The Electrical Safety Roundtable (ESR) has issued new consumer guidance on buying, installing and using plug-in solar devices. The organisation said consumers need to consider more than simply buying a device from a supermarket, DIY store or online retailer, and the guidance aims to encourage safety by explaining the checks and precautions needed for compliant, suitable and correctly installed systems.
According to the ESR, a compliant plug-in solar device should meet the Plug-in Solar Device Interim Product Specification and be clearly marked and accompanied by a statement confirming compliance. Product labelling should identify the manufacturer, model or serial number, voltage, frequency, current, rated power, IP rating and protection class.
Buying and installation checks
Consumers should buy from reputable suppliers, follow all instructions and never modify the plug, cables, inverter, panels, connectors or other supplied components. The ESR said the device should ideally be connected to a nearby, suitably located and protected external socket-outlet. Cables must not be trapped in doors or windows because this may damage them, and poorly routed or secured cabling can create trip hazards and further risk of damage.
Before purchasing a plug-in solar device, the ESR strongly recommends that consumers find a qualified and competent electrician to perform the necessary checks on their electrical system before installation. Consumers should also contact their insurer before buying a device.
Permissions and notification
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 instructions supplied with a compliant system should explain this process, according to the guidance.
Supporting consumers
The ESR described the guidance as a resource for anyone supporting consumers 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 signpost consumers to clear, consistent information. Electricians can also share it with potential customers to help them understand why checks by a qualified and competent electrician are important before installation.
Nick Hayler, Chair of the Electrical Safety in the Home group, said: “We support innovation that can help households embrace renewable energy and reduce their bills, but it has to be done safely. Consumers should follow the guidance and use a competent and qualified person to help ensure their 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 ensuring safety remains the priority.
