The proposed PV Array shall consist of 306 PV modules with a nominal rated capacity of 100 kW plus six 24 kW 480 3-phase decentralized Inverters. The PV panels would be located on the roof of the Gemini North Observatory support building at an elevation of 13,775 ft above sea-level. The decentralized inverters would be located inside the support building in the plant room exhaust tunnel.
