I'd wonder if the % area that you were covering matched the loss. You covered 1/15 of the 15 panel, but since your towel size remained the same. It means the % area covered increased for each of the other panels. It doesn't invalidate your results, Shade matters. :) But just curious on the numbers.
Mirrors my basic tests in Oz. Just a small amount of shading on any Poly panel results in a huge drop in wattage. It's surprising that even having a tilted panel on the ground with grass mulch blown across the bottom side dropped wattage hugely. Nice test. Good to see my experience confirmed. Justification for having separate solar strings on their own individual controller at different orientation/locale.
My panels are the same. Tilted on the ground. We get a dusting of snow in the winter and lose over 50% production until I broom it off. Thanks for the comment!
I have a few briefcase style solar panels. I built a small stand that’s tilted at 32 degrees. Your 15 panel is probably difficult to get angled but I wonder if the results would be similar if you angle them
@@OffGridBasement Thank You for replying back. I am about to install 2 100 watt solar panels on my Trailer Cabin. I was going to mount them on the roof but then i am bound to full sun for placement. My brother said I needed to make them a ground mount and chase the sun through out the day .I have plenty of solar cable for it.
Do you have a spot where you won't be dodging tree shade? Also, you probably want to wire your panels in parallel if shade is a big issue throughout the day. Good luck and have fun! @@modwrath810
@@OffGridBasement Well its more than just a cabin on a trailer , it also is my portable ground blind I use for deer season. With that being said I tend to place it either right smack in the timber or along a tree line. , And I have pondered between series or parallel for my panels. If I am correct, series increases me volts and parallel increases my amps. My brother who is a certified mechanic says batteries charge best at about 5 amps. Right now my solar charge controller is capable of 12, 24, 36 and 48 volt., with 2 100 watt solar panels , although their specs are slightly different. and believe it or not a marine battery with 12 volt marine battery with122 amp hours. I have had very good luck with this battery as it runs my winch for my trailer. Out of all the you tube channels I have watched I find that yours is by far very informative and you break things down so we noobs can understand. Your insight is very appreciated and I thank you for it.
hi i have 2 dokio 100 watt panels was thinking of getting 2 more and putting them on opposite sides of houseboat so that sun can hit only one set at a time plus some water reflection early and later in day.. it would give me little more output on cloudy days to. they are very light panels at 2.3 lb a piece.. my charge controller. is only 20 amps good for 240 watts of panels renogy. at 12 volts. should work i think.would be nice to test
