Municipalities and autonomous communities offer aid to promote the use of renewable energy, and can be requested on the official website of each city council or community, depending on the type of aid you want to access. There are grants that save up to 40% on the cost of the installation and are aimed at neighborhood communities or single-family homes. There is also the option to benefit from significant tax rebates.

Batteries are optional in installations connected to the grid and almost essential in projects isolated from the electrical grid. Self-consumption installations maintain the connection to the network and use it at times when the system is not producing energy, for example at night. Therefore, in these cases, a battery is not needed to store the excess energy.

Although the clouds limit the direct incidence of the sun on the solar panels, they do not prevent the radiation from reaching the photovoltaic cells. The energy absorbed by these cells comes from visible light, but also from other wavelengths that easily pass through clouds. So the answer is yes, the panels can continue to generate energy on cloudy days, as long as there is light in the environment, due to the phenomenon of diffuse radiation. It is also true that it can slightly reduce the performance of the installation, but not so much as to paralyze the supply. On the other hand, it should be noted that in Texas all of our systemsm comes with a 30 year reduction guarantee.

The average useful life of a photovoltaic installation is 30 years, although it can continue to function for much longer. The power will crease very progressively, since the photovoltaic cells degrade little by little. However, with proper care, the module can continue to power a home for up to 40 years.
