Questions?
We have the answers.

The combination of solar energy with aerothermia is highly recommended. You can power the heat pump with renewable energy generated on your own roof. This considerably reduces the use of electricity from the grid and turns your home into a more efficient and sustainable space.

Our team will evaluate your needs to propose the most appropriate solution. Even so, if you want to get an idea in advance, consider three key aspects: your usual electricity consumption, the available budget and the space on your roof or mounting area. It's also important to decide if you're looking to cover all of your energy demand or just part of it with solar energy.

When you have a solar battery, the extra energy is saved for use when you need it, such as at night or on cloudy days. On the other hand, if you don't have a battery, that excess is automatically discharged to the power grid, which can result in compensation on your bill.

Thanks to current regulations, it is possible to apply excess compensation to another supply in your name, provided that both homes meet the established requirements.
