<\/div>\n\n\n\n

Vertical solar trackers have long held great potential but have been limited by high costs and sensitivity to strong winds. With VajaTrack, we have solved both problems. Through patented wind-responsive technology, VajaTrack delivers higher energy production, lower structural loads, and a robust solution developed for Nordic conditions. <\/p>\n\n\n\n

Developed to produce more valuable solar electricity<\/h2>\n\n\n\n

VajaTrack is the result of several years of development with a clear goal \u2013 to produce more valuable solar electricity.

By combining smart mechanics, robust design, and optimized algorithms, we have developed a solar tracker system that delivers higher energy production and better profitability than traditional ground-mounted solar installations.<\/p>\n\n\n\n

Unique feathering mechanics<\/h3>\n\n\n\n

Panels protect themselves against the wind<\/h2>\n\n\n\n

At the core of Vaja’s solar tracker system is feathering mechanics <\/em>– a mechanism that allows the solar panels to feather passively. During strong winds, the panels automatically, smoothly, and quickly lift to a nearly horizontal position. This occurs without motors \u2013 the panels are lifted solely by the force of the wind, thanks to a design that carefully utilizes aerodynamic principles.<\/p>\n\n\n\n

Because the panels naturally move to their stable position during high winds, the wind load is reduced by more than 85% compared to a fixed panel in a traditional vertical solar tracker, and by 80% compared to a panel locked at a 30-degree tilt (common for fixed mounting systems and for horizontal solar trackers in “stow mode”).<\/p>\n\n\n\n

Vaja’s feathering principle resembles how leaves on trees and bushes in nature have evolved to survive strong winds: by swaying flexibly instead of resisting with brute strength \u2013 the exact opposite of how traditional solar mounting structures and solar trackers function.<\/p>\n\n\n\n

Minimal torque design<\/h3>\n\n\n\n

Lower load ensures longer lifespan<\/h2>\n\n\n\n

Vertical solar tracker systems rotate around their vertical axis to follow the sun and thereby maximize electricity production. In Vaja’s design, this rotation is also used to achieve an architecture with minimal torque design<\/em> that works in conjunction with the feathering mechanics to protect the structure.<\/p>\n\n\n\n

On rare occasions with very strong winds, the units rotate around their vertical axis to optimize their orientation toward the wind instead of toward the sun. This minimizes torque, which further reduces structural loads, reduces stress and wear on the drivetrain and motor, and helps prevent situations where the wind might otherwise cause harmful resonance. <\/p>\n\n\n\n

Altogether, the minimal torque design contributes to a long lifespan with minimal maintenance, as well as durability even in extreme weather.<\/p>\n\n\n\n

Centralized drive system<\/h3>\n\n\n\n

Fewer motors result in lower costs<\/h2>\n\n\n\n

Traditional vertical solar trackers use one motor per tracker unit, which significantly increases both cost and complexity.<\/p>\n\n\n\n

Vaja’s passive feathering mechanics and minimal torque allow the rotation of many tracker units to be driven by a cable-based centralized drive system<\/em>.<\/p>\n\n\n\n

With a single motor, one gearbox<\/strong>, and one control module<\/strong> driving many tracker units, both investment costs and ongoing maintenance are significantly reduced.<\/p>\n\n\n\n

Share avoidance optimization<\/h3>\n\n\n\n

Maximizes production from every panel<\/h2>\n\n\n\n

Vaja’s vertical solar tracker system employs several strategies to significantly reduce shading between units within the solar park \u2013 including optimized hardware design, carefully planned solar park layouts, and backtracking algorithms specifically adapted for vertical solar tracking.<\/p>\n\n\n\n

The result is minimal shading losses, ensuring that the inherently higher energy production of vertical solar trackers at latitudes beyond the 30\u00b0 latitude is actually achieved in practice.<\/p>\n\n\n\n
