IET Urges Households to Check Electrical Safety Before Using Plug In Solar Products
The Institution of Engineering and Technology (IET) has issued an important warning to households considering the use of emerging plug in solar products, urging consumers to ensure their home electrical systems are safe before installation. The guidance comes as the UK Government moves towards allowing plug in solar technology to become more widely available to homeowners and renters across the country.
Plug in solar systems, already popular across parts of Europe including Germany, are designed to allow users to generate electricity from compact solar panels connected directly into domestic electrical systems. While the technology could help reduce energy bills and improve access to renewable energy, the IET has stressed that these systems are not comparable to ordinary household appliances.
According to the IET, many UK homes contain ageing electrical installations, outdated consumer units, or older protective devices that may not have been designed to handle electricity flowing back into circuits from generation equipment. This could potentially affect the operation of key safety devices such as Residual Current Devices (RCDs), which are intended to protect users from electric shock and electrical faults.
The organisation has highlighted concerns around:
Older RCDs not operating correctly with bidirectional current flow
Potential overheating risks in older wiring systems
The interaction of multiple plug in solar units during fault conditions
Electrical safety in properties that have not been recently inspected or maintained
The Government has confirmed that it is working with industry bodies, manufacturers and regulators to develop updated standards and regulations that would allow plug in solar products to be introduced safely into the UK market. Retailers and manufacturers are already preparing for potential rollout later this year.
For electricians and those entering the industry, the growing discussion around domestic renewable technologies highlights the increasing importance of electrical safety knowledge, inspection and testing skills, and understanding of current wiring regulations. As technologies evolve, ensuring installations remain compliant with the latest edition of BS 7671 and industry guidance will continue to play a critical role in maintaining safe electrical systems.
At OPTIMA Electrical Training, we support learners in developing the practical and theoretical skills needed to work safely within modern electrical environments, including inspection and testing, wiring regulations, and emerging technologies shaping the future of the industry.
