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 Transparent 505 or Solitek SOLID Framed White 650W?
According to our database: Solitek SOLID Framed White 650 W has higher module efficiency (22.97% vs 22.31%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Solitek SOLID Framed Transparent 505 and Solitek SOLID Framed White 650W?
Solitek SOLID Framed Transparent 505 has a module efficiency of 22.31%, while Solitek SOLID Framed White 650 W is 22.97%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Solitek SOLID Framed Transparent 505 use vs Solitek SOLID Framed White 650W?
Solitek SOLID Framed Transparent 505 uses TOPCon cells; Solitek SOLID Framed White 650 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 SOLID Framed Transparent 505 and Solitek SOLID Framed White 650W?
Solitek SOLID Framed Transparent 505 has a 30 years power warranty; Solitek SOLID Framed White 650 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 SOLID Framed Transparent 505 and Solitek SOLID Framed White 650W bifacial panels?
Both Solitek SOLID Framed Transparent 505 and Solitek SOLID Framed White 650 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.
