According to our database: **Heckert Solar ZEUS 3.0+ 108 490WP** has higher module efficiency (**24.00%** vs **22.90%**); **Heckert Solar ZEUS 3.0+ 108 490WP** tolerates heat better (temp coeff **-0.260%/°C** vs **-0.280%/°C**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Heckert Solar ZEUS 2.2-710 and Heckert Solar ZEUS 3.0+ 108 490WP? **Heckert Solar ZEUS 2.2-710** has a module efficiency of **22.90%**, while **Heckert Solar ZEUS 3.0+ 108 490WP** is **24.00%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Heckert Solar ZEUS 2.2-710 use vs Heckert Solar ZEUS 3.0+ 108 490WP? **Heckert Solar ZEUS 2.2-710** uses **TOPCon** cells; **Heckert Solar ZEUS 3.0+ 108 490WP** uses **Back Contact**. 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 Heckert Solar ZEUS 2.2-710 and Heckert Solar ZEUS 3.0+ 108 490WP? **Heckert Solar ZEUS 2.2-710** has a **30 years** power warranty; **Heckert Solar ZEUS 3.0+ 108 490WP** 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 Heckert Solar ZEUS 2.2-710 and Heckert Solar ZEUS 3.0+ 108 490WP bifacial panels? Both **Heckert Solar ZEUS 2.2-710** and **Heckert Solar ZEUS 3.0+ 108 490WP** 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 - [Heckert Solar ZEUS 2.2-710 vs Heckert Solar ZEUS 2.2 715](https://comparepv.com/compare/heckert-solar-zeus-2-2-710-1/heckert-solar-zeus-2-2-715) - The same specification on paper - [Heckert Solar ZEUS 2.2-710 vs Heckert Solar ZEUS 2.2-715](https://comparepv.com/compare/heckert-solar-zeus-2-2-710-1/heckert-solar-zeus-2-2-715-1) - The same specification on paper - [Heckert Solar ZEUS 2.2-710 vs Heckert Solar ZEUS 2.2 710](https://comparepv.com/compare/heckert-solar-zeus-2-2-710-1/heckert-solar-zeus-2-2-710) - The same specification on paper - [Heckert Solar ZEUS 2.2-710 vs Heckert Solar ZEUS 2.1-640](https://comparepv.com/compare/heckert-solar-zeus-2-2-710-1/heckert-solar-zeus-2-1-640) - 10 differences, the largest is module efficiency - [Heckert Solar ZEUS 2.2-710 vs Heckert Solar ZEUS 2.1 640W](https://comparepv.com/compare/heckert-solar-zeus-2-2-710-1/heckert-solar-zeus-2-1-640w) - 9 differences, the largest is module efficiency - [Heckert Solar ZEUS 2.2-710 vs Heckert Solar ZEUS 2.1-635](https://comparepv.com/compare/heckert-solar-zeus-2-2-710-1/heckert-solar-zeus-2-1-635) - 10 differences, the largest is rated power --- Source: https://comparepv.com/compare/heckert-solar-zeus-2-2-710-1/heckert-solar-zeus-3-0-108-490wp 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.
