I tried to use and like solar. Too high a cost.... Frank...........30 years Ca electrical contractor........Be well.
I've had a very different experience with my solar set up.
First, the cost was reasonable. I paid around $1100 for the panels, wiring and charge controller that will run everything I need it to (small refrigerator, lights, water pump, inverter for tools and kitchen stuff). Whether you're running a generator or not, a bus/RV should have a battery bank so I'll ignore that cost. After all, it'd be silly to have to start your generator to turn on the lights on the way to the bathroom at night.
I did the calculations of purchasing and running a Honda eu2000 and a cheaper Champion 2000w generator. My findings were that - as of beginning of August this summer - the solar system has already paid for itself vs buying either of those generators and fuel.
Cleaning being a problem? Nope. I've only had to wipe bird poop off once. The rain has taken care of the rest. Even when on the road driving around Texas last winter. A desert dweller may have a different experience.
Also note that battery banks should only be bulk charged at a maximum amperage that is determined by the manufacturer., then the amperage tapers off to finish charging. Because of this, running a cheap, non-inverter generator to charge batteries is a wasteful affair. The cheaper generators don't throttle down in sync with the battery charging requirements.
But the biggest, best thing about solar? Silence!
I've had the unfortunate experience of camping next to generator powered RVs a couple of times. I try to avoid the situation the best I can, but sometimes it just happens.
