Questions about this pairing
Which panel is better: Trina Solar TSM-DE09R.08-435 or Maxeon SPR-MAX3-430-R?
According to our database: Maxeon SPR-MAX3-430-R has higher module efficiency (22.70% vs 21.80%); Maxeon SPR-MAX3-430-R tolerates heat better (temp coeff -0.270%/°C vs -0.340%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Trina Solar TSM-DE09R.08-435 and Maxeon SPR-MAX3-430-R?
Trina Solar TSM-DE09R.08-435 has a module efficiency of 21.80%, while Maxeon SPR-MAX3-430-R is 22.70%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Trina Solar TSM-DE09R.08-435 use vs Maxeon SPR-MAX3-430-R?
Trina Solar TSM-DE09R.08-435 uses PERC cells; Maxeon SPR-MAX3-430-R uses Back Contact. 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 Trina Solar TSM-DE09R.08-435 and Maxeon SPR-MAX3-430-R?
Trina Solar TSM-DE09R.08-435 has a 25 years power warranty; Maxeon SPR-MAX3-430-R has a 40 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.
