Plug-in solar panels have the potential to save households money on electricity bills, with a payback period of around 5 years and potential lifetime savings of £1,100. The UK government's clean-energy measures include the introduction of plug-in solar panels, which can be easily installed on balconies and in gardens. If 3 million households adopt plug-in solar, it could generate 1.2 terawatt hours of energy, saving households over £330 million and reducing imported LNG. This technology not only benefits homeowners but also allows renters to participate in the clean energy transition and benefit from clean energy in their homes.
