The Electrical Safety Roundtable (ESR) has issued new consumer guidance on buying, installing and using plug-in solar devices. The organisation says choosing a product from a supermarket, DIY store or online retailer is only part of the process; consumers also need to understand the checks and precautions that make a system compliant, suitable and correctly installed.
Product compliance and labelling
According to the guidance, a compliant plug-in solar device should meet the Plug-in Solar Device Interim Product Specification and carry clear marking plus 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 supplied instructions and avoid modifying the plug, cables, inverter, panels, connectors or any other supplied components.
Installation and cable safety
The ESR says the device should ideally 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 can damage them. Poorly routed or secured cabling can also create trip hazards and increase the risk of damage.
Before buying a device, the ESR strongly recommends finding a qualified and competent electrician to check the household electrical system. Those checks should take place before the plug-in solar equipment is installed.
Insurance, 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, while tenants must seek permission from their landlord. Where applicable, managing agents, planning authorities and other interested parties should be informed.
Once a system has been installed, the Distribution Network Operator must be notified within 28 days. The instructions supplied with a compliant system should explain how this notification is handled.
Supporting consumers and sharing the advice
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 the material to raise awareness and direct consumers to clear, consistent information. Electricians can also share it with potential customers so they understand 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 this must be done safely. He said consumers should follow the guidance and use a competent, qualified person to help ensure their device is suitable and installed correctly.
