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 Semi-Clear Framed 455 W or Solitek Forza 720?
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 SOLID Semi-Clear Framed 455 W and Solitek Forza 720?
Solitek SOLID Semi-Clear Framed 455 W has a module efficiency of 22.77%, while Solitek Forza 720 is 23.18%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Solitek SOLID Semi-Clear Framed 455 W use vs Solitek Forza 720?
Solitek SOLID Semi-Clear Framed 455 W uses TOPCon cells; Solitek Forza 720 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 Semi-Clear Framed 455 W and Solitek Forza 720?
Solitek SOLID Semi-Clear Framed 455 W has a 30 years power warranty; Solitek Forza 720 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 Semi-Clear Framed 455 W and Solitek Forza 720 bifacial panels?
Both Solitek SOLID Semi-Clear Framed 455 W and Solitek Forza 720 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.
