Spring Cleaning Your Solar Panels

This entry was posted in Solar Services on by .

As we approach the spring months, many of us turn our attention to cleaning, organizing and home improvement projects. If your home has a solar power system, you may want to add your solar panels to your spring-cleaning list.

Covered by a protective glass coating, solar panels are constructed of solar cells that require sunlight function. Thus, the dirtier and dustier the glass gets, the less sun exposure will reach the cells. In other words, your system will generate less power if the panels aren’t clean.

In the greater Phoenix area, dust isn’t in short supply. And, it only takes one good wind storm to leave an impressive amount of dirt on rooftop panels. Over the course of months, the buildup can actually reduce your power production. This is one reason why it’s always a good idea to monitor your system’s performance, as well as the glass surfaces of the panels to ensure they’re free and clear of:

  • Dirt
  • Dust
  • Leaves
  • Bird droppings

Cleaning Solar Panels

To clean panels, do it in the early morning hours when the sun isn’t heating them up. Use a water sprayer and only a squeegee, soft cloth or sponge. Avoid using scouring pads, metal tools and abrasive detergents or cleaners which can scratch the glass. Of course, be careful when cleaning panels, particularly if you’re climbing onto your roof. Your best bet is to clean the panels from the ground, using a garden hose with a sprayer attachment.

With regular maintenance, your solar power system will provide many years of power generation, saving you thousands on your utility bills.
