The Electrical Safety Roundtable (ESR) has published new consumer guidance on plug-in solar devices, aimed at helping households make informed and safe choices when buying, installing and using the equipment. The organisation said the guidance goes beyond the basic purchase decision, setting out the checks and precautions needed for a system to be compliant, suitable and correctly installed.
According to the ESR, a compliant plug-in solar device should meet the Plug-in Solar Device Interim Product Specification and be clearly marked with a statement confirming compliance. Product labelling should identify the manufacturer, model or serial number, voltage, frequency, current, rated power, IP rating and protection class. Consumers are advised to buy from reputable suppliers, follow all instructions and avoid modifying the plug, cables, inverter, panels, connectors or other supplied components.
Installation and electrical checks
The guidance recommends connecting the device to a nearby, suitably located and protected external socket-outlet. Cables should not be trapped in doors or windows because this can damage them, and poorly routed or secured cabling can create trip hazards and further risk of damage.
Before buying a plug-in solar device, the ESR strongly recommends that consumers find a qualified and competent electrician to check their electrical system. Consumers should also contact their insurer before purchasing. People living in flats or apartments may need approval from the building owner, while tenants must seek permission from their landlord. Managing agents, planning authorities and other interested parties should be informed where applicable.
After installation, the Distribution Network Operator must be notified within 28 days. The ESR said instructions supplied with a compliant system should explain this process.
Supporting households and advisers
The guidance is also intended as a resource for anyone supporting consumers who are considering plug-in solar. Letting agents and landlords can share it with tenants and residents to explain the permissions and safety checks that may be required. Organisations can use it to raise awareness and point consumers to clear, consistent information, while electricians can share it with potential customers to explain why checks by a qualified and competent electrician are important before installation.
Nick Hayler, chair of the Electrical Safety in the Home group, said the ESR supports innovation that can help households embrace renewable energy and reduce their bills, but that it must be done safely. He encouraged consumers to follow the guidance and use a competent and qualified person to help ensure a plug-in solar device is suitable and installed correctly.
By making the guidance widely available, the ESR said it aims to help consumers benefit from plug-in solar while keeping safety as the priority.
