Solar Thoughts
Not knowing where you are makes it difficult to make a recommendation. But from our excperience (we've been dragging our RV around the country for 8 years and live full-time on solar), the best price and most knowledgeable people are generally down in the southwest ... Quartzsite (AZ) probably being one of the better ones at this time. There are several distributors and installers there ... Discount Solar and Solar Bill being just two of them. I don't know whether they are open year-round as they get most of their business from snowbird traffic.
To my best knowledge, a 75W panel (either Shell or Kyocera) can still be had for $350. Some negotiation may be required.
As for general information regarding solar panels, there's a well of it to be had on the internet ... the only advice I could give, before you purchase, is to become thoroughly knowledgeable about the subject, including your own personal expected usage (eg. are you going to be using them part-time? full-time?)
One of the things I did wrong when we first decided to go solar was I didn't get a large enough regulator and thus had to upgrade at a later date when I found I needed more panels than I had anticipated. A lot of people find generators more to their liking (perhaps because of capital cost) but there's a lot of downside to them. Again, the only thing I can say ... the more info you get, the better decisions you'll be able to make.
We live in a 5th wheel 6 months of the year down here in the southwest. We have 5 panels - 4 75W and 1 120W. This provides us with all the power we need ... though we do carry a small i1000W Honda for emergency use (eg. getting stuck in a snowstorm in our travels back and forth to Canada).
Hope this helps.
