670W 210R Rectangular Wafer Solar Panel

670W 210R Rectangular Wafer Solar Panel | High-Density PV Module

The 670W 210R Rectangular Wafer High-Density Utility Solar Panel capitalizes on the latest industry shift toward rectangular silicon wafers. By moving away from traditional square formats, this module maximizes active cell area within standard container dimensions, significantly improving power packing density and reducing logistical shipping costs for multi-megawatt solar farms.

Key Advantages & Benefits

Optimized Dimensions: Rectangular 210mm-format wafers reduce wasted dead space between cells, boosting overall module efficiency.
Lower Balance of System (BOS): Higher wattage per panel means fewer modules, fewer mounting structures, and reduced installation labor.
Superior Container Utilization: Designed for exact alignment inside standard 40-foot high-cube shipping containers, lowering transport carbon footprint.
High Mechanical Strength: Robust frame design handles wind and snow loads effortlessly in large open-field environments.

Versatile Applications

Utility-scale ground-mounted solar power plants
Large-scale desert solar farms
Industrial tracking systems (Single-axis trackers)

Frequently Asked Questions (FAQ)

Q: What is a 210R rectangular wafer?
A: It is an evolution of the standard 210mm round-cornered wafer, cut into a rectangular shape to maximize surface area utilization and string voltage matching.
Q: Are these panels compatible with standard single-axis trackers?
A: Yes, they are engineered with standard mounting hole spacing to fit seamlessly onto all major single-axis tracker brands.

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.
