GMCS applied to Vermont’s Public Service board, on September 18, 2015 for a Certificate of Public Good to install and operate a 150 kW photovoltaic solar array at 199 E. Village Road in Waterford, VT. Its Certificate of Public Good CPG #6703 was issued Nov. 25, 2015.

Site geotechnical testing occurred on January 19th. Soils and post driveability, pull resistance and lateral strength were tested. These are used to set design parameters for racking systems. Our installation contractor mapped property corners to define exact array layout. GMP’s interconnection plan has been finalized with their St. Johnsbury office.

 

On Wednesday, April 20, Ben Gordesky (Renewable Energy Manager for DC Energy Innovations, Inc (our Burlington based project manager and installer)) and I met with Darrell Matthews of Matthews Excavating of Waterford and laid out the construction access road. Darrell’s crew built the road on Monday/Tuesday, April 25/26. Darrell will also perform trenching for conduit.
Ben laid out the locations for the 15 racks using a TotalStation – seven rows of two racks and one row of one rack, for 15 total racks. The racks are oriented 20 degrees west of east-west so to capture the value of the slight southwesterly slope and excellent western view from the site. Each rack will have forty four 325 watt (DC) SolarWorld panels on them. The panels on these racks will be connected proportionally to twelve 12.5kW Fronius Primo Lite inverters to get us to our permitted 150 kW (AC) output.
