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 (-0.290 %/°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: Ulica Solar UL-505M-120BDGN or Ulica Solar UL-705M-132DGN?
According to our database: Ulica Solar UL-505M-120BDGN has higher module efficiency (22.81% vs 22.70%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Ulica Solar UL-505M-120BDGN and Ulica Solar UL-705M-132DGN?
Ulica Solar UL-505M-120BDGN has a module efficiency of 22.81%, while Ulica Solar UL-705M-132DGN is 22.70%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Ulica Solar UL-505M-120BDGN use vs Ulica Solar UL-705M-132DGN?
Ulica Solar UL-505M-120BDGN uses TOPCon cells; Ulica Solar UL-705M-132DGN 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 Ulica Solar UL-505M-120BDGN and Ulica Solar UL-705M-132DGN?
Ulica Solar UL-505M-120BDGN has a 30 years power warranty; Ulica Solar UL-705M-132DGN 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 Ulica Solar UL-505M-120BDGN and Ulica Solar UL-705M-132DGN bifacial panels?
Both Ulica Solar UL-505M-120BDGN and Ulica Solar UL-705M-132DGN 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.
