Photovoltaic solar panels in Madrid: installation and maintenance
Check applicable conditions for the equipment and contracted work: manufacturer, installation and repair do not necessarily have the same coverage. Keep the budget, invoice and documentation, without prejudice to the corresponding legal rights.
To estimate savings, it is necessary to know consumption per hour, orientation, shadows, available surface, installed price and tariff conditions. Estimated production does not automatically equate to bill savings. Compare usage scenarios before deciding, without assuming guaranteed profitability.
The three major installation schemes are: self-consumption with grid injection (the surplus production is fed into the electrical grid and compensated on the bill through the simplified compensation mechanism, up to 100 kW); isolated self-consumption (off-grid, battery-powered, for properties or premises without access to the distribution network); and hybrid systems (connected to the grid but with battery storage to maximize self-consumption and provide backup during outages). At Uniclima, we design the three models and advise on which one best fits your consumption and available investment.
The complete process we carry out includes:
- Consumption and Production Study: we analyse your electricity bills from the last 12 months and calculate the expected production based on the orientation, inclination, and shading of your roof.
- System design: selection of panels (monocrystalline PERC or TOPCon), inverter (string, hybrid, or microinverters) and mounting structure.
- Electrical installation: double-insulated DC wiring, DC and AC protection box, connection to the main panel and earth.
- Processing of the BIE (Electrical Installation Bulletin) before the Community of Madrid and request for the bidirectional metering point to the distributor (Endesa, UFD/Naturgy).
Frequently Asked Questions
How many panels do I need to cover my average consumption in Madrid?
To estimate savings, it is necessary to know consumption per hour, orientation, shadows, available surface, installed price and tariff conditions. Estimated production does not automatically equate to bill savings. Compare usage scenarios before deciding, without assuming guaranteed profitability.
Can I install photovoltaic in a community of property owners?
Yes, and it is becoming increasingly common. The Horizontal Property Law allows the installation of collective self-consumption systems with a simple majority of owners (since the 2021 reform). The system is installed on the common roof, and the energy generated is distributed among the participating neighbors based on participation coefficients. Each household receives the discount directly on their bill. Uniclima designs the system, manages the distribution agreement, and processes the registration of collective self-consumption with the distributor.
How long does it take to amortize a photovoltaic installation in Madrid?
To estimate savings, it is necessary to know consumption per hour, orientation, shadows, available surface, installed price and tariff conditions. Estimated production does not automatically equate to bill savings. Compare usage scenarios before deciding, without assuming guaranteed profitability.
