According to our database: **Vikram Solar HYPERSOL VSMDH.78.625.05** has higher module efficiency (**22.44%** vs **22.08%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Vikram Solar HYPERSOL VSMDH.78.615.05 and Vikram Solar HYPERSOL VSMDH.78.625.05? **Vikram Solar HYPERSOL VSMDH.78.615.05** has a module efficiency of **22.08%**, while **Vikram Solar HYPERSOL VSMDH.78.625.05** is **22.44%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Vikram Solar HYPERSOL VSMDH.78.615.05 use vs Vikram Solar HYPERSOL VSMDH.78.625.05? **Vikram Solar HYPERSOL VSMDH.78.615.05** uses **TOPCon** cells; **Vikram Solar HYPERSOL VSMDH.78.625.05** 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 Vikram Solar HYPERSOL VSMDH.78.615.05 and Vikram Solar HYPERSOL VSMDH.78.625.05? **Vikram Solar HYPERSOL VSMDH.78.615.05** has a **30 years** power warranty; **Vikram Solar HYPERSOL VSMDH.78.625.05** 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.78.615.05 and Vikram Solar HYPERSOL VSMDH.78.625.05 bifacial panels? Both **Vikram Solar HYPERSOL VSMDH.78.615.05** and **Vikram Solar HYPERSOL VSMDH.78.625.05** 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.78.615.05 vs Vikram Solar HYPERSOL VSMDH.78.630.05](https://comparepv.com/compare/vikram-solar-hypersol-vsmdh-78-615-05/vikram-solar-hypersol-vsmdh-78-630-05) - 3 differences, the largest is module efficiency - [Vikram Solar HYPERSOL VSMDH.78.615.05 vs Vikram Solar HYPERSOL VSMDH.78.620.05](https://comparepv.com/compare/vikram-solar-hypersol-vsmdh-78-615-05/vikram-solar-hypersol-vsmdh-78-620-05) - The same specification on paper - [Vikram Solar HYPERSOL VSMDH.78.615.05 vs Vikram Solar HYPERSOL VSMDH.78.610.05](https://comparepv.com/compare/vikram-solar-hypersol-vsmdh-78-615-05/vikram-solar-hypersol-vsmdh-78-610-05) - The same specification on paper - [Vikram Solar HYPERSOL VSMDH.78.615.05 vs Vikram Solar HYPERSOL VSMDH.78.605.05](https://comparepv.com/compare/vikram-solar-hypersol-vsmdh-78-615-05/vikram-solar-hypersol-vsmdh-78-605-05) - 3 differences, the largest is module efficiency - [Vikram Solar HYPERSOL VSMDH.78.615.05 vs Vikram Solar SURYAVA VSMDH.66.735.05](https://comparepv.com/compare/vikram-solar-hypersol-vsmdh-78-615-05/vikram-solar-suryava-vsmdh-66-735-05) - 14 differences, the largest is module efficiency - [Vikram Solar HYPERSOL VSMDH.78.615.05 vs Vikram Solar SURYAVA VSMDH.66.730.05](https://comparepv.com/compare/vikram-solar-hypersol-vsmdh-78-615-05/vikram-solar-suryava-vsmdh-66-730-05) - 14 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/vikram-solar-hypersol-vsmdh-78-615-05/vikram-solar-hypersol-vsmdh-78-625-05 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.
