How to Protect Solar Panels From Freezing

Solar panels take energy from the sun and convert it into electrical energy that can be used by homes and appliances.

While solar panels are not currently very efficient---meaning they receive a lot more light energy than they convert to electrical energy---they are very useful in lowering overall power costs and are environmentally friendly as well. Solar panels do require maintenance to keep them in peak form, though, and they need to be kept safe from freezing in the winter. Luckily, this is not difficult to do.

Enable the frost protection circuit if your system has one available. A sensor will detect when the temperature is dropping to where frost is a risk and will activate a heat pump that will warm the panels enough to where frost can't form.

Apply glycol to the panels in accordance with manufacturer instructions. Glycol can usually be applied with a soft brush. It works by lowering the freezing point of the panels so frost can't form under normal weather conditions. It is a main component in engine antifreeze for the same reason.

Cover the panels with a protective cover in the event of heavy snow. Some automated solar panel types open and close automatically.
