4 Reasons Why You Need to Get Your Solar Panels Cleaned in the Fall

4 Reasons Why You Need to Get Your Solar Panels Cleaned in the FallFall has finally arrived. The days are getting shorter, the nights colder, while the leaves are turning orange and brown before falling from the trees. Yet there is more that you do during the fall than watching nature transform from one season to the next – namely taking care of your solar panel maintenance.

Solar panels need regular cleaning throughout the year to keep working at maximum efficiency, as all kinds of dirt and debris accumulates over the seasons. While many leave their cleaning to the warmer seasons like spring and summer, it’s always recommended that you clean them at least once during fall!

Here’s 4 reasons why you need to get your solar panels cleaned in the fall!

Fall Foliage

The most obvious reason to get your panels cleaned during fall is all those beautiful leaves. Yes, they look amazing on the trees but once they start falling, they’ve got to go somewhere, with many ending up on the roof and covering your solar panels.

This is especially true for anyone living near wooded areas or with trees next the house, with leaves accumulating all over the surface area of panels. As a result, panels are blocked from the sun so can’t absorb as much energy, making them less efficient and giving your home less energy.

Plus, while you’re cleaning away leaves from the panels you can also clear the roofing and gutters while you’re at it – that or call in professional cleaners to get the job done for you.

Bird Droppings

Those same trees with all the leaves falling from them also have some other problems for panels – birds. When there are birds near your home that also means there’s going to be droppings nearby, some of which is likely to cover your panels.

Fall sees a lot of bird migration too, so you may even find bird populations fluctuate around your area. This increased activity often comes with a lot of noise and, you guessed it, droppings. These can make solar panels far less efficient and are hard to remove naturally, so a good cleaning is recommended.

The Lasting Effects of Summer

Summer is over and there is a good chance that the warmer months resulted in lots more dirt and dust accumulating on the panels.

This is especially true if you live in drier climates that haven’t seen much rain, so it’s helpful to get the panels cleaned after long, dry summers to remove excess dirt and dust that may be blocking light passing through the panels.

Less Sunlight

Getting solar panels cleaned usually sees them get a bump in efficiency, so it’s worth doing at any time of the year to get the most from them. However, fall is possibly the most important time to get these cleaned, as the days are getting shorter so there is less sunlight!

Less sunlight means less power being gathered by the panels, so you want them working to their maximum efficiency during fall so that you can offset the loss of daylight.
