Understanding Solar Thermal Panels

A large amount of solar energy reflects back into space or is absorbed by Earth’s atmosphere, enough energy to power homes and businesses for years.

The solar thermal panels are used to heat domestic hot water. The panels are filled with antifreeze or evacuated tubes.

A typical thermal-panel system can produce around 70% of a house’s hot water demands. A photovoltaic (PV) system transforms the sun’s energy into direct current (DC) electricity.

An inverter mounted inside the house converts the DC power to standard alternating current (AC), which is then used to power lights, appliances, and other electrical devices. If the PV system produces more electricity than you can use, the excess gets sent back to the power company and you receive a credit on your electric bill.

Solar companies are now offering power purchase agreements to homeowners, which include a free solar system in exchange for government rebates.
