Photovoltaic panels solar trackers

What is a photovoltaic solar tracker?

A photovoltaic solar tracker is a mechanical device to rotate PV panels to achieve an optimal angle concerning the sun 's rays. The greater the perpendicular alignment with the sun's rays, the greater the efficiency. For this reason, installing solar panels with a photovoltaic tracker improves the performance of the electrical energy output.

Are solar trackers used in solar panel systems?

Solar trackers could be included in both types of solar power systems; however, concentrated solar power is used for large power plants, while solar panels are installed for residential and commercial use. Our discussion here focuses on solar trackers used in solar panel systems.

Are solar trackers better than fixed-tilt solar panels?

Consequently, solar panels equipped with solar trackers provide higher system output compared to fixed-tilt ground-mounted solar power systems. Fun fact: The first solar tracking systems were installed on the solar panels of orbiting satellites. On the other hand, a solar tracker system will likely cost more upfront than a fixed solar panel system.

What are solar tracking systems?

Implementing modern technology, solar tracking systems have become more robust and technologically complex. Solar trackers now include anemometers, solar sensors, GPS units, and other sensors that integrate with Geographical Information System (GIS) software.

How much does a solar tracker cost?

Solar trackers are not cheap, so their benefits need to be weighed against their cost. Depending on the arrangement of the trackers and the size of the system, a single-axis tracking system can add $500 to $1,000 per panel to the entire system cost. A dual-axis system can double the cost of the entire project.

What are the different types of solar tracking systems?

There are two types of solar tracking systems based on their movement: single-axis and dual-axis. A single-axis tracker moves your panels on one axis of movement, usually aligned with north and south.
