I am happy to report that my three new adjustable solar panel mounts and my new 160 watt panel are now permanently installed and actively working on the roof of my 19' to supply my new Nova Kool refrigerator and other essential camping needs with 350 watts of power, pointed toward the sun for maximum performance. For my latitude today, this means 56 degrees of tilt up from flat. I have a picture of the three panels set at this angle.
My original intent was to develop a mount that would give me 360 degrees of adjustment but after a couple of prototypes I didn't like and then realizing that most boon-docking I do gives me some flexibility with trailer orientation I decided to make the mounts adjustable front to back only. This made the design stronger, simpler and lighter. The finished design uses 1/8" thick aluminum angle with all stainless steel hardware, including stainless pem nuts to simplify adjustment. I just finished the 160 watt panel mounting yesterday so tomorrow I will be able to get my first full day of testing...and this will be worse case condition with the forecast rain storm that will start tonight. I have three measurement devices permanently installed on the trailer that measure power consumed by the whole trailer, power consumed by the refrigerator and total power supplied by the MorningStar Solar Controller. With this data I will be able to determine how much power is coming in, going out and total consumed. This info will be included in my next data posting.
This is the adjustable panel mount for the 160 watt panel in the front roof area.
All three panels (350 watts combined) are adjusted up to 56 degrees from flat which is the optimum setting for my latitude today. I made sure there is no shading from one to the other at this low sun angle, worse case condition.
Stay tuned! Steve
