I have been testing a single SP035 with my Anker 767 for a couple of weeks and the SP035 seems decent for the price (which I also got on sale almost half price) with input into my 767 averaging 130-140w at ideal angle and position to the sun. At one point I noticed the SP035 provide 172w which I haven't seen since. I got a 2nd SP035 and tested them individually to confirm they both provide 130-140w same time, sun, angle, etc. and then I put them in parallel and the power into the 767 is only 180w.
SP035 specs:
Rated 200w
VOC-47
VMP-20
LMP-10
The Anker will input only up to 20a and two SP035 panels should be 20a in parallel and volts should remain 20. I have communications in-progress with both Anker and AllPowers to understand why only 180w in parallel. I'm trying to determine is this a SP035 or 767 issue.
I am in Texas and the sun during all this testing has been full on and I've even gone to the extreme of using an app for exact angle, time of day, azimuth, etc. to be sure I compare apples to apples between tests. Anyone else seen this behavior? Am I misunderstanding anything in my calculations?
Thanks,
Shane
