Advantages at a glance
TNC 2.0 N-type Cell Technology
96 half-cells in a 6 × 16 layout on n-type wafers. Higher efficiency, practically no LID/LeTID, and a favorable temperature coefficient of −0.28 %/°C.
Complete Full-Black Design
Black anodized aluminum frame, black cell connectors, and deep dark glass create a homogeneous, calm appearance – the visually best choice for sophisticated homes.
Glass-Glass with 2.0/2.0 mm
2.0 mm semi-tempered glass on both sides instead of a backsheet. Significantly higher mechanical stability, no film outgassing, and more stable yields in the long term.
6000 Pa Snow Load
6000 Pa on the front (≈610 kg/m²) and 4000 Pa on the back – exceptionally high and thus ideally suited for alpine locations in Austria.
Compact and Easy to Handle
Measuring 1762 × 1134 mm and weighing 23.7 kg, the module can be easily installed even on smaller and intricately shaped roof areas – comfortable to handle by two people.
15 Years Product, 30 Years Performance
15 years material and workmanship warranty, and 30 years linear performance warranty with at least 87.4 % remaining performance. Only −1.0 % in the first year, then −0.4 % per year.

Frequently Asked Questions
What does TNC 2.0 mean and why is this technology better?
TNC stands for Tongwei N-type Cell – Tongwei's in-house TOPCon cell platform. An ultra-thin tunnel oxide layer is applied to an n-type silicon wafer, which significantly reduces recombination losses. Compared to classic PERC, this means: higher efficiency, practically no light-induced power loss, better low-light performance, and a more favorable temperature coefficient of −0.28 %/°C.
What is the difference between glass-glass and glass-film?
In this module, both the front and back are made of 2.0 mm semi-tempered glass. Glass does not age like a plastic backsheet, does not outgas, and does not absorb moisture. The result: higher mechanical stiffness, better anti-PID properties, and slower degradation over the entire lifespan.
How much electricity does the module generate per year in Austria?
A 455 Wp module in Austria generates between 450 and 520 kWh per year, depending on the location, orientation, and tilt. At an electricity price of 25 cents/kWh, this corresponds to approximately 112 to 130 Euros in savings per module per year.
How many modules do I need for my home?
An average Austrian household consumes 4,500 to 5,500 kWh per year. With this 455 Wp module, you will need between 10 and 13 pieces for a typical home system of 4.5 to 5.9 kWp, depending on the location and roof orientation. SOLARVIC will be happy to advise you on the design.
Is the module suitable for alpine locations?
Yes, especially well. With a static load capacity of 6000 Pa on the front (≈610 kg/m²) and 4000 Pa on the back, it is significantly above the market standard of 5400 Pa. The operating temperature of −40 to +85 °C covers all climatic conditions in Austria, and the module has passed the hail resistance test.
Who is Tongwei?
Tongwei Solar is a subsidiary of the publicly listed Chinese Tongwei Group based in Chengdu. The company has been the world's largest manufacturer of solar cells for years and produces according to ISO 9001, ISO 14001, ISO 45001, and ISO 50001. The modules are certified according to IEC 62941 for manufacturing quality.
