420W high transparency Mono Silicon Solar Panel

420W N-Type TOPCon High-Transparency Solar Panel

Ocean Solar 420W high-transparency solar panel is an N-type TOPCon dual-glass photovoltaic module designed for projects that require both solar electricity generation and controlled daylight transmission through the module.

Unlike conventional opaque photovoltaic modules, the module incorporates transparent areas between photovoltaic cell zones. This allows part of the available daylight to pass through while the solar cells generate electricity.

The module provides 420W rated front-side output and measures 2382 × 1134 × 30mm. Its N-type TOPCon half-cut cell architecture and transparent dual-glass construction make it suitable for selected BIPV, solar canopy, pergola, carport and architectural photovoltaic projects.

420W High-Transparency Solar Panel Specifications

Glass transmittance and whole-module transparency are different specifications. The >93% value refers to the light-transmission performance of the transparent glass material. Actual module transparency depends on the photovoltaic cell coverage, spacing and module layout.

What Is a High-Transparency Solar Panel?

A high-transparency photovoltaic module generates electricity while allowing part of the incident daylight to pass through transparent areas of the module.

Crystalline silicon solar cells are opaque. Transparency is therefore created by arranging the photovoltaic cells with controlled spacing and leaving selected areas of the dual-glass module transparent.

Increasing photovoltaic cell coverage can increase available module power, while increasing the transparent area allows more daylight to pass through. The correct balance should therefore be selected according to the energy-generation, daylight and architectural requirements of each project.

N-Type TOPCon Solar Cell Technology

The 420W high-transparency module uses N-type TOPCon photovoltaic cell technology combined with a half-cut cell configuration.

TOPCon passivated-contact technology provides a high-performance crystalline silicon platform suitable for transparent photovoltaic designs where part of the total module area is intentionally reserved for daylight transmission.

Dual-Glass High-Transparency Module Design

The module uses a transparent dual-glass structure that allows daylight to pass through intentionally open areas between photovoltaic cell zones.

High-transmittance tempered glass with a specified glass transmittance above 93% is used in the transparent module structure.

The glass transmittance value should not be interpreted as the transparency percentage of the complete photovoltaic module. Whole-module transparency is determined by the proportion of transparent glass area remaining after the solar cells and electrical components are arranged within the module.

Solar Generation and Daylight in One Module

Controlled Daylight Transmission

Transparent areas allow natural light to pass through the module, making it possible to combine photovoltaic generation with partial daylight beneath or behind the installation.

Architectural Integration

The visible spacing between photovoltaic cells can become part of the architectural design. This is useful for projects where a conventional opaque module would block too much daylight or would not provide the desired visual effect.

Project-Specific Transparency

Projects can require different balances between solar output, shading, daylight and appearance. Module layout and transparent-area requirements can be discussed according to the final architectural and photovoltaic design.

Typical Applications of 420W Transparent Solar Panels

Solar Canopies and Carports

High-transparency modules can be incorporated into compatible solar canopies and carports where photovoltaic generation and partial daylight beneath the roof are required.

Pergolas and Outdoor Structures

Pergolas, walkways and similar structures can use transparent photovoltaic modules where the design requires both shading and controlled light transmission.

Building-Integrated Photovoltaics

The transparent dual-glass design can be considered for selected BIPV applications where photovoltaic modules form part of the visible architectural envelope.

Use of the module as an architectural or structural building element must be evaluated against the required glass configuration, mounting system, mechanical loads, fire requirements and applicable building regulations.

Agrivoltaic and Light-Transmitting PV Structures

Projects that require part of the available sunlight to reach the area beneath the photovoltaic installation can consider a transparent cell layout. The required daylight level and photovoltaic output should be evaluated together at project level.

How Transparency Affects Solar Power Output

Transparent crystalline photovoltaic modules require a balance between solar cell coverage and transparent glass area.

A module with more photovoltaic cell coverage generally provides more active generating area. A module with wider spacing between cells provides more transparent area and allows additional daylight to pass through.

Buyers specifying a custom transparency requirement should therefore define the desired daylight transmission and required photovoltaic output together rather than treating transparency and power as independent parameters.

Custom High-Transparency Solar Module Design

Ocean Solar supports project-based discussions for customized transparent photovoltaic module configurations.

Important project parameters can include module dimensions, photovoltaic cell arrangement, transparent-area ratio, target electrical output, glass appearance, frame requirements and electrical connection configuration.

When a specific transparency level is required, the target transparency and required module output should be evaluated together before the final module layout is confirmed.

Frequently Asked Questions About 420W High-Transparency Solar Panels

What is a 420W high-transparency solar panel?

It is a photovoltaic module that combines 420W rated solar output with transparent areas that allow part of the daylight to pass through the module.

What solar cell technology is used?

The module uses N-type TOPCon half-cut photovoltaic cells.

What are the dimensions of the 420W solar panel?

The specified module dimensions are 2382 × 1134 × 30mm.

Is the complete solar panel more than 93% transparent?

No. The >93% specification refers to the transmittance of the high-transmittance glass material. Whole-module transparency is lower and depends on solar cell coverage, cell spacing and the transparent-area layout.

How is transparency created in a crystalline solar module?

Crystalline silicon cells are opaque. Transparent areas are created by leaving controlled spaces between the solar cells and cell groups so daylight can pass through the dual-glass module.

Can the transparency level be customized?

Project-specific transparent-area layouts can be discussed. The required transparency, desired photovoltaic output, module dimensions and cell arrangement should be defined together before final production.

Does higher transparency reduce solar panel power?

Increasing transparent area generally leaves less module area available for photovoltaic cell coverage. Transparency and required power output should therefore be evaluated together when selecting a custom module layout.

Is the 420W transparent solar panel suitable for BIPV?

The transparent dual-glass construction can be considered for selected BIPV applications. The final project must also meet the applicable structural, glazing, fire, mounting and local building requirements.

Can it be used for solar canopies and pergolas?

Yes. Transparent photovoltaic modules can be considered for compatible canopies, pergolas, carports and similar structures where both electricity generation and partial daylight are required.

Can the module be used for a photovoltaic carport?

It can be considered for suitable photovoltaic carport designs. The supporting structure, fixing method, glass requirements and mechanical loads should be confirmed for the specific project.

Is this 420W module bifacial?

The available product information confirms a transparent dual-glass structure and N-type TOPCon technology but does not provide a verified bifaciality value for this model. Rear-side power contribution should therefore be confirmed before it is included in system yield calculations.
