Typically, there are 2 types of dual-axis trackers based on altitude- a) Tip-tilt: To track the sun’s position, they can tilt in both the east-west (azimuth) and up-down (altitude) directions. b) Azimuth-altitude: These dual-axis solar trackers allow solar panels to move in 2 directions azimuth (east-west) and altitude (up-down).
Open loop tracker: It is also a type of active tracker that can operate without feedback control mechanisms. Instead of using real-time sensor feedback, it moves solar panels using pre-calculated calculations or algorithms. It is further divided into two subtypes 4. Passive Tracking Devices
This type of tracker is great for flat areas of land that usually stay dry and sunny. Now, let’s explore the various types of single-axis trackers such as vertical, horizontal, tilted, and polar aligned. a) Horizontal Single-Axis Solar Tracker (HSAT): This one rotates from east to west on a fixed axis that is parallel to the ground.
There are two main types of dual-axis trackers: Polar-Axis Trackers and Altitude–Azimuth Trackers. Polar-axis tracking, also called spinning-elevation tracking, refers to dual-axis solar trackers that rotate panels along one vertical axis and one horizontal east-west axis. This axis is similar to the path the sun traces in the sky.
No. Upgrading a residential solar panel system already installed with fixed-tilt mounts to a dual-axis tracker system is generally not feasible or cost-effective for three main reasons. These reasons are structural incompatibility, mounting challenges, and cost considerations.
Yes, dual-axis tracking leads to substantially higher solar energy production compared to fixed-tilt systems. A fixed-tilt system typically refers to a solar panel installation where solar panels are fixed at a specific angle, facing south, and set in a stationary position.
