AOX-66G12HC Key Specifications

Up to 750W Front-Side Power

The AOX-66G12HC series covers front-side rated power from 730W to 750W. The highest-power version reaches published module efficiency up to 24.10%, supporting high installed DC capacity in large photovoltaic arrays.

Increasing module-level power can reduce the total number of modules required for a specified project capacity. Depending on the system architecture, fewer modules can also reduce mounting positions, electrical connections and module-handling operations.

Project economics should be evaluated at system level, including module pricing, mounting or tracker configuration, inverter selection, cable design, labor, land utilization and logistics.

What Is HJT Solar Cell Technology?

HJT, or heterojunction technology, combines crystalline silicon with thin passivation layers to form a high-efficiency photovoltaic cell architecture.

The AOX-66G12HC uses an N-type HJT cell platform together with half-cut cell architecture. This combination is intended for high-power photovoltaic applications where module efficiency, energy yield and long-term electrical performance are important purchasing considerations.

HJT technology is also widely used in bifacial module designs because both front-side and rear-side irradiance can contribute to photovoltaic generation when the module is installed with sufficient rear exposure.

132 Half-Cell Large-Format Module Design

The AOX-66G12HC uses 132 half cells arranged in a 6 × 22 configuration. Half-cell module architecture divides the electrical circuit into smaller cell sections and supports efficient current collection in high-power modules.

The module measures 2384 × 1303 × 33mm, placing it in the large-format photovoltaic module category. It is intended primarily for professional projects where high module power and system-level installation efficiency are more important than compact residential-module dimensions.

At approximately 36.5kg per module, handling procedures, lifting requirements, tracker or racking compatibility and installation access should be considered during project planning.

Bifacial Energy Generation

The bifacial module design allows solar cells to generate electricity from direct irradiance reaching the front surface together with reflected and diffuse irradiance reaching the rear surface.

Actual rear-side contribution depends on installation conditions. Ground albedo, module mounting height, tilt angle, tracker or racking structure, row spacing and rear-side shading all influence the amount of irradiance reaching the back of the module.

Bifaciality and actual annual bifacial energy gain should not be treated as the same value. Project developers should use site irradiance, surface reflectivity and actual array geometry when estimating rear-side contribution.

HJT Modules for High-Temperature PV Projects

Module temperature is an important factor in photovoltaic system performance because solar-cell output changes as operating temperature rises and falls.

HJT technology is commonly selected for high-power projects where temperature performance is an important design consideration, including high-irradiance and hot-climate installations.

For precise project simulations, EPC contractors should use the temperature coefficients from the latest approved AOX-66G12HC technical datasheet together with local irradiance and ambient-temperature data.

1500VDC System Compatibility

The published maximum system voltage is 1500VDC according to the stated IEC specification. This allows the AOX-66G12HC to be evaluated for high-voltage DC string architectures commonly used in large commercial and utility photovoltaic plants.

Final string length must be calculated using the exact module Voc from the applicable technical datasheet, minimum expected site temperature, inverter maximum DC voltage and the permitted MPPT operating-voltage range.

Module operating current, short-circuit current and maximum series fuse requirements should also be checked against the selected inverter and electrical protection design before final approval.

Mechanical Load Performance

5400Pa Front-Side / Snow Load

The current product specification lists a maximum front-side or snow-load value of 5400Pa, equivalent to approximately 550kg/m².

Final structural capability depends on the approved mounting configuration, support positions, tracker or racking system and project-specific snow-load requirements.

2400Pa Rear-Side / Wind Load

The published rear-side or wind-load value is 2400Pa, equivalent to approximately 244kg/m². Racking, trackers and support structures should be engineered according to local wind conditions and the applicable mounting instructions.

-40°C to +85°C Operating Range

The published module operating-temperature range is -40°C to +85°C, with a nominal operating cell temperature of 45±2°C.

Site temperature should be included in both electrical and structural design. Low-temperature conditions are particularly important when calculating maximum string open-circuit voltage, while high operating temperatures influence module power and annual energy yield.

Applications for 730W-750W HJT Bifacial Modules

Utility-Scale Solar Power Plants

The high rated power and large-format module architecture make the AOX-66G12HC suitable for evaluation in utility-scale ground-mounted photovoltaic plants where reducing module quantity and optimizing system-level installation efficiency are important.

Desert and High-Irradiance PV Projects

High-power HJT modules can be evaluated for desert and high-irradiance projects where temperature behavior, dust, wind conditions, ground reflectivity and maintenance strategy must be considered together.

Commercial and Industrial Solar Systems

Commercial and industrial installations can use high-power HJT modules where the roof structure, mounting system, module-handling method and inverter specifications are compatible with the 2384 × 1303mm large-format module.

Agrivoltaic Projects

Elevated agrivoltaic structures can provide useful rear-side irradiance while maintaining agricultural space below or between module rows. Module height, row spacing and shading should be designed to balance photovoltaic generation with agricultural use.

Fishery-Solar and Water-Side PV

The bifacial design can also be evaluated for fishery-solar and other elevated water-side photovoltaic installations where reflected and diffuse irradiance can reach the rear module surface.

Designing for Bifacial Energy Gain

Rear-side generation depends primarily on the amount of reflected and diffuse irradiance reaching the back of the module. Higher-reflectance surfaces generally provide more useful rear-side irradiance than dark surfaces.

Increasing module clearance can improve rear-side exposure. Tilt angle, row spacing, tracker structure, mounting beams and cable routing should also be considered when reducing rear-side shading.

EPC contractors should use project-specific irradiance, albedo and actual array geometry when estimating bifacial energy contribution rather than applying a fixed additional-output percentage to every installation.

HJT or TOPCon: What Should Project Buyers Consider?

Both HJT and TOPCon are N-type photovoltaic technologies used in high-efficiency solar modules. Selection should be based on the complete project rather than technology name alone.

Project buyers should compare rated module power, watts per square meter, temperature behavior, bifacial performance, module dimensions, weight, inverter-current compatibility, warranty terms, certification requirements and delivered project cost.

For HJT projects, verified temperature coefficients, bifaciality data and long-term degradation values are particularly useful when completing detailed energy-yield and financial modeling.
