According to our database: **Sunplus SR5-60HBD-595M** has higher module efficiency (**21.00%** vs **20.80%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Sunplus SR5-60HBD-590M and Sunplus SR5-60HBD-595M? **Sunplus SR5-60HBD-590M** has a module efficiency of **20.80%**, while **Sunplus SR5-60HBD-595M** is **21.00%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Sunplus SR5-60HBD-590M use vs Sunplus SR5-60HBD-595M? **Sunplus SR5-60HBD-590M** uses **PERC** cells; **Sunplus SR5-60HBD-595M** 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 Sunplus SR5-60HBD-590M and Sunplus SR5-60HBD-595M? **Sunplus SR5-60HBD-590M** has a **30 years** power warranty; **Sunplus SR5-60HBD-595M** 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 Sunplus SR5-60HBD-590M and Sunplus SR5-60HBD-595M bifacial panels? Both **Sunplus SR5-60HBD-590M** and **Sunplus SR5-60HBD-595M** 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 - [Sunplus SR5-60HBD-590M vs Sunplus SR5-60HBD-600M](https://comparepv.com/compare/sunplus-sr5-60hbd-590m/sunplus-sr5-60hbd-600m) - 3 differences, the largest is module efficiency - [Sunplus SR5-60HBD-590M vs Sunplus SR5-60HBD-585M](https://comparepv.com/compare/sunplus-sr5-60hbd-590m/sunplus-sr5-60hbd-585m) - The same specification on paper - [Sunplus SR5-60HBD-590M vs Sunplus SR5-60HBD-580M](https://comparepv.com/compare/sunplus-sr5-60hbd-590m/sunplus-sr5-60hbd-580m) - 3 differences, the largest is module efficiency - [Sunplus SR5-60HBD-590M vs Sunplus 750](https://comparepv.com/compare/sunplus-sr5-60hbd-590m/sunplus-750) - 14 differences, the largest is module efficiency - [Sunplus SR5-60HBD-590M vs Sunplus 745](https://comparepv.com/compare/sunplus-sr5-60hbd-590m/sunplus-745) - 14 differences, the largest is module efficiency - [Sunplus SR5-60HBD-590M vs Sunplus 740](https://comparepv.com/compare/sunplus-sr5-60hbd-590m/sunplus-740) - 14 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/sunplus-sr5-60hbd-590m/sunplus-sr5-60hbd-595m 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.
