Solar power is brilliant. It’s clean, renewable, and helps cut energy costs. However, when implementing renewable technology with heritage sites, high-value buildings, and tight conservation rules, additional safety considerations, especially regarding fire risks should be considered.
While fires are incredibly rare when it comes to solar PV installations, a few sensible precautions can help in mitigating fire risks in solar pv systems.
Understanding fire risks in solar PV systems #
Solar PV systems are incredibly safe when installed and maintained properly. In heritage and high-value buildings, that risk might need extra attention.
The good news? With the right design, technology, and maintenance, you can reduce fire risks to near zero.
Additional precautions required to satisfy insurers.
Limited access can make firefighting tricky.
Strict conservation rules.
Fire prevention strategies for solar PV systems #
Not all solar components are created equal. Fire-rated cables, properly tested connectors, and high-quality inverters can mitigate many issues.
A properly installed system is a safe system. Our design and installation team are accredited professionals who follow industry best practices and meet national electrical standards.
Fire-rated cables, properly tested connectors, and high-quality inverters can prevent a whole host of issues.
Arc faults (unwanted electrical sparks) are a known fire risk. Modern systems include Arc Fault Circuit Interrupters (AFCIs) that detect these faults early and shut things down before they become a problem.
Regular inspections help spot potential issues before they escalate. Dust, debris, and even small wiring faults can all be caught and fixed with routine maintenance.
A simple but effective way to improve safety. This system lets firefighters shut down the PV system immediately, either with an emergency stop button or via an automated fire alarm connection
Smarter safety with SolarEdge technology #
Traditional solar setups work as one big electrical unit, which means if there’s a problem, it can be tricky to pinpoint. A SolarEdge system however, enables detailed monitoring of each panel’s performance and system status.
For heritage buildings and high-value properties, this level of control and safety adds an extra layer of protection.
Module-level monitoring: Instead of checking the system as a whole, SolarEdge allows you to track individual panels, making it easier to spot and fix issues before they become a risk.
Automatic DC shutdown: In an emergency, SolarEdge systems automatically reduce DC voltage to safe levels, helping firefighters and reducing electrical hazards.
Arc fault detection: The system constantly monitors for signs of electrical arcing and shuts down affected components before they can cause harm.
Helping to satisfy insurers #
As with all electrical systems theres an inherent risk. Implementing these additional safety measures can help satisfy insurer requirements. By demonstrating a proactive approach to risk management, through reliable isolation switches, fire-resistant cabling, protective enclosures, and scheduled maintenance, building owners can provide insurers with the confidence that all necessary precautions are in place.

Delivering safe solar pv systems #
Solar PV is a fantastic investment in clean energy, and with the right precautions, it’s incredibly safe too. Whether it’s using fire-resistant materials, staying on top of maintenance, or leveraging smart safety technology like SolarEdge, every step counts towards making solar power as risk-free as possible.
If you’re considering solar for a heritage or high-value building, let’s make sure it’s done right.
