Pumping and irrigation installations are often large consumers of electrical energy, whether for extraction, lifting, pressure boosting or for pumping water into irrigation systems. In some cases submerged pumps are used and in other cases, surface pumps, although in general they consume much, and high reliability with low maintenance costs is required. The necessary energy can be obtained from the electrical network (installations connected to the network), but in cases where the installation is far from it, autonomous generators are used (isolated installations), usually Diesel. In most cases, demand has a strong seasonal profile, which usually coincides with the months of greatest solar radiation.

The use of this solar radiation by means of photovoltaic panels is an efficient, economic and environmentally responsible solution for irrigation and water pumping applications.

There are different types of irrigation:

When you have a pond where you can store water or the application of irrigation always coincides with the maximum solar radiation and it can be assumed that at some times or days can not be irrigated due to lack of solar resource.

When you want to have energy available all the time and watering does not always coincide with the sun. In this case, regardless of the low solar resource, whether due to bad weather or night time, irrigation can be carried out.

In some cases, because of space, vandalism or to make a previous step to a solar hybridization, it is recommended the installation of gas groups, instead of diesel. These save fuel, are cleaner, quieter and prevent theft.
