The Electrical Safety Roundtable (ESR) has published new consumer guidance on buying, installing and using plug-in solar devices, saying that choosing a product from a supermarket, DIY store or online retailer is only one part of the process.
The guidance explains the checks and precautions needed to help ensure that plug-in solar systems are compliant, suitable and correctly installed. It is intended for consumers and for organisations that support them, including letting agents, landlords and electricians.
Product compliance and labelling
According to the ESR, a compliant plug-in solar device should meet the Plug-in Solar Device Interim Product Specification and be clearly marked and accompanied by a statement confirming compliance. The 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.
Installation and cable safety
The guidance says the device should ideally be connected to a nearby, suitably located and protected external socket-outlet. Cables must not be trapped in doors or windows because this may damage them. Poorly routed and secured cabling can create trip hazards and further risk of damage.
Before buying a plug-in solar 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.
Permissions and notifications
Consumers should also contact their insurer before purchasing a device. 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.
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 says the guidance provides 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 direct consumers to clear, consistent information. Electricians can also 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 ESR supports innovation that can help households embrace renewable energy and reduce their bills, but that it 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.
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.
