Solar panel generation in winter.

It doesn t snow every day and most days my solar panels are clean. This is what that looks like.

So winter solar power is not an oxymoron. With shorter daylight hours it does mean generation levels are lower. We all know that solar power uses the suns energy however and during the winter the sun isn t out as much and it isn t as strong so just how much can you expect of your solar pv or solar thermal during those long winter months.

Yet the cons are primarily due to infrequent heavy snows and the shorter days. An average day of solar generation in winter. Of course in the winter the sun rises later and sets earlier so the mornings are dark and the nights drawn in. The efficiency and energy production of solar panels diminish somewhat in winter conditions.
