Key Points
- Solar panels produce electricity even in cold-weather states.
- Removing heavy snow from solar panels increases the risk of scraping and damaging the panels.
- Panel cracking and fracturing can occur from snow melting and freezing.
- Silicon-based photovoltaic solar panels work more efficiently in cold climates.

Solar panels in the winter FAQs
Yes, solar panels still work in cold weather states. In fact, many cold northeastern states, such as Massachusetts, Vermont, and Maine, rank high for solar power generation.
The performance of solar panels may decrease in freezing temperatures. They are typically designed to operate within a temperature range of -40 degrees to +185 degrees Fahrenheit. Make sure to check with your solar manufacturer to confirm the temperature range for your panels.
Solar panels produce less energy in winter than in other seasons due to shorter daylight hours and lower sun angles. The exact reduction will vary depending on location, weather conditions, and panel orientation. However, the general estimate is around 20–30% less production when panels are covered in snow.
