Villena, Alicante, Spain
100% Photovoltaic pumping to an elevated pool
This facility has a PV generator of 360 kWp which enables to pump water from a well of 300m depth to a raised pond with a volume of 175,00m³. From this pond, the General User's Community of Alto Vinalopó distributes the water to the different farms by natural pressure.

Constant-pressure PV pumping system for centre-pivot and sprinkler irrigation
This facility has a PV generator of 160 kWp PV generator and uses an elevated pool to guarantee continuous pressure for both centre-pivot and sprinkler irrigation. The pumping system is installed on a 150 hectares farm devoted to the cultivation of beetroot, which requires about 300,000m³ of water per year.
Uri, Sardinia, Italy
Constant-pressure photovoltaic pumping system for sprinkler irrigation
This pumping system has a 40 kWp photovoltaic generator. The use of automated irrigation systems enables the water needs of a 10-hectare farm devoted to artichoke cultivation to be satisfied. The system consists of three pumps driven by the same photovoltaic generator: two pumps submerged in separate wells, which pump to a pond of 2,000 m³ and a pump to provide pressure to a network of low-pressure sprinklers.

Hybrid photovoltaic/diesel constant-pressure pumping system
This system has a 140 kWp photovoltaic generator. The hydraulic part of the system is hybridised with a diesel unit to complement the PV system and guarantee constant pressure regardless of solar irradiation conditions. The system is installed on a property of 215 hectares devoted to super-intensive olive cultivation. The land is irrigated by means of a drip system and requires around 300,000 m³ of water per annum. During the irrigation season, 80% of the energy used to drive the system was of photovoltaic origin. It is not possible to use 100% photovoltaic energy as the irrigation network requires irrigation periods of 14 hours per day.
