研究目的
To conduct an economic feasibility study for a solar power plant based on PV modules using levelized cost analysis, considering parameters often overlooked by firms, and to examine the impact of high interest rates on such investments.
研究成果
The study concludes that high interest rates negatively impact investments in solar power plants, with a payback period of 13 years and annual profit of $89,467 for a 1 MW plant. Capital cost flow is $5.628/h. Economic conditions, especially in developing countries, are crucial for feasibility, and government policies or technological advancements are needed to reduce costs and attract investors.
研究不足
Efficiency losses due to collector temperature are not considered; pollution-related factors are excluded as operator responsibility; uncertainty of weather is a risk not fully accounted for; solar radiation reflected from soil is neglected; analysis assumes constant interest rates over the plant's lifetime; does not include technological changes or efficiency declines over time.
1：Experimental Design and Method Selection:
The study uses levelized cost analysis and solar radiation forecasting methods. Equations for solar radiation calculation (e.g., Eqs. 1-17) and economic formulas (e.g., Eqs. 18-28) are applied.
2：Sample Selection and Data Sources:
The analysis is based on a hypothetical 1 MW solar power plant in Elaz??, Turkey. Data sources include the Republic of Turkey Central Bank for interest rates, General Directorate of Meteorology for solar radiation and sunshine duration, and cost data from various solar power plant projects.
3：List of Experimental Equipment and Materials:
PV modules (270 W), inverters, construction materials, cables, transformers, etc., as detailed in Table
4：Experimental Procedures and Operational Workflow:
Calculate optimum collector angles using Eqs. (1) and (2), solar radiation values using Eqs. (3)-(14), power generation using Eq. (15), and economic parameters using Eqs. (16)-(28). Assumptions include no efficiency losses due to temperature, no pollution costs, and statistical weather data.
5：8). Assumptions include no efficiency losses due to temperature, no pollution costs, and statistical weather data. Data Analysis Methods:
5. Data Analysis Methods: Use of equations for economic and solar radiation calculations; results are compared with firm-provided data and presented in tables and figures.
