研究目的
To present the techno-economics of a grid-assisted solar powered water pumping system for reducing the load on the electrical grid and mitigating pollution in Medina, KSA, using HOMER software for analysis.
研究成果
The grid-assisted solar PV system is economically viable and environmentally beneficial, with a payback period of about 9.43 years for larger systems and significant reductions in pollution emissions. Installing larger rating solar panels (up to 30 kW) is most beneficial, reducing CO2 emissions by approximately 32.37% for the case studied. This approach supports the transition to green energy in Medina and can be extended to other areas with high solar potential.
研究不足
The study is limited to specific cases in Medina, KSA, and may not be generalizable to other regions. Battery-assisted systems are not thoroughly analyzed due to high costs. The analysis relies on simulation software (HOMER and MATLAB), which may have inherent assumptions and inaccuracies. Real-world implementation factors such as maintenance and variability in solar radiation are not fully addressed.
1：Experimental Design and Method Selection:
The study uses HOMER software for techno-economic analysis of grid-assisted solar PV systems. It involves designing systems for two cases: one with common loads (e.g., water pump and corridor lights) and another with combined residential loads. The methodology includes simulation of energy yields, cost analysis, and pollution reduction calculations based on meteorological data.
2：Sample Selection and Data Sources:
Meteorological data for Medina is obtained from NASA's Surface Meteorology and Solar Energy database and NREL's Renewable Resource Data Center. Load profiles are based on data from cities in Saudi Arabia (Makkah and Yanbu) and typical household appliance usage.
3：List of Experimental Equipment and Materials:
Solar PV panels (ratings from 1 kW to 30 kW), grid-assisted inverters, water pumps (0.5 HP induction motors), and batteries (mentioned but not used in the main analysis). Specific models or brands are not detailed beyond general descriptions.

Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The process involves collecting solar radiation and temperature data, defining load profiles, simulating energy generation and consumption using HOMER, and calculating economic and environmental impacts. The grid-assisted system algorithm prioritizes solar power usage and supplements with grid power as needed.
5：Data Analysis Methods:
Data is analyzed using HOMER software for energy yield, cost-benefit analysis (e.g., payback period), and pollution mitigation (CO2, SOX, NOX emissions reduction). MATLAB is used for additional simulations based on modified models from references.
