The solar panels used in our solar water pump systems produce electricity by using the photovoltaic effect. These solar panels absorb the sun’s photons and convert them into energy. This is the main component of a solar water pump system Solar pump systems are important in maximizing pump performance. Controllers can be used to essentially control the water pump. Delta offers a variety of controllers that can help your water pump run more efficiently. Controllers can be used to set a pumping schedule, turn the pump on or off, and help maximize the life of your pump. Innovations in solar pump design now make all kinds of irrigation, Industrial sector and Domestic..
