Solar Energy Conversion

Types

• Helio Thermal Process– Conversion of Solar Energy into Thermal Energy

• Heliochemical Process– Conversion of Solar Energy into Chemical Energy– Solar Energy---Chemical Energy

• Helio Electric Process– Conversion of Solar Energy into Electric Energy

Helio Thermal ProcessThe radiant solar energy falling on the surface placed on the earth is converted directly

into thermal energy

Flat Plate Collector(Non Concentrating Type)

Parabolic Focusing Collector(Concentrating Type)

Flat Plate Collector

Helio Electric ProcessUsing the principle of photovoltaic effect, the solar energy is directly converted into

electrical energy

Solar Radiations

Solar Cell

Helio Chemical ProcessConversion of Solar energy into chemical energy (bio energy) by a process called as

photosynthesis is calledis called as Helio Chemical Process

• Helio chemical process id a photosynthesis process which is the source of all fossil fuels and the food on which we live today.

• Bio mass and bio fuels are examples of Helio Chemical process.
