Do Solar Panels Work In The Cold

The white snow can also reflect light and help improve pv performance.

Do solar panels work in the cold.

A common misconception is that solar panels produce very little energy or no energy at all during the cold snowy winter months. Many canadians are concerned about solar panels working in the snow or cold. While solar panels work best in direct sunlight they still produce energy during the cold and cloudy days. Solar panels still produce energy during the winter even if you live in an area that is cold or snowy.

Of course the output won t be as high as during those summer months where direct light is more frequent and extended but you can still make your solar panels work for you even in the coldest of winter months. But the hotter the panel is the greater the number of electrons that are already in the excited state. This reduces the voltage that the panel can generate and lowers its efficiency. Solar panels work by using incoming photons to excite electrons in a semiconductor to a higher energy level.

Solar panels do not rely on heat from a sunny day to produce electricity. This is typical of most devices and electronic equipment so it shouldn t come as too big a surprise. Do solar panels work in the winter. Even in the most frigid weather solar panels turn sunlight into electricity.

However this just isn t the case. Solar panels only need daylight to produce electricity therefore unless your solar system is blocked by shade from trees or snow it will continue to absorb. If a solar panel is extremely hot or extremely cold its efficiency does drop. What might be somewhat surprising though is that solar panels actually seem to be able to handle a bit more cold than a bit too much heat.

A common myth is that solar panels do not work during winter. Interestingly the cold temperature will typically improve solar panel output. Winter will only hurt solar production if the panels are covered with snow. While cold temperatures help solar panels convert energy more efficiently shorter days will have an impact on your energy output since solar panels can only work when there s sunlight in the sky.

Solar panels create energy from our sun s abundant. Of course snow will reduce solar energy output but over the long term the energy you lose will be very minimal. However you can increase how much sun your solar panels receive just by facing them toward the sun and tilting them seasonally. Normal weather variations like cloud cover has a larger impact on solar panel efficiency than snow does.

But research from nait shows that solar panels are more efficient in the cold and that snow has minimal impact on solar panel efficiency. The most powerful energy resource available in the world is right above your head. The solar revolution is here for you and future generations during summer sun and winter cold.
