研究目的
Investigating the effect of aerosols on solar irradiance and photovoltaic power production in Santiago de Chile.
研究成果
The study concludes that aerosols significantly reduce solar irradiance and photovoltaic power production in Santiago de Chile, with annual differences in energy output of -7.2% and -8.7% for monocrystalline and amorphous silicon PV technologies, and -16.4% for CPV technology. The findings highlight the need to consider aerosol effects in the design of photovoltaic plants and solar forecasting tools.
研究不足
The study is limited to clear sky conditions and does not account for the effect of soiling on PV modules, which may also contribute to power output losses. Additionally, the spatial distribution of aerosols across Santiago is not fully represented.
1：Experimental Design and Method Selection:
The study uses the SMARTS2 model to estimate the effect of aerosols on solar irradiance, incorporating AERONET sunphotometer data and other in-situ measurements.
2：Sample Selection and Data Sources:
Data were collected between 2014 and 2016 in Santiago de Chile, including solar irradiance measurements, aerosol data, and atmospheric measurements.
3：List of Experimental Equipment and Materials:
Instruments used include CMP21 Kipp and Zonen pyranometer, CHP1 Kipp and Zonen pyrheliometer, and a SOLYS2 Kipp and Zonen two-axis sun tracker.
4：Experimental Procedures and Operational Workflow:
Solar irradiance components were measured every second and averaged every minute, with quality control applied to filter erroneous data.
5：Data Analysis Methods:
The study uses statistical techniques to analyze the difference in solar irradiance and PV power output between actual conditions and a hypothetical no-AOD case.
