If you need help with system design you can work with a single vendor for most of your system components and they should be able to provide design help. The best thing is to work with someone who understands the special needs of RV's. My first choice would be AM Solar (Greg Holder). Their business is RV solar, they can supply almost all the required solar parts, their prices (for the most part) are reasonable, and their preconfigured systems are very nice; http://www.amsolar.com/. John Palmer (Palmer Energy Systems, http://www.jolynenterprises.com/) also specializes in RV solar systems. For parts and design help from the residential market try http://www.thesolar.biz or http://www.backwoodssolar.com. I'm also willing to answer questions if you contact me directly - see the About Us section for our email address.

 

A complete implementation of an RV solar system, including an inverter, and batteries (from scratch) is going to cost in excess of $3000, depending on sizing and components selected. Time spent in the design phase is time well invested. Mistakes can be expensive. If you have the system installed instead of doing it yourself make sure you find a good installer. You want someone who will charge by the hour - not a flat rate. You are more likely to get a good job if the installer is not rushed, or loosing money on the work.
