According to our database: **AE Solar MD-144BS-**550 W**** has higher module efficiency (**21.31%** vs **21.27%**); **AE Solar ME-132BD-660** tolerates heat better (temp coeff **-0.340%/°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 MD-144BS-550W and AE Solar ME-132BD-660? **AE Solar MD-144BS-**550 W**** has a module efficiency of **21.31%**, while **AE Solar ME-132BD-660** is **21.27%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does AE Solar MD-144BS-550W use vs AE Solar ME-132BD-660? **AE Solar MD-144BS-**550 W**** uses **PERC** cells; **AE Solar ME-132BD-660** 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 MD-144BS-550W and AE Solar ME-132BD-660? **AE Solar MD-144BS-**550 W**** has a **30 years** power warranty; **AE Solar ME-132BD-660** 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 MD-144BS-550W and AE Solar ME-132BD-660 bifacial panels? Both **AE Solar MD-144BS-**550 W**** and **AE Solar ME-132BD-660** 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 MD-144BS-550W vs AE Solar AE ME-132 660W](https://comparepv.com/compare/ae-solar-md-144bs-550w/ae-solar-ae-me-132-660w) - 12 differences, the largest is rated power - [AE Solar MD-144BS-550W vs AE Solar AE ME-132BD-660](https://comparepv.com/compare/ae-solar-md-144bs-550w/ae-solar-ae-me-132bd-660) - 12 differences, the largest is rated power - [AE Solar MD-144BS-550W vs AE Solar AE ME-132-660](https://comparepv.com/compare/ae-solar-md-144bs-550w/ae-solar-ae-me-132-660) - 12 differences, the largest is rated power - [AE Solar MD-144BS-550W vs AE Solar ME-132-660](https://comparepv.com/compare/ae-solar-md-144bs-550w/ae-solar-me-132-660) - 11 differences, the largest is rated power - [AE Solar MD-144BS-550W vs AE Solar ME-132BD-655](https://comparepv.com/compare/ae-solar-md-144bs-550w/ae-solar-me-132bd-655) - 12 differences, the largest is rated power - [AE Solar MD-144BS-550W vs AE Solar AE ME-132 655W](https://comparepv.com/compare/ae-solar-md-144bs-550w/ae-solar-ae-me-132-655w) - 13 differences, the largest is rated power --- Source: https://comparepv.com/compare/ae-solar-md-144bs-550w/ae-solar-me-132bd-660 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.
