Understanding solar panel risks for care homes

This article first appeared Care Markets 

The installation of solar panels is continuing to gain popularity across the UK, with over 1.5 million households now  having a solar pv system. b Solar power offers a dependable energy solution for businesses, providing them with a source of renewable electricity to help them reduce their energy costs.  

Beyond financial benefits, solar power provides care homes the opportunity to have greater energy independence, reducing vulnerability to fluctuating energy prices and supply chain disruptions. The transition to renewable energy also enhances the reputation of care facilities, showcasing their dedication to environmental stewardship and ethical operations. By adopting solar solutions, care homes create a more sustainable, reliable, and forward-thinking approach to energy consumption, benefiting both residents and the broader community. Additionally, investing in solar technology aligns with Environmental, Social, and Governance (ESG) principles, demonstrating a commitment to sustainability and responsible energy use. 

However, while solar panels offer significant benefits, they also introduce new risks and liabilities that care home operators should carefully consider. 

Regulatory overview 

Although the UK has legislation governing the solar industry, there is no unified, long-term strategy for its growth. Building regulations, such as Part L,require energy efficiency measures and encourage renewable energy installations, including solar panels. Despite this, responsibility for ensuring the quality of materials and the competence of installers lies with the property owner. This makes it vital to choose a reliable provider and ensure the system is suitable for your care home’s needs. 

Without a centralised strategy, navigating the complexities of solar panel installation can be challenging, especially for care home operators seeking dependable energy solutions. Thorough research into providers, warranties, and certifications is crucial to safeguard against subpar materials or inexperienced installers. Choosing a provider with a strong track record can ensure compliance with regulations and optimise system performance, ultimately enhancing energy efficiency. Additionally, government incentives, grants, and financing options can support the adoption of solar technology, reducing initial costs while promoting long-term sustainability.  

Risks and liabilities 

Solar panels, particularly roof-mounted systems, can impact a building’s fire dynamics. Improper installation, substandard materials, or system failures can increase fire risks. Below are common causes of solar panel fires: 

1. Electrical faults 

• Loose connections or poorly installed wiring can cause arcing and overheating. 

• Faulty DC isolators—used to disconnect the system—are frequent culprits of electrical fires. 

2. Manufacturing defects 

• Panels with defects like hot spots can overheat, potentially igniting nearby materials. 

3. Inverter malfunctions 

• Inverters, which convert DC electricity to AC, can fail if improperly installed or maintained, leading to overheating. 

4. Poor maintenance 

• Dirt, debris, or shading can cause localised overheating, increasing the risk of fire. 

5. Overvoltage or overloading 

• Systems not properly matched to the grid or building’s capacity may experience overvoltage issues. 

6. Rodent damage 

• Animals chewing on cables can expose wiring, creating short circuits and fire hazards. 

Roof-mounted systems are also vulnerable to extreme weather, including hail, lightning, high heat, and wind. These events can damage installations or make them unstable, regular roof inspections after severe weather are essential to identify damage and ensure the system remains secure. 

Maintenance is key 

A common misconception is that solar PV systems are maintenance-free, this is not the case, regular maintenance is critical to avoid accidents and ensure the system operates efficiently. Care providers should note that solar installations are electrical systems and must comply with regulations, such as BS 7671 Requirements for Electrical Installations.  Solar Energy UK   provides a best practice guide, recommending maintenance checks based on system capacity. While annual inspections may suffice for smaller systems, larger installations may require checks as frequently as every quarter, regular maintenance not only ensures safety but also fulfils your duty as a building owner to protect residents, staff, and visitors from harm. 

Notify Your insurer 

If you’ve installed roof-mounted solar panels at your care home, it is essential to inform your insurer or broker. This ensures your insurance policy is updated to cover any new risks associated with the system. 

Solar panels can be an asset to your care home, offering cost savings and environmental benefits. By understanding and managing the associated risks, you can protect your property, residents, and staff while reaping the rewards of renewable energy.
