Two big things, available area of solar panels

. You'd spend millions replacing tens of thousands of dollars of Diesel fuel
. But yes it could be done.
You would be surprised at how many people that thought the panel on the roof of some Prius, ran the air conditioner, where really it's all it can do to run a little computer fan to try to pull some of the hot air out of the car.
Available energy from a solar cell is actually quite small, so you have to be super efficient, and use very little energy and accept long re-charge times.
Your use for example, is your battery staying topped up, or are you slowly depleting it? Your use sounds like you could run for a month on battery only.
