420W high transparency Mono Silicon Solar Panel

420W N-Type TOPCon High-Transparency Solar Panel

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

Unlike conventional opaque photovoltaic modules, the high-transparency design creates open light-transmitting areas between the solar cell zones. This makes the module suitable for selected BIPV, solar canopy, pergola, carport and architectural photovoltaic applications where natural daylight and photovoltaic generation need to be considered together.

The module uses N-type TOPCon half-cut cell technology and a dual-glass structure. Its overall dimensions are 2382 × 1134 × 30mm, with a rated front-side power output of 420W. Ocean Solar specifies a 12-year product warranty and a 30-year extra linear power output warranty.

420W High-Transparency Solar Panel Key Specifications

Note: Glass transmittance and whole-module transparency are different specifications. The final module transparency ratio depends on solar cell spacing and module layout and should be confirmed for each project.

What Is a High-Transparency Solar Panel?

A high-transparency photovoltaic module is designed to generate electricity while allowing part of the incident light to pass through transparent areas of the module. Instead of covering the complete module area with photovoltaic cells, transparent gaps are incorporated into the module layout.

This design creates a balance between electrical output and daylight transmission. Increasing the cell-covered area can increase module power density, while increasing the transparent area allows more daylight to pass through. The optimum layout therefore depends on the architectural and energy-generation requirements of the project.

For BIPV and architectural projects, buyers should specify the required power output, module dimensions, visual appearance and target transparency ratio before final production.

N-Type TOPCon Technology

The 420W high-transparency module uses N-type TOPCon solar cell technology. TOPCon uses passivated-contact cell architecture to reduce carrier recombination and improve photovoltaic conversion performance.

Combined with a half-cut cell configuration, N-type TOPCon technology provides a suitable platform for high-transparency photovoltaic modules where part of the module surface is intentionally reserved for daylight transmission.

Dual-Glass High-Transparency Module Design

The existing Ocean Solar product specification describes this model as a high-transparency dual-glass solar panel. Transparent glass on the module structure allows daylight to pass through the intentionally open areas between the photovoltaic cell zones.

The current product copy specifies high-transmittance tempered glass with glass transmittance above 93%. This value describes the optical transmission performance of the glass itself and should not be interpreted as a 93% whole-module transparency ratio.

For projects requiring a specific amount of natural daylight, the total transparent area, solar cell spacing, installation angle and supporting structure should be evaluated together.

Why Use Transparent Solar Modules in BIPV Projects?

Solar Generation and Daylight in One Building Element

Transparent photovoltaic modules can combine solar electricity generation with partial daylight transmission. This makes them useful where a conventional opaque PV panel would block too much natural light.

Architectural Integration

The visible spacing between photovoltaic cell areas creates a distinctive architectural appearance. Cell spacing and module dimensions can therefore become part of the building design rather than being treated only as electrical equipment.

Custom Light-Transmission Requirements

Different projects may prioritize electricity generation, daylight, shading or aesthetics differently. Customized transparent-area layouts can be discussed according to project requirements, subject to photovoltaic and structural engineering review.

Typical Applications of 420W Transparent Solar Panels

Solar Canopies and Carports

High-transparency modules can be integrated into suitable solar canopies and carports where photovoltaic generation and partial daylight beneath the structure are both required.

Pergolas and Outdoor Structures

Pergolas, walkways and similar structures can use transparent PV modules as a multifunctional building surface, subject to structural, waterproofing and local building requirements.

Building-Integrated Photovoltaics

The dual-glass transparent layout can be considered for selected BIPV applications where photovoltaic modules form part of the visible architectural envelope. Final use as a building element must comply with the required structural and building standards for the project.

Agrivoltaic and Light-Transmitting PV Structures

Projects that require some sunlight beneath photovoltaic modules may consider a transparent module layout. The required transparency, crop-light requirements and PV layout must be evaluated at project level.

Reliability and Outdoor Performance

Ocean Solar's current product description states that the module uses high-transmittance tempered glass, anti-aging encapsulation materials and an anodized aluminium frame. The module is intended for long-term photovoltaic operation across different outdoor environments.

Project buyers should request the current technical datasheet and applicable test reports before system design to confirm electrical parameters, mechanical loading, glass configuration, fire classification and environmental certifications for the destination market.

12-Year Product Warranty and 30-Year Power Warranty

Ocean Solar currently lists a 12-year product warranty for this 420W high-transparency solar panel. The existing product content also specifies a 30-year extra linear power output warranty.

Product warranty and linear power output warranty are different warranty terms and should be displayed separately throughout the product page and marketing materials.

Custom High-Transparency Solar Panels

For architectural photovoltaic projects, Ocean Solar can discuss customized module configurations according to project requirements. Important design parameters can include module size, cell layout, transparent-area ratio, electrical output, glass appearance, frame requirements and connection configuration.

Because increasing transparency normally reduces the area available for photovoltaic cells, the required transparency and target output power should be defined together during project development.

Packaging and International Delivery

Ocean Solar supports international project delivery for photovoltaic modules. Final pallet configuration, container quantity, delivery schedule, Incoterms and project packaging requirements should be confirmed in the commercial quotation before shipment.

Other Ocean Solar Module Options

Ocean Solar also supplies higher-power bifacial dual-glass modules for projects where maximum photovoltaic output is more important than daylight transmission.
