According to our database: **Phono Solar PS630L8GFH-22/WNH** has higher module efficiency (**23.32%** vs **22.70%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Phono Solar PS630L8GFH-22/WNH and Phono Solar PS705M13GFH-22/WNH? **Phono Solar PS630L8GFH-22/WNH** has a module efficiency of **23.32%**, while **Phono Solar PS705M13GFH-22/WNH** is **22.70%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Phono Solar PS630L8GFH-22/WNH use vs Phono Solar PS705M13GFH-22/WNH? **Phono Solar PS630L8GFH-22/WNH** uses **TOPCon** cells; **Phono Solar PS705M13GFH-22/WNH** 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 Phono Solar PS630L8GFH-22/WNH and Phono Solar PS705M13GFH-22/WNH? **Phono Solar PS630L8GFH-22/WNH** has a **30 years** power warranty; **Phono Solar PS705M13GFH-22/WNH** 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 PS630L8GFH-22/WNH and Phono Solar PS705M13GFH-22/WNH bifacial panels? Both **Phono Solar PS630L8GFH-22/WNH** and **Phono Solar PS705M13GFH-22/WNH** 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 PS630L8GFH-22/WNH vs Phono Solar PS710M13GFH-22/WNH](https://comparepv.com/compare/phono-solar-ps630l8gfh-22-wnh/phono-solar-technology-co-ltd-ps710m13gfh-22-wnh) - 10 differences, the largest is rated power - [Phono Solar PS630L8GFH-22/WNH vs Phono Solar PS700M13GFH-22/WNH](https://comparepv.com/compare/phono-solar-ps630l8gfh-22-wnh/phono-solar-technology-co-ltd-ps700m13gfh-22-wnh) - 11 differences, the largest is module efficiency - [Phono Solar PS630L8GFH-22/WNH vs Phono Solar PS695M13GFH-22/WNH](https://comparepv.com/compare/phono-solar-ps630l8gfh-22-wnh/phono-solar-technology-co-ltd-ps695m13gfh-22-wnh) - 11 differences, the largest is module efficiency - [Phono Solar PS630L8GFH-22/WNH vs Phono Solar PS690M13GFH-22/WNH](https://comparepv.com/compare/phono-solar-ps630l8gfh-22-wnh/phono-solar-technology-co-ltd-ps690m13gfh-22-wnh) - 11 differences, the largest is module efficiency - [Phono Solar PS630L8GFH-22/WNH vs Phono Solar PS630L8GF-22/WNH](https://comparepv.com/compare/phono-solar-ps630l8gfh-22-wnh/phono-solar-ps630l8gf-22-wnh) - The same specification on paper - [Phono Solar PS630L8GFH-22/WNH vs Phono Solar PS625L8GF-22/WNH](https://comparepv.com/compare/phono-solar-ps630l8gfh-22-wnh/phono-solar-ps625l8gf-22-wnh) - The same specification on paper --- Source: https://comparepv.com/compare/phono-solar-ps630l8gfh-22-wnh/phono-solar-technology-co-ltd-ps705m13gfh-22-wnh 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.
