Cleaning Solar Panels
Solar panels on your property will occasionally need to be cleaned to keep them functioning and performing at full efficiency. Cleaning solar panels will improve their efficiency, durability, lifespan, and aesthetic appeal and may even be a condition of your warranty.
The only way to ensure that your solar panels are clean is to perform the task yourself or hire a local solar company to do it for you.
Cleaning Solar Panels – Getting Started
There are several methods to clean your solar panels. Here are a few conceptual guidelines to help you get started.
When cleaning solar panels:
- Use materials like soft sponges and scrubbers that won’t damage the panels and inhibit the performance of the photovoltaic cells.
- Do not pressure wash your solar panels! The high pressure can remove protective sealants and even dislodge the array.
- It’s best to avoid cleaning your panels during the hottest part of the day, as the temperature difference between hot panels and colder water could cause the panel to crack.
Cleaning Solar Panels
Simply put, an effective way to clean your solar panels is similar to washing your car. Use a bucket of soapy water and a non-abrasive sponge to loosen dirt and debris. From there, spray the panels down with the hose very gently. However, you need to make sure not to use a high-pressure sprayer or even a high-pressure attachment on your regular hose; again, this can damage the solar panels.
If you want to use a cleanser on your solar panels, you can make one yourself with diluted vinegar. Many cleansers are too corrosive to be safely used on solar panels. However, a mixture of 50% white vinegar and 50% water will dissolve mineral deposits without harming panels.
Should I Clean My Solar Panels Myself?
While these tips will help keep your solar array clean, many homeowners opt to have professionals routinely do it for them; there are several good reasons for this. For one thing, you might not be comfortable getting up on the roof to gain access to the panels.
Also, many people would rather have a trained professional work on their solar equipment so as not to risk damaging their system.
Of course, the time of year, the local weather patterns, and various environmental factors will determine how often your panels need cleaning, and local solar panel installers will be able to advise on this.
