The Electrical Safety Roundtable (ESR) has published new consumer guidance on buying, installing and using plug-in solar devices, warning that choosing a product from a supermarket, DIY store or online retailer is only one part of the process.
The guidance sets out the checks and precautions intended to help households ensure that a plug-in solar system is compliant, suitable for the property and installed correctly. Its central message is that safety should be considered before purchase, not only after a device has been connected.
Product compliance and labeling
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. The product labeling 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 any other supplied components.
Installation and cable routing
The guidance says the device should ideally 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 can damage them. Poorly routed or secured cabling can also create trip hazards and increase the risk of damage.
Before buying a plug-in solar device, the ESR strongly recommends that consumers find a qualified and competent electrician to check their electrical system. The organization also advises consumers to contact their insurer before purchase. 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 after installation
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.
The ESR says the guidance is 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. Organizations can use it to raise awareness and direct consumers to clear, consistent information, while electricians can 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 must 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.
