Solar Linear Actuator Application

Solar energy is an excellent renewable energy source that has become increasingly popular in recent years. Solar linear actuator is a high-tech product, in recent years due to the explosion of solar power generation projects, solar electric actuator also followed the heat up. This article looks at how to use linear actuators to enhance solar tracking and improve solar energy production.

Linear actuator basis

Linear actuators are devices that convert electrical energy into linear motion. They include components such as motors, transmissions, lead screws or ball screws, and position feedback devices. Electric actuators come in various types and sizes. The most common types are linear and rotary actuators. Linear actuators are used where linear motion is required. They are commonly used in solar tracking systems.

Fundamentals of solar tracking systems

A sun tracker is a device that ensures that the solar panel follows the position of the sun throughout the day, so that the main optical axis of the solar collector is always parallel to the sun's rays, and when the sun's rays are tilted, the sensor outputs a tilt signal. This signal is amplified and sent to the control unit, which begins to work and instructs the linear actuator to adjust the solar collector until the solar collector is aligned with the sun.

The benefits of linear actuators in solar tracking

Commonly used photoelectric tracking devices are: gravity photoelectric tracking device, electromagnetic photoelectric tracking device, electric photoelectric tracking device. These photoelectric tracking devices all use photosensitive sensors, such as silicon photocells, which are close to the shading plate and are positioned so that the shading plate is aligned with the sun, and the silicon photocells are in the shadow area. In contrast, linear actuators have several advantages. First, they are more energy efficient, which reduces operating costs. Second, because there are fewer moving parts, they are low maintenance and have a long service life. Third, electric actuators are environmentally friendly and do not emit harmful gases like hydraulic systems. Finally, electric actuators are precise and provide accurate positioning, leading to better solar panel performance.

Application of linear actuator in sun tracking

The solar energy automatic tracking device is used to track the sun, so that the main optical axis of the energy collector is always parallel to the sun rays. Linear actuators are commonly used in solar tracking systems to move solar panels in straight lines. They are used in single-axis and dual-axis solar trackers. Linear actuators are also used in other solar applications such as solar panel tilting, solar panel cleaning systems, and solar mounting brackets.
