Photovoltaic power plants are energy systems that are affected by environmental factors and the power generated varies during operation due to environmental factors. Project location, installation direction and tilt angle affect the power generation of the power plant.
Therefore, we need to choose well the site where the photovoltaic power plant will be installed. Regarding how to choose, the project needs specific analysis and design due to various factors such as site selection, installation direction and tilt angle.
Project site selection
Take the fixed installation, the fixed installation is influenced by the latitude and longitude of various regions. As latitude increases from high to low, the optimal tilt angle changes.
Compared to the total radiation in the horizontal plane, the total radiation in the oblique plane is higher in high-latitude regions.
Conclusions: For the same total horizontal radiation, greater power generation in higher latitude regions can be greatly increased by using different installation angles in different seasons;
In low latitude regions, using different installation angles in different seasons does not cause much variation in power generation.
Installation Direction
It is usually installed directly to the south and the angle of inclination of the installation is usually equal to the local longitude and latitude or varies by a few degrees.
As a result of the tests, optimal fixed tilt installations increased radiation by 17% to 30% compared to the monitoring systems, while the dual-axis monitoring system increased radiation by 35% to 43%.
Inclination angle
The tilt angle should closely follow the installation direction and be adjusted according to the seasons. After all, the sun angle is different in different seasons.
In order to maximize the power generation efficiency, it is also necessary that the PV modules can capture the sun and collect energy, and the tilt angle should be adjusted in a timely and effective manner.
Furthermore, factors affecting system efficiency such as line loss, component efficiency and maintenance level should also be considered, which will affect the overall power generation efficiency of the photovoltaic system.
By improving our understanding, we hope to help you solve your questions about photovoltaic power generation.
