The Electrical Safety Roundtable (ESR) has published new consumer guidance for people buying, installing and using plug-in solar devices. The organisation said the guidance is intended to help households make informed and safe choices, and to show that choosing a product from a shop or online retailer is only one part of the process.
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 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 the supplied instructions and avoid modifying the plug, cables, inverter, panels, connectors or other supplied components. The ESR said the device should ideally be connected to a nearby, suitably located and protected external socket-outlet. Cables should not be trapped in doors or windows because this can damage them, while 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 ask a qualified and competent electrician to carry out the necessary checks on their electrical system ahead of installation. Consumers should also contact their insurer before purchasing. People living in flats or apartments may need approval from the building owner, and 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 intended 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 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 explain why checks by a qualified and competent electrician matter before installation.
By making the guidance widely available, the ESR aims to help consumers gain the benefits of plug-in solar while keeping safety as the priority.
Nick Hayler, Chair of the Electrical Safety in the Home group, said the group supports innovation that can help households adopt renewable energy and reduce their bills, but that it must be done safely. He advised consumers to follow the guidance and use a competent and qualified person to help ensure their plug-in solar device is suitable and installed correctly.
