- Flat Single Axis Solar Trackerrotate from east to west to track the sun everyday.The elevation angle is 0 degree. It is the mainstream tracking solution for ground-mounted PV power stations at present.
- Core Advantages
- Significant Power Generation Improvement
- Annual power output increases by 10%–25%compared with fixed brackets; the figure can exceed 25% in regions with abundant solar irradiance and moderate latitudes.
- Panels actively track the sun throughout the day, tilting upward in the morning and laying flat in the afternoon, which greatly boosts the reception of vertical irradiation, with the most prominent gain during low-light periods at dawn and dusk.
- The extra power revenue can offset most incremental investment compared with simple fixed brackets.
Sunchaser Flat Single Axis Solar Tracker can be 1p and 2p.
- Wide Applicability and Strong Compatibility
- Applicable to flat land, gentle slopes with gradient ≤10%, tidal flats, agrivoltaic and fishery-PV complementary projects.
- Compatible with monocrystalline/bifacial double-glass and large-size modules. When paired with bifacial modules, extra backside irradiation further lifts power gains.
- Matches string inverters and central inverters for large-scale power stations with high standardization.

- Lower Civil Work Cost and Better Land Utilization than Tilted Single-Axis & Dual-Axis Trackers
- The horizontal spindle keeps brackets low, requiring shallow foundation pits and less concrete, leading to far lower civil construction costs than tilted single-axis and dual-axis trackers.
- Neat array layout with controllable row spacing and moderate land coverage ratio, occupying less land than dual-axis trackers.
- Low bracket height reduces wind load and lowers the difficulty of wind resistance structural design.
- Moderate O&M Difficulty and Mature Reliability
- Equipped with only one set of driving assemblies (motor + reducer/electric push rod), far fewer moving parts than dual-axis trackers.
- Over a decade of industrial application; tracking algorithms, motors and bearings are standardized with well-documented failure modes and universal spare parts.
- Simple mechanical structure allows direct passage of automatic cleaning robots.
- Integrated intelligent control: astronomical algorithm linkage with light sensors; panels automatically lay flat and lock under strong winds for protection on cloudy days.
- Superior Levelized Cost of Electricity (LCOE)
- The incremental investment per watt is much lower than that of dual-axis trackers.
- Stable power generation gains deliver optimal economic performance for large and medium-sized ground stations in Northwest, North and East China.
- Mass procurement continuously cuts unit prices of brackets and electric control systems, further improving cost performance.
- Friendly for Agrivoltaic Integration
- Uniform and spacious under-panel space with consistent height; the horizontal spindle does not block inter-row sunlight.
- Suitable for planting low-growing cash crops and forage grass, and accessible to agricultural machinery.
