According to our database: **SunEvo Solar SE6-66HBD-735** has higher module efficiency (**23.66%** vs **23.50%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of SunEvo Solar SE6-66HBD-730W and SunEvo Solar SE6-66HBD-735? **SunEvo Solar SE6-66HBD-**730 W**** has a module efficiency of **23.50%**, while **SunEvo Solar SE6-66HBD-735** is **23.66%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does SunEvo Solar SE6-66HBD-730W use vs SunEvo Solar SE6-66HBD-735? **SunEvo Solar SE6-66HBD-**730 W**** uses **HJT** cells; **SunEvo Solar SE6-66HBD-735** 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 SunEvo Solar SE6-66HBD-730W and SunEvo Solar SE6-66HBD-735? **SunEvo Solar SE6-66HBD-**730 W**** has a **30 years** power warranty; **SunEvo Solar SE6-66HBD-735** 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 SunEvo Solar SE6-66HBD-730W and SunEvo Solar SE6-66HBD-735 bifacial panels? Both **SunEvo Solar SE6-66HBD-**730 W**** and **SunEvo Solar SE6-66HBD-735** 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 - [SunEvo Solar SE6-66HBD-730W vs SunEvo Solar SE6-66HBD-750W](https://comparepv.com/compare/sunevo-solar-se6-66hbd-730w/sunevo-solar-se6-66hbd-750w) - 3 differences, the largest is module efficiency - [SunEvo Solar SE6-66HBD-730W vs SunEvo Solar SE6-66HBD-745W](https://comparepv.com/compare/sunevo-solar-se6-66hbd-730w/sunevo-solar-se6-66hbd-745w) - 3 differences, the largest is module efficiency - [SunEvo Solar SE6-66HBD-730W vs SunEvo Solar SE6-66HBD-740W](https://comparepv.com/compare/sunevo-solar-se6-66hbd-730w/sunevo-solar-se6-66hbd-740w) - 3 differences, the largest is module efficiency - [SunEvo Solar SE6-66HBD-730W vs SunEvo Solar SE6-66HBD-735W](https://comparepv.com/compare/sunevo-solar-se6-66hbd-730w/sunevo-solar-se6-66hbd-735w) - One difference: module efficiency - [SunEvo Solar SE6-66HBD-730W vs SunEvo Solar SE6-66HBD-730](https://comparepv.com/compare/sunevo-solar-se6-66hbd-730w/sunevo-solar-se6-66hbd-730) - The same specification on paper - [SunEvo Solar SE6-66HBD-730W vs SunEvo Solar SE6-66HBD-725](https://comparepv.com/compare/sunevo-solar-se6-66hbd-730w/sunevo-solar-se6-66hbd-725) - The same specification on paper --- Source: https://comparepv.com/compare/sunevo-solar-se6-66hbd-730w/sunevo-solar-se6-66hbd-735 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.
