Solar panel on roof?

You guts mount e'm flat or use the angle mounts. PITA to climb on the roof but if you do where do you set the angle, towards the awning? Seems like that is the place my trailer set to the sun the most.
  • I have a factory installed 55w panel on roof with a controller mounted inside. I have a 130w, with portable controller, that on prior trailers I bungee to a four foot ladder. Just thought I would mount it on my roof because all wiring and controller is installed. (Yes installed controller and wiring will handle it). Would be nice not to have to set it up each time but I know from experience it works much better if I keep moving it to the sun. Decisions, function over convenience.
  • With the cost of panels today if you have enough roof landscape its pretty cheap to over panel the system and not worry about tilting.

    It just seems that many people on the forums say that climbing up on the roof chasing the sun gets old quickly.

    I agree! Did my install this spring and learned quickly while doing the work I did not want to be going up & down even tho I made tilt brackets out of alum angle. I installed 2 1/2 extra panels to make up for not tilting and cloudy days (720W to 440 amp-hrs). Built the system in three 24v arrays in parallel with two panels in series in each array to offset any possible shading in a campsite (six 120w panels total). Very pleased as the system has tested as designed. With total tree shading & early evening, system was still putting out in MPPT last evening. No more climbing on the roof than necessary for this old guy! Just think about putting the panels down in a wind storm or during a rain storm should you need to leave.

    Did not mean leave because of the weather but because you HAD to be somewhere. Like work, doc apt and etc.
