研究目的
To compare data from various sources and methodological approaches for calculating solar radiation parameters to choose the most reliable information for rationale of solar panel plant use, and to investigate the effect of deviations on the effectiveness of solar panel plants for off-grid consumers.
研究成果
The comparative analysis showed that deviations in solar radiation data from different sources are small (5-10%), and the detailed approach provides higher radiation values, leading to shorter payback periods for solar panel plants. The choice of methodological approach has an insignificant effect on optimal power determination. A simplified approach is sufficient for economic viability studies, but detailed calculations are necessary for precise technical and economic parameters in specific settlements. Payback periods are approximately 10 years and depend more on diesel fuel prices than latitude location.
研究不足
The limited net of actinometric meteorological stations in Russia may affect data accuracy. The detailed approach requires complex calculations and recent meteorological data, which may not be readily available for all locations. The study is focused on the Sakha Republic, so results may not be generalizable to other regions without similar conditions.
1：Experimental Design and Method Selection:
The study used a comparative analysis approach, comparing solar radiation data from reference books and meteorological stations, and employing two methodological approaches (simplified and detailed) for recalculating solar radiation on inclined surfaces. The simplified approach uses reference data on direct and diffuse radiation under average cloudiness, while the detailed approach uses models (e.g., Klucher's model) and recent meteorological data to estimate radiation constituents.
2：Sample Selection and Data Sources:
Settlements in the Sakha Republic (Yakutia) were selected based on latitude differences, availability of solar potential data, and presence of solar panel plants. Data sources included reference books (e.g., [4], [5]), meteorological stations, satellites (e.g., NASA SEE database), and online databases (e.g., rp5.ru).

3. List of Experimental Equipment and Materials: Not explicitly mentioned in the paper; likely involved standard meteorological instruments and computational tools for data analysis.
4：Experimental Procedures and Operational Workflow:
Data on solar radiation, cloudiness, temperature, and air transparency were collected and compared. Calculations were performed for solar radiation on horizontal and inclined surfaces using specified formulas (e.g., Kastrov and Berlage formulas). Optimal power and payback periods of solar panel plants were calculated based on the recalculated radiation values.
5：Data Analysis Methods:
Statistical analysis was used to compute deviations (e.g., mean-square deviations) and compare results. Economic analysis included calculating payback periods using cost rates and fuel displacement.
