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.
