Questions about this pairing

Which panel is better: Phono Solar NS-730MH-132 or Phono Solar PS475L7GFH-18/VBH?
According to our database: Phono Solar NS-730MH-132 has higher module efficiency (23.50% vs 23.27%); Phono Solar PS475L7GFH-18/VBH tolerates heat better (temp coeff -0.260%/°C vs -0.290%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Phono Solar NS-730MH-132 and Phono Solar PS475L7GFH-18/VBH?
Phono Solar NS-730MH-132 has a module efficiency of 23.50%, while Phono Solar PS475L7GFH-18/VBH is 23.27%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Phono Solar NS-730MH-132 use vs Phono Solar PS475L7GFH-18/VBH?
Phono Solar NS-730MH-132 uses N-type cells; Phono Solar PS475L7GFH-18/VBH uses Back Contact. 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 NS-730MH-132 and Phono Solar PS475L7GFH-18/VBH?
Phono Solar NS-730MH-132 has a 25 years power warranty; Phono Solar PS475L7GFH-18/VBH 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 NS-730MH-132 and Phono Solar PS475L7GFH-18/VBH bifacial panels?
Phono Solar PS475L7GFH-18/VBH is bifacial (captures light from both faces); Phono Solar NS-730MH-132 is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
