According to our database: **Vikram Solar PARADEA VSMDH.66.680.05** has higher module efficiency (**21.89%** vs **21.57%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Vikram Solar PARADEA VSMDH.66.680.05 and Vikram Solar PARADEA VSMDH.66.AAA.05-670? **Vikram Solar PARADEA VSMDH.66.680.05** has a module efficiency of **21.89%**, while **Vikram Solar PARADEA VSMDH.66.AAA.05-670** is **21.57%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Vikram Solar PARADEA VSMDH.66.680.05 use vs Vikram Solar PARADEA VSMDH.66.AAA.05-670? **Vikram Solar PARADEA VSMDH.66.680.05** uses **PERC** cells; **Vikram Solar PARADEA VSMDH.66.AAA.05-670** uses **PERC**. 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 Vikram Solar PARADEA VSMDH.66.680.05 and Vikram Solar PARADEA VSMDH.66.AAA.05-670? **Vikram Solar PARADEA VSMDH.66.680.05** has a **30 years** power warranty; **Vikram Solar PARADEA VSMDH.66.AAA.05-670** 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 Vikram Solar PARADEA VSMDH.66.680.05 and Vikram Solar PARADEA VSMDH.66.AAA.05-670 bifacial panels? Both **Vikram Solar PARADEA VSMDH.66.680.05** and **Vikram Solar PARADEA VSMDH.66.AAA.05-670** 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 - [Vikram Solar PARADEA VSMDH.66.680.05 vs Vikram Solar PARADEA VSMDH.66.AAA.05-680](https://comparepv.com/compare/vikram-solar-paradea-vsmdh-66-680-05/vikram-solar-paradea-vsmdh-66-aaa-05-680) - The same specification on paper - [Vikram Solar PARADEA VSMDH.66.680.05 vs Vikram Solar PARADEA VSMDH.66.AAA.05](https://comparepv.com/compare/vikram-solar-paradea-vsmdh-66-680-05/vikram-solar-paradea-vsmdh-66-aaa-05) - The same specification on paper - [Vikram Solar PARADEA VSMDH.66.680.05 vs Vikram Solar PARADEA VSMDH.66.AAA.05-675](https://comparepv.com/compare/vikram-solar-paradea-vsmdh-66-680-05/vikram-solar-paradea-vsmdh-66-aaa-05-675) - The same specification on paper - [Vikram Solar PARADEA VSMDH.66.680.05 vs Vikram Solar PARADEA VSMDH.66.675.05](https://comparepv.com/compare/vikram-solar-paradea-vsmdh-66-680-05/vikram-solar-paradea-vsmdh-66-675-05) - The same specification on paper - [Vikram Solar PARADEA VSMDH.66.680.05 vs Vikram Solar PARADEA VSMDH.66.670.05](https://comparepv.com/compare/vikram-solar-paradea-vsmdh-66-680-05/vikram-solar-paradea-vsmdh-66-670-05) - 3 differences, the largest is module efficiency - [Vikram Solar PARADEA VSMDH.66.680.05 vs Vikram Solar PARADEA VSMDH.66.AAA.05-665](https://comparepv.com/compare/vikram-solar-paradea-vsmdh-66-680-05/vikram-solar-paradea-vsmdh-66-aaa-05-665) - 3 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/vikram-solar-paradea-vsmdh-66-680-05/vikram-solar-paradea-vsmdh-66-aaa-05-670 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.
