Thornova 450Wp N-Type Bifacial Solar Panel TS-BGT48(450)-G11 – Wholesale 31 panels per pallet

TS-BGT48(450)-G11 Alpine Heavy Snow is part of the Tangra S Pro HD Alpine Black Series — Thornova Solar's reinforced module built specifically for heavy snow load regions. It uses the same N-type monocrystalline cell technology as the standard Tangra S Pro HD line, but with a thicker frame and glass package rated for extreme mechanical stress.

Enhanced light trapping and optimized current collection contribute to the improvement of both module power output and reliability. N-type cells also have no LID (Light Induced Degradation) by nature, further protecting long-term output even after decades in harsh alpine climates.

Given its compact size and weight, the TS-BGT48(450)-G11 Alpine efficiency of 22.5% is quite impressive. Bifacial technology allows for the harvesting of up to an additional 30% energy from the rear side of the module, depending on installation conditions. What sets this variant apart is its durability: Thornova Solar backs it with a 30-year product warranty (double the standard line's 15 years) and a 30-year linear power warranty guaranteeing at least 87.4% output retention.

• 30 years of product warranty and 30 years of linear power warranty
• Wholesale packaging: 31 panels per pallet / 806 panels per 40'HQ container

Higher efficiency of up to 22.5%

TS-BGT48(450)-G11 Alpine guarantees outstanding power output. N-type cell technology combined with a full black design and anti-reflection coating result in 22.5% module efficiency, identical to the standard line — the difference here is structural, not electrical.

Built for extreme snow and wind load

This is the key differentiator of the Alpine variant: it's certified to withstand up to 8100 Pa of front-side static loading and 5400 Pa on the rear — roughly 50% higher than the standard Tangra S Pro HD — plus 35mm hailstone impact resistance. This makes it the right choice for rooftops and ground-mount arrays in regions with heavy seasonal snowfall.

High quality standards

Every module undergoes a 100% triple EL test, dramatically reducing hidden crack rates. Certifications include ISO9001:2015, ISO14001:2015, ISO45001:2018, and ETL/Intertek listing, with optional performance warranty insurance available through Munich Re and Ariel Re.

Low degradation for increased longevity

In the first year of service, these panels will lose no more than 1% of their power output. The average yearly power drop from the second to the 30th year will be no more than 0.4%. After 30 years, the modules will retain more than 87.4% of their initial output.
