According to our database: **Phono Solar PS475L7GFH-18/VBH** has higher module efficiency (**23.27%** vs **23.17%**); **Phono Solar PS475L7GFH-18/VBH** tolerates heat better (temp coeff **-0.260%/°C** vs **-0.290%/°C**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Phono Solar NS-720MH-132 and Phono Solar PS475L7GFH-18/VBH? **Phono Solar NS-720MH-132** has a module efficiency of **23.17%**, while **Phono Solar PS475L7GFH-18/VBH** is **23.27%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Phono Solar NS-720MH-132 use vs Phono Solar PS475L7GFH-18/VBH? **Phono Solar NS-720MH-132** uses **N-type** cells; **Phono Solar PS475L7GFH-18/VBH** uses **Back Contact**. 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 Phono Solar NS-720MH-132 and Phono Solar PS475L7GFH-18/VBH? **Phono Solar NS-720MH-132** has a **25 years** power warranty; **Phono Solar PS475L7GFH-18/VBH** 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 Phono Solar NS-720MH-132 and Phono Solar PS475L7GFH-18/VBH bifacial panels? **Phono Solar PS475L7GFH-18/VBH** is bifacial (captures light from both faces); **Phono Solar NS-720MH-132** is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath. ## Related comparisons - [Phono Solar NS-720MH-132 vs Phono Solar NS-730MH-132](https://comparepv.com/compare/phono-solar-ns-720mh-132/phono-solar-ns-730mh-132) - 3 differences, the largest is module efficiency - [Phono Solar NS-720MH-132 vs Phono Solar NS-710MH-132](https://comparepv.com/compare/phono-solar-ns-720mh-132/phono-solar-ns-710mh-132) - 3 differences, the largest is module efficiency - [Phono Solar NS-720MH-132 vs Phono Solar NS-700MH-132](https://comparepv.com/compare/phono-solar-ns-720mh-132/phono-solar-ns-700mh-132) - 3 differences, the largest is module efficiency - [Phono Solar NS-720MH-132 vs Phono Solar NS-690MH-132](https://comparepv.com/compare/phono-solar-ns-720mh-132/phono-solar-ns-690mh-132) - 5 differences, the largest is module efficiency - [Phono Solar NS-720MH-132 vs Phono Solar NS-670MH-132](https://comparepv.com/compare/phono-solar-ns-720mh-132/phono-solar-ns-670mh-132) - 10 differences, the largest is module efficiency - [Phono Solar NS-720MH-132 vs Phono Solar NS-665MH-132](https://comparepv.com/compare/phono-solar-ns-720mh-132/phono-solar-ns-665mh-132) - 10 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/phono-solar-ns-720mh-132/phono-solar-ps475l7gfh-18-vbh Not in this file, on the page: the thirty-year yield curve year by year at a cell temperature you pick and a written summary generated on request.
