The Electrical Safety Roundtable (ESR) has published new guidance for consumers on buying, installing and using plug-in solar devices, warning that choosing a unit from a supermarket, DIY store or online retailer is only the first consideration.
The guidance aims to encourage safety by explaining the checks and precautions needed to help ensure these systems are compliant, suitable for the property and installed correctly.
What a compliant device should show
According to the ESR, 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 supplied alongside it.
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 never modify the plug, cables, inverter, panels, connectors or other supplied components.
Siting 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 because this may damage them, and poorly routed or secured cabling can create trip hazards as well as further risk of damage.
Before purchasing, the ESR strongly recommends that consumers find a qualified and competent electrician to carry out the necessary checks on their electrical system ahead of installation.
Permissions and notification
The guidance also sets out approvals and notices that may apply around an installation:
- Consumers should contact their insurer before purchasing a device.
- People living in flats or apartments may also 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.
Who the guidance is intended for
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, and organisations can use it to raise awareness and point consumers to clear, consistent information. Electricians can also pass it on to potential customers to help them understand why checks by a qualified and competent electrician matter 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.
By making the guidance widely available, the ESR says it aims to help consumers benefit from plug-in solar while keeping safety the priority.
