Performance Analysis of Solar PV System of TUTH Kathmandu Nepal

The renewable sources such as solar wind biomass etc. are often used for electricity generation for their availability no green-house gas emission and solar photovoltaic is major among them. Many On-Grid PV systems are being installed around the globe nowadays to reduce electricity dependency on a single source and thus enhance availability of energy sources. Kathmandu Nepal receives sufficient sunshine with insolation around 4.5 to 5 kWh/m 2 /day which justifies essence of grid-connected solar PV installations. A 115.2 kWp solar plant has been installed at Tribhuvan University Teaching Hospital (TUTH) Maharajgunj Kathmandu to fulfill its own load demands and reduce the electricity bill of the building. The detailed On-Grid solar PV system is modeled and performance parameters such as Performance Ratio Specific Yield and Capacity Utilization Factor as defined by IEC are estimated using simulation techniques from PVSYST. The actual parameters are calculated and a comparison is made with simulated parameters. Thus necessary measures for optimized generation have been suggested to the concerned authorities.
