Solar Panels mounted on the Deck

Another of my hobbies that aligns with Amateur Radio is Solar Power. I just installed 2 x Sharp NE-80EJEA solar panels on the railing of my deck. These complement the 2 that are on the shingles of my garden shed (can't show a pic because the are buried in the 4" on snow that we received last night & today)

Yes, all of those white specs are the snow that is still falling!

These panels have several ratings that are important:
Maximum Power (PMax) = 80.0W
Open-Circuit Voltage (VOC) = 21.6V
Short-Circuit Current (ISC) = 5.15A
Operating Voltage (VPMAX) = 17.3V
Current at VPMAX = 4.63A
Maximum System Voltage = 600V
Maximum Series Fuse = 10A

I've wired the 2 panels in series to deliver 24VDC to my charge controller which is a MorningStar SS-20L-24V
