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.

Questions about this pairing

Which panel is better: Solitek SOLID Framed White 650W or Solitek SOLID Black Frameless 455?
According to our database: Solitek SOLID Framed White 650 W has higher module efficiency (22.97% vs 22.57%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Solitek SOLID Framed White 650W and Solitek SOLID Black Frameless 455?
Solitek SOLID Framed White 650 W has a module efficiency of 22.97%, while Solitek SOLID Black Frameless 455 is 22.57%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Solitek SOLID Framed White 650W use vs Solitek SOLID Black Frameless 455?
Solitek SOLID Framed White 650 W uses TOPCon cells; Solitek SOLID Black Frameless 455 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 Solitek SOLID Framed White 650W and Solitek SOLID Black Frameless 455?
Solitek SOLID Framed White 650 W has a 30 years power warranty; Solitek SOLID Black Frameless 455 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 Solitek SOLID Framed White 650W and Solitek SOLID Black Frameless 455 bifacial panels?
Both Solitek SOLID Framed White 650 W and Solitek SOLID Black Frameless 455 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.
