What it means on a roof
Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
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.

Questions about this pairing
Which panel is better: Solarever SE-182*105-620M-132-BD or Solarever SE-182*105-605M-132-BD?
According to our database: Solarever SE-182*105-620M-132-BD has higher module efficiency (22.95% vs 22.40%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Solarever SE-182*105-620M-132-BD and Solarever SE-182*105-605M-132-BD?
Solarever SE-182*105-620M-132-BD has a module efficiency of 22.95%, while Solarever SE-182*105-605M-132-BD is 22.40%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Solarever SE-182*105-620M-132-BD use vs Solarever SE-182*105-605M-132-BD?
Solarever SE-182*105-620M-132-BD uses TOPCon cells; Solarever SE-182*105-605M-132-BD 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 Solarever SE-182*105-620M-132-BD and Solarever SE-182*105-605M-132-BD?
Solarever SE-182*105-620M-132-BD has a 30 years power warranty; Solarever SE-182*105-605M-132-BD 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 Solarever SE-182*105-620M-132-BD and Solarever SE-182*105-605M-132-BD bifacial panels?
Both Solarever SE-182*105-620M-132-BD and Solarever SE-182*105-605M-132-BD 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.
