Dual-Axis Solar Trackers & Rooftop Mounting for Solar EPC Companies: A 1.0MW Case
For an EPC company, a demonstration project on its own site is more than a power station — it is a living showcase to prove quality to future clients. Every panel, every structure and every tracker on display must be a benchmark of reliability and performance.
That is why Heilongjiang New Energy Company chose Zhaori (Shandong Zhaori New Energy Technology Co., Ltd.) to supply the dual-axis solar trackers and roof mounting systems for its 1.0MW flagship demonstration project, built on the company's own green belt and building roofs.
Why an EPC Builds a Demonstration Project on Its Own Site
A demonstration project is an EPC's most persuasive sales tool. Before clients commit, they want to see a real, working installation: how the structure handles wind and snow, how precisely it tracks the sun, how cleanly it was installed. A flagship project on the EPC's own premises gives that proof — which is why the supplier must be the best available.
Why They Chose Zhaori?
The New Energy Company evaluated suppliers on exactly the qualities a showcase demands. Zhaori was selected for a set of distinct advantages:
A dedicated solar tracking manufacturer — Years of export experience focused on trackers and mounting systems, not a sideline product.
Higher yield, proven by design — Dual-axis tracking lifts generation by about 25–30% over fixed mounting, so the showcase delivers visibly more power.
Precision with near-zero operating cost — Time + GPS astronomical control gives tracking accuracy of 0.1°–2° while drawing under 0.02 kWh per set per day.
Engineered reliability for harsh climates — Hot-dip galvanized structures, wind and snow load calculations, and full structural reports, built for northern winters.
One accountable supplier — Tracking mounts, fixed rooftop mounting and ground structures from a single source, with design support, installation guidance and certifications.
For a flagship project that must represent the EPC's own standards, these qualities were not optional — they were the reason for the choice.
The Demonstration Project: One Supplier, Two Mounting Systems
Zhaori supplied both mounting systems that make the showcase complete:
Dual-Axis Solar Trackers on the Green Belt
Dual-axis solar trackers follow the sun's full path in azimuth and tilt, capturing significantly more energy than a fixed array. Structures are hot-dip galvanized on reinforced concrete foundations, engineered for local wind and snow loads with foundations clear of underground cables and piping.
Fixed-Tilt Rooftop Mounting on the Buildings
For the roofs, fixed-tilt roof mounting systems — non-penetrating where possible, ballasted or attached without damaging waterproofing, with per-roof structural checks — add low-cost, low-maintenance base-load generation.
| Site | Capacity | Mounting |
|---|---|---|
| Green belt | 0.6MW | 24 dual-axis solar trackers |
| Building roofs | 0.4MW | Fixed-tilt roof mounting |
| Total | 1.0MW | Hybrid (tracking + fixed) |
What the Showcase Delivers
Annual generation: ≈1.16 million kWh, almost fully self-consumed on site
Annual electricity savings: ≈600,000 CNY under commercial tariffs
Generation uplift on the tracking portion: ≈27% vs. fixed mounting
Investment: rooftop fixed mounting is low-cost; tracking adds only ~10%, while shortening payback by about one year
Beyond the numbers, the project gives JiNeng New Energy a working reference to show every future client — proof that premium engineering pays off.
