Therefore, it is necessary to continuously improve and innovate the production process of PV systems; such improvements and innovations can not only enhance the cleaning performance and carbon emission reduction capacity of PV systems, but can also alleviate any worries associated with building a large number of new PV systems.
Several atmospheric conditions can affect the output of solar PV systems. This section considers five factors: clouds, pollutants, humidity, dust, and wind speeds. 4.1. Cloud characteristics Cloud cover strongly impacts solar PV output, primarily by reducing the Direct Normal Irradiance (DNI) received [90, 91].
All PV systems experience performance degradation over their lifetime which leads to reduced energy output [, , ], in common with other renewable technologies .
Therefore, the true environmental impact of solar PV is a rapidly moving target: as deployment increases, further research and development is incentivized, in turn improving efficiency, resource use, and other parameters that determine its life cycle impacts.
Studies that have considered other LCA categories have suggested that solar PV can have considerably higher impacts—sometimes by several orders of magnitude—than conventional electricity technologies, including nuclear power and natural gas.
