About the MATCH School Photovoltaic System The system was designed and installed by Solar Design Associates Inc., of Harvard, MA. The installation took place over a five day period in late November and early December with help from IBEW Local 103 electricians from Hamilton Electric Co., Inc. The PV system utilizes a PowerLight® mounting system. This system lies flat, on top of the roof with no penetrations. Each PowerLight tile is comprised of two Shell® photovoltaic laminates mounted to an extruded polystyrene backer board. The tiles interlock in a tongue and groove fashion and are secured around the perimeter with a ballasted curb. The entire array is comprised of 144 of these PowerLight® tiles. Additional blank T-Clear tiles were used to create walkway through the middle of the array for roof top equipment access. A 20kW Xantrex® inverter interfaces the photovoltaic system to the school's distribution system. The system is monitored with a National Instruments® Data Acquisition System which was also designed and installed by Solar Design Associates. The data acquisition web presence was developed with assistance from Skyline Technologies Inc. Contact Us Solar Consultant: Solar Design Associates, Inc.
