A solar panel on a pickup sounds like free miles — this one refuses to give them
The D-Max EV gets a factory-fitted solar panel in the UK, but it never touches the traction battery. Its real job is keeping the 12-volt alive so fleet trucks actually start on a cold, grey morning.
A solar panel on the roof of a pickup — sounds like a dream of free miles, doesn't it? Here's the twist: Isuzu is offering this option on the D-Max EV in the UK precisely because it has nothing to do with range. The panel is fitted right at the factory, before the truck ever reaches the customer. Its job isn't to top up the traction battery, but to quietly keep the 12-volt one healthy — the very battery that most often leaves commercial vehicles refusing to start in the morning.
The technology comes from Genie Insights. The 75 W panel mounts on the load-bed roof: 947 × 687 mm, just 3 mm thick, weighing 2.5 kg. On a pickup that hauls more than a tonne, that's a gain the scales barely notice. The fleet notices, though — wherever trucks sit idle for long stretches, power auxiliary kit, or live on short hops from point to point.
Inside sits CIGS technology, built not for southern sun but for ordinary daylight. For Britain that's the whole point: overcast skies and winter shouldn't wipe out the effect. Built-in diodes let the panel keep working even under partial shade, and the technology itself, according to Genie Insights, has already survived six winters in real commercial fleets. Not a showroom prototype — a workhorse.
And none of this grew out of a glossy slide, but out of practice. Over two years Genie Insights fitted solar systems to around 450 commercial vehicles at Network Rail — mostly vans. In all, the company has supplied UK operators with almost 15,000 kits; its customers include British Gas and BT/Openreach. After trials with IM Group, Isuzu's importer, demand was strong enough to make the system a standard factory option. It's built in Britain, by the way, and certified to ECE R10.
For the D-Max EV, this lands squarely on target. Isuzu's first fully electric pickup in Britain wasn't made for the private EV enthusiast, but for companies that care about other things: an easy handover into the fleet, reliability, less downtime, and predictable auxiliary electrics. Factory fitting takes away the headache of third-party installation — the customer gets a finished truck, not a modification project.
And the point here is bigger than one pickup. Electric commercial vehicles win not just on big range figures — more often their fate is decided by the small things that cut the risk of a breakdown mid-shift. A 75 W panel won't turn the D-Max into a self-sufficient power station. And it isn't meant to. A fleet doesn't need an impressive gain of miles on paper; it needs one simple thing — for the truck to start in the morning and head out on its route. That's what they're paying for.
