Solar Motor Pump Drive

A solar-powered pump is a pump running on electricity generated by photovoltaics or the heat from collected sunlight. The operation of solar powered pumps is more economical and has less environmental impact than pumps powered by an internal combustion engine (ICE). Solar pumps are useful where grid electricity is unavailable. Solar pump motors may be DC (direct current) and AC (alternating current). Direct current motors are used for small to medium applications up to about 3 kW rating, and are suitable for applications such as garden fountains, landscaping, drinking water for livestock, or small irrigation projects. Since the motor system overall has higher efficiency than an AC pump of similar size, cost is reduced since smaller solar panels are used. Some kind of pump controller is required.
