There are very few so called solar experts that know how to make a solar system work up to it's potential. Most are just not interested in learning how. Their only interest is $$$$$$ and not in doing good quality work.
If you see an RV with 4 solar panels in bright sun light and they are running the generator, you see a sick solar system, unless they are using the A/C. My estimation is that more than 85% of the RV solar systems are sick, maby more. They work but not very well.
See my post under boondocking, "Solar That Really Works". YOU BECOME THE EXPERT AND DO NOT LET ANYONE TELL YOU THAT YOU ARE WRONG!!!! Have your solar system installed the right way the first time.
I am presently boondocking with Handy Bob of the solar blog. He knows what it is all about. Read his blog and learn as I did (read it 3 times) and I fixed my system before I even met Bob. He is a very nice man.
