Questions about this pairing
Which panel is better: Renew Photovoltaics RPS1MH60MBXXX or Renew Photovoltaics RPS3MH66BDXXX?
According to our database: Renew Photovoltaics RPS3MH66BDXXX has higher module efficiency (23.69% vs 21.49%); Renew Photovoltaics RPS3MH66BDXXX tolerates heat better (temp coeff -0.290%/°C vs -0.330%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Renew Photovoltaics RPS1MH60MBXXX and Renew Photovoltaics RPS3MH66BDXXX?
Renew Photovoltaics RPS1MH60MBXXX has a module efficiency of 21.49%, while Renew Photovoltaics RPS3MH66BDXXX is 23.69%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Renew Photovoltaics RPS1MH60MBXXX use vs Renew Photovoltaics RPS3MH66BDXXX?
Renew Photovoltaics RPS1MH60MBXXX uses PERC cells; Renew Photovoltaics RPS3MH66BDXXX 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 Renew Photovoltaics RPS1MH60MBXXX and Renew Photovoltaics RPS3MH66BDXXX?
Renew Photovoltaics RPS1MH60MBXXX has a 25 years power warranty; Renew Photovoltaics RPS3MH66BDXXX 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 Renew Photovoltaics RPS1MH60MBXXX and Renew Photovoltaics RPS3MH66BDXXX bifacial panels?
Renew Photovoltaics RPS3MH66BDXXX is bifacial (captures light from both faces); Renew Photovoltaics RPS1MH60MBXXX is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
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.
