Special features

icon-34

Torsional Stability & Sturdiness of the tracker structure

1 pile foundation pillar per 1.6 SPV panels assures highest strength, torsional stability and sturdiness for the solar tracker structure

icon-35

Wind resilience

The ‘gap’ maintained between the two adjacent SPV Panels in our patented design mitigates the wind speed to ensure better wind resilience

icon-36

Avoids stockpiling of snow and sand mass

The ‘independent tiltability’ of each PV Panels in our patented design avoids the stockpiling of ‘snow’ and / or ‘sand’

icon-37

Better safety index

The iTST’s maximum tilt height is kept within the lower wind velocity zone to assure better safety index.

icon-28

Temperature of the Panels

Since there is a provision for free flow of air (wind) between each panels, the temperature of the panels are always kept at the least for better yeild

icon-38

Robot cleaning system usage

iTST’s frame design is best suited to accommodate robot cleaning system

icon-39

Remote monitoring and control

Remote monitoring is customised based on customer requirement

HDAT FAQs

What is Horizontal Dual Axis Tracker (HDAT)?

Horizontal Dual Axis Tracker (HDAT) is the world’s first cost-effective dual-axis solar tracker, designed and constructed in the principle of “Horizontal Primary Dual Axis Tracker (HPDAT)”.

The previous dual-axis tracker was constructed in the principle of Vertical Primary Dual Axis Tracker (VPDAT), which called for a massive structure and large area resulting in high costs and becoming unviable as of today.
