The photovoltaic effect produces a flow of electrons. Electrons are excited by particles of light and find the attached electrical circuit the easiest path to travel from one side of the solar cell to the other. This excitation of electrons causes an electron flow. The solar cell takes these electrons and directs them to flow in a path or an electrical circuit. Photovoltaics is the process of solar electric cells converting sunlight directly into DC power. This DC power is then used to run a pump.
We generally recommend that a solar pump controller be used in between the Solar Panel and Solar Pump. There are several advantages to using a controller. in most cases the controller will come with some kind of float switch connection which will allow the pump to be shut off when the tank or cistern is full thus avoiding overflowing of water and potential waste. The second reason is the controller provides protection to the pump by only allowing the pump to start when there is sufficient power available, this avoids the pump from stalling in the morning as the sun rises.
