How to Choose a Solar Tracker Unit


What kind of solar tracker device to use

There are two main types of solar trackers on the market: single-axis and dual-axis.

Single-Axis Sun Tracker: Track the sun from east to west, rotate at one point, move synchronously by solar panel or by section.

Dual-Axis Tracker: Rotates on the X and Y axes to make the panel track the sun directly.

Single-axis tracker tracking technology is not new to the solar market, with single-axis solutions becoming the standard for utility-scale applications. Compared to dual-axis trackers, single-axis trackers harvest less energy per unit, but with shorter shelf heights, they require less installation space, creating a more concentrated system footprint and components that are easier to operate and maintain.

How to Choose a Solar Tracker Unit

Here are some factors to consider when choosing a solar tracker unit:

Reliability: Choose a tracker that has been proven for a long time and has reliable performance.

Accuracy: Choose a tracker that can precisely track the sun's movement to ensure maximum solar harvesting.

Cost: Consider the cost of the tracker as well as the cost of installation and maintenance.

Adaptability: Choose a tracker that can adapt to different environmental conditions, such as deserts, plains, mountains, etc.

Durability: Choose a tracker that can withstand extreme weather conditions, such as windstorms, rain, snow, etc.

Environmental protection: Choose a tracker that has less impact on the environment, such as low energy consumption, low noise, etc.

To sum up, choosing a suitable solar tracker device requires comprehensive consideration of the above factors and making a decision based on the actual situation.

What type of solar tracker unit to choose

Which type of solar tracker unit to choose depends on specific needs and environmental conditions.

Manual Solar Tracker: Requires someone to physically adjust the panels at different times of the day to follow the sun. Not practical, requiring someone to constantly monitor the sun and change the position of the solar panel system.

Passive Solar Tracker: Contains a low-boiling liquid that will evaporate when exposed to solar radiation. When the liquid evaporates, the tilt system becomes unbalanced. This imbalance causes the panels to tilt in the direction of the sun's rays.

Active Solar Trackers: Rely on motors or hydraulic cylinders to change position. Motors in the active tracker will move the photovoltaic panels so they face the sun.

Therefore, when selecting a solar tracker device, it is necessary to select a suitable tracker type according to specific needs and environmental conditions. For example, when it is necessary to improve the power generation efficiency of the photovoltaic system, an active solar tracker device with higher precision and better reliability can be selected.
