Questions about this pairing

Which panel is better: Ulica Solar UL-665M-132DG or Ulica Solar UL-700M-132DGN?
According to our database: Ulica Solar UL-700M-132DGN has higher module efficiency (22.53% vs 21.41%); Ulica Solar UL-700M-132DGN tolerates heat better (temp coeff -0.290%/°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 Ulica Solar UL-665M-132DG and Ulica Solar UL-700M-132DGN?
Ulica Solar UL-665M-132DG has a module efficiency of 21.41%, while Ulica Solar UL-700M-132DGN is 22.53%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Ulica Solar UL-665M-132DG use vs Ulica Solar UL-700M-132DGN?
Ulica Solar UL-665M-132DG uses TOPCon cells; Ulica Solar UL-700M-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-665M-132DG and Ulica Solar UL-700M-132DGN?
Ulica Solar UL-665M-132DG has a 30 years power warranty; Ulica Solar UL-700M-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-665M-132DG and Ulica Solar UL-700M-132DGN bifacial panels?
Both Ulica Solar UL-665M-132DG and Ulica Solar UL-700M-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.
