An electric car that charges itself from the sun and somehow shrinks your electricity bill? Sounds like a marketing fairy tale — but Nissan has just set out to make it real. The Japanese carmaker is leading a British research project called SUITE, which aims to answer the million-pound question: can EV charging actually be made cheap thanks to built-in solar panels, bidirectional V2G charging and smarter power electronics? The programme has a budget of £10 million, or roughly $13.3 million.
Project SUITE stands for Smart Use of Integrated Technology for EVs. It runs for three years and is backed by the UK government’s £4 billion DRIVE35 fund — serious money, and the expectations on Nissan will be just as serious. The work is being carried out by Nissan Technical Centre Europe in Cranfield together with ten industrial and academic partners.
And here’s where it gets interesting. The project isn’t built around one single feature but a stack of technologies, each of which already sounds futuristic on its own. A gallium nitride traction inverter with AI control. A bidirectional charging unit for V2G connection. Tandem solar panels integrated into the body. An intelligent charging management system. All of it — in one car.
The test car is the Nissan Leaf — a predictable choice, the veteran of the EV revolution back in service. The practical point of V2G is that the car can not only draw energy from the grid but also send it back — for example during peak demand hours or to support the home. Combined with solar top-up, this could meaningfully cut the owner’s costs, especially with time-of-use tariffs. But the final benefit will depend on local rules, electricity prices, home-charging access and battery life. So there’s no universal answer yet — just a hypothesis SUITE will be testing.
David Moss, Senior Vice President for R&D at Nissan in the AMIEO region, put it carefully but pointedly: “This project highlights the power of British innovation and marks a significant step towards the next generation of integrated energy technologies for electric vehicles”. According to him, working with industrial and academic partners should advance solutions that lower ownership costs, improve efficiency and deliver more value to customers.
Moss specifically named enhanced V2G, high-performance inverters and solar charging as part of a smarter and more resilient energy ecosystem. Translated from corporate-speak: Nissan is using the Leaf to pre-test what could end up in future production EVs. And if it works — the competition will have some catching up to do.
But honestly, the buyer doesn’t care about the V2G acronym or gallium nitride. The buyer cares about something much simpler: can this car depend less on expensive charging and at least partly act as a household energy buffer? If SUITE delivers, the EV stops being just a vehicle with a battery. It becomes part of your electricity bill — the part that can make it smaller.
