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 Magnus 510 or Solitek Forza 650?
According to our database: Solitek Forza 650 has higher module efficiency (22.97% vs 22.93%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Solitek Magnus 510 and Solitek Forza 650?
Solitek Magnus 510 has a module efficiency of 22.93%, while Solitek Forza 650 is 22.97%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Solitek Magnus 510 use vs Solitek Forza 650?
Solitek Magnus 510 uses TOPCon cells; Solitek Forza 650 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 Magnus 510 and Solitek Forza 650?
Solitek Magnus 510 has a 30 years power warranty; Solitek Forza 650 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 Magnus 510 and Solitek Forza 650 bifacial panels?
Both Solitek Magnus 510 and Solitek Forza 650 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.
