Abstract:
Poissant, Y., Thevenard, D., Turcotte, D., 2004. "PERFORMANCE MONITORING OF THE NUNAVUT ARCTIC COLLEGE PV SYSTEM: NINE YEARS OF RELIABLE ELECTRICITY GENERATION" Commissioned Report to INAC.
A 3.2 kWp grid-connected photovoltaic (PV) system was installed on the fa?ade of the Nunavut Arctic College, Nunatta Campus in Iqaluit, Nunavut (63.4 ¡ãN) in 1995. The project has two main objectives: to gain experience in the construction, monitoring and maintenance of a northern gridconnected PV system, and to serve as a demonstrator of the use of PV in the far North. This paper summarizes nine years of monitoring results. The monitored data includes current from the PV array, array voltage, AC power delivered, horizontal and vertical irradiances (both measured with LiCor and Eppley pyranometers), ambient temperature, and array temperature. Climatic and solar radiation conditions at the site are reviewed, and the performance of the system is assessed from a component perspective (PV array, power conditioning unit) and from a global perspective (system efficiency, reliability, annual yield and performance ratio). The system has delivered on average 2,016 ¡À 200 kWh of electricity on an annual basis with no interruption of delivery. Thus, the system has demonstrated with success the reliability of grid-connected photovoltaics for the far North.
