SOLAR PHOTOVOLTAIC PRINCIPLE |
|
|
|
| Sun light is converted into DC Electricity when it falls on the top surface of the solar cells inside the SPV module by means of direct photovoltaic conversion process. The generated electricity can either be directly used during the sunshine hours or may be stored in storage batteries to be used later. Solar Home Lighting System essentially comprises two solar PV modules/ battery, electronic charge controller, luminaire with built in high frequency inverter, Fan, TV etc. |
