Improper Plug-in of Solar Panels Poses Shock Hazards and Fire Risks,
Solar Expert Warns
As solar energy becomes increasingly popular in the UK, the associated risks of improper installation and maintenance are also rising. Solar panels, like any electrical system, can pose significant hazards, including fires and electrical shocks, if not properly managed.
Recent data highlights a worrying trend: the UK has seen a sharp increase in solar panel fires, with a six-fold rise over the last decade. In the first half of 2023 alone, 66 fires were reported, surpassing the total number for 2019. According to the UK Government, Fire and Rescue Service's 2024 report attributes many of these incidents to faulty installations.

Inemesit Ukpanah, a solar expert at GreenMatch, emphasises that poor installation practices and substandard equipment are significant contributors to these fires. DC isolators, in particular, have been identified as a significant fire risk linked to 26 out of 80 investigated incidents.
To help homeowners prevent solar panel fires and ensure safety, Ukpanah offers the following guidelines:
1. Choose quality products and Hire a Certified Installer.
Always use a professional, certified installer registered with a reputable industry body, such as the Microgeneration Certification Scheme (MCS). Most fire risks stem from electrical issues, so qualified electricians should handle all connections. Verify their credentials by checking online directories or asking for proof of certification. Read customer reviews and ask for references to ensure they have a track record of successful installations. Uncertified installers may lack the necessary skills and knowledge, increasing the risk of improper installation.
2. Avoid DIY Installations
While DIY solutions may seem cost-effective, they can lead to dangerous situations if not done by a trained professional. The potential risks far outweigh the savings. DIY installers often underestimate the complexity of solar panel systems, leading to errors such as incorrect wiring, inadequate mounting, and improper electrical connections. These mistakes can cause safety hazards, reduce system efficiency, and lead to costly repairs.
3. Use Quality Materials
Opt for solar panels with UKCA marks, indicating they meet UK safety standards. Ensure all components are high-quality and meet these standards to avoid future problems. Investing in high-quality materials reduces the risk of system failures and extends the lifespan of your solar installation. Quality components are more reliable and often come with better warranties.
4. Ensure Proper Connections and Regular Maintenance
Use DC connectors from the same manufacturer to prevent electrical arcs. Schedule regular maintenance checks to catch potential issues early. Incompatible parts can lead to increased resistance and potential fire hazards. Moreover, keeping panels free from debris is important to avoid hot spots.
5. Check Your Insurance
Verify that your home insurance policy covers solar panels and doesn't exclude improper installations. Inquire about the extent of coverage for solar panels, including potential damages and liability.
6. Follow safety protocols
Never disconnect DC wire connectors under load. Before performing any maintenance or adjustments, turn off the system and ensure no current flows through DC wires. Use insulated tools and wear appropriate safety gear to prevent electric shocks. Maintain a minimum 1.5cm gap between the roof and the micro-inverter bottom for proper airflow.
7. Fire Safety Precautions
Install fire-resistant materials around panels and ensure easy access to emergency services. Consider non-combustible roofing materials like clay or concrete tiles. These materials provide an extra layer of protection and can help lower insurance premiums.

Ukpanah warns,
"Improper solar panel installations can lead to severe risks like fires and electric shocks. Always hire certified professionals and avoid DIY solutions to ensure safety. Quality installation is as crucial as the panels themselves."
