研究目的
The main objective of this paper is to study the viability of 1MW grid-connected photovoltaic system in Qassim region.
研究成果
The simulation results showed high energy productivity and both technical and economic indicators are high compared with similar systems in different countries. The LCOE was 0.0359 $/kWh and the SPBT was 13.7 years. The GHG emission reduction was estimated at 1755 tons of CO2 annually. The study proved the viability of the proposed system without any governmental incentives or grants.
研究不足
The study assumes no governmental incentives or grants, which could significantly affect the economic viability of the system. The analysis is based on current prices of PV modules and balance of system components, which may vary over time.
1：Experimental Design and Method Selection:
The study utilizes real-time solar irradiance data for a 1MW grid-connected PV system in Qassim region, Saudi Arabia. Technical and economic indicators are used for analysis.
2：Sample Selection and Data Sources:
One-minute meteorological data provided by King Abdullah City for Atomic and Renewable Energy (K.A.CARE) recorded by the meteorological station hosted in Qassim University.
3：List of Experimental Equipment and Materials:
PV modules (mono crystalline, manufactured by SunPower), inverters (manufactured by China power), step-up transformer, and other balance of system components.
4：Experimental Procedures and Operational Workflow:
The PV system is simulated based on the recorded meteorological data to evaluate its technical and economic performance.
5：Data Analysis Methods:
Technical performance indicators (Yield Factor, Capacity Factor, Performance Ratio) and economic indicators (Levelized cost of energy, simple payback time) are calculated and compared with similar systems worldwide.
