You want foreseeable returns from your solar properties. You also want fewer frustrations in O&M. Trackers can appear like one more relocating component. They can really feel dangerous. Right here’s the truth. Modern tracking lifts energy yield, cuts LCOE, and reduces life time O&M when you choose the appropriate system and run it with self-control.
Understanding Solar Tracking: How it Works and Why It Matters
Solar tracking systems aim PV components at the sun through the day. Single‑axis trackers turn on one axis. Dual‑axis trackers follow azimuth and altitude. Controllers make use of astronomical formulas and sensing unit comments to position components for optimum irradiance. Excellent tracking lessens shading, enhances diffuse light capture, and takes care of wind stow to protect the variety in storms.
What does that mean for return? Independent research studies show single‑axis trackers typically boost energy by around 15 – 25% over repaired tilt. Dual‑axis systems can reach 25 – 35% depending upon latitude and layout Pair trackers with bifacial components and you can press another 5 – 15% from rear‑side gain with the appropriate ground albedo Extra kilowatt‑hours per mounted watt drive down LCOE in utility tasks by about 5 – 10% when the site and design are optimized
SolPath, from Jinwu Xuanhui Technology Co., Ltd., designs smart tracking systems that put these gains within reach. You get shadow‑resistant tracking that reduces row‑to‑row shading. You obtain remote commissioning and over‑the‑air (OTA) upgrades that reduced soft prices. You get controllers, actuators, and placing from a single supply chain for faster delivery and less complex assimilation.
Myth 1: “Trackers are also pricey to justify ROI”
Capital expense bumps really feel terrifying. You respect payback. Yet ROI rests on lifetime energy harvest and overall expense of possession.
- Single‑axis tracking includes 15 – 25% power vs taken care of tilt in several locations – Dual‑axis can deliver 25 – 35% under the best problems – Optimized tracking cuts LCOE by concerning 5 – 10% in utility scale projects
Where does this pencil out? Mid‑latitudes with high DNI. Websites with favorable wind and geotech. Tasks that generate income from every additional kWh via PPA terms or merchant markets. Bifacial components on trackers can improve rear‑side gain for more powerful business economics
ROI Snapshot: Fixed vs Tracking (Illustrative)
| Scenario (100 MWdc) | Energy Gain vs Fixed | Estimated LCOE Delta | Indicative Payback Window |
|---|---|---|---|
| Fixed Tilt Baseline | — | — | — |
| Traceur à axe unique | +15–25% | −5–8% | 4–7 years |
| Traceur à deux axes | +25–35% | −8–10% | 5–8 years |
Figures show market varieties from independent standards Your site determines the final numbers.
SolPath’s value originates from greater than steel and motors. Shadow‑resistant algorithms reduce mismatch losses. Remote appointing trims mount time. OTA updates allow you roll efficiency improvements across the fleet without truck rolls. That combination increases return and reduces soft expenses which reduces repayment.
Actionable steps:
- Model yield with location‑specific TMY data and include bifacial rear‑side assumptions.
- Run LCOE with sensible O&M and extra strategy.
- Validate structural and wind stow design versus neighborhood codes and gust accounts.

Myth 2: “Trackers break down frequently and need consistent upkeep”
Older systems battled. Modern trackers do not. Market information reveals yearly maintenance expenses for today’s trackers commonly rest listed below 1% of initial capex when you use predictive maintenance and smart controls Integrity rises with less complex drive trains, sealed transmissions, and robust controllers.
SolPath trackers make use of closed‑loop comments and astronomical positioning. Systems store in high winds to safeguard structures. Snow‑shedding modes and anti‑shadow regimens enhance accessibility in hard climate. Remote monitoring flags exemptions swiftly. OTA firmware updates deliver solutions and attributes without on‑site job.
O&M Profile: Fixed vs Tracking (Typical Ranges)
| System Type | Annual O&M as % of Capex | Maintenance Focus |
|---|---|---|
| Fixed Tilt | ~0.5–1.0% | Module cleaning and electrical |
| Single‑Axis | ~0.8–1.0% | Lubrication, drive checks, firmware |
| Dual‑Axis | ~1.0–1.2% | Additional joint inspections and calibration |
Varieties show market norms and can vary with website and technique
Finest methods that maintain uptime high:
- Use condition‑based lubrication instead of taken care of timetables.
- Trend motor currents and placement mistake to capture wear early.
- Validate wind stow and healing series every period.
- Standardize extra kits for actuators and controllers.

Myth 3: “Tracking barely improves energy so fixed is fine”
Repaired tilt can serve some sites well. In numerous areas tracking victories emphatically.
- Single‑axis: +15 – 25% energy vs taken care of tilt – Dual‑axis: +25 – 35% energy vs dealt with tilt- Bifacial + single‑axis: an additional +5 – 15% relying on albedo and row spacing
Location matters. Reduced latitudes and clear skies favor tracking. Diffuse environments still profit since controllers can optimize for spread light. Great row spacing and SolPath’s shadow‑resistant tracking decrease inter‑row shading so you harvest a lot more in early morning and late mid-day.
Energy Gain by Approach (Industry Benchmarks)
| Approach | Energy Gain vs Fixed Tilt |
|---|---|
| Fixed Tilt | — |
| Single‑Axis Tracking | +15–25% |
| Dual‑Axis Tracking | +25–35% |
| Single‑Axis + Bifacial | +20–40% total vs fixed (combined) |
Data compiled from independent records Website problems control last gains.

Myth 4: “Trackers are just for large utility projects”
Utility projects lead adoption. That’s true. Smaller sized applications can benefit when problems fit.
- Commercial rooftops with clear spans and architectural capability.
- Ground‑mount commercial behind‑the‑meter sites with time‑of‑use tariffs.
- Agricultural and off‑grid systems that reward afternoon yield.
SolPath offers scalable styles for dispersed generation and particular niche uses. Have a look at Suivi commercial services if your website has ground area. Discover Suivi agricole usage instances for ranches that desire more power in shoulder hours. For resilience in remote websites consider Suivi hors réseau.
Website suitability still rules the choice. You desire adequate troubles, low shading, appropriate wind program, and cost‑effective structures. If those boxes inspect you can warrant tracking outside of utility scale.
Myth 5: “Trackers aren’t eco‑friendly and waste sources”
Trackers add steel and controls. They additionally boost energy per acre which shrinks the land footprint per provided kWh. Higher yield lowers job LCOE. That drop reduces lifecycle exhausts per kWh because manufacturing impacts spread out across more generation Bifacial components boost rear‑side harvest without extra active components
SolPath layouts for longevity and lengthy life span. Controllers get OTA updates which prolong capability without equipment swaps. Shadow‑resistant tracking minimizes inequality which assists maintain modules running closer to come to a head. That indicates better power capture over decades.
