According to our database: **AE Solar MD-144BS-**550 W**** has higher module efficiency (**21.31%** vs **21.27%**); **AE Solar AE ME-132 **660 W**** 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 AE ME-132 660W and AE Solar MD-144BS-550W? **AE Solar AE ME-132 **660 W**** has a module efficiency of **21.27%**, while **AE Solar MD-144BS-**550 W**** is **21.31%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does AE Solar AE ME-132 660W use vs AE Solar MD-144BS-550W? **AE Solar AE ME-132 **660 W**** uses **PERC** cells; **AE Solar MD-144BS-**550 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 ME-132 660W and AE Solar MD-144BS-550W? **AE Solar AE ME-132 **660 W**** has a **30 years** power warranty; **AE Solar MD-144BS-**550 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 ME-132 660W and AE Solar MD-144BS-550W bifacial panels? **AE Solar MD-144BS-**550 W**** is bifacial (captures light from both faces); **AE Solar AE ME-132 **660 W**** is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath. ## Related comparisons - [AE Solar AE ME-132 660W vs AE Solar AE ME-132 655W](https://comparepv.com/compare/ae-solar-ae-me-132-660w/ae-solar-ae-me-132-655w) - The same specification on paper - [AE Solar AE ME-132 660W vs AE Solar AE ME-132 650W](https://comparepv.com/compare/ae-solar-ae-me-132-660w/ae-solar-ae-me-132-650w) - 3 differences, the largest is module efficiency - [AE Solar AE ME-132 660W vs AE Solar AE ME-132 645W](https://comparepv.com/compare/ae-solar-ae-me-132-660w/ae-solar-ae-me-132-645w) - 3 differences, the largest is module efficiency - [AE Solar AE ME-132 660W vs AE Solar AE ME-132 640W](https://comparepv.com/compare/ae-solar-ae-me-132-660w/ae-solar-ae-me-132-640w) - 3 differences, the largest is module efficiency - [AE Solar MD-144BS-550W vs AE Solar ME-132BD-660](https://comparepv.com/compare/ae-solar-md-144bs-550w/ae-solar-me-132bd-660) - 11 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 --- Source: https://comparepv.com/compare/ae-solar-ae-me-132-660w/ae-solar-md-144bs-550w 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.
