I hope this information will be of help to someone looking for solar panels. I recently made a purchase of six LONGi 320 watt 120 cell LR6-60HPH panels. I got them from A1 Solar Store. The price was $152 each, plus a flat rate shipping of $175. So for $1087 complete, I got a 1920W solar array. Delivery was very fast per freight. They were packaged very nicely on a wooden pallet with a cardboard pylon on top so that nothing could be stacked on top.
The panels are Mono, have PERC 120 half cells, 19.4% efficiency and black aluminum framed. The VOC is 40.9V and 9.43A. I tested them all in pairs to see if they were OK after delivery. All functioned much better than expected. They all performed above spec in full sun at an air temperature of 56 degrees. They were connected to a Victron Energy 150/45 TR. Each pair performed great. I expected about 580-600W, and I hit over 655 a couple of times. See pic below of the snapshot. That is a steady 647W.
I have panels from SunPower, AcoPower and HQST. Only the SunPower perform to spec in cold temps. the AcoPower and HQST all perform well under spec even in cold temps. That is why I am so surprised at the LONGi panels. If anyone has any questions about these panels, please let me know. I will try to answer them the best I can.
