Q Cells Solar Panels: The Most Comprehensive Online Review

Q Cells (often called QCells) is a pioneer in the solar industry. The history of this company began in the 1990s when no one took renewable energy seriously. A group of engineers risked it all while deciding to tie their lives to the solar industry – and the risk paid off.

Over the years, Q Cells has been featured in countless solar panel shortlists and ratings, including Forbes, and they are still one of the most prominent companies out there, constantly releasing solar panels and batteries for household and commercial usage.

We’ve compiled a comprehensive educational guide on Q Cells to help you learn more about the company and, as a result, choose the right solar panel at a reasonable price.

Without any further ado, let’s dig into it.

Q Cells History

The history of Q CELLS dates back to 1999, the peak of non-renewable power generation, where most people used oil and soil to generate energy.

However, a group of German-based solar industry pioneers wasn’t afraid of that, deciding to develop solar cells for business and domestic use. After two decades, solar energy generates 4.5% of the total electric energy, being the third largest renewable electricity technology after source hydropower and wind.

The company’s first polycrystalline solar cell production line started in 2001. In 2005, Q Cells went public on the Frankfurt Stock Exchange, displaying strength and plans to expand globally.

During the late 00s, they introduced new solar cell technologies, including Q.ANTUM and Q.PEAK, solidifying their position as the solar industry leader.

The dawn of renewable energy in the early 2010s raised competition dramatically, leading to Q Cells’ bankruptcy in 2011 and its subsequent acquisition by Hanwha Group in August 2012. The company was renamed Hanwha Q Cells, but the acquisition turned out a success. The engineers got money to continue creating bold innovations without fearing bankruptcy.

Under Hanwha’s leadership, Q Cells expanded its global manufacturing footprint to four continents, introducing groundbreaking solar cell technologies that set industry benchmarks for efficiency and performance.

Today, Q Cells is a global solar powerhouse with facilities in the USA, Europe, Asia, and Oceania. Their panels are used in residential, commercial, and utility-scale projects worldwide.

In 2011, Q.Antum technology set the world efficiency record for polycrystalline solar cells at 19.5%, which looks solid even today, when Q.Antum efficiency is up to 21,6%.

The high efficiency of solar cells makes Q Cell solar panels one of the most favorable options on the market. The reflective layer in Q.ANTUM cells traps and utilizes light that would otherwise escape the cell, minimizing energy losses and maximizing power output. Multi-busbar technology reduces resistance and improves electron capturing.

Instead of a single wide busbar, they provide multiple narrower options to reduce the distance between connection points. This approach lowers resistance and alleviates congestion, allowing electrons to move more freely within the cell and increase the power output by 2% compared to traditional panels.

Half-cell technology divides traditional cells into multiple parts. It reduces the distance between the connection points, which in turn reduces the current flowing through the cell. That way, a Q Cell achieves a 3% increase in power output compared to traditional full-cell designs.

Q.ANTUM technology enhances the cells’ performance in low-light terms, like sunset and cloudy days. These cells can maintain high efficiency during hot and cold temperatures, down to -15°C (5°F). You can use them in southern states like California or Florida and in northern states like Washington or Illinois.

Q Cells panels achieve efficient space usage, providing the same amount of electricity through fewer modules.
