Questions about this pairing

Which panel is better: Jinko Solar JS320P or Jinko Solar JKM735N-66HL5-BDV-Z3-EU?
According to our database: Jinko Solar JKM735N-66HL5-BDV-Z3-EU has higher module efficiency (23.66% vs 16.40%); Jinko Solar JKM735N-66HL5-BDV-Z3-EU 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 JS320P and Jinko Solar JKM735N-66HL5-BDV-Z3-EU?
Jinko Solar JS320P has a module efficiency of 16.40%, while Jinko Solar JKM735N-66HL5-BDV-Z3-EU is 23.66%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JS320P use vs Jinko Solar JKM735N-66HL5-BDV-Z3-EU?
Jinko Solar JS320P uses PERC cells; Jinko Solar JKM735N-66HL5-BDV-Z3-EU 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 JS320P and Jinko Solar JKM735N-66HL5-BDV-Z3-EU?
Jinko Solar JS320P has a 25 years power warranty; Jinko Solar JKM735N-66HL5-BDV-Z3-EU 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 JS320P and Jinko Solar JKM735N-66HL5-BDV-Z3-EU bifacial panels?
Jinko Solar JKM735N-66HL5-BDV-Z3-EU is bifacial (captures light from both faces); Jinko Solar JS320P is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
