The Electrical Safety Roundtable (ESR) has published new consumer guidance covering the purchase, installation and use of plug-in solar devices, warning that buying a kit from a supermarket, DIY store or online retailer is only the starting point.
The organisation said the guidance is intended to encourage safety by explaining the checks and precautions needed to help ensure such 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, accompanied by a statement confirming compliance.
Product labelling should identify the manufacturer, the model or serial number, voltage, frequency, current, rated power, IP rating and protection class. Consumers are advised to buy from reputable suppliers, follow all supplied instructions and never modify the plug, cables, inverter, panels, connectors or other supplied components.
Installation and cable routing
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 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
Consumers should also contact their insurer before buying 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 ESR said the instructions supplied with a compliant system should explain this process.
Who the guidance is 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, while 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: “We support innovation that can help households embrace renewable energy and reduce their bills, but it 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.”
