Photovoltaic Power Generation

Photovoltaic power generation is use solar cell transfer the light power to electrical energy. The photovoltaic power generation system is constitute with solar cell, storage cell,controller and inverter, solar cell is one of the key component, the solar cell component need rotate by tracking solar from up and down, left and right, to get more generated power.

LYNBC could supply the worm and gear(slewing drive), slewing bearing with external gear teeth, which can ensure anti-rust and continuous long time operation. Such a field involves some right bearings support, which not only exists slewing rings, but also consists of angular contact roller bearings, track rollers/Yoke type track rollers and spherical plain bearings.

Importance of Bearings in PV Systems

Solar Tracking Systems:

Single-Axis Trackers: These systems rotate the solar panels along one axis (usually north-south) to follow the sun's movement from east to west. Bearings are used at the pivot points to allow smooth rotation.

Dual-Axis Trackers: These systems adjust the panels along two axes (both north-south and east-west) to maximize solar exposure. Bearings are critical at both axes to ensure precise movement.

Load Support: Bearings support the weight of the solar panels and the structural components of the tracking system, ensuring stability and reducing wear and tear.

Reduction of Friction: By minimizing friction, bearings help in reducing the energy required to move the panels, thereby increasing the overall efficiency of the PV system.

Durability and Longevity: High-quality bearings can withstand environmental factors such as dust, moisture, and temperature variations, ensuring long-term reliability and reducing maintenance costs.

Applications of Bearings in PV Systems

Rotation Mechanisms: Bearings are integral to the rotation mechanisms of solar trackers, ensuring smooth and precise movement to follow the sun's path.

Structural Support: They provide support to the structural components of the PV system, ensuring stability and reducing the risk of mechanical failure.

Drive Systems: Bearings are used in the drive systems that move the solar panels, ensuring efficient energy transfer and reducing wear on moving parts.

Maintenance and Reliability: High-quality bearings reduce the need for frequent maintenance, ensuring the long-term reliability of the PV system.

Bearings are indispensable components in photovoltaic power generation systems, particularly in solar tracking systems. They ensure smooth operation, reduce friction, support structural loads, and enhance the overall efficiency and durability of the system. Understanding the types and applications of bearings in PV systems is crucial for designing and maintaining efficient and reliable solar power installations.
