Installed a larger refrigerator about a year ago,one panel was not doing the job. I purchase two new panels from Grape Solar. I purchased the GS-Star-180W-US.pdf
. from Home Depot, with there ship to store option you don't pay shipping. It only took a day for me, but then I am just up the road from Eugene. They have a specific panel that is made in the USA, the USA version is normally $258.00 for a 180 watt panel, or $230.00 if you want the Import version. It is just as wide, but a inch shorter in length as Kyocera KD140GX-LPU 140 Watt panel .
Vmpp of 19.67 volts, Impp of 9.77A
For installing I did away Yakima Landing Pads and just mounted aluminum angle directly to the Yakima tracks, I purchase the landing pad replacement hardware instead.
Because the existing panel also had MC4 connectors, wiring was easy as I just used a set of MC4 Parallel connector / Adapter / 1M2F+2M1F /TUV / T Branch Connectors
I have a used Kyocera KD140GX-LPU 140 Watt panel , if someone local to Portland wants to make a offer..
