BYD NLBK-36 585 vs BYD NLBK-36 595

Q: Which panel is better: BYD NLBK-36 585 or BYD NLBK-36 595?

According to our database: BYD NLBK-36 595 has higher module efficiency (23.03% vs 22.65%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of BYD NLBK-36 585 and BYD NLBK-36 595?

BYD NLBK-36 585 has a module efficiency of 22.65%, while BYD NLBK-36 595 is 23.03%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does BYD NLBK-36 585 use vs BYD NLBK-36 595?

BYD NLBK-36 585 uses TOPCon cells; BYD NLBK-36 595 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 NLBK-36 585 and BYD NLBK-36 595?

BYD NLBK-36 585 has a 30 years power warranty; BYD NLBK-36 595 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 NLBK-36 585 and BYD NLBK-36 595 bifacial panels?

Both BYD NLBK-36 585 and BYD NLBK-36 595 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.

What it means on a roof

Thirty years of production

Declared annual degradation, with a 1.0% first-year loss assumed for both panels because at least one datasheet omits it, at 1,200 kWh/kWp a year

Cell temperature

Same temp coeff. for both panels (-0.278 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.
