Solar Module Trina Solar TSM-NEG18R.28 515W

The module uses monocrystalline silicon N-type cells in a half-cut design with 16 busbars. N-type cells show lower light-induced degradation, more favorable temperature behavior, and higher yield over their lifetime than classic P-type cells. This allows the module to achieve 23.2% efficiency at 515 Wp.

Instead of a plastic backsheet, the cells are located between two 1.6 mm thick glass panes. This double-glass composite permanently protects the cells from moisture and UV radiation, is mechanically more stable, and reduces micro-cracks – the basis for the 30-year performance warranty.

A 515 Wp module in Austria generates around 490 to 570 kWh per year, depending on orientation and location. At an electricity price of approximately 25 ct/kWh, this corresponds to savings of roughly 120 to 145 Euros annually per module.

For a typical annual consumption of 4500 to 5500 kWh, about 9 to 12 of these 515 Wp modules are suitable, resulting in approximately 4.6 to 6.2 kWp. The exact number depends on the roof area, orientation, and any battery storage.

Yes. The module is tested for snow loads up to 5400 Pa and wind loads up to 2400 Pa, making it suitable for snowy regions in the Alps. The glass-glass composite and the IP68 protection rating of the junction box also ensure robustness against weather and temperature fluctuations.

Trina Solar is one of the world's largest manufacturers of photovoltaic modules and has been established in the market for many years. The company produces crystalline solar modules for residential, commercial, and large-scale installations and offers a 25-year product warranty and 30-year performance warranty on this module.
