Dirty solar panels are less productive in creating renewable energy.

How Solar Panels Work:

There are 4 basic steps to how a solar panel system works. So you can see if your system is operating efficiently, solar panel systems typically share the power they are generating via a digital screen on the inverter and online data indicating the monthly and annual kWh output. 

  1. Sunlight sends particles of energy called photons that are converted into electrons once they touch your solar panels. 
  2. Solar cells that make up your solar panel hardware create direct current energy (DC). 
  3. The direct current energy is sent to an inverter which converts that energy to alternating current power (AC).
  4. AC power runs through your property to power home appliances and charges devices.

Do Solar Panels Need Cleaning?

Routine cleaning is a best practice for maximizing the energy production of your solar panel system. There is no question that accumulating dirt on the surface of your solar panels reflects away light. A cleaner panel remains cooler and can convert more sunlight into energy. 

Depending on the structure and position of your panels, grime, dust, dirt, bird droppings, tree sap, and debris can build up at different levels. Flat panels need more cleaning than angled panels, and framed panels need more cleaning than frameless panels. With angled and frameless panels, rainfall can do a much better job washing away any buildup or grime as water flows off them washing away dirt without any remnants sticking to the edges. 

Solar Panel Cleaning the Professional Way:

Don’t hire amateurs for cleaning solar panels as ill-equipped contractors are known to leave mineral deposits or a soapy residue that diminishes the job by attracting more dirt and reflecting light. Even worse, amateur contractors can damage glass or cause injury if they don’t have fall protection techniques in place.

RayAccess employs IRATA certified technicians that are trained in industrial rope access. This access technique has been perfected by the oil exploration industry achieving the highest record for safety.

Besides our safety and access capabilities, RayAccess is equipped with the right tools for cleaning solar panels. We use soft-bristled brushes, water-fed poles, and deionized water. Our established protocols result in perfectly clean solar panels with no soapy residue or hard water stains.  

Environmental Factors:

The Southern California environment is a major factor driving the need for routine solar panel cleaning. Due to the dry climate, there is less rain to wash away the dust that accumulates in desert-like weather. In addition, there is less rain to wash off automobile pollutants that is part of the fabric of Los Angeles car culture.

If your property is in close proximity to tall trees or high pollen counts, bird droppings, moss, and even leaves can block solar panels from maximizing output. It pays to remove these contaminants before they build up and moss, dirt or bird droppings cover your solar panels.

How Often Should Solar Panels Be Cleaned?

Once a year as solar panel cleaning should be part of your annual maintenance checklist. Having that said, the location of your home and long periods of drought can call for more frequent cleaning needs. The actual value of cleaning solar panels is unique to each property’s situation.

Solar Panel Cleaning Cost:

Cost is based on access difficulty and the total square footage of your solar panel system. Since RayAccess is a one-stop-shop for exterior building cleaning, solar panel cleaning is usually bundled with window cleaning, roof cleaning, or pressure washing.

  • On behalf of 1033 Ocean Ave HOA, I would like to thank RayAccess for a great job in cleaning and restoring the exterior of our building. Utilizing your rope access system saved our Association much in costs and we are glad to have avoided the need to erect scaffolding to perform the work. Sergey and his crew were very professional and communicated well during the project.

  • I'm really happy with work RayAccess did for us on painting the exterior of Loews atrium. At first, I though it would be a nightmare project because of old paint condition and difficult access to some areas. But it turned out to be a very professional and smooth job! Thank you.

  • RayAccess painted our outdoor movie screen on a high-rise building in Downtown LA. With their Rope Access method, they saved us thousands of dollars in bringing a huge lift and blocking almost entire street. The job was done perfectly! Thank you so much!
