The Electrical Safety Roundtable (ESR) has issued new consumer guidance on plug-in solar devices, setting out the checks and precautions needed before such a system is bought, fitted and used. The organisation said households need to consider more than simply picking up a device from a supermarket, DIY store or online retailer, and that the guidance is intended to show how compliance, suitability and correct installation can be verified.
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, with a statement accompanying it 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 any other supplied components.
Installation and cable routing
Ideally 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, since this can damage them, and poorly routed or secured cabling can create trip hazards and 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
The guidance also covers the approvals that may be needed. Consumers should contact their insurer before purchasing 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.
Once installed, the Distribution Network Operator must be notified within 28 days. The instructions supplied with a compliant system should explain how this is done.
Who the guidance is for
Beyond individual buyers, 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, and organisations can use it to raise awareness and point consumers towards clear, consistent information. Electricians can also pass it to 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 take up renewable energy and reduce their bills, but that this has to be done safely. He advised consumers to follow the guidance and to use a competent and qualified person to help ensure their plug-in solar device is suitable and installed correctly.
By making the guidance widely available, the ESR said it aims to help consumers benefit from plug-in solar while keeping safety the priority.
