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.

Which panel is better: Sunpro Power SPDG600-N144M10 or Sunpro Power SPDG585-N144M10?
According to our database: Sunpro Power SPDG600-N144M10 has higher module efficiency (23.22% vs 22.64%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Sunpro Power SPDG600-N144M10 and Sunpro Power SPDG585-N144M10?
Sunpro Power SPDG600-N144M10 has a module efficiency of 23.22%, while Sunpro Power SPDG585-N144M10 is 22.64%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Sunpro Power SPDG600-N144M10 use vs Sunpro Power SPDG585-N144M10?
Sunpro Power SPDG600-N144M10 uses TOPCon cells; Sunpro Power SPDG585-N144M10 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 Sunpro Power SPDG600-N144M10 and Sunpro Power SPDG585-N144M10?
Sunpro Power SPDG600-N144M10 has a 30 years power warranty; Sunpro Power SPDG585-N144M10 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.
Are Sunpro Power SPDG600-N144M10 and Sunpro Power SPDG585-N144M10 bifacial panels?
Sunpro Power SPDG600-N144M10 is bifacial (captures light from both faces); Sunpro Power SPDG585-N144M10 is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
