What to know before installing solar panels

These are the top things to check before getting solar panels on your property in Spain

Installing solar panels on a Spanish property is an increasignly popular way to reduce energy bills and take advantage of the many sunlight hours the country gets.

The Spanish Higher Council of Architects’ Associations stresses the importance of carrying out a study prior to installation to “analyse the fraction of solar radiation that falls on the surface”.

If the roof is sloped and faces south, 100% of the capacity of the panels can be used, but if it faces west, it will begin to receive radiation at midday.

And there are also other elements to ensure that the performance of the photovoltaic installation is optimal.

“Aspects such as the quality of the structure and its installation are very important for the correct performance and durability of the plant and to avoid accidents due to atmospheric phenomena such as wind,” explains Sergio Moreno, business developer manager of Solari Power in Madrid.

It’s also worth remembering that there are also a series of legal requirements for installing solar panels/tiles on homes.

For residential installations, the first requirement is to have a minor building permit from the corresponding local council, and proof that the roof has relevant permission if it’s part of an extension or has been replaced.

In addition, it should also be taken into account that some buildings are subject to protection regulations. “For example, there are buildings that are in protected areas that do not allow the installation or have specific requirements so that they are not observed as a third façade,” adds the expert.
