VSUN VSUN430N-108BMH-DG-BB vs VSUN VSUN705N-132BMHT-DG

Q: Which panel is better: VSUN VSUN430N-108BMH-DG-BB or VSUN VSUN705N-132BMHT-DG?

According to our database: VSUN VSUN705N-132BMHT-DG has higher module efficiency (22.70% vs 22.02%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of VSUN VSUN430N-108BMH-DG-BB and VSUN VSUN705N-132BMHT-DG?

VSUN VSUN430N-108BMH-DG-BB has a module efficiency of 22.02%, while VSUN VSUN705N-132BMHT-DG is 22.70%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does VSUN VSUN430N-108BMH-DG-BB use vs VSUN VSUN705N-132BMHT-DG?

VSUN VSUN430N-108BMH-DG-BB uses TOPCon cells; VSUN VSUN705N-132BMHT-DG uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on VSUN VSUN430N-108BMH-DG-BB and VSUN VSUN705N-132BMHT-DG?

VSUN VSUN430N-108BMH-DG-BB has a 30 years power warranty; VSUN VSUN705N-132BMHT-DG 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.

Q: Are VSUN VSUN430N-108BMH-DG-BB and VSUN VSUN705N-132BMHT-DG bifacial panels?

Both VSUN VSUN430N-108BMH-DG-BB and VSUN VSUN705N-132BMHT-DG 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.

What it means on a roof

Thirty years of production

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

Cell temperature

Same temp coeff. for both panels (-0.300 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.
