaching the solar panel 901. In other words, the solar panels could produce more than twice the power without over heating the panels. It is known that identical reflectors without the tinted window film 909 can increase the power output of highly heated solar panels when facing the sun by at least 50 percent which is great in itself. However, we can eliminate the dangerous overheating of solar panels. As the solar panels achieving a power output of higher than 50 percent when it is cool since the heat being a factor in reducing output, we can achieve a better than 90 percent power out when using the east- west tracker system shown in FIG 719 and the north-south tracker system shown in FIG 720 and FIG 721. The east- west tracker can increase power output by 25 to 30 percent while the north-south tracker can increase the power output by 15 percent. The reflective surface area 905 with window tint means 909 can add at least 50% to the 140 percent of stationary output. The output would be greater the double the stationary units without the trackers and reflectors.

In FIG 720, a side view of the north-south tracker is shown. Actuator 910 raise and lowers the panel 901 and reflector 905areas on a small platform in order to reach an optimal angle for maximum output from the sun. The north -south actuator is very stable and wind resistant as it is working with a hinged platform comprising the solar panels and reflectors. The actuator is stable unlike other solar trackers which could be vulnerable to the harsh weather. Additionally the length of the platform turned be made parallel to the wind during high wind events. The v belt on the east -west actuator will allow slippage of the larger platform do prevent damage to the north -south actuator and tracker system. Yurt like circular walls at each end of the north - south tracker near the circumference of the larger east-west platform could allow additional high wind protection. Both the invention’s east- west actuator and north -south actuator does not required expensive over engineering unlike traditional east- west actuators and north -south actuators which the traditional tracker are vulnerable to high wind events.

FIG 721 shows a top view of the north-south actuator apparatus. Solar panel 901 and reflectors 905 is fastened to smaller platform 912 which is lowered and raise to reach optimal north -south position for solar output with actuator 910 or more than one actuator 910. The smaller platform 912 is fastened to larger platform 902 with an elongated hinge 911 or row of hinges 911. East west tracker moving belt 906 help bring the platform to an optimal east- west position for power output.

With the two sets of trackers and concentrators, an improved Stirling engine could be used to further reduce the cost of electricity and energy. The improved Stirling engine is less complex with lower cost and the additional benefits of reducing friction and requirements for precision.

In the past, hot engines and Stirling engines were used to generate electricity. Shown in FIG 802, FIG 803, and FIG 804 are pressure chambers containing a small amount of air with one warm end and the other end cool. A displacer moves the air inside back and forth. The technique causes a drive mechanism to move and create energy with the changes in temperature. Additionally, the concentrator shown in FIG 801 can heat the heat engine similar to a solar cooker which works on the principle of concentrating the direct solar rays to temperatures of 250 to much higher than 400 degrees for small focus areas of the concentrator. The concentrator can be constructed with any material including shrink wrap. Using flat panels as reflectors. In FIG 803, a heat engine displacer and piston which is normally a cylinder shape can be a rectangular shape being easier to construct. The displacer and piston can be on a conveyer type roller system to avoid the need for precision and avoiding friction when those parts are moving. In FIG 802, the conveyer belt may be on all four sides in the event of a vertical mount of the piston in order to avoid friction on all four walls of the piston. In FIG 805, a side view is shown with heat fins and a wooden displacer. The heat fins are preferred to be in an east to west direction which is perpendicular to the row of concentrators and focus areas comprising of long black conduits leading to the heat engine. The concentrated heat would travel inside the pipes to the heat engine. FIG 806A and 806B, are rough details of the corner areas of the conveyer belt on each of the four walls of the piston or displacer FIG 807A is a front view and FIG 807B is reinforcement tubes inside the rectangular pistons or displacers. Other innovations include honeycomb facing the wind in the cooling section, black pipe or electrical conduit in the heat section, concrete bricks on rollers for pistons and displacers, roller bearings on the conveyer belt rollers for high rpm, garage door opener mechanism for a shade to control the focus area or pipe heat. The shade could close or tracker move out of the sun when it is highest capacity maybe 400 degrees to partially close it at 375 degrees and reopen when it is 350 degrees. The heat pipes could comprise a flat plate area. Using a parabola, clear plexiglass enclosure could be used to lower the cost by being weatherproof for the parabola and other items. A series of small parabolas could be used with insulated thermal conductors to avoid heat loss between the focus points and heat engines. Additionally, a shallow surface for the working fluid to heat or evaporate quicker could be used. The shallow surface can also evaporate water quicker for water purification.

