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 Forza 720 or Solitek SOLID Semi-Clear Framed 455 W?
According to our database: Solitek Forza 720 has higher module efficiency (23.18% vs 22.77%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Solitek Forza 720 and Solitek SOLID Semi-Clear Framed 455 W?
Solitek Forza 720 has a module efficiency of 23.18%, while Solitek SOLID Semi-Clear Framed 455 W is 22.77%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Solitek Forza 720 use vs Solitek SOLID Semi-Clear Framed 455 W?
Solitek Forza 720 uses TOPCon cells; Solitek SOLID Semi-Clear Framed 455 W 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 Forza 720 and Solitek SOLID Semi-Clear Framed 455 W?
Solitek Forza 720 has a 30 years power warranty; Solitek SOLID Semi-Clear Framed 455 W 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 Forza 720 and Solitek SOLID Semi-Clear Framed 455 W bifacial panels?
Both Solitek Forza 720 and Solitek SOLID Semi-Clear Framed 455 W 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.
