Electricity generation from solar cells and solar thermal power generation
Advertisements
Solution
| Electricity generation from solar cells | Solar thermal power generation | |
| i. | Solar radiation energy is converted directly into electrical energy. | The energy in solar radiation is first converted into thermal energy and then converted to electrical energy through various stages. |
| ii. | The electrical energy is generated directly by the photovoltaic effect. | The electrical energy is generated using reflectors, condenser, cooling tower, turbine and generator. |
