Are Solar Panels Efficient In Winter

Yet the cons are primarily due to infrequent heavy snows and the shorter days.

Are solar panels efficient in winter.

It doesn t snow every day and most days my solar panels are clean. Like most electronics solar panels function more efficiently in cold conditions than in hot. Since the days are a bit shorter you won t produce energy for as long as you would during long summer days. If every day was like this i d get 120 kwh for the month which is pretty exactly what my 5 year average was.

The sun rises at 8 am and sets at 4 pm. This is what that looks like. Here in buffalo an average day in winter is just grey. On the other hand the efficiency and energy production of solar panels is typically enhanced by cold temperatures.

The efficiency and energy production of solar panels diminish somewhat in winter conditions. As long as there is light your system will convert it into clean energy. This means that your panels will produce more power for each precious hour of sunshine during the short days of winter. Winter months are actually good for solar energy production as long as your panels aren t covered by snow.

However the impact temperature has on solar panels mainly depends on the voltage of your units. Don t rely on your panels in winter to heat your hot water or run your electric heating but remember that the savings over the whole year should pay for the system in less than 10 years.
