研究目的
To produce a climatology of the components of the solar radiation field such that regions can be identified in which harvesting diffuse light may contribute substantially to the total output of solar panels and panel arrays.
研究成果
The study presents a comprehensive 15-year climatology of direct and diffuse radiation across the United States, highlighting the importance of tuning solar panel orientation to the local radiation field for maximizing energy yield. It suggests that regions east of the Mississippi River could benefit from strategies that more efficiently harvest diffuse radiation, while regions in the Northwest and Southwest may require adaptive strategies based on large-scale climate signals like ENSO.
研究不足
The study relies on modeled data from the NSRDB, which, while intended to accurately represent long-term statistics, may not capture all nuances of observed data. The spatial and temporal variability of solar radiation and its modulators (cloud cover, AOD) introduces uncertainties in the optimal solar panel orientation strategies suggested.
1：Experimental Design and Method Selection:
The study utilized the National Solar Radiation Database (NSRDB) to analyze the seasonal cycles of solar radiation across individual locations within the US and across eight separate US climate zones. The methodology involved analyzing the direct and diffuse solar radiation, total sky cover, opaque sky cover, and aerosol optical depth.
2：Sample Selection and Data Sources:
Data from the U.S. Department of Energy’s National Solar Radiation Database (NSRDB), which is a high density network of U.S. sites containing modeled hourly radiation data for the 20 year period spanning from 1991 to 2010, were used in this study.
3：List of Experimental Equipment and Materials:
The NSRDB contains statistical summaries of class I and class II stations for the years 1991 to 2005. These statistical summaries contain monthly and annual means of solar radiation (total, direct normal, and diffuse), sky cover at each station, and meteorological variables.
4：These statistical summaries contain monthly and annual means of solar radiation (total, direct normal, and diffuse), sky cover at each station, and meteorological variables.
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The study analyzed the direct and diffuse solar radiation, total sky cover, opaque sky cover, and aerosol optical depth. Both the direct and diffuse radiation are reported in Watt-hours per square meters (Wh/m2).

Data Analysis Methods:
5. Data Analysis Methods: The study involved analyzing the seasonal cycles of solar radiation across individual locations within the US and across eight separate US climate zones. The analysis can be used to determine which areas of the US are best suited for expansion of solar energy development, and which areas might benefit from a combined direct-diffuse harvesting strategy to maximize the harvesting of solar energy using solar panels.
