Plug-in solar panels are expected to go on sale in UK supermarkets within months, priced at around £500. Lidl and Iceland are working with the government to offer the kits, which can be mounted on balconies or in gardens and connected to a home via a standard plug. However, several regulatory and practical obstacles must be addressed before the systems become widely accessible.
The panels, capable of generating 200–500kWh per year (roughly 10% of a typical household's energy use), will be limited to 800W under new safety standards. These include 'anti-islanding' measures to prevent live prongs after unplugging or grid failure. The government is amending regulations to allow plug-in connections, provided kits meet updated safety requirements.
Despite the promise, challenges remain. Tenants may need landlord permission due to building insurance implications, and planning restrictions could affect those in conservation areas or requiring optimal panel tilting, which can boost performance by 30–45%. Older UK electrical systems may also struggle with the feed-in setup, prompting concerns from the Institute of Engineering and Technology and the Electrical Contractors Association about cheap imports and lack of industry standards.
Householders must notify their district network operator and submit a G98 notification to their electricity supplier. While some may install the system themselves, experts suggest hiring an electrician, which could make direct wiring more practical. Users should also check insurance policies and consider shading or north-facing balconies that limit output.
To maximise savings, homeowners are advised to use generated power directly, as export tariffs are lower than import prices. Battery storage could help, but adds cost. The government has not yet clarified whether planning laws will be updated to accommodate tilting panels or balcony installations.
