Mexico - 1.3 mwp single axis solar tracker

Project Overview

A 1.3 MWp (Megawatt-peak) single-axis solar tracker project in Mexico represents a mid-sized utility or industrial-scale renewable energy installation. While 1.3 MWp is considered a smaller capacity compared to massive 100+ MW utility plants, it is a significant size for industrial self-generation or "distributed generation" projects in the Mexican market.

The Challenge

• Wind and Structural Risks: High-velocity wind gusts can cause "galloping" or torsional instability in tracker rows. Unlike fixed-tilt systems, trackers require advanced wind-stow strategies. Relying on active sensors and grid power for stowing can lead to energy losses or failures; passive mechanical stow technologies are increasingly used to mitigate these risks.
• Terrain Constraints: Trackers generally require flat land for optimal performance. While Mexico has vast solar resources, uneven or sloped terrain requires custom foundations and site preparation, which can increase upfront installation costs by 10%–20%.
• Operational Maintenance: Trackers have moving parts (motors, bearings, gears) that are subject to wear. In dusty or high-heat regions of Mexico, this necessitates a more rigorous and costly O&M schedule compared to fixed-tilt installations to ensure the expected 25-year lifespan.

Our Solution

We supplied our advanced Independent Single Axis Solar Tracking System, perfectly tailored for this challenging environment.

To address the uneven terrain, our tracking system utilized a highly adaptable articulated driveline and adjustable foundations, entirely eliminating the need for expensive earthworks. For maximum stability against winds in Gulf of Mexico, the torque tubes and mounting brackets were secured using our heavy-duty, hot-dip galvanized carbon steel U-bolts and foundation anchors.

Furthermore, the system is equipped with an AI-driven backtracking algorithm to prevent row-to-row shading during early morning and late afternoon hours.
