According to our database: **Renew Photovoltaics RPS2MH72BD540** has higher module efficiency (**20.90%** vs **20.71%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Renew Photovoltaics RPS2MH72BD535 and Renew Photovoltaics RPS2MH72BD540? **Renew Photovoltaics RPS2MH72BD535** has a module efficiency of **20.71%**, while **Renew Photovoltaics RPS2MH72BD540** is **20.90%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Renew Photovoltaics RPS2MH72BD535 use vs Renew Photovoltaics RPS2MH72BD540? **Renew Photovoltaics RPS2MH72BD535** uses **PERC** cells; **Renew Photovoltaics RPS2MH72BD540** uses **PERC**. 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 Renew Photovoltaics RPS2MH72BD535 and Renew Photovoltaics RPS2MH72BD540? **Renew Photovoltaics RPS2MH72BD535** has a **30 years** power warranty; **Renew Photovoltaics RPS2MH72BD540** 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 Renew Photovoltaics RPS2MH72BD535 and Renew Photovoltaics RPS2MH72BD540 bifacial panels? Both **Renew Photovoltaics RPS2MH72BD535** and **Renew Photovoltaics RPS2MH72BD540** 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 - [Renew Photovoltaics RPS2MH72BD535 vs Renew Photovoltaics RPS2MH72BD560](https://comparepv.com/compare/renew-photovoltaics-rps2mh72bd535/renew-photovoltaics-rps2mh72bd560) - 4 differences, the largest is module efficiency - [Renew Photovoltaics RPS2MH72BD535 vs Renew Photovoltaics RPS2MH72BD555](https://comparepv.com/compare/renew-photovoltaics-rps2mh72bd535/renew-photovoltaics-rps2mh72bd555) - 4 differences, the largest is module efficiency - [Renew Photovoltaics RPS2MH72BD535 vs Renew Photovoltaics RPS2MH72BD550](https://comparepv.com/compare/renew-photovoltaics-rps2mh72bd535/renew-photovoltaics-rps2mh72bd550) - 3 differences, the largest is module efficiency - [Renew Photovoltaics RPS2MH72BD535 vs Renew Photovoltaics RPS2MH72BD545](https://comparepv.com/compare/renew-photovoltaics-rps2mh72bd535/renew-photovoltaics-rps2mh72bd545) - 3 differences, the largest is module efficiency - [Renew Photovoltaics RPS2MH72BD535 vs Renew Photovoltaics RPS2MH72BD530](https://comparepv.com/compare/renew-photovoltaics-rps2mh72bd535/renew-photovoltaics-rps2mh72bd530) - The same specification on paper - [Renew Photovoltaics RPS2MH72BD535 vs Renew Photovoltaics RPS3MH66BDXXX](https://comparepv.com/compare/renew-photovoltaics-rps2mh72bd535/renew-photovoltaics-rps3mh66bdxxx) - 14 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/renew-photovoltaics-rps2mh72bd535/renew-photovoltaics-rps2mh72bd540 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.
