200 Watts Solar Project on A Frame

Thought I would share some pics of my solar project. I installed 2 100 watt flex panels on my A122SXR. I had it out around 6 pm last night and it was producing around 150 watts. Was excited to leave it out all day today to see what it would peak out at, but the weather has changed and is cloudy and it only putting out about 20 watts facing due south.

The panels only weigh about 4 pounds each, but since the are toward the top it is harder to raise the roof. Thinking about replacing the OEM gas lift struts (2 x 30 lb) with 2 x 50 lb struts.

Nice job! Any concerns about the MC4 connectors near the top flapping around and beating up your fiberglass?

Thanks. You were my inspiration...ha! They are pretty tight but I will keep an eye on them.

The sun came out around 2 pm. Yeah! I was able to check at 3:15 pm and was at 140 watts. I must have not recollected correctly in my original post as I think I was close to 130 watts last night. Anyway, thought I would be closer to like 170 at this time of day? Maybe not? I assume that noon is the best time of day? I am wired in parallel and am using 10 awg copper wire to the charge controller and battery. Maybe about a 15 foot run. Any idea what i should be getting out of the panels under optimal conditions?

Nice install. I may copy it. Questions:

How are you measuring watts? Direct to a load, or just to the battery?

The most I've seen out of my 200 watts of panels was 9-point-something amps. That was after the battery was down, maybe 25% from overnight use. The amps you get to your battery will depend very much on its state of discharge. If your battery is well-charged, even in full sunlight, your charge controller will trickle you down to well under 1 amp. So let's see, with a charge voltage sitting at say, 13.8V, with 1 amp of charging current, that's only 13.8 watts.

So let's look at my other example, 9.5 amps, charge voltage at 14.4V (the voltage will be raised during the "bulk" charge stage), that's 136.8 watts. Now this is with a PWM charge controller. If you have a MPPT controller, you may well see much better than that being delivered to your battery.

The bottom line is, what you get depends on how much charge your battery needs.

So that brings up some more questions from me: What kind of a charge controller are you running, and how many amp-hours of battery do you have? My opinion is that you want a battery or bank that has at least the number of amp-hours, as your panels are in watts for a good, balanced system.

nice install of the panels -- do you know the efficiency differences of the flex type versus the more solid panel type monocrystalline type renergy type etc - like in DanM's setup -- the flex is clearly lighter -- no frame -- how are the panel affixed?

curious -- why take the wiring through the roof panel -- does the side wall setup - takedown have potential to interfere with wiring path?-- versus -- some extension of wiring to the from storage box or from battery box-- as noted where is the charge controller and type -- battery setup

I planning for a major solar update when I buy my A-Frame next year as I head into full retirement and plan to use it a great deal each year

think of 2 or 4 6volt deep cycle batteries -- so lot of AMPhrs - thinking mounting two panels on the camper as your's and DAnM's project -- but having a portable input into the system - that could be setup and optimally pointed to feed another panel or set of panels into the system if needed or desired -- like the many example of such portable solar feed to charge batteries

I'm reading and researching oddles of upgrade projects for A-Frames and camper -- I currently targeting a A213HW type A-Frame -- and also want to do some work to allow use in colder weather times as well

again nice job

pro - cons of using some 3M tape on the wire runs at strategic spots?
