FAQ

A solar tracking racking supports the PV array so that it actively follows the sun in both azimuth and tilt. Fixed racking never moves and only receives light at its optimal tilt; a single-axis tracker moves in one direction only; a dual-axis system moves in both, staying squared to the sun through the day.
The HELIO² range covers three model tiers: TG-8 V3 (single-column, 8-module class), TG-24 (single-column, 24-module class) and SZGZ-X (rectangular format, 8-16 mounting positions configurable). Tracking range is azimuth ±180° rotation with tilt 0-70° swing (SZGZ-X: tilt 0-85°; actual software limits depend on the delivered version). Both axes are driven independently, and azimuth and tilt operating ranges can be set separately. The quotation covers the tracker only and excludes PV modules.

Tracking is driven by the HELIO² SmartTrack™ 3.0 algorithm: astronomical calculation combined with edge computing, supported by BeiDou / GPS / GLONASS positioning, plus real-time correction from local irradiance and weather data, so tracking continues under overcast diffuse light. Combined tracking accuracy is ±0.5°.
Against a fixed-tilt plant, the typical annual energy gain is 30% (the series ledger records 30-40%), varying with latitude, irradiance and module configuration. Cloud-based remote monitoring and diagnostics also cut O&M labour cost by a typical 80%. These are typical values, not guaranteed figures; project figures follow local irradiance data.

The racking is engineered for extreme-weather conditions and the datasheet states the boundary: a wind rating of operating class 10 / protection class 12+. Once project-defined protection conditions are reached, normal tracking stops and protective action is executed. Under snow conditions the tilt is adjusted per project strategy and snow is shed automatically. Electrical components are wide-temperature rated with three-level lightning protection, and each SZGZ-X axis has a DC gear motor with automatic locking on power loss.
Protection thresholds are set per project, and the values actually delivered follow the project technical documents. Weather beyond the design standard can still cause damage: the design margin reduces this risk substantially but cannot remove it. The structure is designed for a 25-year life.

Estimate: annual yield ≈ installed capacity × annual equivalent full-load hours × (1 + tracking gain). Take TG-24: 17.76 kWp DC (24 × 740 W modules). With peak sun hours taken as 4 h/day (an illustrative assumption here - use the project site irradiance data in practice), that is about 1,460 equivalent full-load hours a year: roughly 25,930 kWh with fixed mounting, and about 33,700 kWh at a 30% tracking gain.
Actual output also depends on module wattage, latitude and weather, and real irradiance in mountainous or hazy regions can be well below the example. Send us the site coordinates, installed capacity and intended module model, and we can run the numbers on local irradiance data.

Four main terrain scenarios: mountainous plants (slope and orientation adapt automatically so every module faces the light), off-grid islands (working with storage to widen the off-grid window), agrivoltaics (pile foundations take little ground, so generation and cultivation coexist) and urban parks (column-mounted, blending with the surroundings). The ledger also records commercial and industrial distributed projects, demonstration PV projects, public space, and utility-scale or complex terrain.
On foundations: the quotation covers the tracker only, while foundations, anchors and motion clearance are defined by the confirmed project drawings and local engineering conditions. SZGZ-X offers column heights of 2.1 m or 2.6 m; TG-8 V3 and TG-24 are single-column designs with few piles and flexible pile spacing for sloping ground and agrivoltaic sites.

We supply distributors, EPC contractors, installers and project developers, with an integrated service covering product selection, system configuration, technical documentation and certification files through commercial quotation and export logistics to remote technical support. Exports are organised in 20 ft container formats. Documentation for the tracking range is available in EN and CN (datasheets, brochures, installation and commissioning manuals, after-sales and O&M manuals) on the Downloads page, so site installation and commissioning can follow the manuals, with remote technical support and spare-parts coordination from us.
The quotation covers the tracker only; PV modules, foundations, inverters, cabling, civil works and approvals are project scope. Delivery boundaries and the responsibility matrix are stated in the quotation and contract, and the specific division of work and schedule follow the contract.

Yes. Configurable at specification level: module position count (SZGZ-X supports 8-16), column height, operating ranges and software limits (azimuth and tilt set separately), operating strategies (12 operating strategies · 9 operating states), and monitoring accounts and enabled features. Module outline, mass, clamping zone and the racking interface must be confirmed together with the racking, and foundations, anchors and motion clearance follow the confirmed project drawings.
Non-standard requirements can be assessed at proposal stage: send us the project conditions (site, module model, installed capacity, grid requirements) and our engineering team will work up a customised proposal.
