The verdict

Identical on every published parameter

All 18 comparable parameters agree, with 1 more left out because at least one datasheet does not publish it. Two records this alike are usually one panel sold under two names, or two bins of the same production line - decide on price and on who you would rather buy from.

What it means on a roof

Thirty years of production
A 1.0% first-year loss then 0.40% a year, assumed for both panels, 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: Solarwatt SOLARWATT Panel vision M 5.0 445 Wp or Solarwatt SOLARWATT Panel vision M 5.0 445Wp?
According to our database: both panels are closely matched on key specs - the decision often comes down to price and local availability. 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 5.0 445 Wp and Solarwatt SOLARWATT Panel vision M 5.0 445Wp?
Solarwatt SOLARWATT Panel vision M 5.0 445 Wp has a module efficiency of 22.30%, while Solarwatt SOLARWATT Panel vision M 5.0 445 Wp is 22.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Solarwatt SOLARWATT Panel vision M 5.0 445 Wp use vs Solarwatt SOLARWATT Panel vision M 5.0 445Wp?
Solarwatt SOLARWATT Panel vision M 5.0 445 Wp uses TOPCon cells; Solarwatt SOLARWATT Panel vision M 5.0 445 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 M 5.0 445 Wp and Solarwatt SOLARWATT Panel vision M 5.0 445Wp?
Solarwatt SOLARWATT Panel vision M 5.0 445 Wp has a 30 years power warranty; Solarwatt SOLARWATT Panel vision M 5.0 445 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 M 5.0 445 Wp and Solarwatt SOLARWATT Panel vision M 5.0 445Wp bifacial panels?
Both Solarwatt SOLARWATT Panel vision M 5.0 445 Wp and Solarwatt SOLARWATT Panel vision M 5.0 445 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.
