The Role of Solar Shock Absorbers under Current Trends

Driven by the development goals of carbon dioxide emission peak and carbon neutrality in countries around the world, some experts predict that there will be a 115.7billion Chinese market for photovoltaic tracking systems in the next five years, and an estimated 308.5billion Chinese market in the next 10 years. It is the golden opportunity for photovoltaic tracking system industry to make up for its shortcomings.
The previous traditional trackers can only meet the tracking needs of single-sided components, flat ground, and sunny scenes. With the rapid growth of photovoltaic installations, complex terrain and various climatic conditions pose certain challenges to the reliability of tracking brackets and the actual effect of additional issuance. In order to adapt to various weathers，terrains and landforms, to improve energy conversion efficiency, automatic trackers have appeared to keep the sun always shining and placed vertically on the photovoltaic panel, thereby increasing the photovoltaic conversion rate.
Compared with the traditional tracking solution, the tracking solution can operate normally in various harsh environments such as strong wind, blizzard, hail, sand, wind and snow, to ensure the safety of itself and the photovoltaic modules. At the same time, Solar farm equipped with tracker or tracking systems enable PV module turn with the most accurate alignment as the Sun's position shifts and collect optimum sun energy for the longest period of the day and improve power output and lower levelized cost.
However, tracking system is unstable at relatively modest wind speeds. Measures such as external dampers or shock absorbers must be implemented to stabilize the system. The damper is designed with customized damping in extension and compression directions to dissipate wind shock and stabilize solar tracker or tracking system in smooth running.
In conclusion, the customized dampers or shock absorbers with high-quality, diversified configurations will become an indispensable part of the solar tracking system, which can help it reduce wind vibration effectively, stabilize the tracking system, and increase the service life.
