DETAILED DESCRIPTION OF THE INVENTION

Multifunctional solar panel S, according to basic variant of performance, derived from housing 15 of transparent material, whose exterior surface in protected by layer of nano-technological material. Housing 15 ( looking in transversal section ) is performed in form of trapezium, with slope of upper base of trapezium made under angle a compared to horizontal line, for draining water from roadway. Upper surface of housing 15 is performed with parallel recesses 151 , for draining water from roadway. Recesses 151 are placed transversally compared to direction of movement of vehicles. Under upper surface, inside housing 15, is placed transparent heating body 10, solar panel 1 and piezoelectrical board 13. All indicated elements are placed one under the other, while under all is placed housing 152 of central directing unit 5 with accompanying electronic and electrical elements. Left and right of panel S, out of housing 15, looking in transversal section, are placed temperature devices 12 electrically connected with central directing unit 5. Out of housing 15, on embankment of highway, are placed external inductor 7a and antenna 16 of sender -receiver which are electrically connected with central directing unit 5. With it are connected and through earth performed also external source 17a of alternating current, drain 18 of direct current into public network, as well as drain 19 of alternating current into public ditrubution network. In face of multifunctional solar panel S, at width of highway, is placed another multifunctional solar panel S with counterslope towards right embankment of highway (looking in transversal section as picture in mirror).

Electrical connections of elements of multifunctional solar panel S are performed in following way ( Figure 4 ). Housing 15 and heating body 10 are connected by electroconductor 20 with circuit breaker 1 1 which is connected by conductor 21 to central directing unit 5, and by conductor 22 with battery 2. Battery 2 is directly connected with external battery 2a. Solar panel 1 and piezoelectric board 13 by conductors 23 are connected with attaching place 14 which is connected by conductor 24 to central directing unit 5 and by conductor 25 to circuit breaker 3. Circuit breaker 3 is connected by conductor 26 to central directing unit 5, by conductor 27 with external exit 18 of direct current, by conductor 28, through current convector 4, with external exit 19 of alternating current. Circuit breaker 3 is connected by conductor 29 to battery 2. Central directing unit 5 is connected by conductor 30 to receiver 9, by conductor 31 to temperature device and by conductor 32 to antenna 16 of receiver-sender. Central directing unit 5 and battery 2 are connected directly with circuit breaker 8 which is linked to current converter 6. Current converter 6 is connected by conductor 30 to inductor 7 and by conductor 31 to external inductor 7a. Central directing unit 5 is connected with circuit breaker 17 which is connected by conductor 32 to external source 17a of alternating current, while by conductor 33 it is connected to conductor 30 and by conductor 34 to conductor 31.

METHODS OF INDUSTRIAL OR OTHER APPLICATION OF THE INVENTION

Multifunctional solar panel S represents a device that enables transformation of solar and mechanical energy into electrical.

Electrical energy charges internal battery 2 or extrenal battery 2a. Batterys serve for maintenance of constant electrical energy. By produced energy are supplied users of multifunctional solar panel S, such as heating body 10, that prevents freezing of driving surface of panel at low temperatures, and housing 15 if it has integrated heaters. To this function also contributes temperature device 12 of external surface of roadway, that is teamed with central directing unit 5. Housing 15 protects mechanically sensitive systems under itself and passes through specter of solar radiation necessary for stiring up solar panel 1. Upper surface (driving layer) of housing is nano-technologically configurated to eliminate dirt, while recess 151 or bump 153, apart from drainage of rain, enables a greater force of friction whith vehicle pneumatics. Apart from this, serious consumers of electrical energy are also inductors 7, 7a that serve for wireless supply of vehicles with electrical energy. Vehicles that pass over or by inductors 7, 7a shall be permitted to consume inducted electrical energy according to instructions from external operational center, by central directing unit 5, according to system of prepayed or postpayed users, as with mobile telephones. Surplus of produced electrical energy is directed to charging batteries or for external direct or alterating network of public distribution of electrical energy. In every case, about distribution and way of use of produced electrical energy„decide" external operational center and central directing unit 5, that are in constant communication and coordination of parameters, by antenna 16 of receiver-sender. In every case, by external operational center and wireless connection with central directing unit 5 is always possible change of regime of work of multifunctional solar panel S. If necessary, for supply of

multifunctional solar panel S one can always use current from public distribution network.
