In today’s world, where global warming is one of the greatest human challenges, sustainable energy generation is becoming increasingly relevant. The use of green and clean energy sources is the best way to minimize CO₂, CO, NO_X and other emissions of conventional energy usage. Solar photovoltaic (PV) systems are more beneficial and an exciting application to set up an eco-friendly green educational campus. In this regard, the potential sites within Tribhuvan University, Institute of Engineering, Purwanchal Campus, Dharan city, Nepal are analysed for grid-tied solar PV power plant installation to meet the 100% energy demand of the campus using energy, economic and environment-friendly analysis. The daily, monthly and annual load and solar irradiance data of past years of the campus have been analysed to estimate the solar PV plant’s capacity and system performance using PVSYST V7.0 software analysis tools .The simulation results show that 110 kWp of solar PV power plant will be sufficient for the entire campus to qualify for the first fully green-powered campus in Nepal, which corresponds to fulfill 66.4 MWh/year daytime energy demand out of total 161 MWh/year energy consumption of the campus with a capacity to generate a total of 181.5 MWh/year energy from the designed solar PV system. The result also shows that 115.1 MWh/year of surplus energy produced from the PV power plant can be injected into the utility grid to yield considerable savings in utility cost. On the basis of these results, campus authorities and stakeholders may commit to investing and implementing of this project to ensure that the campus is completely green.

尼泊尔的可持续绿色校园：3E分析

在当今世界，全球变暖是人类面临的最大挑战之一，可持续能源生产变得越来越重要。使用绿色清洁能源是减少CO ₂，CO，NO _X的最佳方法以及常规能源使用的其他排放。太阳能光伏（PV）系统在建立生态友好型绿色教育校园方面更具优势，并且是令人兴奋的应用程序。在这方面，分析了尼泊尔达兰市Purwanchal校园工程学院Tribhuvan大学内的潜在地点，以并网太阳能光伏电站的安装方式来满足校园100％使用能源，经济和环境的能源需求-友好的分析。利用PVSYST V7.0软件分析工具对校园过去几年的日，月，年负荷和太阳辐照度数据进行了分析，以估算太阳能光伏电站的容量和系统性能。仿真结果表明，太阳能光伏发电量为110 kWp该工厂将足以使整个校园有资格成为尼泊尔第一个完全绿色供电的校园，这相当于满足校园每年总161 MWh /年的能源消耗中的66.4 MWh /年的日间能源需求，该容量可通过设计的太阳能光伏系统产生总计181.5 MWh /年的能源。结果还表明，可以将每年从光伏电站中产生的115.1兆瓦时的多余能源注入公用事业电网，以节省大量的公用事业成本。根据这些结果，校园主管部门和利益相关方可以承诺对该项目进行投资和实施，以确保校园完全绿色。可以将每年从光伏电站中产生的1 MWh的剩余能量注入公用事业电网，以节省大量的公用事业成本。根据这些结果，校园主管部门和利益相关方可以承诺对该项目进行投资和实施，以确保校园完全绿色。可以将光伏电站产生的1 MWh /年的剩余能源注入公用事业电网，以节省大量的公用事业成本。根据这些结果，校园主管部门和利益相关方可以承诺对该项目进行投资和实施，以确保校园完全绿色。
