Why Solar Panel Cleaning Safety Training in America Is Compulsory

This is the biggest mistake in the market.

Solar panels are not just dirty surfaces. They are part of an electrical generating system. OSHA’s own solar guidance says workers in the solar industry can face arc-flash hazards, electric shock, falls, and thermal burn hazards that can cause injury or death. OSHA also says maintenance work on solar panels is generally treated under general-industry rules, and workers exposed to fall hazards of 4 feet or more must be protected.

OSHA-hosted solar electrical training material also says that any time PV modules are exposed to sunlight, they will produce voltage. That is why “we shut it off” is not the end of the conversation in PV work. Solar cleaning is not ordinary window cleaning with a different surface. It is work around an electrical system that can still present danger.

The first layer is the General Duty Clause of the OSH Act. Employers must furnish employment and a place of employment free from recognized hazards that are causing or are likely to cause death or serious physical harm. That duty applies whether the hazard comes from a production line, a roof edge, or a live PV array.

The second layer is OSHA’s electrical training rule, 29 CFR 1910.332. It says the training requirements apply to employees who face a risk of electric shock that is not reduced to a safe level by the installation rules. OSHA interpretation letters also make clear that workers facing electrical hazards must be trained in electrical safety-related work practices, and that when people work on or near exposed energized parts they are treated as either qualified or unqualified persons. In a public enquiry regarding electrical hazards at work, an OSHA representative responded with the following:

“According to subsection 1910.332(a), employees who face a risk of electric shock or other electrical hazards that are not reduced to a safe level by the electrical installation requirements of sections 1910.303 through 1910.308, must be trained in electrical safety- related work practices as required by sections 1910.331 through 1910.335. By subsection 1910.332(a), employees are delineated as either qualified persons or unqualified persons when working on or near exposed energized parts. Qualified persons have training, whereas unqualified persons have little or no training, in avoiding the electrical hazards of working on or near exposed energized parts. This capability includes familiarity with the proper use of special precautionary techniques, personal protective equipment, insulating and shielding materials and insulated tools. Also, this capability includes familiarity with the construction and operation of the equipment and the electrical hazards involved, in accordance with the definition of qualified persons in section 1910.399.“

The third layer is 29 CFR 1910.333. OSHA says live parts to which an employee may be exposed shall be deenergized before the employee works on or near them, unless the employer can show that deenergizing creates added hazards or is infeasible because of equipment design or operational limitations. OSHA also explains that if live parts remain exposed, only qualified persons may work on or near them.

Then comes PPE. 29 CFR 1910.132 requires employers to train employees on when PPE is necessary, what PPE is necessary, how to use it, its limitations, and its care. OSHA says each affected employee must demonstrate understanding and the ability to use PPE properly before being allowed to do the work.

Then comes fall protection. 29 CFR 1910.30 says that before any employee is exposed to a fall hazard, the employer must provide training, and that training must be given by a qualified person. OSHA’s solar guidance says maintenance work on solar panels generally falls under general industry and that workers exposed to fall hazards of 4 feet or more must be protected.

So the legal point is simple. OSHA does not need to publish a rule titled “solar panel cleaning” to require training. If the work brings electrical exposure, PPE requirements, and fall hazards with it, the training duties are already there.

This is where many contractors get into trouble.

It is not enough to say, “My guys are experienced.”

It is not enough to say, “We already clean windows.”

It is not enough to say, “We use common sense.”

OSHA’s interpretation letters say qualified persons must have training and be familiar with precautionary techniques, PPE, insulating and shielding materials, and insulated tools. That means competence is not just confidence. It is not a sales claim. It is something that should show up in training records, procedures, supervision, and equipment choices.

Responding to a public enquiry about electrical P.P.E., an OSHA representative responded “Paragraph [1910.335(a)(1)(i)] requires employees to use appropriate electrical protective equipment (which includes rubber insulating gloves) when working in areas with potential electrical hazards. Whether an employee needs to wear rubber insulating gloves while working with test equipment on energized circuits will depend on several factors including: ‘Whether there are other exposed energized parts that the employee’s hand might contact during testing.’ According to paragraph 1910.332(a), employees who face a risk of electric shock from electrical hazards that are not reduced to a safe level by the electrical installation requirements of sections 1910.303 through 1910.308 must be trained in electrical safety-related work practices as required by sections 1910.331 through 1910.335. By paragraph 1910.332(a), employees are either qualified persons or unqualified persons when working on or near exposed energized parts. Qualified persons have training, whereas unqualified persons have little or no training, in avoiding the electrical hazards of working on or near exposed energized parts.”

That is why formal solar safety training matters. OSHA does not name one mandatory provider, but it absolutely expects the underlying competence to exist. In the real world, the clearest way to prove that competence is through documents: training records, certificates, job procedures, PPE records, hazard assessments, and evidence that workers were trained for the exact task they were doing.

Think about it plainly.

Would a serious employer let an untrained worker open energized equipment and just “be careful”?

