Your House, Your Power, Our Work

The ideal photovoltaic system for your home or business is the one that adapts to your consumption needs and the available surface to install your panels. A specialized technician must design the installation considering aspects such as shading obstacles, orientation, and inclination.   

With our solar calculator, you can simulate what an installation would look like on your property and obtain an initial budget. You can also leave us your details in “Contact“ or below in “WOULD YOU LIKE TO TALK WITH ONE OF OUR SOLAR EXPERTS?” and one of our advisors will contact you to answer all your questions. 

A photovoltaic installation for homes pays for itself in a period of between 4 and 8 years. Several factors influence the payback time. The most important is the relationship between consumption and the size of the installation.   

The amortization period is even shorter if you get the IBI (Real Estate Tax) discounts offered by many municipalities or if you choose an electricity supplier with good self-consumption contracts. It also varies according to our habits. If you adapt your actions to your solar energy generation, your energy consumption becomes more effective. Daily practices have a significant impact over the years.   

The photovoltaic installation components, such as panels and inverters, have reached their lowest price and have been maintained in recent years. Consuming our energy instead of buying it from the traditional utility companies saves you money from the first day. Once you amortize your solar energy system, the panels can produce free energy for your solar panels‘ lifespan.

Yes,  every municipality has specific requirements regarding building permits. In some cases, a simple prior consultation letter is sufficient. Keep in mind that some municipalities request the final Construction Certificate to apply for the IBI discount. In some instances, the installation needs to be approved by the network owner. 

We will take care of all the processing and documentation related to the work permit once we have your authorization. In some districts, the city councils require that the homeowner applies directly, but in those cases, we prepare it, and you only have to submit it. 

We take care of preparing the technical report, plans and define all other details. Once all the documentation has been submitted to the city council, the resolution can take between 1-4 weeks. Once we have the city council’s approval, we will consult you to schedule a date to start installing. 

Systems with batteries are especially suited for areas where the electricity grid does not reach and areas with a high risk of power outages. In these cases, batteries allow the energy produced to be stored and used when necessary. However, battery-free solar installations are profitable by themselves. If you do not have a battery, you can receive compensation for the power you deliver to the grid. In any case, Experta Solar’s installations give you the possibility of integrating batteries. Our experts help you define the optimal solution for you according to your needs and preferences.
