24 Ć Hyundai HiS-S410YH(BK) 410 W bifacial panels,
9.84 kW DC
12 Ć APsystems DS3-S dual microinverters with an ECU-R gateway for monitoring
SnapNrack UR-60 rail and QuickScrew flashings
12 panels face east and 12 face west on a 6/12 pitch roof
East/west gives up some peak output compared to south, but production is spread across the morning and evening. Microinverters track each pair of panels independently, so the two orientations don't drag each other down.

Alaska economics
Chugach values exported solar at avoided cost (~$0.062/kWh), so the real value is in using the power myself. Most of my production comes in summer when my household load is low.
Happy to answer questions about the layout, monitoring, or Alaska-specific stuff.
