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 (-0.290 %/°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: Phono Solar PS455L8GF-16/QNH or Phono Solar PS445L8GFH-16/QNH?
According to our database: Phono Solar PS455L8GF-16/QNH has higher module efficiency (22.77% vs 22.27%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Phono Solar PS455L8GF-16/QNH and Phono Solar PS445L8GFH-16/QNH?
Phono Solar PS455L8GF-16/QNH has a module efficiency of 22.77%, while Phono Solar PS445L8GFH-16/QNH is 22.27%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Phono Solar PS455L8GF-16/QNH use vs Phono Solar PS445L8GFH-16/QNH?
Phono Solar PS455L8GF-16/QNH uses TOPCon cells; Phono Solar PS445L8GFH-16/QNH 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 Phono Solar PS455L8GF-16/QNH and Phono Solar PS445L8GFH-16/QNH?
Phono Solar PS455L8GF-16/QNH has a 30 years power warranty; Phono Solar PS445L8GFH-16/QNH 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 Phono Solar PS455L8GF-16/QNH and Phono Solar PS445L8GFH-16/QNH bifacial panels?
Both Phono Solar PS455L8GF-16/QNH and Phono Solar PS445L8GFH-16/QNH 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.
