A solar pump uses power derived from sunlight that is converted into electrical power by Solar Photo Voltaic (SPV) modules,
which give higher power output in the afternoons and lower power output in the early morning and evening. As a result,
solar pump works on varying power input and gives varying water output at a given pump duty head. The most important
parameters to select a solar pump are: how much water is needed daily, at what pump duty head, and at which location. The
location is important because solar energy varies from region to region, and sizing of solar panels depends on the capacity of
solar pumps and also solar radiation of that region.
