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.
