Battery volts X charging amps was equaling about the same watts as I posted. I just didn't post the battery stuff as it would have perhaps confused things a bit more. Durring the day one SLA was full charged and I switched to a less charged SLA to charge it up some also. That would have caused the volts to rise durring the day then suddenly drop due to switching batteries. Also the voltage shown would then have been the battery volts, not the volts of the panel itself. Also the amps would then be based on the battery volts as well to a point not the amps of the panel. So with the battery charging I was getting the same watts, but showing those numbers does not realy show what the sun was doing with the panel as the battery was different volts and amps numbers, only the watt numbers would be the same.
I probably should have wrote those battery numbers down and posted them also, but I just checked them and didn't keep track since the watts were working out the same.
The watts are in line with what the panel should have been producing also. 15watt panel ranging from 13.68-16.22watts and back down to 8.44watts again in evening.
This being a nearly brand new panel it should be making a little more watts than actually rated also.. nothing to lose
Spelin and tpying are my strong points, not electronics.[ Parent ]

So many things can change test results like this though, alittle more or less haze while testing one panel than when testing another, and we don't really see the minor haze enough to notice a slight diffence that could lower the numbers a tiny amount.. nothing to lose
