Questions about this pairing

Which panel is better: Goldi Solar GS12R-T132-GF-620 or Goldi Solar GS12-T132-GF-715?
According to our database: Goldi Solar GS12-T132-GF-715 has higher module efficiency (23.01% vs 22.95%); Goldi Solar GS12-T132-GF-715 tolerates heat better (temp coeff -0.280%/°C vs -0.300%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Goldi Solar GS12R-T132-GF-620 and Goldi Solar GS12-T132-GF-715?
Goldi Solar GS12R-T132-GF-620 has a module efficiency of 22.95%, while Goldi Solar GS12-T132-GF-715 is 23.01%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Goldi Solar GS12R-T132-GF-620 use vs Goldi Solar GS12-T132-GF-715?
Goldi Solar GS12R-T132-GF-620 uses TOPCon cells; Goldi Solar GS12-T132-GF-715 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 Goldi Solar GS12R-T132-GF-620 and Goldi Solar GS12-T132-GF-715?
Goldi Solar GS12R-T132-GF-620 has a 30 years power warranty; Goldi Solar GS12-T132-GF-715 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 Goldi Solar GS12R-T132-GF-620 and Goldi Solar GS12-T132-GF-715 bifacial panels?
Both Goldi Solar GS12R-T132-GF-620 and Goldi Solar GS12-T132-GF-715 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.

Every figure here is from the manufacturers' own datasheets - a dash means the value is not published, never an estimate. The thirty-year projection and the temperature scenarios are calculations from those figures, and each states its assumption above.
