Questions about this pairing

Which panel is better: BYD NLBK-36 600 or BYD NLBK-36-590?
According to our database: BYD NLBK-36 600 has higher module efficiency (23.23% vs 22.84%); BYD NLBK-36 600 tolerates heat better (temp coeff -0.278%/°C vs -0.300%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of BYD NLBK-36 600 and BYD NLBK-36-590?
BYD NLBK-36 600 has a module efficiency of 23.23%, while BYD NLBK-36-590 is 22.84%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does BYD NLBK-36 600 use vs BYD NLBK-36-590?
BYD NLBK-36 600 uses TOPCon cells; BYD NLBK-36-590 uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.
What is the warranty on BYD NLBK-36 600 and BYD NLBK-36-590?
BYD NLBK-36 600 has a 30 years power warranty; BYD NLBK-36-590 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.
Are BYD NLBK-36 600 and BYD NLBK-36-590 bifacial panels?
Both BYD NLBK-36 600 and BYD NLBK-36-590 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.

Every figure here is from the manufacturers' own datasheets - a dash means the value is not published, never an estimate. The thirty-year projection and the temperature scenarios are calculations from those figures, and each states its assumption above.
