Regardless of whether it is a standard electric linear actuator, a small-sized actuator, or even a micro actuator, these devices have seen strong development and application across various industries. One common aspect of their use is their significant role in the renewable energy sector. Here, we will focus on the development of electric actuators in the field of photovoltaic (PV) power generation.
1. Reasons for Applying Electric Actuators in the Photovoltaic Industry
The idea of using electric actuators in PV systems emerged due to the high cost of solar panels, which greatly limited the widespread adoption of such products. Under these circumstances, there was a strong need for alternative products, leading to further development of electric actuators.
2. Development of Electric Actuators in the PV Industry
From the early stages of technology to the present day, photovoltaic power generation has evolved from expensive solar cells to more cost-effective polycrystalline silicon cells, with a significant expansion in application fields. During this process, the use of components has also changed. In the past, fixed brackets were mostly used in power generation systems. However, the current trend has shifted toward actuator-based tracking systems.
3. Recognition of Electric Actuators in the PV Industry
Due to the high efficiency and stability of actuator-based tracking systems, they have received widespread recognition from both the government and industry peers. This has further encouraged investment in this area, ushering in a promising period of development for electric actuator tracking systems.
4. Categories of Electric Actuator-Based PV Tracking Systems
This power generation model can be broadly classified into two main types: single-axis linked tracking systems and dual-axis tracking systems. Regardless of the type, electric actuators serve as the driving force for these tracking systems. Because of this, strict requirements are placed on their service life—they must match the lifespan of the solar panels in order to maximize the overall efficiency of the PV power generation system.
