The Electrical Safety Roundtable (ESR) has published new guidance for consumers who buy, install or use 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 help make a system compliant, suitable and correctly installed.
According to the guidance, a compliant 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 the supplied instructions and avoid modifying the plug, cables, inverter, panels, connectors or other components.
Installation and notification
The ESR says the device should ideally 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, and poorly routed or secured cabling can create trip hazards and further risk of damage.
Before buying a device, consumers are strongly encouraged to find a qualified and competent electrician to check their electrical system ahead of installation. The ESR 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 instructions supplied with a compliant system should explain this process, according to the guidance.
Resource for landlords and electricians
The ESR says the guidance can support anyone advising consumers on plug-in solar. Letting agents and landlords can share it with tenants and residents to explain 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 person matter before installation.
Nick Hayler, chair of the Electrical Safety in the Home group, said the ESR supports innovation that helps households adopt renewable energy and reduce bills, but this must be done safely. He said consumers should follow the guidance and use a competent, qualified person to help ensure their plug-in solar device is suitable and installed correctly.
