Solar Thermal Technology harnesses the solar energy for heat. This is a simple and very cost effective technology that provides a renewable option for heating. The technology is primarily used for Water Heating and Space Heating and can also be used for cooking and other heating applications.
Solar Water Heating
Solar water heating units have three key components, solar radiation collector, the heat transport liquid and the heat exchanger. The system uses the radiation collected from the sun by the collector to heat the heat transport liquid which in turn heats water through heat exchanger. This pre-heated water, depending on the efficiency of the system and temperature of the water, could be used as is or as input to the main gas or electric water heating system. In cold climates like Canada, using solar water heating system for pre-heating the water can reduce the expense and usage of gas or electricity by more than 70%.
Solar Space Heating
The other main area of Solar Thermal Products that SolarGrid Energy focuses on is the Solar Space Heating. This technology works on a similar concept as that in solar water heating with the only difference that in this case, instead of water air is heated or pre-heated before it enters the furnace and HVAC system of the buildings intended to be heated. This helps reduce the cost of space heating by up to 50% as the space heating system preheats the air (20 degrees Celsius or more compared to fresh outside air).
SolarGrid Energy intends to try its own design based on the solar water heating systems for Solar Space heating and manufacturer it to provide these services to its customers. The advantage of SolarGrid Energy’s unique design for space heating system is that it is simple and can easily be integrated into solar water heating system to provide an integrated option to customers.
