Economic feasibility of campus-wide photovoltaic systems in New England

The average payback period of a campus-wide PV system was calculated as primarily 11 years, within a range of 8-12 years, and was estimated to reduce overall building operating expenses by $250,000, or 8%. The economic parameters such as NPV and IRR also validated the investment worthiness. The results of the study could be used to analyze or further develop feasibility studies of PV systems at other universities in Connecticut and neighboring states that share similar climatic characteristics and economic factors.
