According to our database: **LEDVANCE M700N66UB-SF-F7** has higher module efficiency (**22.53%** vs **22.37%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of LEDVANCE M685~705N66UB-SF-F7-695 and LEDVANCE M700N66UB-SF-F7? **LEDVANCE M685~705N66UB-SF-F7-695** has a module efficiency of **22.37%**, while **LEDVANCE M700N66UB-SF-F7** is **22.53%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does LEDVANCE M685~705N66UB-SF-F7-695 use vs LEDVANCE M700N66UB-SF-F7? **LEDVANCE M685~705N66UB-SF-F7-695** uses **TOPCon** cells; **LEDVANCE M700N66UB-SF-F7** 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 LEDVANCE M685~705N66UB-SF-F7-695 and LEDVANCE M700N66UB-SF-F7? **LEDVANCE M685~705N66UB-SF-F7-695** has a **30 years** power warranty; **LEDVANCE M700N66UB-SF-F7** 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 LEDVANCE M685~705N66UB-SF-F7-695 and LEDVANCE M700N66UB-SF-F7 bifacial panels? Both **LEDVANCE M685~705N66UB-SF-F7-695** and **LEDVANCE M700N66UB-SF-F7** 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 - [LEDVANCE M685~705N66UB-SF-F7-695 vs LEDVANCE M685~705N66UB-SF-F7-705](https://comparepv.com/compare/ledvance-m685-705n66ub-sf-f7-695/ledvance-m685-705n66ub-sf-f7-705) - 3 differences, the largest is module efficiency - [LEDVANCE M685~705N66UB-SF-F7-695 vs LEDVANCE M705N66UB-SF-F7](https://comparepv.com/compare/ledvance-m685-705n66ub-sf-f7-695/ledvance-m705n66ub-sf-f7) - 3 differences, the largest is module efficiency - [LEDVANCE M685~705N66UB-SF-F7-695 vs LEDVANCE M685~705N66UB-SF-F7-700](https://comparepv.com/compare/ledvance-m685-705n66ub-sf-f7-695/ledvance-m685-705n66ub-sf-f7-700) - The same specification on paper - [LEDVANCE M685~705N66UB-SF-F7-695 vs LEDVANCE M695N66UB-SF-F7](https://comparepv.com/compare/ledvance-m685-705n66ub-sf-f7-695/ledvance-m695n66ub-sf-f7) - The same specification on paper - [LEDVANCE M685~705N66UB-SF-F7-695 vs LEDVANCE M685~705N66UB-SF-F7-690](https://comparepv.com/compare/ledvance-m685-705n66ub-sf-f7-695/ledvance-m685-705n66ub-sf-f7-690) - The same specification on paper - [LEDVANCE M685~705N66UB-SF-F7-695 vs LEDVANCE M690N66UB-SF-F7](https://comparepv.com/compare/ledvance-m685-705n66ub-sf-f7-695/ledvance-m690n66ub-sf-f7) - The same specification on paper --- Source: https://comparepv.com/compare/ledvance-m685-705n66ub-sf-f7-695/ledvance-m700n66ub-sf-f7 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.
