HOW TO CLEAN YOUR SOLAR PANELS
First: switch your system off by following the instructions in the inverter manual. If you collect water from your roof for drinking, you may want to consider blocking or diverting the roof water while you clean.
Next, check to see if there is any visible damage to the solar panels. Do not touch any of the cables or connection. If you see any damage, soot marks or rust marks on the panels, cables or isolators, don’t touch anything and contact a professional. If there is no visible damage, start to clean the panels from above using plain water (no chemicals or detergents). The best way to clean solar panels is to use a soft broom with a hose attachment as featured in our Solar Panel cleaning video above. But you can just use a sponge.
Never use a pressure washer as this can damage the panels and void the warranty. You should never walk or lean heavily on the solar panels as this can create micro cracks in the panels, which can lead to significant reduction in the performance of the solar system. It can also void the warranty of the system. Most panels will clean easily without hard scrubbing, you can use a flat Stanley blade to remove stubborn marks like bat and bird droppings. Avoid wetting underneath the panels as this is where most electrical connections are. Remember that water and electrics don’t mix well and can become very dangerous with the inclusion of solar panels.
When the panels are clean and the roof is dry, it is a good idea to have a closer look at the panels so you can inspect for fine damage like microcracks and hotspots. These are not always visible, but overtime may start to appear as a small burn mark on the front or back of the panels. Or you may see what likes a snail trail across the panel; if this is visible it’s time to call a professional.
Some damage may be covered by warranty on your panels but if it’s deemed the panel was damaged by poor installation practices (which is unfortunately common these days), you may find your warranty will not cover it. This is why it’s important to do your research and decide on a reputable, trustworthy solar company.
