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 that buying a device from a supermarket, DIY store or online retailer involves more to consider than the purchase itself, and that the guidance explains the checks and precautions needed to help ensure such systems are compliant, suitable and correctly installed.
According to the ESR, a compliant plug-in solar device should meet the Plug-in Solar Device Interim Product Specification and be clearly marked, accompanied by a statement confirming compliance. The product labelling should identify the manufacturer, the model or serial number, voltage, frequency, current, rated power, IP rating and protection class.
Consumers are advised to buy from reputable suppliers and to follow all supplied instructions. The guidance states that the plug, cables, inverter, panels, connectors and other supplied components should never be modified.
Installation and cable routing
Ideally, the device should be connected to a nearby external socket-outlet that is suitably located and protected. Cables must not be trapped in doors or windows, as this may damage them, and poorly routed or secured cabling can create trip hazards as well as further risk of damage.
Checks before purchase
The ESR strongly recommends that consumers find a qualified and competent electrician to carry out the necessary checks on their electrical system before installing plug-in solar. Consumers should also contact their insurer before buying a device. People living in flats or apartments may additionally 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.
After installation, the Distribution Network Operator must be notified within 28 days. The instructions supplied with a compliant system should explain this process.
A resource for advisers
The guidance is intended as a resource for anyone 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 signpost consumers to clear, consistent information, while electricians can share it with potential customers to help them understand why checks by a qualified and competent electrician are important before installation.
The ESR said that by making the guidance widely available it aims to help consumers benefit from plug-in solar while ensuring safety remains the priority.
Nick Hayler, Chair of the Electrical Safety in the Home group, said the organisation supports innovation that can help households embrace renewable energy and reduce their bills, but that it has to be done safely. He added that consumers should follow the guidance and use a competent and qualified person to help ensure their plug-in solar device is suitable and installed correctly.
