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 | [AE Solar CMD-108BDE-435W](https://comparepv.com/panel/ae-solar-cmd-108bde-435w) | [AE Solar CMD-108BDS-435W](https://comparepv.com/panel/ae-solar-cmd-108bds-435w) | | Manufacturer | AE Solar | AE Solar | | Power | 435 Wp | 435 Wp | | Efficiency | 22.31 % | 22.31 % | | Technology | TOPCon | TOPCon | ## Every compared parameter | Parameter | 108BDE-435W | 108BDS-435W | | --- | --- | --- | | Rated power | 435 Wp | 435 Wp | | Module efficiency | 22.31 % | 22.31 % | | Power density | 223.1 Wp/m² | 223.1 Wp/m² | | Open-circuit voltage | 38.66 V | 38.46 V | | Voltage at max power | 32.84 V | 32.64 V | | Short-circuit current | 14.06 A | 14.23 A | | Current at max power | 13.25 A | 13.33 A | | Temperature coefficient | -0.290 %/°C | -0.290 %/°C | | Dimensions | 1721x1133x30 mm | 1721x1133x30 mm | | Module area | 1.950 m² | 1.950 m² | | Weight | 23.5 kg | 23.5 kg | | Weight per kWp | 54.0 kg/kWp | 54.0 kg/kWp | | Product warranty | 30 yrs | 30 yrs | | Performance warranty | 30 yrs | 30 yrs | | Annual degradation | - | - | | Cell technology | TOPCon | TOPCon | | Cell type | Monocrystalline | Monocrystalline | | Cell count | 108 | 108 | | Bifacial | Yes | Yes | ## Thirty-year yield A 1.0% first-year loss then 0.40% a year, assumed for both panels, at 1,200 kWh/kWp a year Same temp coeff. for both panels (-0.290 %/°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, 108BDE-435W:** 14,595 kWh - **Cumulative output, 108BDS-435W:** 14,595 kWh - **Gap:** No difference ## Output when hot | Condition | Cell temperature | 108BDE-435W | 108BDS-435W | Retained | | --- | --- | --- | --- | --- | | Standard test conditions | 25 °C | 435 W | 435 W | 100.0% of rated power | | Cool, bright day | 40 °C | 416 W | 416 W | 95.7% of rated power | | Typical summer roof | 55 °C | 397 W | 397 W | 91.3% of rated power | | Hot roof | 70 °C | 378 W | 378 W | 87.0% of rated power | ## Against the whole database | Measure | 108BDE-435W | 108BDS-435W | Out of | Note | | --- | --- | --- | --- | --- | | Efficiency | #5,082 | #5,082 | 14,005 | Tied - the same position in the database | | Power density | #5,070 | #5,070 | 14,005 | Tied - the same position in the database | | Heat behaviour | #2,165 | #2,165 | 14,005 | Tied - the same position in the database | | Weight | #8,229 | #8,229 | 14,005 | Tied - the same position in the database | | Warranty | #21 | #21 | 14,005 | Tied - the same position in the database | | Overall | #5,914 | #5,914 | 14,005 | Tied - the same position in the database | ## Questions ### Which panel is better: AE Solar CMD-108BDE-435W or AE Solar CMD-108BDS-435W? According to our database: both panels are closely matched on key specs - the decision often comes down to price and local availability. See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of AE Solar CMD-108BDE-435W and AE Solar CMD-108BDS-435W? **AE Solar CMD-108BDE-**435 W**** has a module efficiency of **22.31%**, while **AE Solar CMD-108BDS-**435 W**** is **22.31%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does AE Solar CMD-108BDE-435W use vs AE Solar CMD-108BDS-435W? **AE Solar CMD-108BDE-**435 W**** uses **TOPCon** cells; **AE Solar CMD-108BDS-**435 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 AE Solar CMD-108BDE-435W and AE Solar CMD-108BDS-435W? **AE Solar CMD-108BDE-**435 W**** has a **30 years** power warranty; **AE Solar CMD-108BDS-**435 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 AE Solar CMD-108BDE-435W and AE Solar CMD-108BDS-435W bifacial panels? Both **AE Solar CMD-108BDE-**435 W**** and **AE Solar CMD-108BDS-**435 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 - [AE Solar CMD-108BDE-435W vs AE Solar CMD-108BDE-430W](https://comparepv.com/compare/ae-solar-cmd-108bde-435w/ae-solar-cmd-108bde-430w) - One difference: module efficiency - [AE Solar CMD-108BDE-435W vs AE Solar CMD-108BDE-425W](https://comparepv.com/compare/ae-solar-cmd-108bde-435w/ae-solar-cmd-108bde-425w) - 3 differences, the largest is module efficiency - [AE Solar CMD-108BDE-435W vs AE Solar CMD-108BDE-420W](https://comparepv.com/compare/ae-solar-cmd-108bde-435w/ae-solar-cmd-108bde-420w) - 3 differences, the largest is module efficiency - [AE Solar CMD-108BDE-435W vs AE Solar CMD-108BDE-415W](https://comparepv.com/compare/ae-solar-cmd-108bde-435w/ae-solar-cmd-108bde-415w) - 4 differences, the largest is module efficiency - [AE Solar CMD-108BDS-435W vs AE Solar CMD-108BDS-440W](https://comparepv.com/compare/ae-solar-cmd-108bds-435w/ae-solar-cmd-108bds-440w) - One difference: module efficiency - [AE Solar CMD-108BDS-435W vs AE Solar AE CMD-108BDS-440](https://comparepv.com/compare/ae-solar-cmd-108bds-435w/ae-solar-ae-cmd-108bds-440) - One difference: module efficiency --- Source: https://comparepv.com/compare/ae-solar-cmd-108bde-435w/ae-solar-cmd-108bds-435w 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.
