GoKawiilUK legalizes plug-in solar, but IET warns home wiring often isn't ready
Britain's government has moved to permit plug-in solar kits, but the Institution of Engineering and Technology says the country's electrical infrastructure wasn't built for it. IET technical regulations head Mark Coles says many homes still use older Residual Current Devices designed only for one-way power flow, which can fail or burn out when solar feeds electricity back through them. The IET issued its own warning the same day as the government's announcement, urging homeowners to get professional wiring checks before installing any system.
GoKawiil's interpretation of the reporting above, not reported fact.
Unlike Germany, which built its plug-in solar success on decades-old two-pole wiring standards suited to two-way power flow, the UK's plug and socket infrastructure was never designed for this use case. That mismatch means a well-intentioned green energy policy could create real safety hazards, including fire and shock risks, if adopted before hardware and regulations catch up.
- The UK has legalized plug-in solar kits, mirroring policies popular in Germany.
- Experts warn many UK homes have outdated RCDs incompatible with two-way electrical flow from solar panels.
- The IET recommends professional wiring inspections before installing any plug-in solar system.
