Photovoltaic Application and Benefit Analysis in K-12 Schools
This paper conducted available photovoltaic areas of a kindergarten,a middle school,and a primary school in Nanjing by both on-site measurements and on-drawing calculation to analyze potential power generation.The results indicate that annual maximum photovoltaic power generation of a standard primary school campus would be 380,000 kWh.However,the daily real-time power generation can only fulfill part of all lighting needs,which is unable to achieve real-time net zero energy consumption.Initial investments of PV are large,but the payback period is normally 7 to 9 years.Comparison of different PV modules indicates that mono-crystalline silicon PV panels have better performance on power generation and economic payback although initial investments are high.Follows the trend of electrification,installation of PV system in K-12 campuses have significant economic and environmental benefits but requiring full understanding of architectural and energy consumption characteristics of school buildings.
