What it means on a roof
Thirty years of production
Declared first-year losses, with 0.40% a year afterwards assumed for both panels, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.340 %/°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: Renesola YH180W-19.5M or Renesola YH190W-19.5M?
According to our database: Renesola YH190 W-19.5M has higher module efficiency (19.15% vs 18.15%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Renesola YH180W-19.5M and Renesola YH190W-19.5M?
Renesola YH180 W-19.5M has a module efficiency of 18.15%, while Renesola YH190 W-19.5M is 19.15%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Renesola YH180W-19.5M use vs Renesola YH190W-19.5M?
Renesola YH180 W-19.5M uses TOPCon cells; Renesola YH190 W-19.5M 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 Renesola YH180W-19.5M and Renesola YH190W-19.5M?
Renesola YH180 W-19.5M has a 30 years power warranty; Renesola YH190 W-19.5M 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.
