Commercial Solar Panel Cleaning

While rain might wash away surface-level dust, it won't be enough to properly clean your solar panels. Much like a car left in a storm, rainwater can't remove stubborn grime, bird droppings, tree sap, or oily residue. Over time, this buildup—along with hard water stains left after the rain evaporates—will prevent your system from absorbing maximum sunlight, reducing its efficiency. To keep your solar panels operating at their best, they need routine, professional cleaning to safely wash away this tough buildup.

Advanced Solar Cleaning carries insurance beyond the basic. We carry General Liability, Excess Liability, Worker's Compensation, Commercial Vehicle and Equipment insurances. We generate all site-specific COI's prior to starting work on any site.

• $1M (Per-Occurrence Limit): The maximum amount the insurance company will pay for a single, individual claim or incident.

• $2M (General Aggregate Limit): The maximum amount the policy will pay for all claims combined during a single policy period (usually one year).

• $5M (Umbrella/Excess Liability): Additional, higher-level coverage that kicks in to cover losses that exceed the $1M/$2M primary policy limits.

A buildup of dust, grime, and debris can cause your solar panels to lose 15% to 30% of their efficiency. This layer of dirt blocks sunlight from reaching the solar cells, leading to a significant drop in power production. Regular professional cleanings can reverse this problem by washing away stubborn buildup. This helps you maintain optimal energy output and ensures your system operates at peak performance all year round.

At Advanced Solar Cleaning, the safety of our employees, customers, the public, and the property in our care is our highest priority. Before any work begins, each site is thoroughly analyzed for potential hazards and environmental risks. Based on this analysis, our safety managers develop a detailed written plan, which is discussed in-depth with our technicians and remains accessible to them throughout the project.

We are committed to maintaining a well-trained team. All ASC technicians are required to be OSHA 10 certified, while all managers, supervisors, and foremen must hold an OSHA 30 certification. This is complemented by weekly tailgate safety meetings where we address common exposures and job site-specific dangers to ensure a safe working environment.

Many factors influence how often your solar panels need cleaning, including traffic volume, local environment, flight paths, and nearby wildlife.

For instance, if your panels are near open fields with loose dirt, we recommend quarterly cleanings. If they're close to a busy road where dirt, debris, and oils can accumulate, a minimum of two cleanings per year is advisable.

We also suggest visually inspecting your solar array monthly to monitor any buildup. You may also check the manufacturers warranty language to determine the suggested cleaning frequency. This is especially important so you don't lose your warranty.

No problem! ASC has the capability to deliver water to most commercial solar cleaning job sites with a minimal up-charge. Water available onsite is always preferred, but not necessary.

As early as same day for most single properties (i.e. warehouses, carport canopy parking lots). Although, for most asset manager with multi-site portfolios, it can take up to 2 weeks depending on the volume of sites.

ASC does a deep dive into all factors while bidding Commercial Solar Cleaning, so this can extend RFQ lead times based on volume.
