The Electrical Safety Roundtable (ESR) has published new consumer guidance on buying, installing and using plug-in solar devices, warning that choosing a unit from a supermarket, DIY store or online retailer is only part of the process.
The guidance aims to encourage safety by explaining the checks and precautions needed to help ensure such systems are compliant, suitable and installed correctly.
Compliance and product 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, accompanied by a statement confirming compliance. The 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.
Installation, siting and cable routing
- Ideally, connect the device to a nearby, suitably located and protected external socket-outlet.
- Do not trap cables in doors or windows, as this may damage them.
- Poorly routed and secured cabling can create trip hazards and further risk of damage.
Checks before buying
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 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.
Notifying the network operator
After installation, the Distribution Network Operator must be notified within 28 days. The ESR says the instructions supplied with a compliant system should explain this process.
Who the guidance is for
The guidance is presented 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 explain why checks by a qualified and competent electrician matter before installation.
By making the guidance widely available, the ESR said it aims to help consumers benefit from plug-in solar while keeping safety the priority.
Nick Hayler, Chair of the Electrical Safety in the Home group, said the group 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.
