The Electrical Safety Roundtable (ESR) has published new consumer guidance on plug-in solar devices, aimed at helping households make safe and informed decisions when buying, installing and using the equipment.
The organisation said consumers need to consider more than the act of purchasing a device from a supermarket, DIY store or online retailer. The guidance sets out checks and precautions intended to help ensure that systems are compliant, suitable and correctly installed.
Product and installation checks
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 all 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 external socket-outlet that is suitably located and protected.
The guidance also warns that cables must 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, it adds.
Before purchase, the ESR strongly recommends that consumers find a qualified and competent electrician to check their electrical system ahead of installation. Consumers should also contact their insurer before buying a device.
Permissions and notification
For people living in flats or apartments, approval from the building owner may be required. Tenants must seek permission from their landlord. Where applicable, managing agents, planning authorities and other interested parties should be informed.
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 needed. Organisations can use it to raise awareness and point consumers to clear, consistent information, while electricians can share it with potential customers to explain why checks by a qualified and competent electrician are important before installation.
Nick Hayler, chair of the Electrical Safety in the Home group, said the group supports innovation that can help households embrace renewable energy and reduce their bills, but this must be done safely. He urged consumers to follow the guidance and use a competent and qualified person to help ensure their plug-in solar device is suitable and correctly installed.
By making the guidance widely available, the ESR said it aims to help consumers benefit from plug-in solar while keeping safety as the priority.
