Mounted on a residential roof in Portsmouth NH are 18 PV panels connected to 18 Enphase Mini Inverters. Enphase inverters do several things for a PV system. First and foremost they manage each panel separately so shading on one panel has no impact on the others. In this location there is a large pine tree across the street that the owner would no doubt miss if it disappeared in the middle of the night! The coolest thing Enphase has done is this online monitoring tool. If you click on the far right button in line with Time Lapse you will see the panel output over seven days. This is almost good enough for popcorn. Scroll down just below the panels and you can see the 7 day solar output scale.
