Solar tracking systems are automated systems that dynamically adjust the tilt of solar panels to the movement of the sun, so that they are always at an optimal angle to the sun. This technology significantly increases the efficiency of solar panels , allowing you to maximize energy yield.
How does the solar tracking support structure work?
Sun tracking: The sun tracking system uses sensors to track the position and movement of the sun. The system automatically rotates the solar panels so that they are always at the most favorable angle to the sun's rays.
Types:
Single-axis solar trackers: Move the solar panels along a north-south or east-west axis. A simpler and more cost-effective solution. Typically provides a 15-20% increase in performance compared to fixed systems.
Dual-axis solar trackers: Track the sun's movement along both the north-south and east-west axes. They provide maximum efficiency, with up to a 25-30% increase in power output.
Energy efficiency
The use of sun tracking systems is particularly beneficial in areas with a high number of sunshine hours and a wide range of sun path variations throughout the seasons.
Advantages
Increased energy yield: They can produce up to 25–30% more energy than fixed solar systems.
Quick payback: The initial investment may be higher, but the increased energy production will pay for itself faster.
Environmentally friendly: Their additional energy production reduces energy dependence and contributes to sustainability.
Adaptation to changes in solar radiation: They optimize energy production by following the position of the sun, regardless of the season or time of day.
Disadvantages
Higher investment cost: Due to the more complex structure and technology of solar tracking systems, they can be more expensive than fixed systems.
Maintenance requirements: Automated mechanisms may require regular maintenance to ensure smooth operation.
Larger space requirements: Moving parts and dual-axis systems may require more space for installation.
Examples and calculations
Single-axis system: A 10 kW solar system can produce approximately 3,000–4,000 kWh more energy per year than a fixed system.
Two-axis system: The same system can generate up to 4,500–5,500 kWh more energy per year, which can result in significant savings in electricity costs.
Summary
Solar tracking supports are an innovative solution to increase the efficiency of solar systems. Although the initial costs may be higher, the long-term savings and increased energy yield make these systems particularly attractive for larger projects.
