Adding High-end solar panels to roof

Possible: yes. Practicle: no. One solar panel you may get 320Wp and that will cover the whole roof. 320W will not even power the AC when it is properly working. You could rig it to charge the main battery so it gets charged when you're parked as well, but again, you don't get a lot.

 

The best use for such high-end solar panels is to be permanently mounted on your house roof. Maximize the energy they can harvest, in the best available location, never hampered by poor orientation or garage roofs or lousy parking locations. Feed the energy directly into the grid with net metering.

Then use it to charge a plug-in car, or whatever else can make use of it. Minimize the solar panel's 'down time' and wastage.

Has anyone tried to use removable/camping solar panels in the moon roof (for those who have this option)?

 

No worries there. I've never run into any kind of restriction specific to solar panels. Bolt it on and it becomes part of the vehicle, not much different from the side view mirrors. Just an extra piece of glass bolted to the outside of the car- as long as it's done safely & securely you're set.

I agree with above posters- not worth doing. You just aren't going to get enough power out of it to be worthwhile- a Prius roof is simply too small. If you want some free energy invest in a stationary system.

 

research toyota's use of a solar roof on prime in japan. they've done all the heavy lifting.

 

If you just bolt some panels up there, you may end up with a net negative, as the drag from the panels and mounting materials may more than offset any energy inputs from them.

In particular, roofs and the leading edge of roofs are very sensitive to air flow disruptions which produce quite a bit of drag. Laminar flow is the goal, turbulence is bad.

 

That much improvement just isn't going to happen. Not without some seriously fundamental change that throws out today's conversion theory and moves to something else with higher theoretical upper limits.

 

At the prices of current 20+% flex cells maybe worth revisiting

Never will make economic sense but a car isn’t a money making economic investment in the first place.

If it’s thought out and well implemented it won’t be super expensive and will have benefits

It’s really too bad it’s so difficult finding a crashed solar prime for import.
I’ve been watching for about a year and haven’t seen one turn up at the common export sites

 

Who is making these now? When I was looking for such products a decade ago, for an unrelated product proposal, they were not available.

 

Sun power makes the semi flex stuff you see for sale (like what Jack Rickert sells)if memory serves,
EVTV Motor Verks Store: 270 Watt Flexible Solar Panel, Solar, 270wpanel
gotta buy grey market though.

For specifics I would ask iamian or ecky who had active build threads on insightcentral and ecomodder

Sadly google and the sites internal searches are so broken it’s probably easier to just ask them where their threads are detailing how they covered their car in cells.

 

I schedule my '24 Prime so that it charges only during daylight, when my house roof panels are producing. That takes a load off the local coop electric utility.

 

So far, under a Pacific Northwest utility powered almost entirely by hydro, I have no reason to do that. Recharging my RAV4 Prime overnight, and letting my home solar help power neighbors during the day, helps level the diurnal power load and river flow variations.

The net metering rules may be changing somewhat soon as solar production reaches the original net metering caps, and utilities are allowed to change their policies away from what the state legislature originally prescribed. Whether or not we legacy solar producers will be grandfathered into the old net metering rules, or putonto new rules, remains TBD. Several regional utilities have almost reached that cap, mine will be a couple years behind. If I have to go on to new rules, I might change to your pattern.
