The Electrical Safety Roundtable (ESR) has issued consumer guidance on buying, installing and using plug-in solar devices, saying that choosing such a product involves more than picking one up from a supermarket, DIY store or online retailer.
The guidance sets out the checks and precautions needed to help ensure a system is compliant, suitable and correctly installed.
Product and installation checks
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. Its labelling 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 and follow all instructions. They should not modify the plug, cables, inverter, panels, connectors or any other supplied components.
The device should ideally be connected to a nearby, suitably located and protected external socket-outlet. 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 device, the ESR strongly recommends finding a qualified and competent electrician to carry out the necessary checks on the home’s electrical system before installation.
Permissions and notification
Consumers should also 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 a device is installed, the Distribution Network Operator must be notified within 28 days. The instructions supplied with a compliant system should explain this process.
The ESR says the guidance can support anyone advising 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, while electricians can share it with potential customers to show why checks by a qualified and competent person are important before installation.
Nick Hayler, chair of the Electrical Safety in the Home group, said the group supports innovation that can help households adopt renewable energy and reduce their bills, but that this must be done safely. He advised consumers to follow the guidance and use a competent and qualified person to help ensure a plug-in solar device is suitable and installed correctly.
The ESR said that by making the guidance widely available, it aims to help consumers benefit from plug-in solar while keeping safety as the priority.
