When Typhoon Strikes: Can Your Solar Tracker "Stand Firm"?

From wind‑condition sensing to attitude protection, AITRACKER builds multi‑level intelligent wind‑resistance strategies "Doksuri", "Gaemi", "Mu‑ge"… In recent years, severe typhoons have continuously put coastal and offshore PV power stations to the test.

Strong winds, heavy rainfall and communication fluctuations may all compromise the safe operation of solar trackers.

For tracking systems, the key is not to "wait for the wind", but:

Can wind‑speed variations be detected in a timely manner?

Can active adjustments be made when wind force intensifies?

Can rapid protection be triggered upon anomalies?

These are the core focuses of AITRACKER's intelligent wind‑protection strategy.

Three‑Tier Wind‑Protection Strategy for Active Response to Strong Winds

Targeting different wind conditions, AITRACKER establishes three sets of strategies: Standard High‑Wind Protection, Graded High‑Wind Protection and Forked High‑Wind Protection.

It boosts wind‑resistance response capability step‑by‑step via real‑time sensing, active adjustment and pre‑emptive positioning.

01｜Standard High‑Wind Protection

Detect wind direction and face modules into wind actively

When wind speed exceeds the preset threshold, the system adjusts modules to the pre‑defined wind‑facing protection angle according to real‑time wind direction to mitigate wind load on the array.

FA21 senses wind conditions → NCU executes strategy judgement → TCU performs actions → tracker adjusts attitude

Once wind speed drops back within the safe range, the system automatically resumes normal tracking.

02｜Graded High‑Wind Protection

Step‑wise response to reduce frequent movements

For rapid wind‑speed fluctuations during typhoons, the system supports multi‑level wind‑speed thresholds and gradually narrows the tracker’s operating range as wind speed rises.

The above parameters can be configured according to tracker structure and local meteorological conditions.

Generate power under mild winds; activate progressive protection under strong winds.

03｜Forked High‑Wind Protection

Pre‑emptive positioning to shorten protection travel distance

For horizontal single‑axis solar trackers, combined with astronomical algorithms, the system drives trackers into a preset range close to the protection angle in advance.

When wind speed rises further, trackers can quickly shift into the final protective attitude.

Instead of reacting only after wind arrives, the trackers get into position beforehand.

Full‑Cycle Protection: Pre‑Typhoon, During‑Typhoon and Post‑Typhoon

Pre‑Typhoon | Advance Preparation

Remotely verify wind‑protection strategies and status of sensors & control devices to ensure system readiness.

During Typhoon | Active Protection

The system triggers corresponding protection strategies based on real‑time wind conditions and automatically adjusts tracker attitudes.

Post‑Typhoon | Rapid Review

Check operational status of each row of equipment via Tracker‑SCADA, identify abnormalities and assist O&M personnel in prioritizing inspection tasks.

Protection extends from individual units to risk management for the entire power plant.

Project Deployment in Complex‑Environment Sites

Zeyang Intelligence tracking systems have been deployed in PV projects across diverse climates, terrains and operating environments.

Selected projects: 

50 MW Project in Danyang, Jiangsu

30 MW Fish‑PV Complementary Project in Wujiang

Sicily Project, Italy

Tarsia Project, Italy

Rich project experience accumulated across diverse environments underpins long‑term stable operation of tracking systems.

Typhoons Are Inevitable, Yet Risks Can Be Managed in Advance

Covering wind‑condition sensing, strategy decision‑making, attitude execution and post‑typhoon review, AITRACKER implements a multi‑level intelligent wind‑protection system.

It enables trackers to get ready before gales hit,

respond actively as winds pick up,

and recover rapidly once winds subside.
