Do solar panels work during winter?

We use to think that photovoltaic solar panels only work in summer, when the temperature is higher and we have more hours of sunlight. However, this is not true because solar panels still produce energy in winter.

In recent years we have seen a spectacular increase in solar photovoltaic self-consumption installations. Increasing public awareness of the climate issue coupled with rising electricity prices have been the main causes. In addition, these projects are functional almost anywhere and at any time as solar panels in winter continue to generate large savings.

This question raises important doubts among users when deciding whether to start a PV project. Generally, there is considerable ignorance about the true performance of the panels and how they can be used to generate savings on the electricity bill. Therefore, in this article we will address some of the questions that may arise about the efficiency of solar panels in winter.

First of all, let’s make an effort to refute the myth that solar energy is only for summer. Contradictory as it may seem, the sun still radiates light in winter with a similar intensity. And solar panels work because of the light, not because of the temperature. Therefore, the panels do continue to generate energy in winter despite having fewer daylight hours. In fact, with the same amount of light, the panels work better the lower the temperature.

However, is it worthwhile to install a self-consumption system in winter? We must bear in mind that the decision to implement a photovoltaic solar energy project is a long-term issue. Currently it takes around 5 years to amortize the installation of solar panels. And considering that you will start noticing the savings from the first day on your bill, then any time is a good time to start.

Of course, we recommend that you choose solar modules that offer higher efficiency so that you can get even more out of them at this time of the year. You should keep in mind, however, that you will have to maintain your panels, especially in winter so that they are not damaged by adverse conditions or meteorological phenomena such as heavy snowfall.

Batteries, on the other hand, can also be affected by low temperatures. Here it will be essential to find a suitable place for their placement, but beyond that you can be sure.

So, long story short, solar panels are a good alternative even for the winter. And you can start enjoying them from the very moment of installation. What are you waiting for? Put yourself in the hands of the best professionals and start planning your winter solar panel installation today.
