According to Mr. Robichaud, this system is very efficient as it does not take much sunlight to power it since, in addition to sunlight, it also use UV rays to heat the water on the roof.
That water contains non-toxic antifreeze that produces a chemical reaction when it comes in contact with heat, which then circulates through the system. This process serves to power a very large hot water tank. Mr. Robichaud is even thinking about installing hot-water radiators or baseboard heaters to heat part of his house. Very efficient system that is ideal for heating a pool. All controls are electronic.
