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 mornings and evenings. E.g. a standard 5 HP pump working on grid power diesel engine for, say 2.5 hours a day, may give the same water output in a day as a solar pump of 3 HP working for 8 hours using sunlight. This is an important fact to keep in mind for appropriate solar pump selection and application engineering. The most important parameters to select a solar pump are: how much daily water is needed, at what pump 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 solar energy of a region
