Q CELLS Solar PanelsWrite a review

Went live October 23rd 2018 using 15 panels on an adjustable tilt MT solar pole mount and the SB 6.0 inverter. Glad I bumped the inverter power up from the 5KW originally recommended as the array has maxed the inverter (6.1KW) on crystal clear days. With a clear dark blue sky the panels are putting out a little over 400W each within an hour of solar noon. So they are pretty efficient! In winter we have a little shading in the bottom corner of the array until about 10:30am and the shaded corner of the panel gets hot (200F on a 20F day). Adding Tigo optimizers did not help this as they try to make the shaded panel run at 26V until the corner shade is gone. Still a hot spot. So the panels may have life issues with diagonal shading but other than that they are working great.
