According to our database: **Runergy HY-DH132H10-735** has higher module efficiency (**23.70%** vs **23.50%**); **Runergy HY-DH132H10-735** tolerates heat better (temp coeff **-0.260%/°C** vs **-0.290%/°C**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Runergy HY-DH132H10-735 and Trina Solar TSM-NEG21C.20-730? **Runergy HY-DH132H10-735** has a module efficiency of **23.70%**, while **Trina Solar TSM-NEG21C.20-730** is **23.50%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Runergy HY-DH132H10-735 use vs Trina Solar TSM-NEG21C.20-730? **Runergy HY-DH132H10-735** uses **HJT** cells; **Trina Solar TSM-NEG21C.20-730** 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 Runergy HY-DH132H10-735 and Trina Solar TSM-NEG21C.20-730? **Runergy HY-DH132H10-735** has a **30 years** power warranty; **Trina Solar TSM-NEG21C.20-730** 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 Runergy HY-DH132H10-735 and Trina Solar TSM-NEG21C.20-730 bifacial panels? Both **Runergy HY-DH132H10-735** and **Trina Solar TSM-NEG21C.20-730** 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 - [Runergy HY-DH132H10-735 vs Runergy HY-DH132H10-740](https://comparepv.com/compare/runergy-hy-dh132h10-735/runergy-hy-dh132h10-740) - The same specification on paper - [Runergy HY-DH132H10-735 vs Runergy HY-DH132H10-Plus-740](https://comparepv.com/compare/runergy-hy-dh132h10-735/runergy-hy-dh132h10-plus-740) - One difference: dimensions - [Runergy HY-DH132H10-735 vs Runergy HY-DH132H10-Plus-735](https://comparepv.com/compare/runergy-hy-dh132h10-735/runergy-hy-dh132h10-plus-735) - One difference: dimensions - [Runergy HY-DH132H10-735 vs Runergy HY-DH132H10-730](https://comparepv.com/compare/runergy-hy-dh132h10-735/runergy-hy-dh132h10-730) - One difference: module efficiency - [Runergy HY-DH132H10-735 vs Runergy HY-DH132N10-730](https://comparepv.com/compare/runergy-hy-dh132h10-735/runergy-hy-dh132n10-730) - 7 differences, the largest is temperature coefficient - [Runergy HY-DH132H10-735 vs Runergy HY-DH132H10-Plus-730](https://comparepv.com/compare/runergy-hy-dh132h10-735/runergy-hy-dh132h10-plus-730) - 2 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/runergy-hy-dh132h10-735/trina-solar-co-ltd-tsm-neg21c-20-730 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.
