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 (-0.300 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

According to our database: Solarever SE-182*105-470M-96-BD has higher module efficiency (23.52% vs 22.52%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Solarever SE-182*105-450M-96-BD and Solarever SE-182*105-470M-96-BD?
Solarever SE-182*105-450M-96-BD has a module efficiency of 22.52%, while Solarever SE-182*105-470M-96-BD is 23.52%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Solarever SE-182*105-450M-96-BD use vs Solarever SE-182*105-470M-96-BD?
Solarever SE-182*105-450M-96-BD uses TOPCon cells; Solarever SE-182*105-470M-96-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*105-450M-96-BD and Solarever SE-182*105-470M-96-BD?
Solarever SE-182*105-450M-96-BD has a 30 years power warranty; Solarever SE-182*105-470M-96-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*105-450M-96-BD and Solarever SE-182*105-470M-96-BD bifacial panels?
Both Solarever SE-182*105-450M-96-BD and Solarever SE-182*105-470M-96-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.
