“Does solar actually work in an Irish winter?” It’s the question we get asked most at this time of year, so here’s the honest answer 👇
Yes, it does. Panels need daylight, not sunshine, so they keep generating on grey days like the ones in these photos. They do produce less in winter because the days are shorter, and most of the year’s power comes from spring to autumn. But the cold doesn’t hurt them at all. Panels actually work more efficiently when it’s cool.
What matters is the total over the full year. And with a home battery (now with a €600 SEAI grant), you can make the most of every bit you generate.
