The Electrical Safety Roundtable (ESR) has launched guidance intended to help consumers make informed and safe choices when buying, installing and using plug-in solar devices. The organisation says that purchasing a unit from a supermarket, DIY store or online retailer involves more than choosing a product, and the guidance explains the checks and precautions needed to support compliance, suitability and correct installation.
Product and installation checks
According to the guidance, 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. 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 instructions and never modify the plug, cables, inverter, panels, connectors or other supplied components. Ideally, the device should be connected to a nearby, suitably located and protected external socket-outlet. Cables must not be trapped in doors or windows, as this may damage them. Poorly routed and secured cabling can create trip hazards and further risk of damage.
Before purchasing a device, the ESR strongly recommends that consumers find a qualified and competent electrician to carry out the necessary checks on their electrical system before installation. Consumers should also contact their insurer before buying. People living 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.
Notification and permissions
After installation, the Distribution Network Operator must be notified within 28 days. The instructions supplied with a compliant system should explain this process, the guidance states.
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.
Safety priority
Nick Hayler, Chair of the Electrical Safety in the Home group, said the ESR supports innovation that can help households embrace renewable energy and reduce their bills, but this has to be done safely. 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 aims to help consumers benefit from plug-in solar while ensuring that safety remains the priority.
