Avaada AVN66G12RTB vs Avaada AVN66G12G

Q: Which panel is better: Avaada AVN66G12RTB or Avaada AVN66G12G?

According to our database: Avaada AVN66G12RTB has higher module efficiency (23.30% vs 23.18%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Avaada AVN66G12RTB and Avaada AVN66G12G?

Avaada AVN66G12RTB has a module efficiency of 23.30%, while Avaada AVN66G12G is 23.18%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Avaada AVN66G12RTB use vs Avaada AVN66G12G?

Avaada AVN66G12RTB uses TOPCon cells; Avaada AVN66G12G uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on Avaada AVN66G12RTB and Avaada AVN66G12G?

Avaada AVN66G12RTB has a 30 years power warranty; Avaada AVN66G12G 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.

Q: Are Avaada AVN66G12RTB and Avaada AVN66G12G bifacial panels?

Both Avaada AVN66G12RTB and Avaada AVN66G12G 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.

Thirty years of production

Each panel's own declared degradation curve, at 1,200 kWh/kWp a year

Cell temperature

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.
