700W Heterojunction (HJT) Ultra-High-Power Solar Module for Mega Solar Projects

The 700W Heterojunction (HJT) Ultra-High-Power Solar Module represents a quantum leap forward in photovoltaic efficiency. HJT technology seamlessly fuses the best qualities of crystalline silicon and amorphous thin-film silicon. The result is a module that effortlessly crosses the 700W threshold, boasting conversion efficiencies exceeding 22.5%. It is the definitive choice for mega solar projects where maximizing energy output per square meter is critical.

Key Advantages & Benefits

  • Record-Breaking Efficiency: Achieves massive power density, drastically reducing the Levelized Cost of Energy (LCOE) and Balance of System (BOS) costs.
  • Best-in-Class Temperature Coefficient: Outstanding performance in hot climates; power output barely drops as ambient temperatures soar, far outperforming standard PERC panels.
  • Exceptional Bifaciality: Can achieve up to 90% bifaciality, meaning the rear side is nearly as efficient as the front, generating vast amounts of extra power from ambient scattered light.
  • No Light Induced Degradation (LID): HJT cells suffer zero LID, ensuring your power plant operates at its absolute peak from day one.

Versatile Applications

  • Utility-scale mega solar power plants
  • Space-constrained industrial rooftops
  • High-albedo environments (snowy or sandy regions) to maximize bifacial gain
  • Floating solar farms

Frequently Asked Questions (FAQ)

  • What is the difference between HJT and TOPCon? Both are highly advanced cell technologies. HJT generally offers a slightly better temperature coefficient and higher bifaciality compared to TOPCon, making it exceptionally good in hot and highly reflective environments, though manufacturing costs are slightly higher.
  • Are special inverters needed for a 700W panel? Due to the high current and voltage characteristics of a 700W panel, you must ensure that your string inverters or microinverters are rated to handle ultra-high-power modules.

FAQ

What aluminum alloys do you use to make motorcycle engine cases?

We mainly use high-performance aluminum alloys such as ADC12 and A356. The ADC12 is ideal for complex shapes such as side covers due to its excellent flow properties, while the A356 is the first choice for structural parts such as crankboxes that require excellent strength and elongation. We use a spectrometer to confirm the composition of each melt to ensure material stability.

How to ensure the tightness of the engine cover and prevent oil leaks?

Preventing leaks is the core standard we ensure. We control internal density through precise high or low pressure casting parameters. After casting, we perform precision CNC machining on the sealing surfaces and perform pneumatic leak tests on the oil passages and water passages to ensure zero leaks in the assembly.

How long is the delivery lead time for OEM motorcycle engine covers

For new OEM projects, the lead time from mold design to T1 sample delivery is typically 35-50 days. Once samples are approved, our capacity of 5000 tons per year allows us to adjust mass production plans to meet your specific delivery deadlines

What surface polishing options do you provide for motorcycle engine case covers?

Our process includes Shot Blasting and vibration deburring to achieve a clean, matte appearance. At the same time, we can also prepare powder coated or painted surfaces based on the aesthetic requirements of your brand.

Application Background and Use Scenario

Heat Pipe R&D and Sample Preparation


Heat pipe development requires stable and repeatable sample-level processing before entering mass production. During R&D stages, engineers need precise control over heating, degassing, and welding preparation to verify product structure and process feasibility. This equipment is designed to support such sample preparation tasks under controlled conditions.


Process Validation Before Mass Manufacturing


Before scaling up to full production lines, manufacturers often need to confirm welding parameters, heating lengths, and degassing performance. This machine provides a practical platform for process validation, helping reduce risks during later mass production deployment.


Integrated Heating and Degassing Process


The heating process is controlled by both temperature and time, allowing operators to set parameters according to different pipe diameters and material requirements. This helps maintain consistent thermal conditions during sample processing.
