Question 1

Does cleaning your solar panels make a difference?

Accepted Answer

While rain naturally washes away dust and soot which helps keep your panels working and absorbing sunlight, making a concerted effort to clean your panels will increase solar panel performance, increasing your financial energy savings in the process.

Question 2

How much does it cost to clean solar panels?

Accepted Answer

A professional cleaner in the Temecula Valley, Ca may charge between $150 and $300 to clean your solar panels. This varies widely based on the type of panel, how dirty your panels are, and how many panels you have. Costs range from $15-$30 per panel.

Question 3

Does cleaning my solar panels void my warranty?

Accepted Answer

Keeping your solar panels clean will not automatically void your warranty, but be sure to avoid using harsh chemicals and pressure washers or other water-fed poles that could potentially crack or otherwise damage your panels. Improper cleaning practices can sometimes void your warranty, so be sure to read the details of your contract before you jump into cleaning them yourself.

Question 4

Can you use Windex on solar panels?

Accepted Answer

Windex is a cheap and widely available cleaner that is excellent for cleaning glass surfaces such as those on solar panels to ensure they run efficiently.

Question 5

Is it okay to pressure wash solar panels?

Accepted Answer

While they may be suitable for cleaning other parts of your home, you should never use a pressure washer on solar panels to avoid damaging them and creating cracks.

Question 6

How often should you clean your solar panels?

Accepted Answer

You should clean your solar panels about every six months. Of course, the frequency of solar panel cleaning depends primarily on where you live. For example, if you live somewhere where it rains a lot, you may need to clean your panels less often than if you live somewhere dry and dusty where debris builds up more quickly.
