Questions about this pairing

Which panel is better: JA Solar JAM72D30-565/LB/1500V or JA Solar JAM72D30-570/LB/1500V?
According to our database: JA Solar JAM72D30-570/LB/1500V has higher module efficiency (21.50% vs 21.40%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of JA Solar JAM72D30-565/LB/1500V and JA Solar JAM72D30-570/LB/1500V?
JA Solar JAM72D30-565/LB/1500V has a module efficiency of 21.40%, while JA Solar JAM72D30-570/LB/1500V is 21.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does JA Solar JAM72D30-565/LB/1500V use vs JA Solar JAM72D30-570/LB/1500V?
JA Solar JAM72D30-565/LB/1500V uses PERC cells; JA Solar JAM72D30-570/LB/1500V uses PERC. 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 JA Solar JAM72D30-565/LB/1500V and JA Solar JAM72D30-570/LB/1500V?
JA Solar JAM72D30-565/LB/1500V has a 30 years power warranty; JA Solar JAM72D30-570/LB/1500V 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 JA Solar JAM72D30-565/LB/1500V and JA Solar JAM72D30-570/LB/1500V bifacial panels?
Both JA Solar JAM72D30-565/LB/1500V and JA Solar JAM72D30-570/LB/1500V 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.
