Nowadays, the use of photovoltaic solar energy to supply with electricity those irrigation installations where no electrical grid exists or where the electricity is generated through generators is the most reliable solution and the most economically feasible.
These systems work as any other off grid photovoltaic installation. They generate electricity through photovoltaic solar panels. This electricity can be immediately consumed, if necessary. Conversely, it is stored in batteries to be recovered when demanded by the pumping and control systems. A proper dimensioning and execution of the installation allows us having the same level of flexibility in the programming and a level of security of supply higher than that provided by the electrical grid in a clean, secure and totally renewable way.
In the case of consumption supplied with generators, the off grid photovoltaic installations allow us to totally or partially replace the consumption of diesel oil and the tedious tasks of deposit filling, maintenance costs and noises due to the functioning.
These systems, differently from the systems connected to variable drives, offer us a more flexible and secure operation but require a higher investment.
