How can you maintain solar tracking systems for optimal performance?

1 Types of solar tracking systems

There are two main types of solar tracking systems: active and passive. Active systems use motors, sensors, and controllers to move the solar panels or mirrors according to a programmed algorithm or a feedback signal from the sun. Passive systems use a fluid-filled cylinder that expands and contracts due to the temperature difference between the sunny and shady sides of the system, causing the panels or mirrors to tilt. Active systems are more precise and reliable, but also more complex and costly. Passive systems are simpler and cheaper, but also less accurate and efficient.

2 Maintenance procedures

The maintenance procedures for solar tracking systems vary depending on the type, size, and location of the system. However, there are some general steps that should be taken to maintain most systems. It is important to inspect the system regularly for signs of wear, corrosion, cracks, loose connections, or dirt accumulation. Additionally, the panels or mirrors should be cleaned with a soft cloth and water or a mild detergent. Avoid using abrasive or harsh chemicals that can damage the surface or reduce the reflectivity. Moving parts such as bearings, gears, chains, or pistons should be lubricated with a suitable grease or oil according to the manufacturer's instructions and specifications. Test the system's functionality and accuracy by checking the alignment, rotation, and tracking of the panels or mirrors with a digital inclinometer, a compass, or a sun tracker app. Any faulty or damaged components should be repaired or replaced as soon as possible; if major repairs or adjustments are needed, contact a qualified technician or service provider.

3 Common issues and solutions

Solar tracking systems can enhance the performance of solar power systems by capturing more sunlight and generating more electricity. However, common issues that can affect their performance include obstructions, weather, electrical problems, and mechanical issues. To prevent these issues, choose a site with a clear view of the sun, install sensors to trigger a safety mode during extreme weather conditions, install surge protectors or circuit breakers to prevent power overloads, and lubricate the system's moving parts regularly. Additionally, check the wiring and connections for any loose or frayed wires, adjust the system's balance and weight distribution regularly, and tighten the bolts and nuts as needed. With proper maintenance, you can ensure optimal performance of your solar tracking systems.
