EVERYTHING YOU NEED TO KNOW...

Solar panels are a great investment that can provide you with renewable solar energy for the next 25 years or more. But how do you maintain them? Are they like your car, requiring regular tune-ups to stay in peak condition? Or are you supposed to just leave them be? Read on for answers to the common solar panel maintenance questions.

DO SOLAR PANELS NEED TO BE MAINTAINED?

Solar panels generally require very little maintenance in order to function. The only thing they need is a periodic light cleaning to make sure dirt, leaves, and other debris aren't obstructing the sun's rays. The only time you may need more extensive maintenance is during periods of heavy snowfall, or if your panels' energy output starts to decrease. Let's take a closer look at how to make sure your solar panels last as long as possible.

HOW DO YOU MAINTAIN SOLAR PANELS?

If your panels are tilted, you’re in luck: rainfall actually clears away debris that's accumulated on them. However, during the dry season or extended periods without rain, it's important to clean them manually. It is generally recommended that you perform solar panel cleaning between two and four times per year. The good news is that this doesn’t require much work.  All you really need is a leaf blower or a quick spray with a garden hose, and your panels will be clean and in top condition.

In winter, you may need to clean your panels after a heavy snowfall. If you're using water to clear the snow away, make sure it's lukewarm. You can also use a squeegee with a long handle. Just remember, never use hot water when clearing snow off the panels. The panels are made of tempered glass, and the extreme temperature disparity between hot water and cold panels can crack them.

GROUND PANELS VS. ROOF PANELS

IS THERE A MAINTENANCE DIFFERENCE?

The only real difference between maintaining ground-mounted solar systems and roof solar systems is that ground panels are easier to access, and therefore easier to keep clean. If you notice a buildup of snow or other debris, you can simply sweep it off with a broom.
