degraded drag coefficient might take back more miles then this charger adds. But for a city driving where drag doesn't matter much and parking in parking lot under a sun this might have additional benefit of protection from the sun.
As a retired Architect/Engineer and lifelong pilot your point regarding "drag coefficient' reducing the units effectiveness flew into my mind as well but, then I realized two somewhat obvious things. One, you are not moving whilst recharging (so drag is not a factor) and two, the profile of the roof mounted apparatus is not that of a cargo carrier, it is much more knife blade in appearance (timestamp 1:51) so the degree of airflow 'drag' is minimal. I'm also quite sure they've performed some level of wind tunnel tests to validate the shape of their encapsulation. You can apply either aerodynamics or fluid dynamics. Good point though. My concern was theft, wind damage (while deployed) and even vandalism. UPDATE!! I stand corrected. It has been revealed to me my REAL concern about purchasing this unit..." EST. FULL PRICE $2,999* "
This would be useful when camping or parking off grid (outside) for extended time. And reasons given in the video. Caveat would be wind. How to secure the panels when it gets windy? As it is set up the paint on the vehicle would take a beating.
Thanks for watching the content! We think, the cost would be around $100-$150. Please visit the company website for actual details: gosun.co/products/ev-solar-charger-deposit.
Without an output transformer to provide galvanic isolation between that portable, high frequency, transformerless inverter's DC rail and its AC output, during a failure of this inverter's control circuitry, you are at high risk of passing high amperage DC current through to your EV's onboard charger. This can not only damage it, but will also void your EV's warranty. You may be able to charge your EV now, but one day, you're inverter will fail as they all do, and you will probably smoke your EV's charger. A much better way to charge your EV off grid, is to use a low frequency, transformer based inverter.
This video is a perfect demonstration of total ignorance of solar power, and how much electricity is needed to power a vehicle. You would have to be utterly insane to purchase such a thing. Completely worthless for its stated purpose. AND VERY OBVIOUSLY SO.
Solar panels lose their efficiency very rapidly. Also, the 20 miles added range is due to the solar panels adding 3-4 miles range every hour or two. Theft while charging will probably be an issue, and so will parking garages. It is a novel concept, but in practice it's success may be rather limited.
We agree, concept it great! This product might be good when someone is out remote camping and needs some option to charge their EV. Hope the charger capacity will improve over time!
@@johnreeves7261 By the time solar panels are installed since their manufacture date they have already lost upwards of about 5-10 percent of their efficiency to absorb sunlight and turn it into electricity. I will have to double check, but I believe it has to do with the silicon layer in the solar panel becoming oxidized. However, there have been some recent developments in solar panel technology that may be able to address this issue.
@@johnreeves7261 Could you define low? If the degradation rate is low in comparison to the rest of the competition, that makes sense. I am not doubting nor denying that they are capable of producing tons of energy in comparison the the amount of maintenance and effort you have to put in.

I had suggested to Mitsubishi about integrate solar on there PHEV outlander. Kind of a good idea

For pickup trucks. The solar panels can be stored in the bed. Pull out when parked for extended periods.
nice idea

Great point! For camping or parking off Grid, may be we need a Solar Tent :)
How to buy this and what is the cost?

Only 1.2 KW? and what about info on the inverter to needed to convert the electricity generated from DC to AC?
We agree, 1.2 kW sounds nothing! Technology is pretty new, hope there is significant process over years. Thanks for your comment.
@@emobilitytrends what about info on the inverter to needed to convert the electricity generated from DC to AC?
@@OG.551.98 Looks like they are doing DC directly, All that would need to a boost converter to output around DC 400v

Most solar panels are efficiency warranted for, at least, 25 years. How, then, can you claim "solar panels lose their efficiency very rapidly"?

@@itsskip Read the 40 year power warranty on Maxeon Solar Panels. Their "efficiency degradation" rate is very low.

For sure im not driving my ev with this on the roof
lol it’s not meant to be driven with it on!! 😂😂😂
