Just a quick follow up on this thread. A few weeks ago, we tried out our 60W solar panel on a camping trip to The Sierras. The morning sun charged our Type 27 battery to 13+ volts every day, and the battery never dipped below 12V. Worked like a charm with our normal LED lights, fan, shower and water usage. Very pleased! I could see how a 100+ Watt setup would be a good match for Fall and cloudy-day camping.
For housing the solar controller, I cut down a battery box to 4" wide and mounted it on the battery rails. It fits great, and is the perfect size for the controller and cable storage. Let me know if anyone is interested in pics.
Thanks again for the feedback, everyone!
