Solar Panel Safety and Liability: Managing the Risks of Aging Solar Energy Project - Safety hazards in solar panel installations can lead to arc flash, electric shock, and liability. Learn how to protect your PV system and work environment.
The Risks of Aging Solar Projects – Safety and Liability
Solar energy projects offer significant benefits: reduced electricity costs, lower carbon emissions, and long-term energy independence. But as these systems age, so do the risks associated with them. Whether active, inactive, or abandoned, solar installations require ongoing attention to remain safe and compliant. The truth is, an aging solar project that is not properly maintained becomes a liability—not just financially, but also in terms of safety, legal exposure, and reputational damage.
Many property owners assume that the risks go away once a solar project is no longer in use. But that’s not the case. Aging systems that are decommissioned, idle, or simply underperforming can still harbor serious threats. Without consistent inspection and upkeep, aging solar projects can quickly turn from green assets into dangerous liabilities.
Over time, the modules of solar power systems naturally degrade. While solar systems are designed to be durable, neglecting regular maintenance can lead to significant safety risks and operational issues. As these systems age, performance may decline, and this decline can create safety risks that might harm people or damage property.
Even when disconnected from the grid, solar panels and inverters can hold residual electrical charge. Components degrade, increasing the risk of:
Without active monitoring and maintenance, electrical failures can occur unexpectedly and with serious consequences.
When a fire occurs in a rooftop solar system, the impact extends far beyond just the panels. The intense heat can damage the roof’s structure, especially mounting systems and racking components. The metal parts of the racking system can warp, losing their ability to hold the panels securely. This leads to falling panels, further damage to the building, and in severe cases, structural failure—endangering occupants.
The risk is particularly high when fires start in poorly maintained systems or faulty electrical connections.
Photovoltaic (PV) panels often contain hazardous materials. If these panels become damaged or are improperly disposed of, there is a risk of contamination. Neglecting to decommission or manage them correctly can result in costly environmental cleanup and legal repercussions.
Solar project owners bear responsibility for the safety of their systems. If a neglected solar installation causes injury, property damage, or environmental harm, the owner could face:
Neglecting regular maintenance can result in:
Neglecting these issues can cause lasting financial damage and safety exposure.
Proper maintenance, inspection, and upgrading are essential for managing risks in aging solar systems.
While the solar energy industry promotes clean power, it must also embrace a higher bar for occupational safety and health. Incidents like arc flash, electric shock, and rooftop fires continue to reveal weaknesses in outdated or poorly maintained systems.
Federal guidelines—especially from OSHA—should serve as a baseline for solar installation protocols. But as systems age, site-specific safety training, regular retraining, and documented inspections become critical to reduce liability and ensure compliance.
The use of personal protective equipment (PPE) like arc-rated gloves, insulated tools, and high-visibility clothing should be mandatory on any site with an aging PV system. Installers working near power lines, damaged wiring, or deactivated inverters must take extra care, especially when working on ground-mounted systems or commercial-scale solar arrays.
Solar panel safety isn't just about equipment—it’s about embedding a mindset of prevention. The solar industry must evolve from seeing safety as a checklist to treating it as a culture. That’s how we make solar energy not just clean, but safe.
Routine inspections by professionals are essential to identifying hazards and improving efficiency. Over time, components may degrade, such as:
Aging components can be replaced to extend system life, reduce hazards, and restore energy production. Replacing panels, inverters, or wiring helps reduce system stress and future liability.
If a system is no longer viable, responsible decommissioning is key. This includes:
Many older systems lack rapid shutdown capabilities. These systems allow for fast deactivation in case of emergency, preventing injury to first responders and workers.
Inactive systems—or those nearing end-of-life—should be upgraded with rapid shutdown to minimize safety risks.
On March 23, 2025, a fire at the Miramar Shopping Center in Fuengirola, Spain, was linked to a rooftop solar PV system. While the investigation is ongoing, this highlights a growing concern: solar installations are not “set and forget.”
As systems age, their risks increase—and so must our safety practices.
