It is a heat exchanger that converts the radiant solar energy from the sun into heat energy using the well-known greenhouse etc. It collects, or captures, solar energy and uses that energy to heat water. The solar flat plate collector tends to be more cost effective due to their simple design, low cost, and relatively easier installation compared to other forms of hot water heating systems. Also, solar flat plate collectors are more than capable of delivering the necessary quantity of hot water at the required temperature. Our improved Flat Plate System has proven its effectiveness and durability over the years. These systems can supply hot water continuously for over 300 days per year with zero maintenance and zero cost.
