研究目的
To investigate, through experimental tests, the effects of environmental factors such as ambient temperature, wind, rainfall, soiling, pollution, and aging on the power output of a grid connected PV station.
研究成果
The study concluded that the output power and efficiency of PV systems are deeply affected by various environmental factors, which are weather dependent. The findings suggest that in desert regions, the electrical power loss can reach as much as 30% if cumulative losses from aging, seasonal temperature variation, heating effect of solar radiation, and dust and soiling effect are considered. These parameters should be taken into consideration while sizing the system to avoid any deficiencies in the power demand.
研究不足
The study was conducted in a specific geographical and climatic condition (Saharan environment), which may limit the generalizability of the findings to other environments. Additionally, the study focused on a limited set of environmental factors.
1：Experimental Design and Method Selection:
The study involved performance analysis on an experimental grid connected PV system situated at Biskra University, within a semi-arid zone in southeastern Algeria. The test rig consisted of forty 85-Wp PV modules coupled to an INGECON SUN 5.0 inverter. Modules were assembled in 10 panels of four series connected modules each. The PV field was split into two sets of five series connected panels for different tests.

4：0 inverter, and various sensors for solar radiation and temperature.
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: Tests included the effect of pollution under different climatic conditions, the effect of aging on PV panel power output, the effect of seasonal temperatures on PV panel power output, and determinations of grid connected harvested power under clean and polluted PV panels.
5：Data Analysis Methods:
The impact of these parameters on the PV system performance was gauged by a comparison of the current–voltage (I-V) and power–voltage (P-V) characteristics of the panels.
