According to our database: **Axitec AC-700TGB/132TS** has higher module efficiency (**22.53%** vs **22.27%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Axitec AC-445TGBL/108BB and Axitec AC-700TGB/132TS? **Axitec AC-445TGBL/108BB** has a module efficiency of **22.27%**, while **Axitec AC-700TGB/132TS** is **22.53%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Axitec AC-445TGBL/108BB use vs Axitec AC-700TGB/132TS? **Axitec AC-445TGBL/108BB** uses **TOPCon** cells; **Axitec AC-700TGB/132TS** 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 Axitec AC-445TGBL/108BB and Axitec AC-700TGB/132TS? **Axitec AC-445TGBL/108BB** has a **30 years** power warranty; **Axitec AC-700TGB/132TS** 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 Axitec AC-445TGBL/108BB and Axitec AC-700TGB/132TS bifacial panels? Both **Axitec AC-445TGBL/108BB** and **Axitec AC-700TGB/132TS** 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 - [Axitec AC-445TGBL/108BB vs Axitec AC-460TGBL/108WB](https://comparepv.com/compare/axitec-ac-445tgbl-108bb/axitec-ac-460tgbl-108wb) - 3 differences, the largest is module efficiency - [Axitec AC-445TGBL/108BB vs Axitec AC-455TGBL/108BB](https://comparepv.com/compare/axitec-ac-445tgbl-108bb/axitec-ac-455tgbl-108bb) - 3 differences, the largest is module efficiency - [Axitec AC-445TGBL/108BB vs Axitec AC-450TGBL/108BB](https://comparepv.com/compare/axitec-ac-445tgbl-108bb/axitec-ac-450tgbl-108bb) - One difference: module efficiency - [Axitec AC-445TGBL/108BB vs Axitec AC-440TGBL/108BB](https://comparepv.com/compare/axitec-ac-445tgbl-108bb/axitec-ac-440tgbl-108bb) - One difference: module efficiency - [Axitec AC-700TGB/132TS vs Axitec AC-710TGB/132TS](https://comparepv.com/compare/axitec-ac-700tgb-132ts/axitec-ac-710tgb-132ts) - 3 differences, the largest is module efficiency - [Axitec AC-700TGB/132TS vs Axitec AC-705TGB/132TS](https://comparepv.com/compare/axitec-ac-700tgb-132ts/axitec-ac-705tgb-132ts) - The same specification on paper --- Source: https://comparepv.com/compare/axitec-ac-445tgbl-108bb/axitec-ac-700tgb-132ts 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.
