The Electrical Safety Roundtable (ESR) has published new consumer guidance on buying, installing and using plug-in solar devices, making the point that picking a product off a supermarket shelf, a DIY store or an online retailer is only the starting point.
The guidance sets out the checks and precautions the ESR says are needed for these systems to be compliant, suitable for the property and installed correctly.
Compliance marking 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, with a statement supplied alongside it confirming compliance. The 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 the instructions provided and never modify the plug, cables, inverter, panels, connectors or any other supplied component.
Installation and cable routing
The ESR 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, as this can damage them, and poorly routed or secured cabling can create trip hazards as well as further risk of damage.
Before buying, 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 purchasing a device. People living in flats or apartments may additionally need approval from the building owner, and 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 that process.
Who the guidance is intended for
The ESR presents 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 point consumers towards clear, consistent information. Electricians can also pass it on to potential customers so they understand why checks by a qualified and competent person matter before installation.
Nick Hayler, chair of the Electrical Safety in the Home group, said the organisation supports innovation that can help households take up 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.
