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 | [DAS Solar DAS-DH156NA-625W](https://comparepv.com/panel/das-solar-das-dh156na-625w) | [DAS Solar DAS-DH156NA-630W](https://comparepv.com/panel/das-solar-das-dh156na-630w) | | Manufacturer | DAS Solar | DAS Solar | | Power | 625 Wp | 630 Wp | | Efficiency | 22.40 % | 22.50 % | | Technology | TOPCon | TOPCon | ## Every compared parameter | Parameter | 625W | 630W | | --- | --- | --- | | Rated power | 625 Wp | 630 Wp | | Module efficiency | 22.40 % | 22.50 % | | Power density | 223.6 Wp/m² | 225.4 Wp/m² | | Open-circuit voltage | 55.74 V | 55.88 V | | Voltage at max power | 46.09 V | 46.26 V | | Short-circuit current | 14.27 A | 14.35 A | | Current at max power | 13.56 A | 13.62 A | | Temperature coefficient | -0.300 %/°C | -0.300 %/°C | | Dimensions | 2465x1134x30 mm | 2465x1134x30 mm | | Module area | 2.795 m² | 2.795 m² | | Weight | 34.3 kg | 34.3 kg | | Weight per kWp | 54.9 kg/kWp | 54.4 kg/kWp | | Product warranty | 15 yrs | 15 yrs | | Performance warranty | 30 yrs | 30 yrs | | Annual degradation | 0.40 %/yr | 0.40 %/yr | | Cell technology | TOPCon | TOPCon | | Cell type | Monocrystalline | Monocrystalline | | Cell count | - | - | | 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 (-0.300 %/°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, 625W:** 20,970 kWh - **Cumulative output, 630W:** 21,138 kWh - **Gap:** 168 kWh ## Output when hot | Condition | Cell temperature | 625W | 630W | Retained | | --- | --- | --- | --- | --- | | Standard test conditions | 25 °C | 625 W | 630 W | 100.0% of rated power | | Cool, bright day | 40 °C | 597 W | 602 W | 95.5% of rated power | | Typical summer roof | 55 °C | 569 W | 573 W | 91.0% of rated power | | Hot roof | 70 °C | 541 W | 545 W | 86.5% of rated power | ## Against the whole database | Measure | 625W | 630W | Out of | Note | | --- | --- | --- | --- | --- | | Efficiency | #4,774 | #4,222 | 14,005 | 630W leads by 552 places | | Power density | #4,955 | #3,907 | 14,005 | 630W leads by 1,048 places | | Heat behaviour | #6,093 | #6,093 | 14,005 | Tied - the same position in the database | | Weight | #9,266 | #8,755 | 14,005 | 630W leads by 511 places | | Warranty | #21 | #21 | 14,005 | Tied - the same position in the database | | Overall | #2,472 | #2,208 | 14,005 | 630W leads by 264 places | ## Questions ### Which panel is better: DAS Solar DAS-DH156NA-625W or DAS Solar DAS-DH156NA-630W? According to our database: **DAS Solar DAS-DH156NA-**630 W**** has higher module efficiency (**22.50%** vs **22.40%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of DAS Solar DAS-DH156NA-625W and DAS Solar DAS-DH156NA-630W? **DAS Solar DAS-DH156NA-**625 W**** has a module efficiency of **22.40%**, while **DAS Solar DAS-DH156NA-**630 W**** is **22.50%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does DAS Solar DAS-DH156NA-625W use vs DAS Solar DAS-DH156NA-630W? **DAS Solar DAS-DH156NA-**625 W**** uses **TOPCon** cells; **DAS Solar DAS-DH156NA-**630 W**** 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 DAS Solar DAS-DH156NA-625W and DAS Solar DAS-DH156NA-630W? **DAS Solar DAS-DH156NA-**625 W**** has a **30 years** power warranty; **DAS Solar DAS-DH156NA-**630 W**** 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 DAS Solar DAS-DH156NA-625W and DAS Solar DAS-DH156NA-630W bifacial panels? Both **DAS Solar DAS-DH156NA-**625 W**** and **DAS Solar DAS-DH156NA-**630 W**** 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 - [DAS Solar DAS-DH156NA-625W vs DAS Solar DAS-DH156NA-650W](https://comparepv.com/compare/das-solar-das-dh156na-625w/das-solar-das-dh156na-650w) - 4 differences, the largest is module efficiency - [DAS Solar DAS-DH156NA-625W vs DAS Solar DAS-DH156NA-645W](https://comparepv.com/compare/das-solar-das-dh156na-625w/das-solar-das-dh156na-645w) - 3 differences, the largest is module efficiency - [DAS Solar DAS-DH156NA-625W vs DAS Solar DAS-DH156NA-640W](https://comparepv.com/compare/das-solar-das-dh156na-625w/das-solar-das-dh156na-640w) - 3 differences, the largest is module efficiency - [DAS Solar DAS-DH156NA-625W vs DAS Solar DAS-DH156NA-635W](https://comparepv.com/compare/das-solar-das-dh156na-625w/das-solar-das-dh156na-635w) - 3 differences, the largest is module efficiency - [DAS Solar DAS-DH156NA-625W vs DAS Solar DAS-DH132NC-715](https://comparepv.com/compare/das-solar-das-dh156na-625w/das-solar-das-dh132nc-715) - 11 differences, the largest is rated power - [DAS Solar DAS-DH156NA-625W vs DAS Solar DAS-DH132NC-710](https://comparepv.com/compare/das-solar-das-dh156na-625w/das-solar-das-dh132nc-710) - 11 differences, the largest is rated power --- Source: https://comparepv.com/compare/das-solar-das-dh156na-625w/das-solar-das-dh156na-630w 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.
