BYD HSBK-33-725 vs BYD NSBK-33-720

Q: Which panel is better: BYD HSBK-33-725 or BYD NSBK-33-720?

According to our database: BYD HSBK-33-725 has higher module efficiency (23.34% vs 23.19%); BYD HSBK-33-725 tolerates heat better (temp coeff -0.240%/°C vs -0.278%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of BYD HSBK-33-725 and BYD NSBK-33-720?

BYD HSBK-33-725 has a module efficiency of 23.34%, while BYD NSBK-33-720 is 23.19%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does BYD HSBK-33-725 use vs BYD NSBK-33-720?

BYD HSBK-33-725 uses HJT cells; BYD NSBK-33-720 uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on BYD HSBK-33-725 and BYD NSBK-33-720?

BYD HSBK-33-725 has a 30 years power warranty; BYD NSBK-33-720 has a 30 years power warranty. The power warranty guarantees a minimum percentage of rated output at the end of the warranty period (typically 80-87%). Product (materials) warranties are usually shorter.

Q: Are BYD HSBK-33-725 and BYD NSBK-33-720 bifacial panels?

Both BYD HSBK-33-725 and BYD NSBK-33-720 are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
