John E Davies Posted March 13, 2017 Share Posted March 13, 2017 I am a little confused because I have a factory pic from an unknown date showing them at 45 degrees, but I haven't seen any actual camping pics with them deployed like this. Is this just a "service position"? Will I be able to easily do this when camping with the use of my portable ladder? I live pretty far north and the sun can be low on the horizon some seasons. This would really help on marginal cloudy days. For those who may not know..... a 30 degree tilt will give up to 18% more output at my latitude (45 deg N) for a fixed residential installation. For a camper array that is easily adjusted, the numbers would be significantly higher in winter if the panels were raised more. Also a dead flat panel is not desireable because dust will accumulate and it will not "self clean" when it rains; a dirty array is very inefficient. This doesn't matter quite so much on a trailer compared to a building since it is so easy to reach them to get the grime off. But if you were parked long term, it would be very beneficial to position the panels at a small angle, three or four degrees at the very least, for good drainage. https://www.civicsolar.com/support/installer/articles/effect-array-tilt-angle-energy-output And his followup on azimuth (bearing) vs efficiency. https://www.civicsolar.com/support/installer/articles/effect-azimuth-angle-energy-output Oh yeah, I would install a red streamer on my steering wheel if I tilted my panels, as a reminder to not drive off with them raised! This will be my first solar experience and I am still learning.
