The static nature of solar panels doesn’t really need that much maintenance. Without any moving parts, solar hardware is perhaps the least of your worries. But sometimes, dirt and grime can accumulate on top of the panels especially in dusty and windy places. So, when it comes to cleaning your solar panels, here are some of the best recommendations from leading solar power installers.
Safety First At All Times
Cleaning anything that’s installed on your rooftop could be hazardous especially in steep angles. Unless you prefer to leave the job to professionals, make sure to put your safety first at all times. Check whether the solar panels can be detached from the metal braces or frames that hold them on the rooftop. If they are removable, cleaning is better done at the ground level. But if the hardware if fixed above, make sure you have the right equipment like a suitable ladder and extended soft brushes or cloth.
The Best Time to Clean Solar Panels
Cleaning the panels early in the morning will save you time and workload. It is because the buildup of dew on the panels has already softened whatever dirt or grime sticking on the glass surface. So there would be less brushing or scrubbing, in turn minimizing any chances of damaging the surfaces of the panels.
If you don’t have the time to do the task in the morning, choose the time of day when there isn’t too much sunlight striking on the solar panels. This prevents water from quickly evaporating from the surface, giving time for dirt to soften, making it easier to remove. You, as the cleaner, also benefit from the cooler temperature too.
Avoid Using Sharp Objects or Metallic Brushes
The reason, of course, is obvious. Solar panels, though usually protected by a thin layer of glass, can still be sensitive. Also, metallic objects can severely scratch the surface of the glass, compromising its transparency, and in turn reducing the amount of sunlight absorbed. Avoid strong or corrosive detergents too. In fact, when there isn’t that much dirt to deal with, a soft cloth and lots of water can do the job for you.
In areas where water supply is rich in minerals, squeegee-dry the surface to eliminate any chances of mineral buildup when excess water dries on the surface of the solar panel.
Lastly, Avoid Unnecessary Cleaning
When there is no need to clean the solar panels, don’t do it or even include the task in any of your routines. Ideally, wind or rain eventually removes accumulated dirt. Only when everything gets really dirty should you start cleaning the panels above. If you aren’t sure how to start off, or when you think your safety might be compromised, better call professionals or your solar power installer to do the job for you.
