According to our database: **AE Solar AE MD-144 **530 W**-**550 W** (**540 W**)** has higher module efficiency (**20.92%** vs **20.73%**). 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 (535W) and AE Solar AE MD-144 530W-550W (540W)? **AE Solar AE MD-144 **530 W**-**550 W** (**535 W**)** has a module efficiency of **20.73%**, while **AE Solar AE MD-144 **530 W**-**550 W** (**540 W**)** is **20.92%**. 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 (535W) use vs AE Solar AE MD-144 530W-550W (540W)? **AE Solar AE MD-144 **530 W**-**550 W** (**535 W**)** uses **PERC** cells; **AE Solar AE MD-144 **530 W**-**550 W** (**540 W**)** 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 AE Solar AE MD-144 530W-550W (535W) and AE Solar AE MD-144 530W-550W (540W)? **AE Solar AE MD-144 **530 W**-**550 W** (**535 W**)** has a **30 years** power warranty; **AE Solar AE MD-144 **530 W**-**550 W** (**540 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. ## Related comparisons - [AE Solar AE MD-144 530W-550W (535W) vs AE Solar AE MD-144 530W-550W (550W)](https://comparepv.com/compare/ae-solar-ae-md-144-530w-550w-535w/ae-solar-ae-md-144-530w-550w-550w) - 4 differences, the largest is module efficiency - [AE Solar AE MD-144 530W-550W (535W) vs AE Solar AE MD-144 530W-550W (545W)](https://comparepv.com/compare/ae-solar-ae-md-144-530w-550w-535w/ae-solar-ae-md-144-530w-550w-545w) - 3 differences, the largest is module efficiency - [AE Solar AE MD-144 530W-550W (535W) vs AE Solar AE MD-144 530W-550W (530W)](https://comparepv.com/compare/ae-solar-ae-md-144-530w-550w-535w/ae-solar-ae-md-144-530w-550w-530w) - One difference: module efficiency - [AE Solar AE MD-144 530W-550W (535W) vs AE Solar CME-132BDS-730](https://comparepv.com/compare/ae-solar-ae-md-144-530w-550w-535w/ae-solar-cme-132bds-730) - 13 differences, the largest is module efficiency - [AE Solar AE MD-144 530W-550W (535W) vs AE Solar CME-132BDS-730W](https://comparepv.com/compare/ae-solar-ae-md-144-530w-550w-535w/ae-solar-cme-132bds-730w) - 12 differences, the largest is module efficiency - [AE Solar AE MD-144 530W-550W (535W) vs AE Solar CME-132BDS-725](https://comparepv.com/compare/ae-solar-ae-md-144-530w-550w-535w/ae-solar-cme-132bds-725) - 13 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/ae-solar-ae-md-144-530w-550w-535w/ae-solar-ae-md-144-530w-550w-540w 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.
