G12R Mono 620W-650W-Bifacial solar panel

620W-650W N-Type TOPCon Bifacial Solar Panel

Ocean Solar AOX-132G12RHC is a high-power 620W-650W N-type TOPCon bifacial dual-glass solar module designed for utility-scale solar plants, commercial and industrial projects, agrivoltaic systems and other large photovoltaic installations where module power, installed DC capacity and rear-side energy generation are important.

The series uses 132 N-type TOPCon half-cut cells in a 6 × 22 configuration and reaches up to 650W front-side rated power with module efficiency up to 24.10%. The module measures 2382 × 1134 × 30mm and weighs approximately 32.5kg.

Its bifacial dual-glass construction allows the rear cell surface to convert reflected and diffuse irradiance into additional electrical output when installation conditions provide sufficient rear-side exposure. A 1500VDC maximum system voltage, -40°C to +85°C operating range and 5400Pa front / 2400Pa rear mechanical-load ratings support large commercial and utility photovoltaic system design.

AOX-132G12RHC Key Specifications

Up to 650W Output and 24.10% Module Efficiency

The AOX-132G12RHC series covers front-side rated power from 620W to 650W. The highest-power version reaches module efficiency up to 24.10%, providing high installed DC capacity per module for large photovoltaic projects.

Higher module power can reduce the number of modules required for a target system capacity compared with lower-wattage products. Depending on the project layout, this can also reduce the number of mounting positions, connectors and module-handling operations.

Actual project savings depend on module price, mounting-system design, tracker configuration, inverter architecture, electrical balance of system, labor and site conditions.

G12R N-Type TOPCon Cell Technology

The AOX-132G12RHC uses N-type TOPCon half-cut cells in a 132-cell, 6 × 22 configuration. TOPCon passivated-contact technology is designed to support high photovoltaic conversion efficiency while reducing carrier recombination losses within the solar cell.

Half-cut cell architecture and multi-busbar interconnection provide multiple current-collection paths and support efficient electrical performance across the module.

For EPC contractors and project developers, cell technology should be evaluated together with module power, dimensions, bifacial performance, electrical compatibility, mechanical loading and total installed system cost.

Bifacial Dual-Glass Solar Module

The AOX-132G12RHC uses a bifacial dual-glass structure designed to generate electricity from direct irradiance reaching the front side together with reflected and diffuse irradiance reaching the rear cell surface.

Actual rear-side contribution varies with installation conditions. Ground reflectivity, roof surface, mounting height, tilt angle, tracker geometry, row spacing, structural members and cable routing can all affect the amount of irradiance reaching the rear side.

For commercial and utility projects, expected bifacial gain should therefore be modeled using site-specific irradiance, albedo and array geometry instead of assuming a fixed percentage increase for every installation.

2382 × 1134mm High-Power Module Format

The AOX-132G12RHC uses a 2382 × 1134 × 30mm large-format module design that combines up to 650W rated power with a standardized rectangular footprint for commercial and utility photovoltaic installations.

Large-format modules can increase the amount of DC capacity installed per module, but system designers should evaluate physical handling, tracker or racking compatibility, module spacing and access requirements before finalizing the array layout.

Each module weighs approximately 32.5kg. Installation planning should therefore consider two-person handling or appropriate lifting methods, site access and the requirements of the selected mounting system.

1500VDC System Design

The AOX-132G12RHC supports a maximum system voltage of 1500VDC according to the published specification, making it suitable for evaluation in large commercial and utility photovoltaic system architectures.

Final modules-per-string calculations must consider the exact module open-circuit voltage, minimum project temperature, inverter maximum DC voltage and applicable electrical requirements.

Module operating current and short-circuit current should also be checked against the selected inverter or central inverter input-current limits before the final string configuration is approved.

Mechanical Load Capability

5400Pa Front-Side Load

The module is specified for a maximum front-side mechanical load of 5400Pa. Final structural capability depends on the approved mounting method, support location, clamp configuration and project-specific snow and structural load requirements.

2400Pa Rear-Side Load

The published rear-side mechanical-load rating is 2400Pa. Mounting rails, trackers, clamps and supporting structures should be selected according to the applicable module installation requirements and local wind-load calculations.

Operating Temperature from -40°C to +85°C

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

System designers should consider local minimum and maximum temperatures during electrical and structural design, particularly when calculating maximum string voltage, selecting inverters and evaluating balance-of-system components.

Applications for 620W-650W Bifacial Solar Panels

Utility-Scale Ground-Mounted Solar Plants

High module power and bifacial generation make the AOX-132G12RHC suitable for evaluation in large ground-mounted photovoltaic plants where module count, mounting-system compatibility, inverter design and rear-side irradiance all influence system economics.

Commercial and Industrial Solar Projects

Commercial and industrial projects can use the high module power to increase installed DC capacity. Roof dimensions, structural capacity, module handling and inverter compatibility should be verified before finalizing rooftop system design.

Agrivoltaic Solar Systems

Elevated agricultural photovoltaic structures can provide useful rear-side exposure while allowing agricultural activities below or between module rows. Array height, spacing, shading and structural layout should be designed for both energy generation and agricultural requirements.

Fishery-Solar and Water-Side PV Projects

Bifacial modules can also be evaluated for elevated fishery-solar and water-side photovoltaic systems where reflected and diffuse irradiance can reach the rear module surface. Structural, electrical and environmental requirements should be reviewed for the specific site.

Desert and High-Irradiance Solar Projects

Large high-irradiance photovoltaic projects can use high-power modules to reduce module quantity for a target plant capacity. Final engineering should consider ambient temperature, dust, wind, surface reflectivity, cleaning strategy and maintenance access.

How to Improve Rear-Side Bifacial Energy Yield

Rear-side energy generation increases when more reflected and diffuse irradiance reaches the back of the module. Light-colored, concrete, gravel or other reflective surfaces can provide more rear-side irradiance than dark low-reflectance surfaces.

Module mounting height, tilt angle and row spacing also affect rear-side exposure. Tracker beams, mounting structures and cables should be positioned to reduce unnecessary rear-side shading where practical.

Project developers should use site-specific albedo, irradiance and array geometry when estimating bifacial gain rather than applying a fixed percentage to every project.

What EPC Contractors Should Confirm Before Ordering

High-power modules should be evaluated as part of the complete photovoltaic system rather than selected only by wattage. Before ordering, EPC contractors should confirm the selected power class, module dimensions, mounting system, inverter configuration and project environmental conditions.

For bifacial projects, site albedo, module height, row spacing, tracker or fixed-tilt geometry and rear-side shading should be included in the energy-yield assessment.

Buyers should also confirm destination-market documentation, required product certificates, warranty documentation, packaging configuration and shipping requirements before tender submission or mass procurement.
