The Electrical Safety Roundtable (ESR) has published new guidance intended to help consumers make informed and safe choices when buying, installing and using plug-in solar devices. The organisation said there is more to consider than simply buying a device from a supermarket, DIY store or online retailer, and that the guidance explains the checks and precautions needed to help ensure such systems are compliant, suitable and installed correctly.
The document addresses devices sold through retail channels, which the ESR says require consumers to look beyond the purchase itself to the condition of the electrical system they will connect to and the permissions that may apply.
Compliance marking and product labelling
According to the ESR, a compliant plug-in solar device should meet the Plug-in Solar Device Interim Product Specification and be clearly marked, accompanied by a statement confirming compliance. Product labelling should identify the manufacturer, the model or serial number, voltage, frequency, current, rated power, IP rating and protection class.
Consumers are advised to buy from reputable suppliers and to follow all supplied instructions. The ESR also states that the plug, cables, inverter, panels, connectors and other supplied components should never be modified.
Installation and cable routing
Ideally, the device should be connected to a nearby external socket-outlet that is suitably located and protected. Cables must not be trapped in doors or windows, as this may damage them, and poorly routed or secured cabling can create trip hazards as well as further risk of damage.
Before purchasing a device, the ESR strongly recommends that consumers find a qualified and competent electrician to carry out the necessary checks on their electrical system ahead of installation.
Permissions, insurance and notification
The guidance also covers administrative steps. Consumers should contact their insurer before buying a device. 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.
Who the guidance is for
The ESR describes the document 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 signpost consumers to clear, consistent information, and electricians can share it with potential customers to help them understand why checks by a qualified and competent electrician matter before installation.
Safety alongside savings
Nick Hayler, Chair of the Electrical Safety in the Home group, said the organisation supports innovation that can help households embrace renewable energy and reduce their bills, but that it has to be done safely. He said 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.
The ESR said that by making the guidance widely available it aims to help consumers benefit from plug-in solar while ensuring safety remains the priority.
