According to our database: **Renesola RS9-705NG-E1** has higher module efficiency (**22.70%** vs **20.16%**); **Renesola RS9-705NG-E1** tolerates heat better (temp coeff **-0.290%/°C** vs **-0.340%/°C**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Renesola RS9-705NG-E1 and Renesola YH200W-19.5M? **Renesola RS9-705NG-E1** has a module efficiency of **22.70%**, while **Renesola YH**200 W**-19.5M** is **20.16%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Renesola RS9-705NG-E1 use vs Renesola YH200W-19.5M? **Renesola RS9-705NG-E1** uses **N-type** cells; **Renesola YH**200 W**-19.5M** 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 Renesola RS9-705NG-E1 and Renesola YH200W-19.5M? **Renesola RS9-705NG-E1** has a **30 years** power warranty; **Renesola YH**200 W**-19.5M** 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 Renesola RS9-705NG-E1 and Renesola YH200W-19.5M bifacial panels? **Renesola RS9-705NG-E1** is bifacial (captures light from both faces); **Renesola YH**200 W**-19.5M** is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath. ## Related comparisons - [Renesola RS9-705NG-E1 vs Renesola RS9-700NG-E1](https://comparepv.com/compare/renesola-rs9-705ng-e1/renesola-rs9-700ng-e1) - The same specification on paper - [Renesola RS9-705NG-E1 vs Renesola RS9-695NG-E1](https://comparepv.com/compare/renesola-rs9-705ng-e1/renesola-rs9-695ng-e1) - 3 differences, the largest is module efficiency - [Renesola RS9-705NG-E1 vs Renesola RS9-690NG-E1](https://comparepv.com/compare/renesola-rs9-705ng-e1/renesola-rs9-690ng-e1) - 3 differences, the largest is module efficiency - [Renesola RS9-705NG-E1 vs Renesola RS9-685NG-E1](https://comparepv.com/compare/renesola-rs9-705ng-e1/renesola-rs9-685ng-e1) - 3 differences, the largest is module efficiency - [Renesola YH200W-19.5M vs Renesola YH190W-19.5M](https://comparepv.com/compare/renesola-yh200w-19-5m/renesola-yh190w-19-5m) - 4 differences, the largest is module efficiency - [Renesola YH200W-19.5M vs Renesola YH180W-19.5M](https://comparepv.com/compare/renesola-yh200w-19-5m/renesola-yh180w-19-5m) - 7 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/renesola-rs9-705ng-e1/renesola-yh200w-19-5m 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.
