What is it about?
This paper investigates different methods of determining the optimum tilt angle (OTA) for photovoltaic (PV) systems to maximize energy yield, and provides an evaluation index system for the static and dynamic performance of PV systems under hazy weather conditions, in view of the nature of solar energy resource and PV energy yield.

Why is it important?
In recent years, the rapid economic expansion and urbanization has led to worsening air pollution and more frequent occurrence of hazy weather, especially in major cities of China. The culprit of hazy weather is fine particulate matter (PM) pollution of atmospheric aerosol, and it is largely responsible for the severe poor visibility. The influence of aerosol loads on solar irradiance is complicated.The analyzed method for small difference between isotropic and anisotropic models can be used with observation data from other big cities of China.The validation of up to date tilt radiation models in a high turbidity area would be interesting.
Perspectives
Writing this article was a great pleasure as it is that I have long been engaged in. This article also lead to me contacting meteorological service and to attracting more attention in solar energy and PV power research under hazy weather conditions.
