Frequently Asked Questions
Basic Issues Related to Renewable Energy
Installation Quality
We only use top-quality materials and certified qualified professionals. Every installation includes official manufacturer warranties and complies with all current regulations.
Innovative Solutions
We implement the most advanced technologies on the market, from smart inverters to real-time monitoring systems, guaranteeing maximum energy efficiency.
Photovoltaic self-consumption consists of producing electricity for your own consumption through solar panels installed in your home or business. They transform sunlight into electricity thanks to the photovoltaic effect, allowing you to cover part or all of the property's energy consumption.
Solar panels capture solar radiation through photovoltaic cells that convert light into direct current electricity. An inverter transforms this current into alternating current compatible with the electrical grid and your home appliances.
The cost of a solar installation depends on several factors, such as system size, roof or ground type, energy consumption, and the technical conditions of the site. As a guideline, for commercial and industrial installations, prices typically range from €850 to €950 per kW installed. For large-scale projects (from 800 kW onwards), pricing can be further adjusted through economies of scale. After a personalized study, we prepare a tailored offer, and we also provide PPA (Power Purchase Agreement) financing solutions, allowing you to enjoy solar energy with no upfront investment and pay only for the electricity generated.
With a photovoltaic self-consumption system, you can achieve savings between 40% and 80% on your electricity bill. The exact savings depend on your consumption, installed power, and energy usage habits.
The complete process includes energy audit, custom design, permit processing, and installation. Physical installation is usually completed in 2-3 days. The permit processing can take between 2-8 weeks depending on the municipality.
Solar panels require very little maintenance. Professional cleaning and inspection 1-2 times a year is recommended. Average annual maintenance cost ranges between $300-850, including cleaning and preventive inspections.
Solar panels are designed to last a minimum of 25-30 years, with performance warranties ensuring at least 80% of their capacity after 25 years. Inverters typically have a lifespan of around 12 years and will likely need to be replaced once.
Yes, municipal permits are required and the installation must comply with current regulations. We handle all the paperwork, including building permits, electrical permits, and administrative registration. Permit costs usually range from $200-1,200.
With self-consumption with surplus, you can feed excess energy into the electrical grid and receive financial compensation on your bill. There's also the option without surplus, with an anti-dump device that prevents injecting energy into the grid.
Yes, solar panels continue generating electricity on cloudy days, although with lower performance (typically between 10-25% of their maximum capacity). Your installation remains connected to the conventional electrical grid to cover demand when solar production is insufficient.
Fully compatible. A photovoltaic self-consumption installation, by definition, always maintains connection to the conventional electrical grid. This ensures continuous supply when panels don't produce enough energy.
Yes, there are different aid programs: tax deductions, regional subsidies, and European Next Generation programs. We advise you on all available aid in your area and help with the application process.
