Key takeaway
Trina Solar launches monofacial Vertex-N series module for lightweight roof and anti-dust C&I roof applications
Both models offer a power output of up to 630 W and an efficiency of up to 23.3%
The low weight of 27.9 kg and optimized dimensions enhance the module’s installation flexibility on multiple types of low-load roofs
The 630 W anti-dust module is best suited for low-angle C&I roof applications
Trina Solar, one of the leading Chinese n-TOPCon module makers, recently introduced the 2 latest additions to its Vertex-N module series in the glass-to-backsheet category – a lightweight and anti-dust module. With identical features, the 2 modules are targeted at global C&I rooftop applications. The characteristics of both models can be categorized into multiple key metrics.
Performance
Both modules, equipped with 132 half-cut pieces of 210R size n-type i-TOPCon advanced technology cells, boast a power output of 630 W and an efficiency of 23.3%. The company emphasized that its 2,382 x 1,134 mm dimension 210R size cell-based module yields an additional power output of up to 30 W compared to the 2,278 x 1,134 mm dimension 182-72N series module. The latest 630 W nameplate-rated module boasts an additional string power of up to 18% compared to the same number of 182-72N series modules in a string, added Trina Solar. It adds that these additional power gains contribute to optimized balance-of-system (BOS) cost and lower levelized cost of energy generation (LCOE) of solar power plants.
Installation & Commissioning
The glass-backsheet module, with dimensions of 2,382 x 1,134 mm and weighing 27.9 kg, is suitable for C&I low-load roof applications. These modules, featuring a weight of 10.7 kg/m², well below the maximum load-carrying capacity of colored steel tile roofs, are best suited for C&I low-load roof installations, explained Trina Solar. The module’s size and low weight enhances installation flexibility on multiple types of low-load roofs - sloped roofs, concrete flat roofs, and color steel tile roofs.
Transportation
Along with additional power gain and flexibility in installation, the optimum size of this latest module format offers optimization in transportation costs to the customer site by enhancing conventional container space utilization to up to 98.5%.
Anti-dust application solution
The 630 W anti-dust model, equipped with a patented and optimized frame design, prevents sealant overflow and resists potential moisture ingression while ensuring lamination adhesion strength and high-load performance in low inclination angle installation. Its low-angle installation and anti-dust feature mitigate the potential risk of dust accumulation, which improves the module’s reliability and power generation, added Trina Solar. Along with improved module life span and power gain, its anti-dust property also saves additional system design costs for low-angle C&I roof installations.
Quality and reliability
Both glass-backsheet modules, fabricated with n-type i-TOPCon cells, are internally tested with enhanced stress conditions to validate the product’s durability and reliability in extreme weather and stresses. These enhanced reliability tests included 45 mm hail tests for hailstorm events followed by 20 times higher dynamic mechanical load testing for high wind load conditions. Also, the enhanced PID, damp heat (DH), thermal cycle (TC), ultra-violet (UV)+TC50+ humidity freeze (HF10) test sequence, LeTID tests, and an extremely low-temperature outdoor performance test substantiate the resilience of the module’s chosen bill-of-materials (BOM) against multiple potential fault modes.
Trina Solar confirmed that both modules have entered mass production, are commercially available, and being delivered worldwide.
