Questions about this pairing

Which panel is better: Phono Solar PS475L7GFH-18/VBH or Phono Solar NS-720MH-132?
According to our database: Phono Solar PS475L7GFH-18/VBH has higher module efficiency (23.27% vs 23.17%); 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 PS475L7GFH-18/VBH and Phono Solar NS-720MH-132?
Phono Solar PS475L7GFH-18/VBH has a module efficiency of 23.27%, while Phono Solar NS-720MH-132 is 23.17%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Phono Solar PS475L7GFH-18/VBH use vs Phono Solar NS-720MH-132?
Phono Solar PS475L7GFH-18/VBH uses Back Contact cells; Phono Solar NS-720MH-132 uses N-type. 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 PS475L7GFH-18/VBH and Phono Solar NS-720MH-132?
Phono Solar PS475L7GFH-18/VBH has a 30 years power warranty; Phono Solar NS-720MH-132 has a 25 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 PS475L7GFH-18/VBH and Phono Solar NS-720MH-132 bifacial panels?
Phono Solar PS475L7GFH-18/VBH is bifacial (captures light from both faces); Phono Solar NS-720MH-132 is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
