Photo-voltaic (PV) or solar cells is the best way of harnessing the solar energy. Utilization of solar energy is 100% clean energy and one of the best way of reducing global warming. 41% of electricity is generated by Coal. In India, 59.1% of total electricity is generated by Coal. The energy efficiency of a conventional thermal power station is typically 33% to 48%. So you can imagine the amount of coal consumption in thermal power plants to generate electricity. Generation of electricity by the Thermal process is responsible for many harmful diseases, air pollution, and global warming too. Utilization of solar energy for generation of electricity is one of the best ways to make our Earth clean and green. To save our earth and reduction in the electricity bill, solar cells are best.
If you want to run home's electrical Appliances such as Computer and peripherals, Ceiling Fan, kitchen appliances, Air Conditioner (AC), Television, Home Refrigerator, Motor, Submersible Pump Set, LED Lamps and other electrical Appliances you need to convert DC (Direct Current) into AC (Alternative Current). For conversion of current DC to AC, you can use INVERTER. The capacity of the inverter is measured in term of VA or KVA (watt or Kilowatt) depends on load requirement. But inverters currently consume 4% to 20 % of the converted energy in the conversion process..
Power (P) = Potential difference (V) x Current (I) produced
|At 12-volt battery terminal(Single 150 watts Solar Panel)||At 24-volt battery terminal(Two 150 watts solar panel connected in Series. 2 x 150 = 300 watts)|
|At 12-volt battery terminal(Single 150 watts Solar Panel )||At 24-volt battery terminal(Two 150 watts solar panel connected in Series. 2 x 150 = 300 watts)|
|Note-Current is directly proportional to Intensity of direct sunlight fall on the panel.|
|After conversion, from DC to AC (Efficiency of Inverter from 80% to 96% of the converted Power )|
|From 76.80 watts to 92.16.||From 153 watts to 184.32 watts.|
Conclusion-It is clear that efficiency of solar power after conversion In usable 230 Volt AC is in between 51.20% to 61.44%.
