How does a self-consumption installation work?
They generate direct current thanks to the sun, then an inverter converts it into alternating current and automatically injects it into the internal grid to supply us. The unused energy (surpluses) is directly fed back to the grid and you receive compensation for it, or it is stored in batteries. The photovoltaic self-consumption installation works automatically. You don’t have to worry about turning it on or off. As long as the sun is shining you will keep saving on your bill.
Is a self-consumption installation profitable?
YES, ALWAYS. The drop in the cost of photovoltaic modules in recent years has meant that the price of self-consumption installations has been significantly reduced. Added to that, the Royal Decree 244/2019 (in addition to removing the “sun tax”) introduced a rule obliging companies to compensate you for the energy you don’t use and export to the grid. A photovoltaic installation optimised for consumption can be amortised in the first years of its life.
Do I need any permit to have my own self-consumption installation?
The necessary permits for a photovoltaic self-consumption installation vary depending on the power and modality chosen. A prior inquiry must be carried out in case there are urban planning restrictions. If the installation is possible, an works licence must be requested from the Town Hall. In some cases, only a Responsible Declaration is required. In all cases Uninergia will handle any necessary administrative procedures.En todos los casos UNINERGIA se encargara de cualquier trámite administrativo necesario.
What is the optimal size of my self-consumption installation?
It depends on several factors — consult us and our technical team will assess your home and daily consumption to tailor it 100% to your needs.
How can I pay for my self-consumption installation?
At Uninergia we offer you several financing options, so that you can enjoy your self-consumption installation and pay gradually with the savings from your electricity bill.
What maintenance does a self-consumption installation have?
Practically none — you may clean the panels if you see they are a bit dirty after a few years, although it is not strictly necessary. Besides that, you only have to wait for the sun to come out to start saving.
How can I know if my installation is correct?
The production of the installation will be monitored in an easily accessible app, allowing you at any time to check in real time how much it is generating and if there is any problem. In the event of a fault, you can call us and we will take care of the solution.
What is the useful life of a photovoltaic system?
Because they have no moving parts and work with the best materials, our equipment can last more than 25 years: the first ten producing at minimum 90% and at 80% the rest of its useful life.
