Commercial Solar Panel Cleaning

Greater ROI, Sooner

Serving Southern California


We have carried out solar panel cleaning on large scale ground mounted solar farms and commercial buildings across Southern California. Your solar panels are an expensive investment and it is wise to ensure they are cleaned by insured and trained professionals.

The cost benefit of keeping your panels clean makes a regular cleaning schedule a no-brainer. Increasing the power output and efficiency of your solar system by 20% or more in heavy soil areas, like farms or air traffic paths, can greatly impact your energy bill savings. If you own or maintain a commercial solar panel array, you will no doubt be interested in reaping the largest financial reward from your array and seeing your return on investment (ROI) as soon as possible. Solar panel cleaning will help you to do just that. Having dirty solar panels can severely dent your ROI timeline. By having clean solar panels, more light hits the solar cells meaning more generation which in turn means greater ROI, sooner.

We also provide a 6 point solar array health check including:

  • Professional solar panel clean
  • Inspection of the integrity of the glass of the solar panels – birds can cause breakage
  • Check the framework of the solar panels for signs of damage, warping or corrosion
  • Check the roof fixings are still intact
  • Check for signs of damage from birds or squirrels
  • Check the inverter for error codes

Google’s Research on Solar Panel Cleaning

At Google’s campus in Mountain View, CA, they have a 1.6 Megawatt Solar Panel array. Finally, after 15 months of operation, they had the system cleaned and “The energy output doubled overnight. When we cleaned them again eight months later, their output instantly increased by 36 percent. In fact, we [Google] found that cleaning these solar panels is the #1 way to maximize the energy they produce.”

Don’t Leave It To The Rain

Because rain can’t clean your panels

Looking at your windshield after a rare Southern California rain shower makes it instantly obvious why you can’t depend on rainwater to keep your solar panels clean. If you didn’t wash your windshield for 6 months, even in sunny southern California, how much visibility would you lose? If you leave your car in your driveway, the grime that accumulates will eventually “green over” as algae begin to set up shop! Even if the car is rained on, the rain contains airborne dust particles that settle and attach to the surface after the rainwater evaporates, and in Southern California calcium and hard water deposits. When using our windshield wipers, we clean the center of the screen, but where the wipers do not reach, there is a film of dirt. Your entire solar panel is in exactly the same condition as the edge of your windshield because they are both exposed to the same elements. Visibility through your windscreen is lost due to the loss of light. The same principles hold true for solar panel cleaning.

With Regular Solar Panel Cleaning

According to a study by the University of Houston, unclean solar panels can reduce energy production up to 35% and cleaning is recommended every 4 months. The financial savings of regularly cleaned solar panels are significant.

Don’t let just anyone clean your solar panels. Careless washing of your panels can have damaging and pricey results. From cracks in the glass to the seals between each panel, there are many risks when it comes to cleaning the solar panels and it’s just smart business to rely on trained, licensed and insured solar cleaning professionals.

And don’t climb your own roof without proper safety gear! Working on the roof itself is a huge hazard. The challenging task comes with the risk of personal injury or damaging the roof. This is where Premier Solar Cleaning comes in. We are your trusted, local, licensed, and insured professionals.
