• Residential rooftop solar installations
• Commercial rooftops and distributed solar projects
• Schools, offices, retail buildings, and municipal facilities
• Ground-mounted systems with compatible racking
• Off-grid and battery-based systems with compatible equipment
• Projects requiring documented domestic content
• Installations seeking high output from available mounting space

N-Type Half-Cell Technology

The module combines N-type monocrystalline cells with a half-cell layout and multi-busbar connections. These features help reduce electrical resistance and mismatch losses within the panel.

The manufacturer highlights low-light performance and reduced losses from partial shading. Output still depends on sunlight, shading patterns, orientation, temperature, and the complete system design.

A -0.29%/°C power temperature coefficient describes how output changes as cell temperature rises above standard test conditions.

Built for Outdoor Installations

The Sirius 450W module uses 3.2mm anti-reflective coated tempered glass, an anodized aluminum alloy frame, and an IP68-rated junction box.

The datasheet lists mechanical loads of 5,400Pa on both the front and rear. Applicable load capacity depends on the approved mounting arrangement and manufacturer installation requirements.

The operating temperature range is -40°F to 185°F. The datasheet also lists IEC 62804 testing for resistance to potential-induced degradation.

Warranty Coverage

The manufacturer advertises up to a 25-year product warranty and a 30-year linear power output warranty for this series.

Confirm the warranty applicable to the supplied configuration and installation location. Coverage is subject to the manufacturer’s warranty terms and requirements.

Product Specifications

Mounting and Equipment Compatibility

Select racking that accommodates the panel dimensions, 35mm frame, approved clamp locations, and site-specific structural loads.

String inverters, microinverters, optimizers, and charge controllers must support the module’s electrical characteristics. Confirm cold-weather voltage, MPPT operating range, current limits, and the permitted number of connected modules.

This listing is for the solar panel. Racking, inverters, batteries, extension cables, and other installation materials are sold separately. Manufacturer pallet quantity describes packing configuration and does not change the quantity selected when ordering.