Would a legitimate electrical contractor let an unqualified person work around exposed energized parts because he is “good on ladders”?

Of course not.

OSHA’s framework draws a hard line between qualified and unqualified people when electrical exposure is involved. Solar panel cleaning should not be the loophole sector where people pretend electricity somehow does not count because the work is sold as “just cleaning.”

This is not theory.

In one OSHA case, a maintenance worker suffered an electrical shock while changing a ballast, fell about 6 feet from a ladder, and later died from his injuries. OSHA said the employer required employees to do the work without proper lockout/tagout training, failed to maintain an electrical lockout/tagout program, failed to ensure only qualified persons worked on live circuits, failed to provide PPE, and failed to keep workers off live parts. OSHA called the death preventable.

And in solar itself, OSHA is already enforcing fall rules aggressively. In December 2024, the Department of Labor said Sunrun Installation Services was cited after investigators found workers exposed to deadly fall hazards at two solar jobs within three months, with proposed penalties of $288,087. OSHA’s release also pointed to fall protection and worker training. That was not a cleaning case, but it proves the larger point: solar work is not getting a free pass in America.

So contractors need to stop saying, “OSHA hasn’t written a solar cleaning rule yet.” OSHA does not need a special solar-cleaning title to ask the questions that matter: Was the hazard recognized? Was the worker trained? Was fall protection in place? Was PPE required and properly used? Was the person qualified for the electrical exposure involved?

Insurance is not a magic shield, and solar cleaning is not an easy risk for every carrier to stomach.

U.S. renewable-energy insurance literature has noted for years that the market for certain PV insurance products can be thin or non-existent, and more recent hard-market commentary has described shrinking coverage and fewer coverage options for solar risks. In plain English, that means not every insurer wants this class of work, and the market can tighten fast. This is proving to be true in the solar panel cleaning sector. Some insurers who offered solar panel cleaning policies, no longer do so.

That matters because some contractors still assume they can simply bolt solar cleaning onto a window cleaning or pressure washing policy and hope that is enough. That is a dangerous assumption. General liability policies are underwritten by the type of work the business does. The Hartford explains that general liability class codes are used to group businesses by what they do and how risky that work is, and it specifically says that if a company performs work outside of its industry class, an insurer may not cover the claim.

That is exactly why a window cleaning, pressure washing, or generic exterior-cleaning policy should never be assumed to cover solar panel cleaning unless solar work has been specifically disclosed to the carrier and accepted into the policy. Solar cleaning is not just another pane of glass. It adds electrical exposure, rooftop fall exposure, different equipment issues, and a very different loss profile. The existence of dedicated solar contractor insurance products is itself a sign that insurers treat solar as its own class of risk, not as an automatic extension of ordinary cleaning work.

It gets even tighter when policies contain classification limitations or designated-operations language. Insurance guidance on classification limitation endorsements explains that they narrow a business’s coverage to the operations specifically cited in the policy, and that no coverage is provided for operations not specifically listed. So if a policy is written around window cleaning or pressure washing operations, and solar panel cleaning has not been declared and accepted, a solar loss can very quickly turn into a denial fight.

And a certificate of insurance does not rescue you from that problem. New York DFS explains that an ACORD certificate is not a contract and may not amend, expand, or alter the terms of the policy. In other words, having a certificate in your hand does not magically create solar coverage if the underlying policy never actually covered solar cleaning in the first place.

There is also the application problem. NAIC materials explain that a material misrepresentation is an untrue statement that is material to acceptance of the risk and would have affected the insurer’s decision or rate, and that rescission can be the remedy. So if a business presents itself as simple window cleaning or exterior washing but is in fact sending crews onto energized PV rooftops, that is not a minor detail. It can become both a safety issue and a coverage issue.

So the careful and honest U.S. position is this: not every safety breach automatically wipes out every policy, but solar cleaning is a higher-risk activity that not every carrier wants, that some markets treat cautiously, and that should not be assumed covered under a standard window cleaning or pressure washing policy. If solar cleaning is not clearly disclosed, classified, and accepted, a serious loss can become a very ugly insurance fight very quickly.

The solar cleaning industry needs to stop asking:

“Where does OSHA say I need a solar cleaning certificate?”

That is the wrong question.

The right question is:

If one of my workers is shocked, electrocuted, falls from height, causes injury, or causes a fire, how will I prove to OSHA, to a client, to a court, and to an insurer that this person was properly trained and competent for the work?

If that cannot be answered clearly, and with documents, the contractor is exposed.

Solar panel cleaning safety training in America is not a nice extra. It is not just a marketing badge. It is not something to think about after an accident.

If you are cleaning solar panels, you are working around electrical hazards and usually fall hazards as well. OSHA’s rules already require training, qualified-person controls, PPE training, fall-hazard training, and safe electrical work practices for that kind of work. The only thing OSHA does not do is pick your training provider for you.

No serious industry should allow live electrical work around rooftops, water, conductors, and fall exposure without formal training and proof of competence. Solar panel cleaning should not be the exception.
