The Electrical Safety Roundtable (ESR) has published new consumer guidance for buying, installing and using plug-in solar devices. The organisation said the advice is intended to help households make informed and safe choices, and to show that selecting a product from a supermarket, DIY store or online retailer involves more than a simple purchase.
The guidance explains the checks and precautions needed to help ensure that a plug-in solar system is compliant, suitable and installed correctly. It is aimed at consumers and at those supporting them, including landlords, letting agents, electricians and other organisations.
Product compliance and 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 and accompanied by a statement confirming compliance. Product 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 to follow all instructions. The guidance says plugs, cables, inverters, panels, connectors and other supplied components should never be modified.
Installation and household checks
Ideally, the device should be connected to a nearby, suitably located and protected external socket-outlet. Cables must not be trapped in doors or windows because this may damage them. Poorly routed and secured cabling can create trip hazards and further risk of damage.
Before purchasing a plug-in solar device, the ESR strongly recommends that consumers find a qualified and competent electrician to perform the necessary checks on their electrical system before installation. Consumers should also contact their insurer before buying a device.
People living in flats or apartments may need approval from the building owner, while tenants must seek permission from their landlord. Where applicable, managing agents, planning authorities and other interested parties should be informed.
Notification and use of the guidance
After installation, the Distribution Network Operator must be notified within 28 days. The instructions supplied with a compliant system should explain this process.
The ESR said the guidance can be used by 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 signpost consumers to clear, consistent information, while electricians can share it with potential customers to explain why checks by a qualified and competent electrician are important before installation.
Nick Hayler, chair of the Electrical Safety in the Home group, said the group supports innovation that can help households embrace renewable energy and reduce their bills, but it must 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.
The ESR said that making the guidance widely available is intended to help consumers benefit from plug-in solar while keeping safety as the priority.
