Project Summary

The Unitarian Universalist Church of the Upper Valley in Norwich already had electric power donated from a working solar system when it decided to mount another on the rooftop. One of the factors in the decision was that its new building had beautiful south-facing roofs, and people thought it would be a shame to let it go to waste. The new system is a community solar array, with church members participating in net metering.

This system has 45 solar panels, each of 350 watts, providing a total power of 15.75 kW DC. It includes 45 SolarEdge P400 Optimizers and a SolarEdge HD Wave SE11400H-US inverter. The racking is IronRidge XR-100, using EcoFasten QuikFoot attachments.

The UUCUV system was completed in 2018. Its members blessed the panels on Sunday, December 30th.
