Nissan is investing £10 million ($13.5 million) in a pioneering UK research programme that could change how electric vehicles are powered. If successful, future EVs may generate part of their own electricity from sunlight, helping drivers reduce charging costs, increase driving range and rely less on public charging stations.
The three-year initiative, known as Project SUITE (Smart Use of Integrated Technology for EVs), is backed by the UK Government through its DRIVE35 programme. It brings together leading technology companies and research partners to develop vehicles capable of producing, managing and sharing energy more intelligently.
The project combines three emerging technologies: high-efficiency solar panels integrated into vehicle bodies, artificial intelligence to optimise charging decisions, and vehicle-to-grid (V2G) technology that allows electric vehicles to return electricity to the national grid when demand is high.
At the heart of the programme is the development of perovskite-on-silicon tandem solar cells, created by UK-based Oxford PV. These next-generation solar cells are significantly more efficient than traditional silicon panels, making them suitable for the limited surface area available on a vehicle’s roof, bonnet and bodywork.
The challenge for engineers has always been simple: a car offers far less space for solar panels than a rooftop. Every percentage increase in solar efficiency therefore becomes critical. Higher-performing panels could generate enough electricity during daylight hours to meaningfully support everyday driving.
For many motorists, the biggest benefit would be lower running costs. Even modest amounts of solar-generated electricity could reduce the number of charging sessions required each week, particularly for drivers making short daily commutes or local journeys.
Electric vehicles already cost less to operate than petrol or diesel cars in many markets because electricity is generally cheaper than fuel. They also require less routine maintenance, with fewer moving parts and no engine oil changes. Solar charging could strengthen those financial advantages even further.
Artificial intelligence is expected to play an equally important role. Instead of simply charging whenever a vehicle is plugged in, AI could identify the cheapest electricity tariffs, prioritise renewable energy when available and decide whether the vehicle should store electricity or sell it back to the grid.
Vehicle-to-grid technology could also transform EVs into mobile energy storage units. Since private cars remain parked for around 95% of their lifetime, their batteries could provide valuable electricity during periods of peak demand before being recharged later when energy prices fall.
The project reflects a broader shift in the automotive industry. Manufacturers are increasingly viewing electric vehicles as part of a connected energy ecosystem rather than standalone means of transport. Future EVs could work seamlessly with home solar systems, smart chargers and household energy management platforms.
Public reaction has been largely positive. Many EV enthusiasts believe integrated solar technology represents a logical next step in electric mobility.
Some motorists remain cautious, arguing that vehicle-mounted solar panels currently provide only limited additional driving range. Critics also point to the extra cost of integrating solar technology into production vehicles.
However, supporters argue that advances in solar efficiency, battery technology and artificial intelligence could significantly improve the value of integrated solar systems over the coming years.
