Solar Panels
I have 2 65w panels connected through a controller. I am testing them with the connection wires disconnected. I am getting 20.5 VOC and 3.5 ISC from each panel. The back of each panel says it shoul...

Unless you know for a fact that your solar irradiance is 1000 W/m^2 on a panel at 25C, you can't expect to get the numbers on the label. That ISC sounds about 2x too high for a 12 V (nominal), 65 W panel. What does it show as Vmp and Imp? When I Google "solarland 65W", the first relevant hit says 21.6 Voc and 4.21 Isc.
Are the panels part of a folding suitcase, or some such? The rating might be for the pair, not the individual panels.
I fully agree with what Mike-S said. Sounds to me like there is nothing wrong with the two solar panels if the OP is getting 3.5A ISC on each 65W solar panel.
