Jinko Solar JKM590N-72HL4-(V) vs Jinko Solar JKM615-635N-78HL4-(V)-F6-EN (615W variant)

Q: Which panel is better: Jinko Solar JKM590N-72HL4-(V) or Jinko Solar JKM615-635N-78HL4-(V)-F6-EN (615W variant)?

According to our database: Jinko Solar JKM590N-72HL4-(V) has higher module efficiency (22.84% vs 22.00%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Jinko Solar JKM590N-72HL4-(V) and Jinko Solar JKM615-635N-78HL4-(V)-F6-EN (615W variant)?

Jinko Solar JKM590N-72HL4-(V) has a module efficiency of 22.84%, while Jinko Solar JKM615-635N-78HL4-(V)-F6-EN (615W variant) is 22.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Jinko Solar JKM590N-72HL4-(V) use vs Jinko Solar JKM615-635N-78HL4-(V)-F6-EN (615W variant)?

Jinko Solar JKM590N-72HL4-(V) uses TOPCon cells; Jinko Solar JKM615-635N-78HL4-(V)-F6-EN (615W variant) uses N-type. 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 Jinko Solar JKM590N-72HL4-(V) and Jinko Solar JKM615-635N-78HL4-(V)-F6-EN (615W variant)?

Jinko Solar JKM590N-72HL4-(V) has a 30 years power warranty; Jinko Solar JKM615-635N-78HL4-(V)-F6-EN (615W variant) 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.

What it means on a roof

Thirty years of production

Each panel's own declared degradation curve, at 1,200 kWh/kWp a year

Cell temperature

Same temp coeff. for both panels (-0.290 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.
