Half-Cell Monocrystalline Technology

The module uses 108 half-cut monocrystalline cells with 10 busbars and 3 bypass diodes. Half-cell architecture reduces internal resistance losses and improves performance under partial shading, while the 10BB design shortens current paths for more efficient power collection.

Electrical Performance

The panel operates at 31.00V / 12.92A at maximum power, with an open-circuit voltage of 37.15V and short-circuit current of 13.55A. It is compatible with systems up to 1,500V and has a maximum series fuse rating of 25A. Temperature coefficients are −0.35%/°C (Pmax), −0.22%/°C (Voc), and 0.05%/°C (Isc).

Durable Construction

A 3.2 mm high-transmission, tempered, anti-reflective glass front is paired with a black backsheet and a black anodized aluminum frame. The panel is rated for wind and snow loads up to 112 lbs/ft² (5400 Pa) and carries a Class C / Type 1 fire performance rating.

All-Black Aesthetics

With a black backsheet and black frame, the Solstice panel delivers a clean, uniform look that blends well with dark roofing, which makes it a strong choice for visible residential rooftops.

Wiring and Connections

Each module includes an IP68-rated junction box, 12 AWG (4 mm²) PV wire output cables measuring 47.2 in (1.2 m), and genuine Stäubli MC4 connectors for reliable, weather-resistant connections.

Operating Conditions

The panel is designed to operate from −40°F to 185°F (−40°C to 85°C), with a nominal operating cell temperature of 113°F ± 3.6°F (45 ± 2°C).

Certifications and Warranty

UL listed to UL 61730-1 and UL 61730-2. CertainTeed's 25-year linear power output warranty guarantees 98% output in year one, declining linearly to 85% at year 25. See CertainTeed's limited warranty for full details.
