BYD HSBK-33-725 vs BYD HSBK-33-730

Q: Which panel is better: BYD HSBK-33-725 or BYD HSBK-33-730?

According to our database: BYD HSBK-33-730 has higher module efficiency (23.50% vs 23.34%). 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 HSBK-33-730?

BYD HSBK-33-725 has a module efficiency of 23.34%, while BYD HSBK-33-730 is 23.50%. 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 HSBK-33-730?

BYD HSBK-33-725 uses HJT cells; BYD HSBK-33-730 uses HJT. 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 HSBK-33-730?

BYD HSBK-33-725 has a 30 years power warranty; BYD HSBK-33-730 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 HSBK-33-730 bifacial panels?

Both BYD HSBK-33-725 and BYD HSBK-33-730 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.

The verdict

Identical on every published parameter

All 19 comparable parameters agree. Two records this alike are usually one panel sold under two names, or two bins of the same production line - decide on price and on who you would rather buy from.

Each panel's own declared degradation curve, at 1,200 kWh/kWp a year

Cell temperature

Same temp coeff. for both panels (-0.240 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.
