According to our database: **Vikram Solar PARADEA VSMDH.72.AAA.05-555** has higher module efficiency (**21.48%** vs **21.29%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Vikram Solar PARADEA VSMDH.72.AAA.05-550 and Vikram Solar PARADEA VSMDH.72.AAA.05-555? **Vikram Solar PARADEA VSMDH.72.AAA.05-550** has a module efficiency of **21.29%**, while **Vikram Solar PARADEA VSMDH.72.AAA.05-555** is **21.48%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Vikram Solar PARADEA VSMDH.72.AAA.05-550 use vs Vikram Solar PARADEA VSMDH.72.AAA.05-555? **Vikram Solar PARADEA VSMDH.72.AAA.05-550** uses **PERC** cells; **Vikram Solar PARADEA VSMDH.72.AAA.05-555** 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.72.AAA.05-550 and Vikram Solar PARADEA VSMDH.72.AAA.05-555? **Vikram Solar PARADEA VSMDH.72.AAA.05-550** has a **30 years** power warranty; **Vikram Solar PARADEA VSMDH.72.AAA.05-555** 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.72.AAA.05-550 and Vikram Solar PARADEA VSMDH.72.AAA.05-555 bifacial panels? Both **Vikram Solar PARADEA VSMDH.72.AAA.05-550** and **Vikram Solar PARADEA VSMDH.72.AAA.05-555** 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.72.AAA.05-550 vs Vikram Solar PARADEA VSMDH.72.AAA.05-565](https://comparepv.com/compare/vikram-solar-paradea-vsmdh-72-aaa-05-550/vikram-solar-paradea-vsmdh-72-aaa-05-565) - 3 differences, the largest is module efficiency - [Vikram Solar PARADEA VSMDH.72.AAA.05-550 vs Vikram Solar PARADEA VSMDH.72.AAA.05-560](https://comparepv.com/compare/vikram-solar-paradea-vsmdh-72-aaa-05-550/vikram-solar-paradea-vsmdh-72-aaa-05-560) - 3 differences, the largest is module efficiency - [Vikram Solar PARADEA VSMDH.72.AAA.05-550 vs Vikram Solar PARADEA VSMDH.72.AAA.05-545](https://comparepv.com/compare/vikram-solar-paradea-vsmdh-72-aaa-05-550/vikram-solar-paradea-vsmdh-72-aaa-05-545) - The same specification on paper - [Vikram Solar PARADEA VSMDH.72.AAA.05-550 vs Vikram Solar PARADEA VSMDH.72.AAA.05-540](https://comparepv.com/compare/vikram-solar-paradea-vsmdh-72-aaa-05-550/vikram-solar-paradea-vsmdh-72-aaa-05-540) - 3 differences, the largest is module efficiency - [Vikram Solar PARADEA VSMDH.72.AAA.05-550 vs Vikram Solar SURYAVA VSMDH.66.735.05](https://comparepv.com/compare/vikram-solar-paradea-vsmdh-72-aaa-05-550/vikram-solar-suryava-vsmdh-66-735-05) - 15 differences, the largest is module efficiency - [Vikram Solar PARADEA VSMDH.72.AAA.05-550 vs Vikram Solar SURYAVA VSMDH.66.730.05](https://comparepv.com/compare/vikram-solar-paradea-vsmdh-72-aaa-05-550/vikram-solar-suryava-vsmdh-66-730-05) - 15 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/vikram-solar-paradea-vsmdh-72-aaa-05-550/vikram-solar-paradea-vsmdh-72-aaa-05-555 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.
