The Electrical Safety Roundtable (ESR) has published new consumer guidance on buying, installing and using plug-in solar devices, warning that choosing a product is only one part of the process.
The guidance is intended to help households check that a device is compliant, suitable for their property and installed correctly. It also sets out who consumers may need to consult before and after installation.
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 that it complies. 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 to follow the supplied instructions. The guidance says plugs, cables, inverters, panels, connectors and other supplied components should never be modified.
For connection, the ESR says the device should ideally be plugged into a nearby external socket-outlet that is suitably located and protected. Cables should 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: electrician and insurer
The ESR strongly recommends finding a qualified and competent electrician before purchasing a plug-in solar device. The electrician should carry out the necessary checks on the home's electrical system before installation.
Consumers should also contact their insurer before buying a device. Those 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.
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.
Support for consumers and advisers
The ESR says 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 the material to raise awareness and direct consumers to clear, consistent information. Electricians can also share it with potential customers to explain why checks by a qualified and competent professional are important before installation.
Nick Hayler, Chair of the Electrical Safety in the Home group, said the ESR supports innovation that can help households embrace renewable energy and reduce their bills, but that it must be done safely. 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, he said.
By making the guidance widely available, the ESR aims to help consumers gain the benefits of plug-in solar while keeping safety as the priority.
