Wow, well over 16 W out of a 15W HF panel.  You must be lucky to get one that does that.  The HF 5W panels I bought a couple of years ago were lucky if they put out 3.6 W max when new and now they do about 2.5W when charging a 12V battery.

When I first got these about a month or two ago I set up 3 panels from a kit on the stand they came with, they all did ok but each of the 3 varied in open volts and shorted amps some. The sun was not as good then as yesterday.

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.

Spelin and tpying are my strong points, not electronics.
