## Thirty-year yield

Each panel's own declared degradation curve, at 1,200 kWh/kWp a year

Same temp coeff. for both panels (-0.290 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

- **Cumulative output, CHSM66N(DG)/F-BH-710:** 23,822 kWh
- **Cumulative output, CHSM66RN(DG)/F-BH-650W:** 21,809 kWh
- **Gap:** 2,013 kWh

According to our database: **Astronergy CHSM66RN(DG)/F-BH-**650 W**** has higher module efficiency (**24.10%** vs **22.90%**). See the full spec comparison and 30-year energy simulation above for a complete picture.


### What is the efficiency of Astronergy CHSM66N(DG)/F-BH-710 and Astronergy CHSM66RN(DG)/F-BH-650W?

**Astronergy CHSM66N(DG)/F-BH-710** has a module efficiency of **22.90%**, while **Astronergy CHSM66RN(DG)/F-BH-**650 W**** is **24.10%**. Higher efficiency means more electricity from the same roof area - useful when space is limited.


### What cell technology does Astronergy CHSM66N(DG)/F-BH-710 use vs Astronergy CHSM66RN(DG)/F-BH-650W?

**Astronergy CHSM66N(DG)/F-BH-710** uses **TOPCon** cells; **Astronergy CHSM66RN(DG)/F-BH-**650 W**** 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 Astronergy CHSM66N(DG)/F-BH-710 and Astronergy CHSM66RN(DG)/F-BH-650W?

**Astronergy CHSM66N(DG)/F-BH-710** has a **30 years** power warranty; **Astronergy CHSM66RN(DG)/F-BH-**650 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 Astronergy CHSM66N(DG)/F-BH-710 and Astronergy CHSM66RN(DG)/F-BH-650W bifacial panels?

Both **Astronergy CHSM66N(DG)/F-BH-710** and **Astronergy CHSM66RN(DG)/F-BH-**650 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.
