The Electrical Safety Roundtable (ESR) has published new consumer guidance on buying, installing and using plug-in solar devices. The organisation said there is more to consider than simply picking up a device from a supermarket, DIY store or online retailer, and that the guidance sets out the checks and precautions needed to help make sure such systems are compliant, suitable and correctly installed.
Compliance 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, with a statement confirming that it complies. The labelling should identify the manufacturer, the model or serial number, and the voltage, frequency, current, rated power, IP rating and protection class.
Consumers are advised to buy from reputable suppliers and to follow all instructions supplied with the product. The ESR also warns against modifying the plug, cables, inverter, panels, connectors or any other supplied components.
Installation and cable routing
Ideally, the device should be connected to a nearby external socket-outlet that is suitably located and protected. Cables should not be trapped in doors or windows, because this can damage them. Poorly routed and secured cabling can create trip hazards and add to the risk of damage.
Checks before buying
The ESR strongly recommends that consumers find a qualified and competent electrician to carry out the necessary checks on their electrical system before a plug-in solar device is installed. Consumers should also contact their insurer before purchasing.
Households in flats or apartments may need approval from the building owner, while tenants must seek permission from their landlord. Where applicable, managing agents, planning authorities and other interested parties should be informed.
Once a device is installed, the Distribution Network Operator must be notified within 28 days. The instructions supplied with a compliant system should explain this process.
Supporting tenants, residents and customers
The guidance is intended as a resource for anyone advising 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 towards clear, consistent information, and electricians can share it with potential customers to explain why checks by a qualified and competent electrician matter 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 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. By making the guidance widely available, the ESR said it aims to help consumers benefit from plug-in solar while keeping safety the priority.
