Many homeowners ask: Do solar panels work in Maine winters?

With snow, short days, and freezing cold, it’s a fair concern. The reality is that solar performs reliably through Maine’s winters. Cold weather can even improve panel efficiency, and net metering allows you to bank summer energy for winter use.

In this blog, we’ll answer the most common questions about solar panel performance in Maine winters and explain why winter doesn’t stop solar from being a smart, long-term investment.

Do Solar Panels Produce Enough Electricity in Maine Winters?

Yes — a properly designed solar system will provide enough power year-round. Thanks to Maine’s net metering policy, any extra electricity your system produces in the summer is credited back to you. You can then use those credits during the shorter, darker days of winter.

At Maine Solar Solutions, we size every system based on your past usage and expected future needs (like adding heat pumps or an EV). This ensures your system produces enough to cover your annual electricity needs — including the winter months.

Will I have to remove snow and sleet from the solar panels?

No — solar panels are designed to be extremely low-maintenance. We strongly recommend against trying to clear snow or sleet yourself. Panels act much like a metal roof, quickly warming and melting snow so it slides off on its own before it can significantly affect production.

Attempting to remove snow can do more harm than good. You risk scratching or damaging your panels, which could void their long warranty. The safest and smartest choice is to let nature take care of the snow removal.

Do Cold Temperatures Reduce Solar Panel Performance in Maine Winters?

Not at all! Solar panels are built to perform efficiently in a wide range of weather conditions. In fact, colder temperatures can actually improve performance. Cooler air reduces electrical resistance, which helps your system operate more effectively.

Even in Maine winters, your panels remain reliable and productive year-round. Cold weather isn’t a drawback — it’s often an advantage.

Do I Need Solar Batteries for My System in Maine Winters?

Not necessarily. Most grid-tied solar systems in Maine are installed without batteries and still work effectively year-round. However, it’s important to understand that your solar array will not provide power during a grid outage unless you have a battery or backup generator.

If you live in an area with frequent outages, rely on critical appliances, or simply want uninterrupted power, adding a battery may be the right choice. Our team can review your goals and help determine whether a solar battery is a good fit for your home.

Can Solar Panels Be Installed During Maine Winters?

Yes — Maine Solar Solutions installs solar arrays year-round. The only weather conditions that may delay work are severe ones such as lightning, high winds, or hail.

In fact, winter can be a great time to schedule your installation. Fewer homeowners are thinking about solar during the darker months, which often means shorter wait times between signing your contract and getting your system installed.
