GoGreenSolar.com is a leading supplier of solar electric systems, equipment, inverters, PV modules, rack hardware, etc. Their website has a very handy solar panel array sizing calculator I would urge you to check out. Let me know what you think!
I also have included a link to the complete Solar Panel Kits page. If you are serious about implementing a solar power system at your home, cabin or RV, be warned – you may get lost in this page!
GoGreenSolar is a customer-focused company and they offer easy payment terms and even free shipping on orders over $150. They really do have a system for every budget.
