The Electrical Safety Roundtable (ESR) has issued new consumer guidance on buying, installing and using plug-in solar devices. The organisation said the advice is intended to help households make informed and safe choices, and to explain the checks and precautions needed for a system that is compliant, suitable and correctly installed.
Product compliance and labelling
The ESR said consumers should look beyond simply purchasing a device from a supermarket, DIY store or online retailer. 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. Its 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. 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 or secured cabling can create trip hazards and increase the risk of damage.
Installation and electrical checks
Before buying a plug-in solar device, the ESR strongly recommends that consumers find a qualified and competent electrician to carry out the necessary checks on their electrical system before installation. 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.
Permissions and notification
After installation, the Distribution Network Operator must be notified within 28 days. The instructions supplied with a compliant system should explain this process. The guidance is also presented 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.
Guidance for landlords, agents and electricians
Organisations can use the guidance to raise awareness and direct consumers to clear, consistent information. Electricians can share it with potential customers to help them understand why checks by a qualified and competent electrician are important before installation. The ESR said that making the guidance widely available is intended to help consumers benefit from plug-in solar while keeping safety as the priority.
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 must 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.
