According to our database: **AE Solar CME-132BDS-**730 W**** has higher module efficiency (**23.53%** vs **20.92%**); **AE Solar CME-132BDS-**730 W**** tolerates heat better (temp coeff **-0.290%/°C** vs **-0.350%/°C**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of AE Solar AE MD-144 530W-550W (540W) and AE Solar CME-132BDS-730W? **AE Solar AE MD-144 **530 W**-**550 W** (**540 W**)** has a module efficiency of **20.92%**, while **AE Solar CME-132BDS-**730 W**** is **23.53%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does AE Solar AE MD-144 530W-550W (540W) use vs AE Solar CME-132BDS-730W? **AE Solar AE MD-144 **530 W**-**550 W** (**540 W**)** uses **PERC** cells; **AE Solar CME-132BDS-**730 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 AE MD-144 530W-550W (540W) and AE Solar CME-132BDS-730W? **AE Solar AE MD-144 **530 W**-**550 W** (**540 W**)** has a **30 years** power warranty; **AE Solar CME-132BDS-**730 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 AE MD-144 530W-550W (540W) and AE Solar CME-132BDS-730W bifacial panels? **AE Solar CME-132BDS-**730 W**** is bifacial (captures light from both faces); **AE Solar AE MD-144 **530 W**-**550 W** (**540 W**)** is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath. ## Related comparisons - [AE Solar AE MD-144 530W-550W (540W) vs AE Solar AE MD-144 530W-550W (550W)](https://comparepv.com/compare/ae-solar-ae-md-144-530w-550w-540w/ae-solar-ae-md-144-530w-550w-550w) - 4 differences, the largest is module efficiency - [AE Solar AE MD-144 530W-550W (540W) vs AE Solar AE MD-144 530W-550W (545W)](https://comparepv.com/compare/ae-solar-ae-md-144-530w-550w-540w/ae-solar-ae-md-144-530w-550w-545w) - One difference: module efficiency - [AE Solar AE MD-144 530W-550W (540W) vs AE Solar AE MD-144 530W-550W (535W)](https://comparepv.com/compare/ae-solar-ae-md-144-530w-550w-540w/ae-solar-ae-md-144-530w-550w-535w) - The same specification on paper - [AE Solar AE MD-144 530W-550W (540W) vs AE Solar AE MD-144 530W-550W (530W)](https://comparepv.com/compare/ae-solar-ae-md-144-530w-550w-540w/ae-solar-ae-md-144-530w-550w-530w) - 3 differences, the largest is module efficiency - [AE Solar CME-132BDS-730W vs AE Solar CME-132BDS-730](https://comparepv.com/compare/ae-solar-cme-132bds-730w/ae-solar-cme-132bds-730) - One difference: product warranty - [AE Solar CME-132BDS-730W vs AE Solar CME-132BDS-725](https://comparepv.com/compare/ae-solar-cme-132bds-730w/ae-solar-cme-132bds-725) - One difference: product warranty --- Source: https://comparepv.com/compare/ae-solar-ae-md-144-530w-550w-540w/ae-solar-cme-132bds-730w 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.
