According to our database: **Solarever SE-182\*105-620M-132-BD** has higher module efficiency (**22.95%** vs **22.80%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Solarever SE-182\*105-615M-132-BD and Solarever SE-182\*105-620M-132-BD? **Solarever SE-182\*105-615M-132-BD** has a module efficiency of **22.80%**, while **Solarever SE-182\*105-620M-132-BD** is **22.95%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Solarever SE-182\*105-615M-132-BD use vs Solarever SE-182\*105-620M-132-BD? **Solarever SE-182\*105-615M-132-BD** uses **TOPCon** cells; **Solarever SE-182\*105-620M-132-BD** 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 Solarever SE-182\*105-615M-132-BD and Solarever SE-182\*105-620M-132-BD? **Solarever SE-182\*105-615M-132-BD** has a **30 years** power warranty; **Solarever SE-182\*105-620M-132-BD** 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 Solarever SE-182\*105-615M-132-BD and Solarever SE-182\*105-620M-132-BD bifacial panels? Both **Solarever SE-182\*105-615M-132-BD** and **Solarever SE-182\*105-620M-132-BD** 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 - [Solarever SE-182\*105-615M-132-BD vs Solarever SE-182\*105-630M-132-BD](https://comparepv.com/compare/solarever-se-182-105-615m-132-bd/solarever-se-182-105-630m-132-bd) - 3 differences, the largest is module efficiency - [Solarever SE-182\*105-615M-132-BD vs Solarever SE-182\*105-625M-132-BD](https://comparepv.com/compare/solarever-se-182-105-615m-132-bd/solarever-se-182-105-625m-132-bd) - 3 differences, the largest is module efficiency - [Solarever SE-182\*105-615M-132-BD vs Solarever SE-182\*105-610M-132-BD](https://comparepv.com/compare/solarever-se-182-105-615m-132-bd/solarever-se-182-105-610m-132-bd) - One difference: module efficiency - [Solarever SE-182\*105-615M-132-BD vs Solarever SE-182\*105-605M-132-BD](https://comparepv.com/compare/solarever-se-182-105-615m-132-bd/solarever-se-182-105-605m-132-bd) - 3 differences, the largest is module efficiency - [Solarever SE-182\*105-615M-132-BD vs Solarever SE-182\*105-600M-132-BD](https://comparepv.com/compare/solarever-se-182-105-615m-132-bd/solarever-se-182-105-600m-132-bd) - 3 differences, the largest is module efficiency - [Solarever SE-182\*105-615M-132-BD vs Solarever SE-182\*105-470M-96-BD](https://comparepv.com/compare/solarever-se-182-105-615m-132-bd/solarever-se-182-105-470m-96-bd) - 11 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/solarever-se-182-105-615m-132-bd/solarever-se-182-105-620m-132-bd 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.
