The Electrical Safety Roundtable (ESR) has published new consumer guidance intended to help households choose, install and use plug-in solar devices safely. The organisation said that buying a unit from a supermarket, DIY store or online retailer involves more to consider than the purchase itself, and that the guidance explains the checks and precautions needed to keep a system compliant, suitable and correctly installed.
According to the guidance, a compliant plug-in solar device should meet the Plug-in Solar Device Interim Product Specification and be clearly marked, with a statement confirming that it complies. The labelling should identify the manufacturer, the model or serial number, the voltage, frequency, current, rated power, IP rating and protection class.
Consumers are advised to buy from reputable suppliers, to follow all supplied instructions and never to modify the plug, cables, inverter, panels, connectors or any other component provided with the system.
Installation and cable routing
Where possible, 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, as this may damage them, and poorly routed or secured cabling can create trip hazards along with a further risk of damage.
Checks before buying
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.
Households in flats or apartments may additionally 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
Once a system is in place, the Distribution Network Operator must be notified within 28 days. The instructions supplied with a compliant system should explain this process.
The guidance is positioned 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 towards clear, consistent information. Electricians can also pass it 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 adopt renewable energy and reduce their bills, but that this must be done safely. He said consumers should follow the guidance and use a competent and qualified person to help ensure their device is suitable and correctly installed.
By making the guidance widely available, the ESR said it aims to help consumers gain the benefits of plug-in solar while keeping safety the priority.
