We have previously published posts on removing snow from solar panels. What about other solar panel maintenance?
Solar arrays are subjected to heat, wind, rain, hail and dust. Like windows, solar panels tend to accumulate dirt, pollen and even bird droppings.
In order to prevent build-up, which can block the rays of the sun and reduce efficiency of residential solar panels, you will need to examine and perform regular solar panel maintenance, including cleaning!
In general, people that install solar panels can “forget” about them while they generate clean, free electricity. However, just like your gutters, you’ll want to inspect and clean off panels 1-2 times each year. Most people clean solar panels in March/April and August/September before and after the winter and rainy season.
Performing regular solar panel maintenance can help you do the following:
- Maintain your investment
- Ensure peak performance
- Extend the life of your product
- Maintain product warranty.
Here are more tips on cleaning solar panels:
If you want to clean your own solar panels, without hiring a professional, you can easily do so. Simply use a regular garden hose to spray off the surface of the panels during early morning or later afternoon. This will prevent spots from forming and also ensure that you will not crack the panels during the heat of the day.
Some solar panels have automatic cleaners that you can program in advance. This works for areas of high dust and/or pollen.
When you install solar panels, check with your solar panel manufacturer regarding any specific instructions for cleaning and maintenance. For example, hard water should not be used for the cleaning. Also check to make sure there is not shading from trees, plants or adjacent buildings.
