There's a new CED location opening soon near me. I'll see if they're more willing to bring in some QCell stock.

I can’t wait to hear about your albedo results with snow!Good to know about the cold performance. Just found some new 480's locally for $275! Winter isn't big for solar sales here, so I'm guessing they're eager to move inventory. Now i just need to fab a rack that will get them up above the 3 ft of snow we currently have.
-15F on a clear winter day. We're in the Utah mountains at about 6000ft.
Picking up panels Saturday. Any suggestions on sourcing ground rack components?
I don't want to over build, but these are some big panels, and once or twice a year we get crazy wind gusts that destroy trees and send trampolines into the next county.
Thank you Watchdoc. very much appreciated.You should be able to run 4 of those panels in parallel. Remember, in series.. you add of the voltage (VOC). In parallel, you add up the amperage. The Anker will only draw 20 amps. Those are really nice panels. Very expensive too.
Watchdoc,Another alternative worth exploring is the JJN 200 Watt bifacial 12v 10BB panel. 6 of these panels could be wired 2S3P for 1200 watts and overpanel the Anker. I'm not sure how bifacial wattage gains affect voltage though. This setup would be cheaper than the NewPowa panels as well.
VOC 28.1V (2 in series = 56.2volts)
IMP 8.55 (3 in parallel = 25.65amps) *NOTE: the Anker can only draw 20 amps
The 56.2Volts is awefully close to the 60V max input rating but still less than Anker's own 531 200 watt panel at 57.6V.

Watchdoc,
I took a look at these and they seem good for the price. Could four of those be used in parallel for 800watts, or does that create an issue with too high of an amperage being that the 767 can only draw 20 amps?
I wouldn't. Also, you're working voltage on those panels is very close to 32v and the Anker will likely stay in "10 amp mode" sometimes.Ordered an Anker 767 last week and am expecting it soon. I have 3 Hyundai 305W panels here are the stats:
Nominal Output (Pmpp) W 305
Open Circuit Voltage (Voc) V 39.42
Short Circuit Current (Isc) A 9.86
Voltage at Pmax (Vmpp) V 32.37
Current at Pmax (Impp) A 9.42
Module Efficiency % 18.4
Cell Type - mono-crystalline silicon
Maximum System Voltage V 1,500
Temperature Coefficient of Pmax %/K -0.417
Temperature Coefficient of Voc %/K -0.306
Temperature Coefficient of Isc %/K +0.046*
All data at STC (Standard Test Conditions).
I would like to run these 3 panels in parallel so I can get the 915W and stay below the 60V max however the 29.58A in this configuration has me concerned.
can I input the 29.58A with the Anker at 20A?
Thanks.
