Water pumping systems are used for water supply and irrigation. In most cases, these utilize unsustainable energy sources such as fossil fuels.
To reach deep groundwater reserves, diesel generated electricity is used in rural villages to power electric water pumps despite its high maintenance and diesel fuel requirements.
Even though photovoltaic water pumping (PVP) is ready for mainstreaming, its benefits remain largely unknown to communities, governments, and development institutions.
