Got this panel, I believe 200 watts, nothing on it indicating a brand. There are 4 flat contacts sticking out the back, I'm just trying to figure out on how to wire it without burning anything. Any suggestions?
Agree with @Bud Martin.Posting good clear pictures will be a great starting point.
Voltage is just based on number of series cells 0.63v Voc per cell, 0.52v Vmp per cell @25 degs C@RCinFLA thanks so much! Just measured the voltage, from 2 outer tabs 42v, 14v and 28v on second and third tabs. Looks like a 300 watts panel then? Which junction box should I buy then?

You need the right number of tabs - e.g. a 4 tab connection 'type' in your case AND diodes that can handle the amps.It's exactly 156mm! 8.7amp? How do I figure out which junction box to buy?
