Questions about this pairing

Which panel is better: Jinko Solar JS315P or Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735W bin)?
According to our database: Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735 W bin) has higher module efficiency (23.66% vs 16.20%); Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735 W bin) tolerates heat better (temp coeff -0.290%/°C vs -0.420%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Jinko Solar JS315P and Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735W bin)?
Jinko Solar JS315P has a module efficiency of 16.20%, while Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735 W bin) is 23.66%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JS315P use vs Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735W bin)?
Jinko Solar JS315P uses PERC cells; Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735 W bin) 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 Jinko Solar JS315P and Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735W bin)?
Jinko Solar JS315P has a 25 years power warranty; Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735 W bin) 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 Jinko Solar JS315P and Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735W bin) bifacial panels?
Jinko Solar JKM710-735N-66HL5-BDV-Z3-EU (735 W bin) is bifacial (captures light from both faces); Jinko Solar JS315P is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
