Key highlights

Gain, computed.

30 % Annual energy gain Dual axes track the sun all day; typical value versus fixed-tilt plants, varying with latitude and irradiance. 80 % O&M labour cost Cloud-based remote monitoring and diagnostics keep site crews small and flag faults early. 60 % Lifetime LCOE Software and hardware are co-optimised from siting models to daily operation, lifting project IRR. ±0.5° Tracking accuracy Roughly 2–4× the common industry level; the gap widens most in early-morning and late-afternoon light. 25 years Design life Structure, drive and control are engineered for the full lifecycle, with automatic stow posture in extreme weather.
Application scenes

Wherever the sun goes, the array follows.

From mountains to islands, from farmland to business parks — one solar tracking racking covers the main terrains.

Mountainous terrain · Follows the slope
Mountainous terrain · Follows the slope Rugged terrain, still squared to the sun. Slope and orientation adapt automatically so every module faces the light.
Off-grid island · Diesel to solar
Off-grid island · Diesel to solar Off the grid, still a steady daytime supply. Working with storage, it widens the off-grid power window.
Agrivoltaics · Two yields per acre
Agrivoltaics · Two yields per acre Power above, farming below. Pile foundations take little ground, so generation and cultivation coexist.
Business park · Install and go
Business park · Install and go Install it on the green and go. The column-mounted design blends naturally with the surroundings.

  1. A "—" means the item does not apply to that model, or must be issued separately against the approved project drawing and structural calculation report; ratings and dimensions are model-specific.
  2. DC nominal capacity is derived from the module count and module power in this table; it is not an instantaneous guaranteed output, nor does it equal annual energy yield.
  3. Class 12 is a design rating under the specified protective posture, project foundation and installation conditions, and does not mean normal operation in Class 12 winds; mechanical damping is dynamic cushioning, not static load bearing, and does not add up to a wind-resistance rating.
  4. Dimensions are in mm; specifications on this page are subject to the final order and project documents.
