How are solar tracking systems classified?

Solar tracking systems are classified based on their motions into: As its name implies, a single-axis solar tracker rotates around one axis. For instance, these trackers are typically aligned in the north-south direction, allowing them to follow the sun’s east-to-west movement.

How do solar tracking systems work?

These tracking devices typically feature sensors and operate based on complex algorithms that allow them to determine the sun’s relative position depending on the location’s latitude and longitude, time of the day and orientation of the collector. Solar tracking systems are classified based on their motions into:

What is a solar tracker?

Ground mounted solar installations can use solar trackers to tilt the angle of solar panels throughout the day, maximising generation. They are typically used in large scale commercial or utility projects - not residential - as they come with added setup and maintenance costs, due to the additional moving equipment.

Do solar tracking systems cost more than a fixed array?

All solar tracking systems will cost more money up front than a fixed array, due to the complexity of the technology. With moving parts, they come with added maintenance costs. It’s also worth noting that due to the weight of the equipment, they are too heavy for most roofs, so are only suitable for mounting on the ground.

What is a single axis solar tracker?

As its name implies, a single-axis solar tracker rotates around one axis. For instance, these trackers are typically aligned in the north-south direction, allowing them to follow the sun’s east-to-west movement. Alternatively, they may be aligned with the east-west direction to track the sun’s movement along the north-south direction.
