Questions about this pairing

Which panel is better: Sunova TS-BGT66(610)-G11 or Sunova TS-BGT66(715)-G12?
According to our database: Sunova TS-BGT66(715)-G12 has higher module efficiency (23.00% vs 22.60%); Sunova TS-BGT66(610)-G11 tolerates heat better (temp coeff -0.290%/°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 Sunova TS-BGT66(610)-G11 and Sunova TS-BGT66(715)-G12?
Sunova TS-BGT66(610)-G11 has a module efficiency of 22.60%, while Sunova TS-BGT66(715)-G12 is 23.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Sunova TS-BGT66(610)-G11 use vs Sunova TS-BGT66(715)-G12?
Sunova TS-BGT66(610)-G11 uses N-type cells; Sunova TS-BGT66(715)-G12 uses N-type. 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 Sunova TS-BGT66(610)-G11 and Sunova TS-BGT66(715)-G12?
Sunova TS-BGT66(610)-G11 has a 30 years power warranty; Sunova TS-BGT66(715)-G12 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 Sunova TS-BGT66(610)-G11 and Sunova TS-BGT66(715)-G12 bifacial panels?
Both Sunova TS-BGT66(610)-G11 and Sunova TS-BGT66(715)-G12 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.
