According to our database: **Phono Solar PS730M13GFH-22/WSHW** has higher module efficiency (**23.50%** vs **23.27%**); **Phono Solar PS730M13GFH-22/WSHW** tolerates heat better (temp coeff **-0.240%/°C** vs **-0.260%/°C**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Phono Solar PS730M13GFH-22/WSHW and Phono Solar PS475L7GFH-18/VBH? **Phono Solar PS730M13GFH-22/WSHW** has a module efficiency of **23.50%**, 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 PS730M13GFH-22/WSHW use vs Phono Solar PS475L7GFH-18/VBH? **Phono Solar PS730M13GFH-22/WSHW** uses **HJT** 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 PS730M13GFH-22/WSHW and Phono Solar PS475L7GFH-18/VBH? **Phono Solar PS730M13GFH-22/WSHW** has a **30 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 PS730M13GFH-22/WSHW and Phono Solar PS475L7GFH-18/VBH bifacial panels? Both **Phono Solar PS730M13GFH-22/WSHW** and **Phono Solar PS475L7GFH-18/VBH** 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. ## Related comparisons - [Phono Solar PS730M13GFH-22/WSHW vs Phono Solar PS725M13GFH-22/WSHW](https://comparepv.com/compare/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps730m13gfh-22-wshw/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps725m13gfh-22-wshw) - The same specification on paper - [Phono Solar PS730M13GFH-22/WSHW vs Phono Solar PS720M13GFH-22/WSHW](https://comparepv.com/compare/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps730m13gfh-22-wshw/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps720m13gfh-22-wshw) - 3 differences, the largest is module efficiency - [Phono Solar PS730M13GFH-22/WSHW vs Phono Solar PS715M13GFH-22/WSHW](https://comparepv.com/compare/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps730m13gfh-22-wshw/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps715m13gfh-22-wshw) - 3 differences, the largest is module efficiency - [Phono Solar PS730M13GFH-22/WSHW vs Phono Solar PS710M13GFH-22/WSHW](https://comparepv.com/compare/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps730m13gfh-22-wshw/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps710m13gfh-22-wshw) - 3 differences, the largest is module efficiency - [Phono Solar PS730M13GFH-22/WSHW vs Phono Solar NS-730MH-132](https://comparepv.com/compare/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps730m13gfh-22-wshw/phono-solar-ns-730mh-132) - 7 differences, the largest is temperature coefficient - [Phono Solar PS730M13GFH-22/WSHW vs Phono Solar NS-720MH-132](https://comparepv.com/compare/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps730m13gfh-22-wshw/phono-solar-ns-720mh-132) - 10 differences, the largest is temperature coefficient --- Source: https://comparepv.com/compare/phono-solar-co-ltd-phono-solar-technology-co-ltd-ps730m13gfh-22-wshw/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.
