What makes for a good mobile solar panel?

I thought about getting bifacial panels to put on top a white trailer roof. Will from this forum replied they are not a good match for hot summer temps.
So what makes for a good roof mounted mobile solar panel? Are there certain terms that relate to build techniques that handle a mobile setup better?

Hmm, can you find a link to where he said not a good match?
Bifacials should benefit from white roof, but they need to be mounted high enough to get the reflection.

The panels are heavier than standard panels with the extra layer of glass. And hey could be more susceptible to damage from mobile use.

I should have specified a good panel for hot desert temps. (or cold temps too, always fun learning what works in different applications)

bifacial panel thread

As an example are either of these a good or bad choice for a trailer? Or pretty equally good since they both say severe weather?
Q Cell
Solar Ever 410w

I don't really think it's matters if on a trailer or not. I have cheap renogy panels and no issues. I do have the 100w versions and 3 of them seem a ton lighter than the 300w panels I have which makes sense as they'll be more frame to glass

Generally speaking does a higher voltage panel work better in hot environments?

390w Q Cell VOC 48v.
410w Solar Even VOC 31v.

The panel will not know if it is on a house or a trailer roof.
High temps do cause efficiency to go down. Adding more panels overcomes loss of efficiency issues.
Any movement of a vehicle is not enough to damage a normal panel.
It needs air flow under, but not more than an inch or two, I see people mounting them a foot high, fine, but not required, n not great for driving.

Im really surprised panels survive on top of trailers. My plan is to use some type of rubber isolation pad to allow for slight movement. The trailer flexes so much even my bathroom door wont close with just a little bit of trailer jack on a corner.

Was into drones for awhile. I think their accelerometer could measure g forces? Thought about trying to remember how to start one up and strap it down to the trailer floor or a bunk bed next time on the road. I think its quite a rough ride back there. My dirt bikes will shift and bounce around. Had my AV receiver jump 3 inches over a ledge and was hanging by the speakers. Wasnt the best way to start a camping trip seeing that.

I think part of my problem is a triple axle toyhauler with not much weight. I actually hung my bunk bed from springs. It only has about 1.5 inches of travel. Was hoping it would reduce shock to my AV receiver and subwoofer while going down the road. Who knows maybe it acts like 2 people on a trampoline and makes it worse. Keep meaning to get a quad copter on there to see if it helps or makes it worse.

I enjoy reading and learning more on this forum each visit. Still not sure how to pick out a good panel for hot summer temps. Im under the impression some panels are designed for higher temps?

remove one axle? or are they all attached together?
Yes, mis-matched axles and cargo weight can cause harsh ride. By axles I mean leaf springs.
The only time I have heard of solar panels being damaged by harsh trailer rides is from newbies imagining it happening, but not in reality. A big bounce will not do it, only harsh sharp vibrations, which really don't happen through rubber wheels and stiff suspension. You pickle jar falling off the shelf is a real concern, but not damage to a solar panel.

You got me. Will stop worrying about the earthquake that happens while towing. Going to remove an axle and tell the internet its all good.

If you're interested check out Morryde independent suspension. That will take care of any earthquake problems. We can leave water on the counter. It might slide off when braking but it won't bounce off.

Its amazing what moves and what doesnt. The tail end of my toyhauler will launch stuff into space.
While the kitchen sink area is more centered and balanced and an empty cup wont move.
