According to our database: **AE Solar AE MD-120 **460 W**** has higher module efficiency (**21.35%** vs **21.11%**); **AE Solar AE ME-132BD-655** 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 MD-120 460W and AE Solar AE ME-132BD-655? **AE Solar AE MD-120 **460 W**** has a module efficiency of **21.35%**, while **AE Solar AE ME-132BD-655** is **21.11%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does AE Solar AE MD-120 460W use vs AE Solar AE ME-132BD-655? **AE Solar AE MD-120 **460 W**** uses **TOPCon** cells; **AE Solar AE ME-132BD-655** 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-120 460W and AE Solar AE ME-132BD-655? **AE Solar AE MD-120 **460 W**** has a **30 years** power warranty; **AE Solar AE ME-132BD-655** 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-120 460W and AE Solar AE ME-132BD-655 bifacial panels? **AE Solar AE ME-132BD-655** is bifacial (captures light from both faces); **AE Solar AE MD-120 **460 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-120 460W vs AE Solar ME-132BD-660](https://comparepv.com/compare/ae-solar-ae-md-120-460w/ae-solar-me-132bd-660) - 14 differences, the largest is rated power - [AE Solar AE MD-120 460W vs AE Solar AE ME-132 660W](https://comparepv.com/compare/ae-solar-ae-md-120-460w/ae-solar-ae-me-132-660w) - 11 differences, the largest is rated power - [AE Solar AE MD-120 460W vs AE Solar AE ME-132BD-660](https://comparepv.com/compare/ae-solar-ae-md-120-460w/ae-solar-ae-me-132bd-660) - 13 differences, the largest is rated power - [AE Solar AE MD-120 460W vs AE Solar AE ME-132-660](https://comparepv.com/compare/ae-solar-ae-md-120-460w/ae-solar-ae-me-132-660) - 11 differences, the largest is rated power - [AE Solar AE MD-120 460W vs AE Solar ME-132-660](https://comparepv.com/compare/ae-solar-ae-md-120-460w/ae-solar-me-132-660) - 12 differences, the largest is rated power - [AE Solar AE MD-120 460W vs AE Solar ME-132BD-655](https://comparepv.com/compare/ae-solar-ae-md-120-460w/ae-solar-me-132bd-655) - 15 differences, the largest is rated power --- Source: https://comparepv.com/compare/ae-solar-ae-md-120-460w/ae-solar-ae-me-132bd-655 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.
