Why commercial solar is changing accountability, insurance and emergency readiness
Commercial solar is no longer simply an electrical installation sitting on top of a building.
Once a PV system becomes operational, it becomes part of the building’s wider risk environment — alongside people, stock, production, maintenance, insurance, fire safety and business continuity.
And in many commercial installations, those responsibilities do not belong to the same organisation.
- The property owner may own the roof.
- A tenant may operate the business underneath it.
- A third party may own the solar asset.
- An EPC may have installed the system.
- A separate O&M contractor may now maintain it.
- Specialists may carry out thermography, cleaning, roof work or electrical repairs.
- And different insurers may respond to the property, solar asset, stock, liability and business-interruption exposures.
None of this is necessarily unusual.
The challenge begins when those parties do not have the same information.
One site. Several responsibilities.
A commercial PV installation can therefore create a deceptively simple question:
Who actually owns the risk?
The answer may be different depending on what has happened.
- Who receives a warning after an inspection?
- Who has authority to shut the system down?
- Who can approve re-energisation?
- Who receives a thermography report?
- Who confirms that corrective work has been completed?
- Who updates the emergency plan when the installation changes?
- And who makes sure that the tenant or business operating underneath the system understands what has happened above them?
These are not merely technical questions.
They are questions of accountability.
A CoC is important — but the story continues
A Certificate of Compliance and proper handover are essential controls.
But they represent a point in time.
The system continues operating afterwards.
- Components age.
- Weather takes its toll.
- Roofs are worked on.
- Panels are cleaned.
- Contractors change.
- Equipment is repaired or replaced.
- Batteries may be added.
- A tenant may change.
- Ownership may change.
- And defects or near misses may occur.
- The risk position today may therefore be very different from the risk position on the day the system was commissioned.
That is why the ongoing evidence matters.
“Back online” is not necessarily “closed out”
A repair can restore generation without necessarily resolving the underlying safety question.
- Was the cause understood?
- Was similar equipment inspected?
- Was the responsible party informed?
- Was the repair verified?
- Was the finding formally closed?
- Were any emergency or isolation arrangements affected?
- Could somebody reviewing the site a year later reconstruct what happened?
This distinction is important because a contractor’s completed invoice does not necessarily mean the site’s risk has been fully addressed.
The information has to reach the person who carries responsibility for the risk.
The information chain is itself a safety control
The first person to identify a problem may not be the person who owns the system.
- A cleaner may notice damaged cabling.
- A thermographer may identify an abnormal hot spot.
- A technician may replace a connector.
- A roofer may disturb equipment or access arrangements.
- A fire warden may discover that emergency information is outdated.
- The critical question is what happens next.
- Does the observation travel through a defined chain?
- Does somebody with authority receive it?
- Is action assigned?
- Is it verified?
- And does that information remain available afterwards?
Where the information chain breaks, an accountability gap begins.
A recent international case illustrates the questions
The 2026 Boyle Heights warehouse fire in Los Angeles is useful not because outsiders can use the public record to assign technical blame, but because it illustrates how quickly different areas of responsibility can intersect.
The fire occurred at a large cold-storage warehouse in June 2026, with prolonged firefighting and overhaul. The Los Angeles Fire Department ultimately classified the precise initiating cause as undetermined; public reporting described an electrical event in the area of origin, while the specific cause could not be conclusively established.

Public reporting also identified different parties connected with the property and warehouse operation, the rooftop PV asset and specialist solar work. An earlier rooftop solar-panel fire had also been reported at the location in 2024. LTV_Article_The_Roof_Is_Not_A_S…
The useful lesson is therefore not to speculate about who was responsible.
It is to ask what information a property owner, insurer, EPC, risk assessor or investigator would want immediately available after an incident.
- Who had authority?
- What happened previously?
- What work was performed?
- Who received the findings?
- What was verified before returning equipment to service?
- And what information was available to emergency responders?
Those are the questions that matter.
Prevention, mitigation and emergency readiness all matter
PV risk cannot be managed through one control alone.
Prevention remains essential: competent design, installation, inspection and maintenance.
Mitigation is also necessary: protective measures, appropriate escalation and an understanding of isolation.
And emergency readiness matters when something has already gone wrong.
Facilities teams, health and safety personnel, fire wardens and responders need usable, current and site-specific information.
A technically sound installation does not replace an emergency plan.
An emergency plan does not replace maintenance.
And an inspection report achieves very little if the findings disappear into an inbox.
Where PVRX fits into this discussion
These recurring gaps are part of the reason LTV Technologies & Supplies has been developing PVRX — the PV Risk Index.
The objective is not to replace installers, engineers, insurers, risk assessors, maintenance providers or emergency professionals.
It is to help bring the information surrounding the PV risk together in a more structured and usable way.
PVRX is being developed around the principle that the risk surrounding a PV installation should remain visible beyond the original handover as the site, the system, responsibilities and available evidence change.
The underlying methodology is still being developed and requires technical input, industry engagement, suitable evidence and appropriate validation.
That work is progressing in consultation with stakeholders, technical partners, OEMs and insurance and risk professionals.
We believe the experience accumulated across PV safety, training, technical work and emergency-response engagement provides a strong foundation.
But this is also not intended to become a static exercise.
Just as a CoC provides an important starting point rather than the final chapter in the operating life of a system, the way PV risk is assessed will need to continue developing as industry experience and evidence grow.
Technology alone will not close the gaps
This is equally important.
A platform cannot compensate for poor training, unclear responsibility or inadequate maintenance.
PVRX will only be valuable where the people using it understand their roles and where the information being captured is reliable.
The broader solution therefore remains a combination of:
competent technical work, good handover, ongoing inspection and maintenance, clear accountability, appropriate training, effective escalation, evidence of corrective action and realistic emergency preparedness.
Technology can help connect those elements.
It cannot replace them.
The conversation we want to continue
LTV is currently engaging with people across different parts of the risk chain.
That includes PV professionals, property stakeholders, risk assessors, insurers, OEMs, safety practitioners and emergency-response stakeholders.
We are particularly interested in one question:
If a serious PV incident occurred at a commercial site tomorrow, could the responsible people quickly establish what is installed, who is responsible, what happened previously, what remains outstanding and what action is required?
If the answer depends on searching through several contractors, old reports, email inboxes and disconnected records, there is still work to do.
That is the gap we believe the industry now needs to address.
