The Electrical Safety Roundtable (ESR) has published new guidance intended to help consumers make informed and safe choices when buying, installing and using plug-in solar devices.
The organisation said there is more to consider than simply buying a device from a supermarket, DIY store or online retailer. The guidance aims to encourage safety by explaining the checks and precautions needed to help ensure these systems are compliant, suitable and installed correctly.
Compliance marking 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, with a statement confirming compliance supplied alongside it.
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, follow all instructions, and never modify the plug, cables, inverter, panels, connectors or other supplied components.
Installation and cable routing
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, as this may damage them, and poorly routed or secured cabling can create trip hazards and further risk of damage.
Checks before purchase
The ESR strongly recommends that consumers find a qualified and competent electrician to perform the necessary checks on their electrical system before installing plug-in solar. Consumers should also contact their insurer before buying a device.
- People living in flats or apartments may also need approval from the building owner.
- Tenants must seek permission from their landlord.
- Managing agents, planning authorities and other interested parties should be informed where applicable.
Notifying the network operator
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.
A resource for those advising consumers
The guidance is presented 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.
Organisations can use it to raise awareness and signpost consumers to clear, consistent information, while electricians can share it with potential customers to help them understand 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 organisation supports innovation that can help households embrace renewable energy and reduce their bills, but that it has to 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.
