Decentralized energy generation at community level is the need of the hour for meeting the increasing load demands. A pilot-scale 1 kW photovoltaic (PV) system was installed at Auniati Satra near IIT Guwahati for studying the effects of its operating parameters at different loading conditions corresponding to the environmental conditions prevalent in Guwahati, Assam (India). The PV system was subjected to constant electrical load both in standalone mode and grid-connected mode during the daytime at eight different loading conditions viz. 20%, 30%, 40%, 45%, 50%, 60%, 70% and 80% and half-hourly data of different parameters like solar insolation, PV energy, PV charge, temperature, and battery capacity were analysed. Optimum loading condition in standalone mode was found to be at 45% − 50% load under normal solar insolation without much burden on the battery bank and can be extended to a maximum load of 70% during the daytime at high solar insolation. In grid-connected mode, load application upto 45% was economically beneficial as less power was utilized from local grid. Though it can be subjected to almost its full rated capacity with input from the ac supply.

社区级的分散式能源生产是满足不断增长的负荷需求所需要的时间。在IIT Guwahati附近的Auniati Satra安装了一个中试规模的1 kW光伏（PV）系统，用于研究在与印度阿萨姆邦Guwahati普遍存在的环境条件相对应的不同负载条件下其运行参数的影响。在白天，PV系统在独立模式和并网模式下均承受恒定的电负载，即八种不同的负载条件。分析了不同参数的20％，30％，40％，45％，50％，60％，70％和80％的半小时数据，例如日照，PV能量，PV电荷，温度和电池容量。独立模式下的最佳负载条件是，在正常的日光照射下，其负载为45％-50％，而对电池组没有太大负担，并且在日照强度较高的白天，该负载可以扩展至最大负载的70％。在并网模式下，由于本地电网使用的电力较少，因此负载施加高达45％具有经济效益。尽管通过交流电源输入，它几乎可以承受其全部额定容量。
