Two records this alike are usually one panel sold under two names, or two bins of the same production line - decide on price and on who you would rather buy from. ## The two panels | Attribute | A | B | | --- | --- | --- | | Panel | [Sunplus SR5-60HBD-585M](https://comparepv.com/panel/sunplus-sr5-60hbd-585m) | [Sunplus SR5-60HBD-590M](https://comparepv.com/panel/sunplus-sr5-60hbd-590m) | | Manufacturer | Sunplus | Sunplus | | Power | 585 Wp | 590 Wp | | Efficiency | 20.70 % | 20.80 % | | Technology | PERC | PERC | ## Every compared parameter | Parameter | 585M | 590M | | --- | --- | --- | | Rated power | 585 Wp | 590 Wp | | Module efficiency | 20.70 % | 20.80 % | | Power density | 206.7 Wp/m² | 208.5 Wp/m² | | Open-circuit voltage | 40.70 V | 40.90 V | | Voltage at max power | 34.30 V | 34.50 V | | Short-circuit current | 18.32 A | 18.37 A | | Current at max power | 17.06 A | 17.11 A | | Temperature coefficient | -0.340 %/°C | -0.340 %/°C | | Dimensions | 2172x1303x33 mm | 2172x1303x33 mm | | Module area | 2.830 m² | 2.830 m² | | Weight | 34.9 kg | 34.9 kg | | Weight per kWp | 59.7 kg/kWp | 59.2 kg/kWp | | Product warranty | - | - | | Performance warranty | 30 yrs | 30 yrs | | Annual degradation | 0.45 %/yr | 0.45 %/yr | | Cell technology | PERC | PERC | | Cell type | Monocrystalline | Monocrystalline | | Cell count | 120 | 120 | | Bifacial | Yes | Yes | ## Thirty-year yield Each panel's own declared degradation curve, at 1,200 kWh/kWp a year Same temp coeff. for both panels (-0.340 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other. - **Cumulative output, 585M:** 19,265 kWh - **Cumulative output, 590M:** 19,429 kWh - **Gap:** 164 kWh ## Output when hot | Condition | Cell temperature | 585M | 590M | Retained | | --- | --- | --- | --- | --- | | Standard test conditions | 25 °C | 585 W | 590 W | 100.0% of rated power | | Cool, bright day | 40 °C | 555 W | 560 W | 94.9% of rated power | | Typical summer roof | 55 °C | 525 W | 530 W | 89.8% of rated power | | Hot roof | 70 °C | 495 W | 500 W | 84.7% of rated power | ## Against the whole database | Measure | 585M | 590M | Out of | Note | | --- | --- | --- | --- | --- | | Efficiency | #10,764 | #10,457 | 14,005 | 590M leads by 307 places | | Power density | #10,926 | #10,359 | 14,005 | 590M leads by 567 places | | Heat behaviour | #8,778 | #8,778 | 14,005 | Tied - the same position in the database | | Weight | #12,228 | #12,036 | 14,005 | 590M leads by 192 places | | Warranty | #21 | #21 | 14,005 | Tied - the same position in the database | | Overall | #9,089 | #8,838 | 14,005 | 590M leads by 251 places | ## Questions ### Which panel is better: Sunplus SR5-60HBD-585M or Sunplus SR5-60HBD-590M? According to our database: **Sunplus SR5-60HBD-590M** has higher module efficiency (**20.80%** vs **20.70%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Sunplus SR5-60HBD-585M and Sunplus SR5-60HBD-590M? **Sunplus SR5-60HBD-585M** has a module efficiency of **20.70%**, while **Sunplus SR5-60HBD-590M** is **20.80%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Sunplus SR5-60HBD-585M use vs Sunplus SR5-60HBD-590M? **Sunplus SR5-60HBD-585M** uses **PERC** cells; **Sunplus SR5-60HBD-590M** 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-585M and Sunplus SR5-60HBD-590M? **Sunplus SR5-60HBD-585M** has a **30 years** power warranty; **Sunplus SR5-60HBD-590M** 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-585M and Sunplus SR5-60HBD-590M bifacial panels? Both **Sunplus SR5-60HBD-585M** and **Sunplus SR5-60HBD-590M** 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-585M vs Sunplus SR5-60HBD-600M](https://comparepv.com/compare/sunplus-sr5-60hbd-585m/sunplus-sr5-60hbd-600m) - 3 differences, the largest is module efficiency - [Sunplus SR5-60HBD-585M vs Sunplus SR5-60HBD-595M](https://comparepv.com/compare/sunplus-sr5-60hbd-585m/sunplus-sr5-60hbd-595m) - 3 differences, the largest is module efficiency - [Sunplus SR5-60HBD-585M vs Sunplus SR5-60HBD-580M](https://comparepv.com/compare/sunplus-sr5-60hbd-585m/sunplus-sr5-60hbd-580m) - One difference: module efficiency - [Sunplus SR5-60HBD-585M vs Sunplus 750](https://comparepv.com/compare/sunplus-sr5-60hbd-585m/sunplus-750) - 14 differences, the largest is module efficiency - [Sunplus SR5-60HBD-585M vs Sunplus 745](https://comparepv.com/compare/sunplus-sr5-60hbd-585m/sunplus-745) - 14 differences, the largest is module efficiency - [Sunplus SR5-60HBD-585M vs Sunplus 740](https://comparepv.com/compare/sunplus-sr5-60hbd-585m/sunplus-740) - 14 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/sunplus-sr5-60hbd-585m/sunplus-sr5-60hbd-590m 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.
