What it means on a roof

Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.300 %/°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: Resun Solar RS8V-M TOPCON-430W or Resun Solar RS8V-M TOPCON-435W?
According to our database: Resun Solar RS8V-M TOPCON-435 W has higher module efficiency (22.28% vs 22.02%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Resun Solar RS8V-M TOPCON-430W and Resun Solar RS8V-M TOPCON-435W?
Resun Solar RS8V-M TOPCON-430 W has a module efficiency of 22.02%, while Resun Solar RS8V-M TOPCON-435 W is 22.28%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Resun Solar RS8V-M TOPCON-430W use vs Resun Solar RS8V-M TOPCON-435W?
Resun Solar RS8V-M TOPCON-430 W uses TOPCon cells; Resun Solar RS8V-M TOPCON-435 W 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 Resun Solar RS8V-M TOPCON-430W and Resun Solar RS8V-M TOPCON-435W?
Resun Solar RS8V-M TOPCON-430 W has a 30 years power warranty; Resun Solar RS8V-M TOPCON-435 W 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.

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.
