Risen 475W N-Type TOPCon Bifacial Black Fixed Solar Panel

The Risen 475W N-Type TOPCon Bifacial Solar Panel combines high-efficiency cell technology with a dual-glass bifacial construction to get more energy from the available installation area.

With a module efficiency of 23.8%, a strong -0.29%/°C temperature coefficient and excellent low-light performance, it's a great option for larger off-grid systems, rural properties, marine installations and fixed solar arrays where dependable generation throughout the day matters.

Unlike a conventional single-sided solar panel, the Risen can also generate energy from reflected light reaching the rear of the module. In the right installation, that gives you the opportunity to harvest energy that would otherwise be lost.

High-Efficiency N-Type TOPCon Solar

The Risen 475W uses N-Type TOPCon cells to achieve an impressive 23.8% module efficiency, allowing a substantial amount of power to be generated from its 1762 × 1134mm footprint.

N-Type TOPCon technology also offers lower long-term degradation and strong performance as light levels change throughout the day.

With excellent low-light and partial-shade performance, the Risen 475W TOPCon panel continues to produce useful energy through changing conditions, making it a strong choice for installations where consistent full sun isn't always possible.

Better Performance in Hot Conditions

Solar panels naturally lose some output as cell temperature rises, which makes the temperature coefficient particularly important in Australian conditions.

The Risen has a Pmax temperature coefficient of just -0.29%/°C, helping it retain more of its rated output as panel temperatures increase during hot weather.

For exposed rooftops, sheds, rural properties and off-grid installations that regularly see high summer temperatures, that's a worthwhile advantage.

Bifacial Solar Generation

The Risen's bifacial construction allows both sides of the module to contribute to energy production.

While the front surface captures direct sunlight, the rear cells can make use of light reflected from the ground, roof, water or other surrounding surfaces.

Risen specifies an 80 ±5% bifacial factor. This describes the rear side's relative electrical performance compared with the front of the panel and should not be confused with an automatic 80% increase in total solar production.

Actual rear-side gain depends heavily on mounting height, panel spacing, surface reflectivity, installation angle and shading.

Up to 523W Equivalent with 10% Rear-Side Gain

Under conditions where the rear of the panel contributes an additional 10% irradiance, Risen specifies an equivalent output of approximately 523W.

The panel itself remains rated at 475W under standard front-side test conditions, but the bifacial construction provides the opportunity for additional real-world energy generation when the installation allows sufficient reflected light to reach the rear cells.

This makes mounting design particularly important when you want to take full advantage of bifacial technology.

A Great Option for Marine Solar

Bifacial technology can be particularly interesting in suitable marine installations.

Sunlight reflected from the water and light-coloured deck surfaces can reach the rear of an elevated panel, providing the opportunity for additional generation that a conventional monofacial module cannot capture.

Marine environments also involve constantly changing sun angles and intermittent shade from masts, antennas and other equipment. Combined with its strong low-light performance, the Risen 475W is a compelling option for larger marine systems where consistent energy production throughout changing conditions is important.

Adequate rear clearance and exposure are essential if you want to benefit from the panel's bifacial capability.

Dual-Glass Construction

Rather than using a conventional polymer backsheet, the Risen uses 1.6mm heat-strengthened glass on both the front and rear of the module.

The front glass features a high-transmission anti-reflective coating, while the rear glass protects the bifacial cells while still allowing reflected light to reach them.

Dual-glass construction also provides strong resistance to moisture and environmental exposure, making it particularly attractive for long-term fixed installations.

Built for Larger Solar Systems

At 475W per module, the Risen allows substantial solar capacity to be built without requiring large numbers of individual panels.

It's well suited to:

• Off-grid battery systems
• Rural properties and farms
• Sheds and workshops
• Ground-mounted solar arrays
• Marine installations
• Residential solar systems
• Commercial and industrial installations
• Larger fixed caravan and motorhome systems where dimensions and weight are suitable

Long-Term Warranty

Risen backs the module with a 25-year product warranty and a 30-year linear power warranty, making it well suited to permanent installations expected to remain in service for decades.
