According to our database: **Vikram Solar HYPERSOL VSMDH.66.715.05** has higher module efficiency (**23.02%** vs **22.21%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Vikram Solar HYPERSOL VSMDH.66.690.05 and Vikram Solar HYPERSOL VSMDH.66.715.05? **Vikram Solar HYPERSOL VSMDH.66.690.05** has a module efficiency of **22.21%**, while **Vikram Solar HYPERSOL VSMDH.66.715.05** is **23.02%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Vikram Solar HYPERSOL VSMDH.66.690.05 use vs Vikram Solar HYPERSOL VSMDH.66.715.05? **Vikram Solar HYPERSOL VSMDH.66.690.05** uses **N-type** cells; **Vikram Solar HYPERSOL VSMDH.66.715.05** uses **N-type**. 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 HYPERSOL VSMDH.66.690.05 and Vikram Solar HYPERSOL VSMDH.66.715.05? **Vikram Solar HYPERSOL VSMDH.66.690.05** has a **30 years** power warranty; **Vikram Solar HYPERSOL VSMDH.66.715.05** 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 HYPERSOL VSMDH.66.690.05 and Vikram Solar HYPERSOL VSMDH.66.715.05 bifacial panels? Both **Vikram Solar HYPERSOL VSMDH.66.690.05** and **Vikram Solar HYPERSOL VSMDH.66.715.05** 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 HYPERSOL VSMDH.66.690.05 vs Vikram Solar HYPERSOL VSMDH.66.710.05](https://comparepv.com/compare/vikram-solar-hypersol-vsmdh-66-690-05/vikram-solar-hypersol-vsmdh-66-710-05) - 3 differences, the largest is module efficiency - [Vikram Solar HYPERSOL VSMDH.66.690.05 vs Vikram Solar HYPERSOL VSMDH.66.705.05](https://comparepv.com/compare/vikram-solar-hypersol-vsmdh-66-690-05/vikram-solar-hypersol-vsmdh-66-705-05) - 3 differences, the largest is module efficiency - [Vikram Solar HYPERSOL VSMDH.66.690.05 vs Vikram Solar HYPERSOL VSMDH.66.700.05](https://comparepv.com/compare/vikram-solar-hypersol-vsmdh-66-690-05/vikram-solar-hypersol-vsmdh-66-700-05) - 3 differences, the largest is module efficiency - [Vikram Solar HYPERSOL VSMDH.66.690.05 vs Vikram Solar HYPERSOL VSMDH.66.695.05](https://comparepv.com/compare/vikram-solar-hypersol-vsmdh-66-690-05/vikram-solar-hypersol-vsmdh-66-695-05) - The same specification on paper - [Vikram Solar HYPERSOL VSMDH.66.690.05 vs Vikram Solar SURYAVA VSMDH.66.735.05](https://comparepv.com/compare/vikram-solar-hypersol-vsmdh-66-690-05/vikram-solar-suryava-vsmdh-66-735-05) - 9 differences, the largest is module efficiency - [Vikram Solar HYPERSOL VSMDH.66.690.05 vs Vikram Solar SURYAVA VSMDH.66.730.05](https://comparepv.com/compare/vikram-solar-hypersol-vsmdh-66-690-05/vikram-solar-suryava-vsmdh-66-730-05) - 10 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/vikram-solar-hypersol-vsmdh-66-690-05/vikram-solar-hypersol-vsmdh-66-715-05 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.
