Brits can start plugging in their own solar NOW as Octopus Energy becomes the first major energy supplier to roll out the tech following new rules coming into force.
The new plug-in system lets households generate their own electricity without installing traditional rooftop panels – meaning renters, flat-dwellers and people without a suitable roof can now get in on the solar boom and cut their bills.
Made to suit different homes and budgets, Octopus’ plug-in solar kits start at £450, with customers able to choose between a one or two-panel setup.
The company estimates households could save up to £150, depending on factors including sunlight levels and household energy use.*
For households opting for two panels, pairing the system with a smart export tariff could mean paying back the cost of the panels in just five and a half years.
The 460W panels can be wall- or floor-mounted and are designed to capture sunlight from both sides, and customers can track their generated electricity via the Octopus app.
The kit comes with a standard three-pin plug and a 5m cable, making it easy to slot in at home and help power up everyday appliances such as fridges, washing machines or TVs.
The system is designed for simple DIY installation, meaning customers can easily set it up themselves in just an hour and even take it with them if they decide to move.
Octopus will also add plug-in solar panels to its ownNook Cube plug-in battery offering, launching early next year for households in the UK, Germany, France, Italy and Spain.
According to government data released today, residential solar is surging to record highs across all UK regions – with nearly 172,000 installations completed since the start of 2026.**
Rebecca Dibb-Simkin, Chief Product and Marketing Officer at Octopus, said: “Britons love solar – generate your own green power, slash bills, AND get energy independent, what’s not to love.
“But you shouldn’t need a roof to tap into the savings. Plug-in solar democratises cheaper energy, making sure everyone can shrink their bill while helping build a greener grid.”
Customers can order their panels via the Octopus website now.
