Go for Solar thermal solutions, if you use electricity for process heating.
- Solar thermal solutions produce heat directly from Sun, without using electricity.
- Domestic Solar water heaters are the most common examples of Solar thermal systems.
- Solar Water Heating Systems heat water, either directly or by heating a “working fluid” that then heats the water.
Solar water heaters are commonly used to heat water in homes and industries like dairies for can- washing,
heating air, etc. as it is a cost-effective device to heat water for industrial purposes.
- Supplying pre-heated water from Cascaded Solar water heaters to boilers, will reduce energy required to generate steam.
- Concentrating Solar Power (CSP) Systems concentrate the sun’s energy into reflective devices such as
trough or mirror panels to produce heat that is used for industrial processes or to generate electricity.
- Transpired Solar Collectors use solar energy to pre-heat ventilation air.
- Passive Solar Energy Devices use the building itself as both solar collector and storage medium, usually by
increasing the window area on the south side of the building and the amount of thermal mass inside
the building to absorb the solar heat that enters through the windows.
- Day Lighting Systems provide light during the day, significantly reducing the cost of heat gain from electric lighting.
