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 (-0.240 %/°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: Risen RSM132-8-700-715BHDG-705 or Risen RSM132-8-700-715BHDG (710W)?
According to our database: Risen RSM132-8-700-715BHDG (710 W) has higher module efficiency (22.90% vs 22.70%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Risen RSM132-8-700-715BHDG-705 and Risen RSM132-8-700-715BHDG (710W)?
Risen RSM132-8-700-715BHDG-705 has a module efficiency of 22.70%, while Risen RSM132-8-700-715BHDG (710 W) is 22.90%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Risen RSM132-8-700-715BHDG-705 use vs Risen RSM132-8-700-715BHDG (710W)?
Risen RSM132-8-700-715BHDG-705 uses HJT cells; Risen RSM132-8-700-715BHDG (710 W) uses HJT. 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 Risen RSM132-8-700-715BHDG-705 and Risen RSM132-8-700-715BHDG (710W)?
Risen RSM132-8-700-715BHDG-705 has a 30 years power warranty; Risen RSM132-8-700-715BHDG (710 W) 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 Risen RSM132-8-700-715BHDG-705 and Risen RSM132-8-700-715BHDG (710W) bifacial panels?
Both Risen RSM132-8-700-715BHDG-705 and Risen RSM132-8-700-715BHDG (710 W) 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.
