What it means on a roof
Thirty years of production
Declared annual degradation, with a 1.0% first-year loss assumed for both panels because at least one datasheet omits it, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.350 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Which panel is better: Resun Solar RS8V430M-FB or Resun Solar RS8V435M-FB?
According to our database: Resun Solar RS8V435M-FB 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 RS8V430M-FB and Resun Solar RS8V435M-FB?
Resun Solar RS8V430M-FB has a module efficiency of 22.02%, while Resun Solar RS8V435M-FB is 22.28%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Resun Solar RS8V430M-FB use vs Resun Solar RS8V435M-FB?
Resun Solar RS8V430M-FB uses TOPCon cells; Resun Solar RS8V435M-FB 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 RS8V430M-FB and Resun Solar RS8V435M-FB?
Resun Solar RS8V430M-FB has a 30 years power warranty; Resun Solar RS8V435M-FB 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.
