Questions about this pairing

Which panel is better: Solarwatt SOLARWATT Panel vision M 5.0 450 Wp or Solaria Solaria PowerX-395R?
According to our database: Solarwatt SOLARWATT Panel vision M 5.0 450 Wp has higher module efficiency (22.50% vs 20.20%); Solarwatt SOLARWATT Panel vision M 5.0 450 Wp tolerates heat better (temp coeff -0.290%/°C vs -0.360%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Solarwatt SOLARWATT Panel vision M 5.0 450 Wp and Solaria Solaria PowerX-395R?
Solarwatt SOLARWATT Panel vision M 5.0 450 Wp has a module efficiency of 22.50%, while Solaria Solaria PowerX-395R is 20.20%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Solarwatt SOLARWATT Panel vision M 5.0 450 Wp use vs Solaria Solaria PowerX-395R?
Solarwatt SOLARWATT Panel vision M 5.0 450 Wp uses TOPCon cells; Solaria Solaria PowerX-395R uses Monocrystalline. 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 Solarwatt SOLARWATT Panel vision M 5.0 450 Wp and Solaria Solaria PowerX-395R?
Solarwatt SOLARWATT Panel vision M 5.0 450 Wp has a 30 years power warranty; Solaria Solaria PowerX-395R 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 Solarwatt SOLARWATT Panel vision M 5.0 450 Wp and Solaria Solaria PowerX-395R bifacial panels?
Solarwatt SOLARWATT Panel vision M 5.0 450 Wp is bifacial (captures light from both faces); Solaria Solaria PowerX-395R is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
