Solar panels on a vehicle are useless. There's simply not enough surface area available on a vehicle to fill more than a tiny fraction of the battery. And definitely nowhere near enough to drive.

https://solarpowerrocks.com/solar-basics/how-much-electricity-does-a-solar-panel-produce/
"A typical solar panel produces around 200 watts of power. "

The "typical" panel they are talking about is too big to fit on the SRK. A pretty efficient Sanyo panel that produces 205W is 35"x52". Or 3'x4.5', if that's easier to visualize. At 200W, that would take 5 hours to produce 1 kWh of power. The Nissan Leaf typically has a 24kWh battery. (Some have a 30 kWh?) At 12 hours of strong sunlight per day, that would take 10 days for one solar panel to charge the battery, even assuming that you could get a panel that size to fit the car. (You can't.) That's also a serious overestimation of the actual amount of daylight you would see, and the amount of energy you can get from that daylight. At my location, that panel will only provide 1.1 kWh per day. (According to the calculator at http://www.wunderground.com/calculators/solar.html)

The Nissan Leaf gets ~90 miles per 24kWh. Or about 3.75 miles per kWh. At 5 hours per kWh, you're talking 1.3 hours to generate enough electricity to drive 1 mile. Assuming full efficiency of the solar panel, and bright sunlight for that whole hour.

Now, if you live in Death Valley, you might get better charging efficiency. So, I'll give you 1 hour per mile. (But if you're in Death Valley, you'd probably want the AC, which would greatly reduce your range, so you wouldn't get 1 hour per mile anyway.)

Oh, and that Sanyo solar cell would set you back almost $1,400. Getting it custom-fitted to conform to the roof of your car? I'm not even gonna go there.

A Dutch University Has Just Won Australia’s Solar Car Race

competitors in the nation’s solar car race, of which the team from Delft University in the Netherlands won its second victory in a row on Thursday.

Held once every two years, the World Solar Challenge is a friendly testing ground for cars that run on nothing but the sun. The hope is that one day the technology will find its way into consumer products, the BBC reports.

This year more than 40 teams from universities and schools around the world set off from State Square in Darwin on Oct. 18. Five days later, after 37 hours, 56 minutes and 12 seconds of driving, Delft’s Nuon Solar Team’s car Nuna8 was the first to cross the finish line at Victoria Square in Adelaide.

It was a tight race. Nuon’s countrymen from Solar Team Twente and its car Red One joined the revelry just eight minutes later. Japan’s Tokai University took third.

How do you celebrate after five days in the scorching Australian Outback? The orange-clad students jumped in the square’s fountain, naturally.

Well, seeing as the SRK isn't fully enclosed, I'd probably go with the jacket too unless it's pretty warm where you live/work. But yeah, I agree helmet is excessive when it already has a windshield, roof, roll cage and seat belts.

Yeah I guess I should have stated that I live in Southern Arizona. ;)