In the following finance innovations CPACE (Commercial property Assessed Clean Energy) could be used by the public company and/or tax equity investors. items. Solar tracker carport , wheel gear for central pivot, solar tracker with elongated reflected mylar for reflection on to the solar panel covered with heat protection tinted film. The preferred version would allow two to three times greater power output without overheating the solar panels. The use of the tinted film would reflect infrared when placed on the solar panel while the reflectors without film would provide additional solar rays with the tinted film on the solar panels blocking infrared rays (heat) while allowing visible (useful) light to pass into the panels. (2.5 times surface area may allow 1.6 times increase in power output as an example.) Remember use of v-belt (or rope) to allow slip of turntable to backstop (and stop switch) in high wind conditions. The invention may comprise a timer to restore original position on an item after 10 minutes or 6 hours in strong wind as platform hits a switch comprising a photosensor with a time delay to detect the sun location to avoid the motor operating at more than optimal frequent intervals. The use of a motor with a v-belt could be used instead of an actuator. The platform may have laminated plywood and large wheels. Also, a fence around tracker sale 503c and 1399. Fence with the reflected mirror could hide the project in an open area. 70 percent tax credit in empowerment zone and/or use of the 30% tax credit in a charitable donation for a higher return on investment could be added to the finance program. Carports could comprise utility poles and canvas (shrink wrap) enclosures. Marketing for new construction is available in Florida. In addition to the Sterling Engine innovations, a round piston may still be used with a square alignment extension with rollers enclosed in a slightly larger a square outer perimeter as square piston like object in order to prevent mechanical related issues and reduce friction. In FIG 901, Sterling engine cooling section may be in a body of water(lake or pond) or moving body of water like rivers (preferably 50 or 60 bar). A heat sensor could be used to move out of direct sunlight at time intervals to restore to optimal position when overheat. Possible tracker inside PV or albedo (bright reflection) optimization in concentrator. Other innovations may comprise retractable canopies and said hot water containers with one way valves. FIG 903 A is side view and FIG 903 B is a front view of a linear pivot for each row of panels comprising a long linear low cost bearing. FIG 902 shows 9 panels on a platform with each row of three panel with an actuator 1701 to lift and lower panels. In FIG 903 A and FIG 903 B, the height 1702 can be fixed based on latitude or optimal point based on distance from the Earth's equator. Other innovations comprise using the invention adding a low cost solar carport with bamboo poles with plastic or light steel enclosures. Carport housing electric vehicle innovation comprise anti-collision software in FIG 900 and lightweight bamboo frame and/or light steel/plastic enclosure for the need of less batteries. Further carport pole or any tower support cost reductions may comprise helium balloons with bamboo poles or lattice towers with or without material comprising plastic or steel enclosures. Further innovations comprise an extra axle on the outer edge of the wheel as the axle that is connected to the transmission for increased leverage.

BACKGROUND

Prior Art of the invention relate generally to the field of solar energy, and more particularly to the use of using tracking systems to increase the solar power output.

Other methods have been proposed for directing the sun and increasing its effects against a turbine blade or impact impeller. However, the invention can make it cost effective and more durable with the use of many smaller arrays that can track the sun for increased power output.

. Large solar arrays in the past with trackers have a structural stress and fatigue problems in the system that tilts the solar arrays toward the optimal solar production direction. Other innovations include wheels with an extra axle moving the wheel on the perimeter of the wheel connected to the transmission.
