I think we could put two panels of 50x100cm side by side in an aluminum frame looking after the finish, it could be very clean! (So, I could drop the extra batteries!)
Are there solar panels through which we can see our way? suddenly we could put a panel or two more (as windshield and as "rear window), I make a copy of the plans of the machine and I send them to you?
Yes, I made a long walk, (I accompany my kids who are on bikes) I besides for this purpose, add the two old batteries of the same type in parallel on the bidulle which allows me to do 20Km using only (despite, the consequent increase of weight) 50% of the load, which had been advised me being never to reach the limit of 20%, even better - the less food, the longer they will work! - I followed the advice.
In fact, I want to start with this thing, and then, I'd like to see if it would be possible to electrified a quad! why a quad, because it would pass everywhere! adapting the transmission we could use a Honda type generator that would recharge the batteries as soon as necessary, it would make us ... a hybrid quad that we could pantoner.
Thank you for your response, let me know if you are interested in spending some time there, have projects, it's good for the morale
Sincerely, Lietseu

Yes there are "solar tiles" that are found in the form of semi transparent glazing. I don't know if you can use them as a windshield ... and then there's the weight and the output per m².
