प्रश्न
Answer in brief.
State the uses of the solar cell.
उत्तर
Uses of solar cells:
- During the day, a solar cell array, which consists of a set of solar cells, is used to power electrical devices as well as recharge batteries that may subsequently be utilised at night.
- Solar cell arrays supply electrical power to satellite equipment as well as isolated locations on the Earth where electric power lines are not available.
- Solar power generation systems on a large scale that are connected to the commercial power grid.
- Radar detectors, monitoring systems, radio relay stations, road lights, and road signs all require their own power supply.
- Consumer electronics such as calculators, clocks, and digital thermometers are examples of indoor uses. (They operate at very low power levels and in low-brightness long-wavelength light from incandescent lights.)
