It is important to understand the difference between these two to avoid confusion regarding a solar pool heater and a solar PV.
First of all, the PV in the solar PV system stands for “Photovoltaics,” which means inverting the sunlight into electricity. They do so by using cells. One or two layers of a semiconducting material, commonly silicon, make up a PV cell. The sunlight shines on the cell and produces an electric field that causes electricity to flow through the layers.They are low maintenance and reliable, as they guarantee a warranty of 20 years. Compared to PV solar panels, a pool solar heater takes the cold water from the pool, sends it to a heating tank, and makes it warmer. Even during colder days, you will get the chance to use your pool with solar pool heating systems.
As long as the sun is out, PV will create the required amount of electricity, and a solar heater for a pool will heat the water, while being environmentally friendly and reliable.
