Renault 4 E-Tech electric 'Plein Sud' completes solar-powered Land's End to John O'Groats DriveA Renault 4 E-Tech electric ‘Plein Sud’ has completed the Easee Sun Run, a 1,000-mile journey from Land’s End to John O’Groats powered only by solar energy – but more than a test of endurance, the drive became a route defined by discovery.

Timed around the summer solstice, the journey set out to follow the sun the length of Britain. What it found along the way was something more compelling: a country already putting solar energy to work in ways that are practical, inventive and, at times, remarkable.

Early in the route, solar power was already doing plenty of heavy lifting. At Roskilly’s Ice Cream in Cornwall, solar panels are helping power a hard-working business day in, day out, while at Chard Junction – where the Renault 4 E-Tech electric recharged for the first time since leaving Land’s End – the UK’s oldest commercial solar farm continues to generate clean energy on an impressive scale. As the Renault 4 E-Tech electric reached Derbyshire, Whaley Bridge Cricket Club was showing a different side of the same story, using solar to run fully off grid, keeping the lights on and the pavilion going without relying on the grid at all.

At Swansea University, Power Roll is developing rollable solar films – lightweight, flexible and designed to bring photovoltaic technology to surfaces and spaces that traditional panels can’t reach. In Durham, researchers are pushing things further still, working on ultra-efficient vehicles capable of running directly on energy from the sun, turning solar power from something stored into something immediate.

By the time the Renault 4 E-Tech electric reached Scotland, solar had taken on yet another form. A striking solar pyramid south of Edinburgh stood as a reminder of how far the technology has come, while on the east coast, off-grid homes and businesses are already using solar generation and battery storage to live and work independently of traditional infrastructure.

Threading all of this together was an electric car that, quite literally, let the sun in. With its full-length electric opening canvas roof, the Renault 4 E-Tech electric ‘Plein Sud’ brought an open-air dimension to a journey shaped entirely by sunlight, while its 52kWh battery and 150hp powertrain carried it the length of Britain on solar energy gathered along the way.

That energy came from a combination of established solar installations and portable solar-charged energy storage, delivered via a Charge Pro three-phase EV charger provided by Easee, at key points on the route. The result was a complete end-to-end drive, the full length of Britain, without drawing electricity from the grid.

Project leader Jeremy Hart said: ‘You set out thinking this is about getting from one end of the country to the other, but it quickly becomes about everything in between. One stop is a solar farm doing exactly what you’d expect, the next is a cricket club running itself off grid, then you’re looking at research that could change how solar works altogether. Each stop adds something different, and by the time you reach the end, you realise the car has been picking up that same energy all along and quietly turning it into miles.’

Renault 4 E-Tech electric ‘Plein Sud’ is the only electric car in its segment to offer a fully opening roof, combining open-air character with the usability and versatility of Renault 4 E-Tech electric. Its wide 80x92cm opening gives passengers an open view of the sky above, while boot space remains unchanged at up to 1,350 litres with the rear seats folded.

Available in techno+ and iconic+ trim levels, the Renault 4 E-Tech electric ‘Plein Sud’ qualifies for the full Electric Car Grant and is available to order now priced from £27,445 OTR.
