The Electrical Safety Roundtable (ESR) has published new consumer guidance on buying, installing and using plug-in solar devices, warning that picking a product from a supermarket, DIY store or online retailer is only the starting point.
The guidance aims to encourage safe practice by explaining the checks and precautions needed to help ensure such systems are compliant, suitable for the property and installed correctly.
Product marking and compliance
According to the ESR, a compliant plug-in solar device should meet the Plug-in Solar Device Interim Product Specification, be clearly marked, and come with a statement confirming compliance.
Product labelling should identify the manufacturer and the model or serial number, and state voltage, frequency, current, rated power, IP rating and protection class. Consumers are advised to buy from reputable suppliers, follow all supplied instructions, and never modify the plug, cables, inverter, panels, connectors or other supplied components.
Installation and cable routing
Ideally, the ESR says, 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 because this may damage them, and poorly routed or secured cabling can create trip hazards as well as further risk of damage.
Before buying, 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 and notification
Consumers should also contact their insurer before purchasing a device. People living in flats or apartments may need approval from the building owner, tenants must seek permission from their landlord, and 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.
Who the guidance is for
The ESR presents the guidance 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 direct consumers to clear, consistent information, while electricians can share it with potential customers to help them understand why checks by a qualified and competent electrician matter before installation.
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.
By making the guidance widely available, the ESR said it aims to help consumers benefit from plug-in solar while keeping safety the priority.
