According to our database: **Trina Solar TSM-NE21 **700 W**** has higher module efficiency (**22.50%** vs **22.40%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Trina Solar TSM-NE21 695W and Trina Solar TSM-NE21 700W? **Trina Solar TSM-NE21 **695 W**** has a module efficiency of **22.40%**, while **Trina Solar TSM-NE21 **700 W**** is **22.50%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Trina Solar TSM-NE21 695W use vs Trina Solar TSM-NE21 700W? **Trina Solar TSM-NE21 **695 W**** uses **TOPCon** cells; **Trina Solar TSM-NE21 **700 W**** 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 Trina Solar TSM-NE21 695W and Trina Solar TSM-NE21 700W? **Trina Solar TSM-NE21 **695 W**** has a **25 years** power warranty; **Trina Solar TSM-NE21 **700 W**** has a **25 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. ## Related comparisons - [Trina Solar TSM-NE21 695W vs Trina Solar TSM-NE21 725W](https://comparepv.com/compare/trina-solar-co-ltd-tsm-ne21-695w/trina-solar-co-ltd-tsm-ne21-725w) - 5 differences, the largest is module efficiency - [Trina Solar TSM-NE21 695W vs Trina Solar TSM-NE21 720W](https://comparepv.com/compare/trina-solar-co-ltd-tsm-ne21-695w/trina-solar-co-ltd-tsm-ne21-720w) - 5 differences, the largest is module efficiency - [Trina Solar TSM-NE21 695W vs Trina Solar TSM-NE21 715W](https://comparepv.com/compare/trina-solar-co-ltd-tsm-ne21-695w/trina-solar-co-ltd-tsm-ne21-715w) - 3 differences, the largest is module efficiency - [Trina Solar TSM-NE21 695W vs Trina Solar TSM-NE21 710W](https://comparepv.com/compare/trina-solar-co-ltd-tsm-ne21-695w/trina-solar-co-ltd-tsm-ne21-710w) - 3 differences, the largest is module efficiency - [Trina Solar TSM-NE21 695W vs Trina Solar TSM-NE21 705W](https://comparepv.com/compare/trina-solar-co-ltd-tsm-ne21-695w/trina-solar-co-ltd-tsm-ne21-705w) - 3 differences, the largest is module efficiency - [Trina Solar TSM-NE21 695W vs Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/compare/trina-solar-co-ltd-tsm-ne21-695w/trina-solar-tsm-neg21c-20q-760) - 13 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/trina-solar-co-ltd-tsm-ne21-695w/trina-solar-co-ltd-tsm-ne21-700w 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.
