Description
Sunpro Power 440W N-Type TOPCon Bifacial Solar Panel – Full Pallet of 36
Model: SPDG440-N108M10
The Sunpro Power SPDG440-N108M10 is a 440W N-type monocrystalline TOPCon bifacial solar panel built for high output, strong low-light performance and dependable long-term energy production. Its 108 half-cell format, full-black front appearance and compact 67.8 x 44.65-inch footprint make it well suited to residential, light commercial and distributed-generation projects.
Dual-glass construction allows the rear of the module to capture reflected sunlight when installed over a suitable surface. With 15% rear-side gain, total module output can reach up to 506W under test conditions. Bifacial gain varies with mounting height, tilt, spacing, ground reflectivity and site conditions.
Key Benefits
Best Uses
- Residential rooftops: High-efficiency output and a full-black appearance for space-conscious home solar arrays.
- Ground-mount systems: Bifacial construction can increase energy production where reflected light reaches the back of the panel.
- Light commercial projects: Full-pallet packaging supports efficient purchasing for larger installations.
- Carports, pergolas and elevated arrays: Suitable where the installation is engineered for the module dimensions, loads and approved clamp zones.

Warranty and Long-Term Output
The SPDG440-N108M10 is backed by a 15-year product quality warranty and a 30-year linear power warranty. The linear power warranty provides for at least 99% of rated output after the first year, 89.4% at year 25 and 87.4% at year 30. Manufacturer warranty terms apply.
Installation Notes
- Confirm inverter, optimizer or microinverter voltage and current compatibility before ordering.
- Use mounting hardware approved for the module’s 30 mm frame, dimensions, weight and specified clamp zones.
- Rear-side production depends on system design. Maintain appropriate clearance and avoid blocking the rear glass when seeking bifacial gain.
- Mechanical load ratings depend on the approved mounting method and installation requirements. Site-specific engineering and local code requirements still apply.
- Installation and electrical connections should be completed in accordance with Sunpro documentation, applicable codes and local authority requirements.
Frequently Asked Questions
How many panels are included?
This listing includes one full pallet containing 36 Sunpro Power 440W panels. The pallet provides 15.84 kW of combined front-side rated DC capacity.
Is this a full-black solar panel?
Yes. This model is part of Sunpro’s full-black module series and is designed to provide a clean front-side appearance. It remains a bifacial, dual-glass module, so the rear surface is designed to receive reflected light.
Can this panel produce more than 440W?
440W is the module’s front-side rating at standard test conditions. With 15% rear-side gain, total module output can reach up to 506W under test conditions. Output varies based on sunlight, temperature, tilt, mounting clearance, ground reflectivity and other site conditions.
What connectors and cable length are included?
Each panel includes factory-installed Stäubli MC4 connectors and 1,100 mm output leads using 4 mm² cable.
Is mounting hardware included?
No. Racking, clamps, electrical equipment and other balance-of-system components are sold separately. Select mounting hardware based on the installation type, local loads, the 30 mm module frame and Sunpro’s approved mounting zones.
Can these panels be used with a microinverter?
They may be used with compatible equipment, but the match must be verified using the panel’s Voc, Vmp, Isc and Imp ratings, including required temperature and code calculations. Do not select an inverter or microinverter based on wattage alone.
What is the product warranty?
Sunpro backs this module with a 15-year product quality warranty and a 30-year linear power warranty, providing long-term protection for the panel and its energy output. Manufacturer warranty terms apply.
