What it means on a roof
Thirty years of production
A 1.0% first-year loss then 0.40% a year, assumed for both panels, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.310 %/°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: Axitec AC-575TGB/144TS or Axitec AC-590TB/144TS?
According to our database: Axitec AC-590TB/144TS has higher module efficiency (22.84% vs 22.26%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Axitec AC-575TGB/144TS and Axitec AC-590TB/144TS?
Axitec AC-575TGB/144TS has a module efficiency of 22.26%, while Axitec AC-590TB/144TS is 22.84%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Axitec AC-575TGB/144TS use vs Axitec AC-590TB/144TS?
Axitec AC-575TGB/144TS uses TOPCon cells; Axitec AC-590TB/144TS 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 Axitec AC-575TGB/144TS and Axitec AC-590TB/144TS?
Axitec AC-575TGB/144TS has a 30 years power warranty; Axitec AC-590TB/144TS 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 Axitec AC-575TGB/144TS and Axitec AC-590TB/144TS bifacial panels?
Both Axitec AC-575TGB/144TS and Axitec AC-590TB/144TS are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
