Questions about this pairing

Which panel is better: Solarwatt SOLARWATT Panel vision GM 3.0 style 360 or Solarwatt SOLARWATT Panel vision M 5.0 460 Wp?
According to our database: Solarwatt SOLARWATT Panel vision M 5.0 460 Wp has higher module efficiency (23.00% vs 19.40%); Solarwatt SOLARWATT Panel vision M 5.0 460 Wp tolerates heat better (temp coeff -0.290%/°C vs -0.340%/°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 GM 3.0 style 360 and Solarwatt SOLARWATT Panel vision M 5.0 460 Wp?
Solarwatt SOLARWATT Panel vision GM 3.0 style 360 has a module efficiency of 19.40%, while Solarwatt SOLARWATT Panel vision M 5.0 460 Wp is 23.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Solarwatt SOLARWATT Panel vision GM 3.0 style 360 use vs Solarwatt SOLARWATT Panel vision M 5.0 460 Wp?
Solarwatt SOLARWATT Panel vision GM 3.0 style 360 uses PERC cells; Solarwatt SOLARWATT Panel vision M 5.0 460 Wp 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 Solarwatt SOLARWATT Panel vision GM 3.0 style 360 and Solarwatt SOLARWATT Panel vision M 5.0 460 Wp?
Solarwatt SOLARWATT Panel vision GM 3.0 style 360 has a 30 years power warranty; Solarwatt SOLARWATT Panel vision M 5.0 460 Wp 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 Solarwatt SOLARWATT Panel vision GM 3.0 style 360 and Solarwatt SOLARWATT Panel vision M 5.0 460 Wp bifacial panels?
Both Solarwatt SOLARWATT Panel vision GM 3.0 style 360 and Solarwatt SOLARWATT Panel vision M 5.0 460 Wp 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.

Every figure here is from the manufacturers' own datasheets - a dash means the value is not published, never an estimate. The thirty-year projection and the temperature scenarios are calculations from those figures, and each states its assumption above.
