Typically, photovoltaic panels (better known as solar panels) and thermal solar systems are two separate entities. While they both use energy from the sun, solar panels use it to create electricity and thermal solar systems use it to heat water. A common problem with solar panels is that they become less efficient when they get too hot, so this combined system is a perfect match. The photovoltaic solar panels will convert sunlight into electricity while the water will travel through the panels to keep them from overheating. Then the recovered hot water can be used for heating, which will be the main use for this system. Electricity is an additional bonus—and HCC will also save approximately $500 a year.
