INDEPENDENT SOLAR SOURCE OF ELECTRIC POWER Russian patent published in 1994 - IPC

FIELD: solar-energy engineering. SUBSTANCE: under condition of the Sun tracking surface of Fresnel lens is directed perpendicular to sun beams. The latter are concentrated into light spot with diameter corresponding to diameter of photocells. Solar radiation detector is end of multifibre optical cable and is located in focus of lens made fast to frame. Multifibre optical cable transfers light spot from focus of lens to surface of photocell (optical losses amount to 0.01-0.05 dB/m) located in plane independent of system of orientation of lenses to the Sun. Such design prevents hitting of contact connection of successively coupled photocells by high-temperature light spot. Joining of end of multifibre optical cable to photocell is performed by means of connection sealing box which excludes effects of ambient factors (moisture, dust and so on) on photocells. Photocells, storage battery and power supply object are housed in bin located in ground which is passive radiator. EFFECT: enhanced efficiency of unattended power supply source. 4 dwg
