The Electrical Safety Roundtable (ESR) has launched new guidance 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 purchasing a device from a supermarket, DIY store or online retailer.
The guidance is intended to encourage safety by explaining the checks and precautions needed to help ensure these systems are compliant, suitable for the property and installed correctly.
Compliance marking and product 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, accompanied by a statement confirming compliance. The product labelling should identify:
- The manufacturer, plus the model or serial number
- Voltage, frequency and current
- Rated power
- IP rating and protection class
Buying and installing the device
Consumers are advised to buy from reputable suppliers and to follow all instructions. They should never modify the plug, cables, inverter, panels, connectors or other supplied components.
Ideally, the device should be connected to a nearby external socket-outlet that is suitably located and protected. Cables must not be trapped in doors or windows, as this may damage them. Poorly routed and secured cabling can create trip hazards and further risk of damage.
Checks to complete 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 a plug-in solar device. Buyers should also contact their insurer before purchasing.
Households in flats or apartments may additionally 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.
Notification after installation
Once installed, 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.
A resource for those advising consumers
The guidance is positioned 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: “We support innovation that can help households embrace renewable energy and reduce their bills, but it has to 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.”
By making the guidance widely available, the ESR said it aims to help consumers benefit from plug-in solar while ensuring safety remains the priority.
