The Electrical Safety Roundtable (ESR) has launched guidance intended to help consumers choose, install and use plug-in solar devices safely. The organisation said buyers need to consider more than selecting a product from a supermarket, DIY store or online retailer. The guidance explains the checks and precautions intended to help ensure that 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. It should also be clearly marked and supplied 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.
Purchase and installation checks
The guidance advises consumers to buy from reputable suppliers, follow all instructions and avoid modifying the plug, cables, inverter, panels, connectors or other supplied components. Ideally, the device should 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 may damage them. Poorly routed and secured cabling can create trip hazards and add further risk of damage, the ESR said.
Before buying a plug-in solar device, the ESR strongly recommends finding a qualified and competent electrician to carry out the necessary checks on the electrical system before installation. Consumers should also contact their insurer before purchasing, the guidance states.
Permissions and notification
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. 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.
Supporting consumers
The ESR describes the guidance 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. Electricians can also share it with potential customers to help them understand 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 organisation supports innovation that can help households embrace renewable energy and reduce their bills, but this has to be done safely. He said 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.
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.
