Tier 1 Brand, 730W-750W Mono Bifacial Dual-Glass Solar Module

730W-750W HJT Bifacial Dual-Glass Solar Panel

The CHN-750W-HC-DG is a 730W-750W high-power HJT bifacial dual-glass solar module designed for utility-scale, commercial and industrial photovoltaic projects. The series combines 132-cell large-format module architecture with 2.0mm + 2.0mm glass construction and delivers up to 750W front-side rated power.

Module efficiency ranges from 23.50% to 24.10%, while the -0.24%/°C Pmax temperature coefficient supports stronger power retention as module temperature rises. The bifacial design can also utilize rear-side reflected irradiance when installed in an appropriate elevated and reflective environment.

The module measures 2384 × 1303 × 33mm, weighs approximately 36.5kg and supports a maximum system voltage of 1500VDC. It uses an IP68 junction box with three bypass diodes and is specified for up to 5400Pa snow load and 2400Pa wind load.

CHN-750W-HC-DG Key Specifications

730W-750W Electrical Characteristics

The following front-side electrical ratings are specified under Standard Test Conditions with 1000W/m² irradiance, 25°C module temperature and AM1.5 spectrum.

Electrical Performance Under NOCT

NOCT data provides a more representative reference for module behavior under operating conditions of 800W/m² irradiance, 20°C ambient temperature and 1m/s wind speed.

Why HJT Technology Matters for High-Power Solar Projects

-0.24%/°C Pmax Temperature Coefficient

Solar module output decreases as cell temperature increases. The CHN-750W-HC-DG has a specified Pmax temperature coefficient of -0.24%/°C, helping limit temperature-related power loss in high-temperature operating environments.

This characteristic is particularly relevant to utility and commercial projects in high-irradiance regions where module temperatures can remain well above the 25°C STC reference temperature during peak generation periods.

Strong Low-Light and Bifacial Potential

HJT architecture is commonly selected for projects that prioritize temperature performance and bifacial generation. With transparent rear glass, the module can collect reflected irradiance reaching the rear cell surface.

Actual bifacial energy gain is site-specific and depends on albedo, mounting height, row spacing, tilt angle and rear-side shading. Project yield should therefore be modeled using actual installation conditions rather than a fixed percentage.

2.0mm + 2.0mm Bifacial Dual-Glass Construction

The module uses 2.0mm anti-reflection coated front glass and 2.0mm high-transparency rear solar glass. The dual-glass structure protects the encapsulated solar cells from both sides while allowing rear-side irradiance to contribute to photovoltaic generation.

The current product datasheet also states environmental testing for salt mist, ammonia corrosion, sand blowing and PID resistance, making the module relevant to projects that require additional environmental durability assessment.

Mechanical Strength and Outdoor Reliability

5400Pa Snow Load

The module datasheet specifies resistance to a maximum tested snow-side load of 5400Pa. Final mounting design must follow the installation manual, local structural calculations and the required safety factor.

2400Pa Wind Load

The specified rear-side mechanical load is 2400Pa. Clamp position, tracker compatibility and mounting-system engineering should be confirmed for each project.

IP68 Junction Box

An IP68-rated junction box with three bypass diodes provides outdoor electrical protection and supports module operation when localized shading affects part of the photovoltaic circuit.

Aluminum and Steel Frame Project Options

The current CHN-750W-HC-DG datasheet specifies an anodized aluminum frame. The existing Ocean Solar product page also describes a steel-frame project option. If a steel-frame version is required, its weight, coating, mechanical load rating and packaging configuration should be confirmed separately in the project quotation.

1500V System Design for Large PV Projects

The module supports a maximum system voltage of 1500VDC and a maximum series fuse rating of 35A, making it suitable for appropriately designed high-voltage commercial and utility-scale strings.

Final modules-per-string calculations must consider module Voc, the minimum project design temperature, inverter maximum DC voltage, MPPT current limits and applicable electrical codes.

Applications of 730W-750W HJT Bifacial Solar Panels

Utility-Scale Ground-Mounted Solar Farms

Up to 750W front-side module power can reduce the number of modules required for a given DC capacity compared with lower-wattage modules. This can influence mounting quantity, electrical connections, handling and installation productivity at large project scale.

Single-Axis Tracker Systems

The large-format bifacial module can be evaluated for compatible tracker projects. Tracker structural compatibility, module clamp zones, wind-load requirements and electrical current limits should be confirmed during system design.

Commercial and Industrial Solar Projects

High module power can be valuable for large commercial and industrial projects where developers want to maximize installed capacity and reduce module count. Roof structural capacity must be evaluated because the module is approximately 36.5kg.

Agrivoltaic and High-Albedo Projects

Bifacial modules can benefit from rear-side reflected irradiance in suitable agrivoltaic, desert, light-colored ground and elevated mounting environments. Actual bifacial gain should be calculated from project-specific albedo and array geometry.

Manufacturing and Quality Control

High-power HJT modules require consistent control of cell inspection, interconnection, encapsulation, lamination and electrical performance. Module quality control can include incoming-material inspection, EL electroluminescence inspection, flash testing, insulation testing and final visual inspection before packaging.

The current product datasheet states that the modules undergo full-piece EL inspection as part of production quality control.

Certification and Project Documentation

The current product materials reference photovoltaic quality, safety and environmental testing. Buyers should request the latest certificates applicable to the exact module model and destination market before project approval or tender submission.

Packaging and International Delivery

The current datasheet specifies 34 modules per packaging unit and approximately 612 modules per 40-foot container. Actual loading quantity should be reconfirmed with the commercial quotation because packaging configurations may vary by frame, cable and project requirements.

Optional configurations shown in the current datasheet include original MC connectors, 1200mm cable length, black frame and black glass. Availability should be confirmed before order placement.

12-Year Product Warranty and 30-Year Linear Power Warranty

The current CHN-750W-HC-DG datasheet specifies a 12-year product warranty and a 30-year linear power warranty. These should be displayed as two separate warranty terms rather than describing the module simply as having a 30-year product warranty.

The published linear warranty curve shows approximately 99.0% warranted power after year 1, 96.3% at year 10 and 90.3% at year 30, subject to the applicable warranty document and contractual terms.
