Frequently Asked Questions about the Trina Vertex S+ 520 Wp
For which applications is the 520 Wp module particularly suitable?
The module is an ideal choice for commercial and industrial rooftop systems (C&I) as well as larger residential installations. Its compact design of less than 2 meters in length allows for easy handling on the roof, and the low voltage design enables more modules per string, leading to shorter wiring. It is also perfectly suited for agriculture, multi-family homes, and PV carports.
How much electricity does the Trina Vertex S+ 520 Wp generate per year?
In Austria, a 520 Wp module generates between 515 and 600 kWh per year, depending on location and orientation. In sunny regions such as Lower Austria, Burgenland, or Styria, yields at the upper end are realistic. At an electricity price of 25 cents/kWh, this corresponds to an annual saving of around 130 to 150 euros per module.
What is the difference between glass-glass and glass-foil?
Glass-glass modules like the Vertex S+ TSM-520NEG18R.28 have hardened glass on both the front AND back. Advantages: significantly more resistant to moisture, UV, microcracks, and mechanical stress, longer lifespan, lower degradation, and better fire protection properties. Ideal for long-term installations over 25+ years.
What does N-Type i-TOPCon technology mean?
N-Type i-TOPCon (innovative Tunnel Oxide Passivated Contact) is the latest generation of silicon cell technology. Advantages over conventional P-Type PERC cells: higher efficiency (23.4% instead of 21%), better low-light performance, lower degradation (only 0.4%/year instead of 0.55%), lower temperature coefficient. More yield in cloudy conditions and less power loss on hot summer days.
Is the module suitable for snowy regions in Austria?
Yes, with a snow load of 5400 Pa on the front side (equivalent to approx. 550 kg/m²) and 2400 Pa wind load on the rear side, the module is ideally suited for alpine locations. The operating temperature range of −40 to +70 °C covers all climatic conditions in Austria.
Which inverters are compatible with the Trina Vertex S+ 520 Wp?
Compatible with all common inverters: Fronius Symo and GEN24, Huawei SUN2000, GoodWe DNS and ET, SMA Sunny Boy and Tripower, SolaX X1/X3-Hybrid and Aelio, Sungrow SH and SG, Solinteg. Thanks to 1500 V DC system voltage and low module voltage (Voc 41.2 V), particularly long strings are possible – ideal for large-scale systems with minimized wiring.
Is the module compatible with optimizers or rapid shutdown?
Yes. The module is available with MC4 EVO2, TS4, and TS4-Plus connectors and is compatible with Tigo TS4 optimizers. This allows for shading-tolerant systems and fire department-compliant rapid shutdown solutions (e.g., for commercial properties) to be implemented without problems. Also compatible with Huawei optimizers.
How many modules do I need for my house?
An average Austrian household consumes 4,500 to 5,500 kWh of electricity per year. With the Trina Vertex S+ 520 Wp, depending on location and roof orientation, you will need between 8 and 12 modules for a typical residential system with 4.2 to 6.2 kWp. For commercial systems from 30 kWp, pallet prices (36 pcs./pallet) are recommended.
Is the module suitable for stables or coastal regions?
Yes. The module is certified against salt mist (IEC 61701), ammonia (IEC 62716), and PID effects. This makes it suitable for agricultural buildings such as stables, coastal areas, and industrial environments where standard modules would degrade prematurely. 3 bypass diodes in the junction box also minimize hot spot losses in partial shading.
Which mounting system is suitable for the Trina 520 Wp?
The module with dimensions 1961 × 1134 × 30 mm and 23.5 kg is compatible with all mounting systems available at SOLARVIC: K2 Systems, Schletter, SL Rack, Novotegra, iFIX Voest System, and Prefa. Both pitched roof and flat roof mounting are possible. For commercial flat roofs, elevated structures or east-west systems are recommended.
