The Electrical Safety Roundtable (ESR) has issued new consumer guidance on buying, installing and using plug-in solar devices. The organisation said the guidance is intended to help households make informed and safe choices and to explain the checks and precautions needed for a system to be compliant, suitable and correctly installed. It noted that buying a device from a supermarket, DIY store or online retailer involves more consideration than selecting a product.
According to the ESR, a compliant 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.
Product and installation checks
The guidance advises consumers to buy from reputable suppliers, follow all instructions and avoid modifying the plug, cables, inverter, panels, connectors or other supplied components. It says the device should ideally be connected to a nearby external socket-outlet that is suitably located and protected.
Cables should not be trapped in doors or windows because this can cause damage. Poorly routed or secured cabling can create trip hazards and increase the risk of damage, the ESR said.
Before purchase, the ESR strongly recommends finding a qualified and competent electrician to check the property's electrical system before a plug-in solar device is installed. Consumers should also contact their insurer before buying a device, the guidance says.
Permissions and notification
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 also be informed.
After installation, the Distribution Network Operator must be notified within 28 days. The instructions supplied with a compliant system should explain this process, according to the guidance.
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 possible permissions and safety checks. Organisations can use it to raise awareness and direct consumers to clear, consistent information, while electricians can share it with potential customers to explain why pre-installation checks matter.
Nick Hayler, chair of the Electrical Safety in the Home group, said the organisation supports innovation that helps households adopt renewable energy and reduce bills, but this must be done safely. He said consumers should follow the guidance and use a competent and qualified person to help ensure a plug-in solar device is suitable and correctly installed.
