1x Astronergy ASTRO N7s CHSM48RN(DG)/F-BH 450W Black Frame bifacial solar module
The Astronergy ASTRO N7s CHSM48RN(DG)/F-BH 450W solar module combines state-of-the-art solar technology with an elegant design. Thanks to its compact size of less than 2 m² and moderate weight of only 24,4 kg, it can be easily transported and installed by a single person – and its black frame blends perfectly into any roofscape.
Bifacial TOPCon 4.0 technology for maximum yield
The module utilizes TOPCon 4.0 cell technology with rectangular wafers and innovative ZBB (Zero Bus Bar) technology, which optimizes power harvesting and reduces losses. The bifacial design not only allows for the use of direct sunlight on the front but also delivers additional yields on the back through reflected light – particularly effective on light-colored surfaces or in elevated mounting positions.
Technical highlights
- Nominal power: 450W with a module efficiency of 22,5%
- Black frame with glass-glass construction (2+2 mm) for durability and aesthetics
- TOPCon 4.0 cell technology with 0,3–0,5% higher efficiency compared to TOPCon 3.0 PELIA
- Excellent temperature coefficient of only -0,29%/°C – less power loss in hot conditions
- 25-year product warranty and 30-year linear performance warranty
- Low LID & LETID degradation and excellent low-light performance Astronergy
