STR-22G Sun Trackers:

A Sun Tracker, also known as a solar tracker, is a device that is used to orient a solar panel or reflector towards the sun. This is done to maximize the amount of energy that can be produced by the solar panel or reflector. One example of a sun tracker is the STR-22G, which is a single-axis tracker that is designed for use in residential and commercial solar systems.

The STR-22G is a robust and durable sun tracker that is capable of withstanding wind speeds and snow loads. It is also built to be corrosion-resistant, which is an important consideration for outdoor use. The tracker features an easy-to-use and intuitive control system that allows for simple setup and operation.

The STR-22G can support solar panels, depending on the wattage and size of the panels. The tracker’s mechanism uses a sensor to detect the sun’s position, and an actuator to move the solar panels so that they are always facing the sun. This allows for more efficient energy production, as the solar panels are able to capture more energy throughout the day.

The STR-22G also come with several advanced features, such as automatic self-diagnostics, and can also be controlled remotely via a web-based interface. Additionally, it come with safety features such as automatic shut down in extreme weather condition.

Overall, the STR-22G is a reliable and efficient sun tracker that is suitable for use in residential and commercial solar systems. Its robust construction, easy-to-use control system, and advanced features make it an ideal choice for maximizing energy production.

The compact 2-arm STR-22G sun tracker is perfectly suited to support all kinds of Global, Diffuse, and Direct Radiation measurement sensors. Besides the standard EKO sensor mounts, various alternative mounts for non-EKO sensors are available. Featuring a fully automated set-up procedure via an onboard GPS receiver, providing increased reliability and enhanced functionality, the compact Sun-Tracker guarantees accurate sun tracking and pointing of the attached solar sensors from sunrise to sunset.

The 2-axis tracker automatically adjusts to the sun’s position by the sun sensor closed-loop control system, even if the tracker is not oriented or leveled properly. The sun-tracker comes standard with a small table tripod (larger tripod available). The 24 VDC low-power consumption tracker can be powered by a solar-powered battery system or DC power supply. A wide range of AC power adapters can be supplied to connect to the grid.

For over 20 years, clients who have deployed STR sun-trackers have enjoyed easy set-up, smooth operation, and reliable tracking.
