Questions about this pairing

Which panel is better: Resun Solar RS8V-M-435W FULL BLACK or Resun Solar RS8V-M TOPCON-435W?
According to our database: Resun Solar RS8V-M-435 W FULL BLACK tolerates heat better (temp coeff -0.250%/°C vs -0.300%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Resun Solar RS8V-M-435W FULL BLACK and Resun Solar RS8V-M TOPCON-435W?
Resun Solar RS8V-M-435 W FULL BLACK has a module efficiency of 22.28%, 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-435W FULL BLACK use vs Resun Solar RS8V-M TOPCON-435W?
Resun Solar RS8V-M-435 W FULL BLACK 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-435W FULL BLACK and Resun Solar RS8V-M TOPCON-435W?
Resun Solar RS8V-M-435 W FULL BLACK 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.
