How Winter Affects Solar Panel Performance

It's the season for gloomy weather, and unfortunately for solar panel owners, that means less sunlight. When winter comes around, solar power production may be reduced by as much as 30%. That may seem like a lot, but don't worry: there are ways to prepare your system for colder temperatures and maintain its output throughout the year. 

Shorter days, lower production

In the winter, sunlight is lower in the sky. This means that solar panels produce less energy than they do in the summer. Even if the sun is shining brightly on a sunny winter day, it's still lower in the sky than it is in June or July.

There are fewer daylight hours during winter too — this has a significant impact on both heating and cooling bills for your home.

Panel Temperature

Temperature affects the output of a solar panel. The higher the temperature is, the greater the amount of energy a solar panel produces. When air temperature increases during summer days, electricity production increases as well.

However, when winter comes and temperatures drop to freezing or below, electricity generation decreases by as much as 30%. 

System Efficiency

The performance of your solar panels is affected by temperature. During winter, make sure to check on your system regularly and clean solar panels when needed. The efficiency of your system is determined by the weather, so you should check it regularly and make sure things are in good shape for warmer months ahead!

During the summer, solar panels are damaged by UV rays and extreme temperatures. Keep an eye on your system during these months and make sure to clean them regularly.

Here are a few easy ways to prepare your panels for winter:

• Keep your panels clean.
• Cover them up.
• Keep them warm, if possible (e.g., with heat tape or a tarp).
• Check for snow or ice build-up on the panels, which could affect their performance and lifespan in a big way.

System Maintenance

Solar panel maintenance isn't difficult or expensive, and it's worthwhile to prevent damage.

If you pay attention to your solar panels' condition and keep them clean, you'll be able to capture more of the sun's energy for your home and reduce electricity costs.

First, check your panels regularly for any problems that occur during the colder months. Make sure there are no leaves or other debris on them that might block sunlight from reaching the cells. Also, check all connections and cables leading from the panels (especially if they're not brand new).

If you notice any problems, contact a professional solar panel maintenance company like SolarRepair as soon as possible so they fix them before they become more serious—and potentially costly.

Winter is a tough time for solar panels, but there are a few steps to take to protect them. One of the simplest ways is to keep your system healthy with regular inspections and cleaning. You should also be sure that all cables are insulated so they don't freeze in cold weather. Finally, if possible, keep your panels out of areas where snow may accumulate on top of them during winter months. These precautions go a long way towards ensuring that your solar panels perform efficiently throughout their lifetime as well as help reduce costs by allowing them to operate more efficiently throughout the year!
