Solar pump definition is, as the name suggests the pump uses solar energy to function. Solar pumps are robust, installation is simple, minimum maintenance is necessary, and very expensive when we compare them with normal water pumps. The life span of these pumps is a maximum of 20 years. But from time to time the solar panels need to be cleaned for running. These kinds of pumps are mainly used where there is an electricity problem otherwise consistent power supply is not accessible. Solar Pump Block Diagram The solar pump block diagram mainly includes a solar panel, water pump, electric motor, and controller. This pump is basically an electrical pump, and this pump uses the electricity which is received from the solar panels to work. These panels store the energy from the solar. The electric motor manages the alternating current or direct current. The controller used in this system adjusts the output power as well as speed.
