x2. I don't think RV technicians know much of anything about electricity. If you want it installed by someone else, it may behoove you to design it yourself, or have a reputable solar dealer do it. I think it's a good idea to really understand your system, like what voltages are where and why the wires are a certain size.
As a regular boondocker I wouldn't even consider it sans solar. I have 830w, which works out just about right for microwave, toaster, TV, and all other uses. I do have to admit I get a bit irritated when I find myself camped near someone who has to run a generator to watch TV. Generators are a lot easier to understand than solar and inverters.. I guess that's why. The only generator needs I have are for air con. With a 48v LifePo battery I can run my air con on the road to keep the cat cool, but not for very long. The neatest thing about solar is it charges your batteries at full power going down the road.
In 18 years I've had one BP panel short out, and BP replaced it without question. The foil connections can overheat and burn out. You can see that happening on the front (and back) of the panel... it's a brown spot. Never a problem with leaks.
