Longi Solar LR7-72HVH-670M vs Jinko Solar JKM650-670N-66QL6-BDV (670W class)

Q: What is the efficiency of Longi Solar LR7-72HVH-670M and Jinko Solar JKM650-670N-66QL6-BDV (670W class)?

Longi Solar LR7-72HVH-670M has a module efficiency of 24.80%, while Jinko Solar JKM650-670N-66QL6-BDV (670W class) is 24.80%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Longi Solar LR7-72HVH-670M use vs Jinko Solar JKM650-670N-66QL6-BDV (670W class)?

Longi Solar LR7-72HVH-670M uses N-type cells; Jinko Solar JKM650-670N-66QL6-BDV (670W class) uses TOPCon. 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 Longi Solar LR7-72HVH-670M and Jinko Solar JKM650-670N-66QL6-BDV (670W class)?

Longi Solar LR7-72HVH-670M has a 30 years power warranty; Jinko Solar JKM650-670N-66QL6-BDV (670W class) 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.

Q: Are Longi Solar LR7-72HVH-670M and Jinko Solar JKM650-670N-66QL6-BDV (670W class) bifacial panels?

Jinko Solar JKM650-670N-66QL6-BDV (670W class) is bifacial (captures light from both faces); Longi Solar LR7-72HVH-670M is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.

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 (-0.260 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.
