Series Helios Module Series (N-HJT HIGH EFFICIENCY MONO 132-20BB-W-WG) 5 variants
The Phono Solar Helios Module (N-HJT HIGH EFFICIENCY MONO 132-20BB-W-WG) was designed to maximize energy gain under real-world operating conditions – even when the roof has limited space, and the investor expects stable production for years. Its unique combination of N-type HJT cells and glass-glass dual-string construction ensures superior mechanical strength and better laminate sealing compared to many standard modules. The application of 20BB multi-string architecture minimizes connection losses and improves performance under partial shading, which is crucial in single-family home installations and commercial rooftops with obstacles. HJT technology also provides excellent performance at high temperatures and a better response to low light conditions, enabling the system to generate more energy in the morning, evening, and on cloudy days. This is the ideal choice for prosumers, agriculture, and businesses seeking reliability, longevity, and real-world growth in self-consumption.
