A solar pool heater can reduce heating costs significantly. In many climates, solar pool heating is the most cost-effective use of solar energy. As swimming pools are used most when it´s warm and the sun is shining, solar heating is an ideal application.
Solar cell efficiency tells us the amount of solar insolation that is converted into electricity. It usually lies between 12.5 and 15%. In laboratories, scientists are working on solar cell efficiency constantly.
