Solar panel batteries are devices that allow you to store the energy your panels generate but that you don’t use right away. By adding a battery to your system, you can have access to electricity even at night or during particularly unfavorable weather conditions.

The number of solar panels you need mainly depends on two factors: the available space for installation, whether on the roof or on the ground, and the electricity consumption of your home or business. Other factors that also play a role include the type of inverters, shading, mounting structures, and the orientation of the panels.

The price of a solar panel is around €220 per unit. Considering that an average Spanish household needs about 10 solar panels to cover its energy consumption, the total cost of a photovoltaic installation amounts to an average of €4,500, including equipment and labor.

The answer is yes, always. On average, a SotySolar customer takes between 5 and 7 years to recover the investment. It is possible to achieve savings of up to 60% on the electricity bill.
