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 (-0.430 %/°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: Peimar SG325P or Peimar SG330P?
According to our database: Peimar SG330P has higher module efficiency (17.00% vs 16.74%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Peimar SG325P and Peimar SG330P?
Peimar SG325P has a module efficiency of 16.74%, while Peimar SG330P is 17.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Peimar SG325P use vs Peimar SG330P?
Peimar SG325P uses PERC cells; Peimar SG330P uses PERC. 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 Peimar SG325P and Peimar SG330P?
Peimar SG325P has a 30 years power warranty; Peimar SG330P 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.
