While electric cars with integrated solar panels are probably still some way off, this bolt-on gadget will offer EV charging wherever you park your vehicle (in the sun).
A few EV manufacturers have attempted or are attempting to bring mass-produced electric vehicles with integrated solar panels to market, and I’m not aware of any that have succeeded so far. For example, Sono Motors ditched its Sion solar car rollout not long before it was due to commence production. Dutch solar EV manufacturer Lightyear was declared insolvent at the beginning of last year, and while it subsequently emerged from that, the future of its Lightyear 2 model isn’t clear.
Producing a mass market solar EV isn’t an easy task. There are engineering, economic and other reasons why solar cells aren’t a standard inclusion on electric cars (yet). But US company GoSun is gearing up to manufacture the next best(?) thing.
A Stowable Solar EV Charger
GoSun’s EV Solar Charger is stowed on your car – on the roof. When closed, the unit can output 200 Watts. But it can’t charge your vehicle while you’re driving of course as it needs to be plugged into an EV’s charging port. Fully opened, it boasts 1.2kW capacity.
The company claims it can provide up to around 45 kilometres a day range (average of 16-32 kilometres) through solar self-charging depending on the vehicle. 45 kilometres would require an estimated 7 hours of that day parked in full sunshine in mild temperatures based on some really rough back-of-virtual-envelope calculations.
GoSun says the 32kg unit can be installed on vehicle’s roof rack in 20 minutes with two people. Closed, it measures 119 x 122 x 13 cm and fully opened, 622 cm long. Having anything on your roof creates extra drag, but the company says its streamlined profile reduces this. But given the device is something you probably don’t want to be installing and removing regularly, no doubt the drag and weight would have a noticeable impact on overall performance.
I was wondering how this solar charger would cope with a stiff breeze as it looks like it could flap around when fully opened, which could also impact a vehicle’s paintwork. GoSun says it will withstand speeds up to 160 kilometres per hour when closed and winds up to around 48 kph when fully extended.
The charger also has a lithium iron phosphate battery – capacity not mentioned – to buffer solar intermittency; for example, when clouds briefly block out the sun.
The unit is lockable to thwart thieves, but I wouldn’t be too keen to unfurl this in some places. I imagine it wouldn’t last too long – the anti-theft features won’t protect it from malicious damage and this would be a magnet for anti-EV miscreants and other assorted idiots.
How Much Does The GoSun EV Solar Charger Cost?
GoSun is taking USD $100 fully-refundable deposits for the fold-out solar charger, with production expected next year. The price for early bird purchasers is an *estimated* USD $2,999, which at current exchange rates is around AUD $4,500; then add to that shipping and any relevant taxes. Ouch.
It could be a handy, albeit expensive, charging and power solution for camping and off-grid living; particularly if your EV has V2L capabilities. However, GoSun says it also has AC, 12V DC and USB outputs in its power bank; but the AC output is 110V (up to 15A).

I’m wondering how this actually charges an EV when they have minimum charge current requirements?
For example, my Model 3 won’t charge at anything less than 8A, or approximately 1.8kW.

Has solar panels built in to roof, so your claim that there aren’t any is not correct
If your back-of-an-envelope (7 hours sitting in the sun for 45km gained, and any shade will cripple that) is true, it just seems like a gimmick. At the end of the day, you’re going home anyway. You might as well just have some solar panels at home and plug into the wall when you get there.
Too little return to justify the cost and bother.
Although I can imgine a use if going on a round-Australia roadtrip, and worried about getting stranded in the middle of nowhere away from help . 45km a day might be enough to get you out of trouble.
Take it back. Got a use-case. (ABC news story picture)
Maybe they’ll only be able to drive anywhere once every few days, but at least they won’t have a trip-hazard masquerading as an extension cord
Unimpressed. It’s a tiny amount of power for a substantial cost. I’d love to see some independent testing on whether the extra drag negates the energy acquired from the “rooftop” PV. I’m going to call BS on this and put it in the same category as an ashtray on a motorcycle! If the wind doesn’t destroy it some dopey knuckle head will damage it or steal it. I’m all for charging EVs with solar and indeed we do at home with our Ioniq. But I’m not convinced this is a good design concept.
