The differences between solar tracking systems and solar fixed systems

In the construction of photovoltaic power stations,the selection of the solar energy support system directly determines the power generation efficiency and long-term returns of the power station.Currently,the mainstream equipment on the market can be divided into two categories:solar tracking systems and solar energy fixed systems.Many users often struggle to decide which system to choose when building a photovoltaic power station.In fact,the overall structure,applicable scenarios,and service life of the two systems have very little difference.The core difference lies in the aspect of power generation efficiency,and the key factor causing the difference in power generation volume is whether a professional solar energy tracker is installed.

The solar energy fixed system is the commonly used configuration for traditional photovoltaic power stations.After the equipment is installed,the inclination angle and orientation of the solar panels will be permanently fixed and cannot be adjusted according to the position of the sun.During daily sunlight,only during the noon period can the solar panels receive vertical direct sunlight.In the early morning,evening,and during the changes in solar altitude angles in different seasons,the angle of light reception by the photovoltaic panels will deviate,resulting in a large amount of light resource waste.This is the core reason why the fixed system's power generation volume is always limited.This system's advantages are simple structure,low cost,and convenient later maintenance,making it suitable for small-scale household photovoltaic power stations and simple power generation scenarios with uniform lighting conditions.

In contrast,the greatest advantage of the solar tracking system is to significantly increase the power generation of photovoltaic modules.This is also the core reason why it is widely selected in industrial and commercial photovoltaic projects.This system is equipped with high-performance solar energy trackers,which can accurately capture the sun's movement trajectory in real time and automatically adjust the angle and orientation of the photovoltaic panels according to the sunrise,sunset,and seasonal changes,allowing the solar panels to always maintain the optimal inclination angle throughout the day,maximizing the absorption of solar energy resources,and completely improving the low utilization rate of light in the fixed system.

Different types of solar energy tracking supports on the market are suitable for different scenarios and have significant differences in power generation gains.Common single-axis solar energy tracking supports can increase the power generation by 20%-30%,while dual-axis solar energy tracking supports have higher accuracy and can increase the power generation by up to 35%-45%.Compared with the fixed support system,the power generation efficiency has achieved a qualitative leap.For industrial and commercial photovoltaic power stations with large areas and the pursuit of long-term high returns,as well as large-scale ground power stations,installing a solar energy tracking system is an extremely cost-effective choice.

Apart from the core difference in power generation efficiency,there is no significant difference between the two photovoltaic systems.Both adopt mature photovoltaic modules and protective structures,have basic performance such as wind resistance,rain protection,and corrosion resistance,are suitable for outdoor complex environments,and have basically the same service life.The maintenance process and fault troubleshooting methods are also highly similar.

In conclusion,the core of the selection of the two systems depends on the user's power generation requirements and budget.Those who pursue low cost and simple installation can choose the fixed system;those who want to maximize the utilization of light resources,increase long-term power generation volume and returns,can install a solar energy tracking system with a professional solar energy tracker.With high-quality solar tracking supports,this is a more advantageous professional solution.
