FAQ

The most common questions

How many panels do I need for my home and what's my payback (ROI)?

It depends on your consumption, your roof area and orientation, and your goals. As a reference, a family home typically installs between 3 and 8 kWp. We always run a free diagnosis before any proposal, with a clear estimate of production, monthly savings and payback period — typically 6 to 8 years in residential.

Does my system work if there's a grid outage?

Only if you have a battery with a backup function. A plain self-consumption system shuts down during a grid outage, for safety reasons. With storage and the right configuration, your home keeps essential circuits running.

How long do batteries and panels last, and what maintenance do they need?

Panels last 25 to 30 years, with a production warranty; lithium batteries typically last 10 to 15 years. Maintenance is minimal — we offer Operation & Maintenance contracts for those who prefer to delegate it.

Can I charge my electric car with solar energy?

Yes. We integrate EV charging with your solar system, prioritising the energy you produce. Charging can be scheduled for peak solar production hours.

How does weather affect panel production?

Panels produce every day, though less on cloudy days or in winter. The system is sized for your annual consumption, balancing summer surplus against lower-production months.
