Do Solar Panels Work In The Winter?
A common myth is that solar panels do not work during winter, but in contrary, the cold temperatures will typically improve solar panel output. The most powerful energy resource available in the world is right above your head. Even in the most frigid weather, solar panels turn sunlight into electricity.
The white snow can also reflect light and help improve PV performance. Winter will only hurt solar production if the panels are covered with snow. Solar panels create energy from our sun’s abundant light—not the sun’s heat. The efficiency and energy production of solar panels diminish somewhat in winter conditions.
The cons are primarily due to infrequent heavy snows and the shorter days. On the other hand, the efficiency and energy production of solar panels is typically enhanced by cold temperatures which offsets the times when your panels are covered with heavy snow.
Winter months are actually good for solar energy production, as long as your panels aren’t covered by snow. Like most electronics, solar panels function more efficiently in cold conditions than in hot. This means that your panels will produce more power for each precious hour of sunshine during the short days of winter.
Solar panels supply dependable electricity to homes in cold climates, extreme weather and outages across New England. Plus, the more energy efficient a home is, the fewer solar panels may be needed. Finally, in a truly resilient home, batteries can store solar power even if winter weather may have gotten the best of you.
Solar power protects you and your home from winter conditions. Cold temperatures increase solar electricity production and it can be stored for future use. Plus, on a cold, clear day, there is as much sunlight as the day is long.
