According to our database: **TN Solar SE6-66HBD-700** 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 TN Solar SE6-66HBD-695 and TN Solar SE6-66HBD-700? **TN Solar SE6-66HBD-695** has a module efficiency of **22.37%**, while **TN Solar SE6-66HBD-700** is **22.53%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does TN Solar SE6-66HBD-695 use vs TN Solar SE6-66HBD-700? **TN Solar SE6-66HBD-695** uses **HJT** cells; **TN Solar SE6-66HBD-700** uses **HJT**. 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 TN Solar SE6-66HBD-695 and TN Solar SE6-66HBD-700? **TN Solar SE6-66HBD-695** has a **30 years** power warranty; **TN Solar SE6-66HBD-700** 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 TN Solar SE6-66HBD-695 and TN Solar SE6-66HBD-700 bifacial panels? Both **TN Solar SE6-66HBD-695** and **TN Solar SE6-66HBD-700** 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 - [TN Solar SE6-66HBD-695 vs TN Solar SE6-66HBD-715](https://comparepv.com/compare/tn-solar-se6-66hbd-695/tn-solar-se6-66hbd-715) - 3 differences, the largest is module efficiency - [TN Solar SE6-66HBD-695 vs TN Solar SE6-66HBD-710](https://comparepv.com/compare/tn-solar-se6-66hbd-695/tn-solar-se6-66hbd-710) - 3 differences, the largest is module efficiency - [TN Solar SE6-66HBD-695 vs TN Solar SE6-66HBD-705](https://comparepv.com/compare/tn-solar-se6-66hbd-695/tn-solar-se6-66hbd-705) - 3 differences, the largest is module efficiency - [TN Solar SE6-66HBD-695 vs TN Solar TN5-54H-390](https://comparepv.com/compare/tn-solar-se6-66hbd-695/tn-solar-tn5-54h-390) - 14 differences, the largest is module efficiency - [TN Solar SE6-66HBD-695 vs TN Solar TN5-54H-385](https://comparepv.com/compare/tn-solar-se6-66hbd-695/tn-solar-tn5-54h-385) - 14 differences, the largest is module efficiency - [TN Solar SE6-66HBD-695 vs TN Solar TN5-54H-380](https://comparepv.com/compare/tn-solar-se6-66hbd-695/tn-solar-tn5-54h-380) - 14 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/tn-solar-se6-66hbd-695/tn-solar-se6-66hbd-700 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.
