Is It Profitable To Put Solar Panels In Galicia With Tiempo Inestable

The high price of electricity has led many to value the idea of ​​starting with electricity self-consumption with the installation of photovoltaic panels. However, it can be a reluctant idea if you live in regions of Spain where the weather is more unstable than in the south or the Mediterranean coast.

The energy company Peusa categorically explains that photovoltaic panels continue to generate energy on days with adverse weather conditions. However, they do so between 10 and 25% of their usual performance. An amount varies depending on two factors: the technology of the panels and the thickness of the clouds.

Regarding the cloud level, the photovoltaic panels continue to work approximately 60% of their total capacity on days where the cloudy sky is not very thick. It should be remembered that the panels do not feed on heat, but on light. On much more adverse days, such as rainy days, Peusa explains that they can also be useful because they help eliminate dust, sand or dirt accumulated on the surface of the panels.

Beyond the weather conditions, the most important factor to take into account when installing a photovoltaic self-consumption system in a region with unstable weather is the quality of the solar panels . Peusa explains that these types of systems are increasingly efficient, which is the key to take into account if a plate system is to be installed in areas with fewer sunny days.

The company explains that the performance or efficiency of a solar panel describes what percentage of the sunlight that hits it is actually converted into electricity. Logically, the higher this percentage, the greater the amount of electricity generated by the hob (expressed in kWh) and, therefore, the higher its performance, which is what ultimately interests us in terms of saving on the electricity bill. the light.

Taking this into account, solar panels are considered very efficient from 19%. Currently, most manufacturers offer percentages between 15% and 22% in the best cases. Likewise, the efficiency record in the conversion of solar energy into electricity is set at around 24%.
