To calculate the number of solar panels you need to heat your pool, the most important factors are your pool size in square feet of surface area and on which roof you plan to install your solar panels. After selecting a few other factors, we can easily calculate the number of solar panels you will need depending on the solar panel size used. Our methodology is based loosely on the Florida Solar Energy Center’s system sizing method, taking into account our local weather, customer reported satisfaction levels, and years of experience. A properly sized solar pool heating system will result in pool temperatures that can reach around 10ºF higher than unheated pools year-round. Since solar energy is a weather dependent technology, we can’t guarantee a given temperature every time of the year, but the popularity of solar pool heaters indicates that customer satisfaction is extremely high when a proper system design is done.
