Preparing Solar Energy Systems for Autumn Weather

As summer transitions into autumn, leaves start to fall, rain is more frequent, and chillier temperatures spread across the Northwest. This sweet period between the brutal heat of summer and the bitter chill of winter is a great time to prepare your home or small business for the change of seasons. While the solar industry focuses on the importance of transitioning your solar panels between summer and winter, there are some things you can do to maximize your solar energy capture during autumn. Here are a few tips for efficient Idaho solar power during fall months:

Fall Cleaning

If your PV solar panels are covered by leaves or debris, that can affect your system’s ability to charge throughout the day efficiently. Clearing PV solar panels of seasonal outdoor debris is a good way to ensure your panels are able to receive enough sunlight to convert the energy you need. Professionals often suggest waiting until mid-autumn to clear panels.

However, if you see that your panels are dusty, they don’t necessarily need a power wash. Even the dustiest solar panels only lose about 7% of their efficiency. So it could be worth waiting until spring to clean them, especially since hiring a professional can be a hassle. When you install solar panels on your building, ask the solar Idaho company the type of maintenance they provide.

Adjust Tilt

The angle of sunlight that you receive changes depending on the season. The difference between summer and winter can be a 30-degree difference, depending on your location. For areas like southern Idaho that fall between 42 and 45 degrees latitude, 37 degrees is the optimal angle for the best energy efficiency. In summer, 12.5 degrees is best while 59.6 is preferred for winter months.

That 37-degree sweet spot can totally increase your PV solar panels' ability to charge what you need. Taking advantage of solar Idaho efficiency can positively affect your transition from summer to autumn and autumn to winter.

Power Systems

The outdoor temperatures during autumn influence how people often use heat or air conditioning. Unlike summer, which relies on air conditioning, or winter, which requires heat, autumn is more neutral temperature-wise. Be conscious of how you’re using your power during this transitional time. Using your air conditioning less can be a benefit to your energy usage and power bill. Try to wait as long as possible before turning on your furnace.


As the days get shorter, the longer you’ll be using electric lights indoors. Switch out your traditional bulbs for energy efficient LED lights. Shorter days also means that your panels have less time to receive sunlight, but conserving your power usage around the house makes this transition easier.

Asking a solar representative what your solar energy solutions require during this seasonal transition is the best way to know what your specific needs may be. EvenGreen Technology provides consumer education about energy efficiency with reliable sources and industry experience.
