Many people wonder what happens to solar panels and their performance when the winter
months hits. But you have nothing to worry about. The cold temperature will typically
improve solar panel output. 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 are built at an angle to optimize the intake of the sun’s UV rays, which also helps to reduce snow build up as the majority of snow can slide off or be easily removed. You can take control of the situation by getting a solar panel snow rake or similar tool made for solar panel snow removal that won’t damage the panels.
There are a few things you need to make sure you know about your solar panels in winter
- All solar panels are designed to bear a certain amount of weight and snow will usually not be heavy enough to cause issues.
- If snow covers your panels, they can’t produce power – but it’s easy to clean them off with the right equipment.
- Cold, sunny weather is actually good for panels. 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.
