Solar Pumping

Solar Pumping

Photovoltaic solar systems associated with a water pump for borehole automate and simplify the process of obtaining water in places where there is no electricity.

Solar pumps can be powered directly by photovoltaic panels, storing water in a tank, or they can use batteries to run whenever needed.


Main Advantages of Pumping Through Solar Energy:

– No use of conventional electricity grid or diesel generator
– Easy installation
– Low level of maintenance
– Long service life of photovoltaic panels: more than 25 years
– Pumping without noise or pollution
– No need for batteries
– The regions of greatest need of water generally have optimal insolation
– The farmer is not subject to an increase in the price of electricity or fuel


Sizing and Cost of the system

A careful analysis should be made comparing the cost of extending the conventional electricity grid to feed a common or diesel-powered pump versus solar pumping. This comparison should take into account not only the initial investment, but also the operating and maintenance costs, as well as the specific characteristics of the site and the well.
In practice, the cost of the ready-to-install solar pump system varies from 1,500 € (for mano-metric heights up to 15 meters and a flow of 200 liters / hour) to more than € 20,000 (for mano-metric heights up to 250 meters and flows up to 250m3 /hour).
