Setting Up Solar Panels in Regions with Cold Weather
Solar panels require large, consistent amounts of sunlight to generate energy. Most people associated sunlight with warm climate and summer
But what about areas that experience cold weather and heavy snowfall? Is it recommended to install solar panels in such locations? Find out below.
Performance in Cold Weather
Solar panels perform well in areas that experience cold climates during the year because the units do not rely on the sun’s heat (instead utilizes the sun’s light) for energy production. Furthermore, cool temperatures reduce the possibility of overheating, which contributes to overall performance in panels and other parts of the system. Solar panels installed in cold-climate regions are less likely to exceed their peak temperature rating. It is important to point out that at temperatures above 77F, solar panels start to lose efficiency.
Things to Consider
Locations that experience heavy snowfall during the winter may have to check on their panels periodically. When snow accumulates on panels, it can block sunlight and decrease efficiency. Using a padded snow rake to remove snow and other obstructions from panels is an effective solution for such issues. Pads the hard bristles prevent scratching on the surface off the units. In areas that are prone to light to mild snowfall, ensure a slightly tilted position to naturally move melted snow and ice away from the panels.
Although solar panels perform well in cold climates, their connected battery bank may not (depending on the type of power cells of the system). Deep cycle batteries must be kept at mildly warm operating temperatures to ensure capacity. On the other hand, lithium-ion and sealed lead acid solar batteries do better in cold environments. To prevent temperature-related issues with batteries, it is recommended to install them indoors, such as garages or sheds, where temperatures can easily be set.
