The Electrical Safety Roundtable (ESR) has published new guidance intended to help consumers choose, install and use plug-in solar devices safely. The organisation said buyers need to consider more than the initial purchase from a supermarket, DIY store or online retailer, and that the guidance explains the checks and precautions needed for a compliant, suitable and correctly installed system.
According to the ESR, a compliant device should meet the Plug-in Solar Device Interim Product Specification and carry clear marking and a statement confirming compliance. Product 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. The guidance also addresses cable routing: ideally, the device should be connected to a nearby, suitably located and protected external socket-outlet, and cables should not be trapped in doors or windows. Poorly routed or secured cabling can create trip hazards and increase the risk of damage.
Before buying a device, the ESR strongly recommends that consumers find a qualified and competent electrician to check their electrical system. It also advises contacting their insurer before purchase. People 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 ESR said instructions supplied with a compliant system should explain this process.
The guidance is also positioned as a resource for people supporting consumers who are considering plug-in solar. Letting agents and landlords can share it with tenants and residents to explain possible permissions and safety checks. Organisations can use it to raise awareness and direct consumers to clear, consistent information, while 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 adopt renewable energy and reduce bills, but that this must be done safely. He advised consumers to follow the guidance and use a competent and qualified person to help ensure a plug-in solar device is suitable and installed correctly.
By making the guidance widely available, the ESR said it aims to help consumers gain the benefits of plug-in solar while keeping safety as the priority.
