The Electrical Safety Roundtable (ESR) has published new consumer guidance on buying, installing and using plug-in solar devices, aimed at helping households make informed and safe choices.
The organisation said the guidance goes further than the decision to buy a device from a supermarket, DIY store or online retailer, setting out the checks and precautions needed for a system to be compliant, suitable and correctly installed.
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 carry clear marking together with a statement confirming compliance.
Labels should identify the manufacturer, model or serial number, as well as voltage, frequency, current, rated power, IP rating and protection class. Consumers are advised to buy from reputable suppliers, follow the supplied instructions, and never modify the plug, cables, inverter, panels, connectors or other components provided.
Installation and cable routing
The guidance recommends connecting the device to a nearby external socket-outlet that is suitably located and protected. Cables should not be trapped in doors or windows, as this may damage them, and poorly routed or secured cabling can create trip hazards and further risk of damage.
Checks before purchase
The ESR strongly recommends that consumers find a qualified and competent electrician to carry out the necessary checks on their electrical system before a plug-in solar device is installed. Buyers should also contact their insurer before purchasing.
Additional permissions may apply depending on circumstances:
- People living in flats or apartments may need approval from the building owner.
- 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 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.
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 matter before installation.
Nick Hayler, Chair of the Electrical Safety in the Home group, said the organisation supports innovation that helps 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.
