Solar to generate electric (solar panels) and solar to heat pools are totally different systems. The solar pool heater is in effect a water pipe and bag system that lays on the roof and water moves across the roof to absorb the heat from the sun. The system is black since black absorbs most of the sun's rays. There is no electrical generation with solar pool heater and no electrical storage. As the pool water is pumped and filtered, the water is heated on the roof and pumped back into the pool.
