LONGi is one of the most recognizable brands in the global photovoltaic industry. Founded in 2000 in Xi’an, China, the company has become a giant in the renewable energy market within two decades. Since 2020, it has maintained its position as a leading supplier of photovoltaic modules for Christmas and is now the largest manufacturer of silicon cells and wafers in the world, which corresponds to close to 30% of global production. In 2020, it maintains its position as the world leader in the supply of photovoltaic modules and is now the largest manufacturer of silicon cells and wafers in the world, accounting for almost 30% of global production.

About the manufacturer

The brand’s mission – “Using solar energy to build a green world” – is reflected in both innovative technologies and activities.

LONGi employs more than 60,000 people and has plants in China, Malaysia, Vietnam and the United States, as well as offices in many countries, including Europe. With a global presence, the brand’s solutions reach millions of customers around the world.

Since 2021, LONGi has also been investing in hydrogen technologies – a natural complement to solar energy and a step towards a global energy transition. Production is increasingly based on renewable energy sources, which significantly reduces the company’s carbon footprint.

Since its establishment, the company has been continuously developing monocrystalline technology to ensure the high efficiency and durability of photovoltaic modules. It has the status of a national innovation laboratory in China and cooperates with leading research centers around the world.

Solution

Intensive research and development work results in breakthrough technologies and branded products.

HPBC (Hybrid Passivated Back Contact) technology – cells with a record efficiency of more than 27%.

For years, LONGi panels have been at the forefront of the best modules in the industry, m.in in PVEL tests, where they have repeatedly won the title of Top Performer. Their technical performance, low degradation and up to 25 years of product warranty and up to 30 years of performance guarantee make them one of the most reliable choices on the market.

LONGi is a Tier 1 manufacturer, which is a testament to its financial stability and ability to support customers in the long term. Despite increasing competition and falling module prices, the company maintains its position as a global leader and constantly raises technological standards for the entire industry.

Back Contact Technology

Back Contact technology is one of Longi’s most groundbreaking achievements in the field of photovoltaics.

In this innovative design, all electrical connections have been moved to the back of the cell, so that its entire surface can absorb sunlight. The result is higher performance, greater reliability and an aesthetically pleasing, uniform appearance of the module.

The Back Contact modules are characterized by excellent performance even in difficult lighting and climatic conditions.

They ensure stable energy production for many years. By eliminating front busbars that restricted the access of light, this technology maximizes energy yield while increasing the mechanical strength and durability of the modules.

This is the solution of the future.

Efficient, aesthetically pleasing and durable, suitable for both domestic installations and large commercial projects.

Advantages of Back Contact Technology

Back Contact technology is versatile and ideal for various market segments – from residential installations, where aesthetics and efficiency are key, to large commercial systems, where reliability and long-term profitability are key. To maximize its potential, two specialized product lines have been developed: Artist, for single-family homes, and Scientist, for the commercial and industrial sectors.

Full light absorption – the lack of busbars at the front of the cell allows more energy to be obtained from the same surface.

Higher efficiency and power stability – HPBC and HPBC 2.0 cells guarantee maximum performance even in low sunlight.

Modern design – the smooth, black surface of the panel fits perfectly with the architecture of the buildings.

Increased mechanical resistance – Improved design and reverse brazing technology protect cells from micro-cracks.

Withstand extreme conditions – modules tested for wind, hail, UV and high temperature loads.

Lower Average Cost of Energy (LCOE) – Higher efficiency and lower degradation ensure long-term investment profitability.

Residential – the perfect combination of aesthetics and efficiency

The Artist series combines elegance and technology – modules in a solid black color perfectly match the architecture of modern homes.

Back Contact technology allows the panels to generate more energy even in partial shade, offering stable production and higher efficiency all year round.

The lighter design makes it easier to install on roofs with limited load-bearing capacity.

Commercial and industrial applications – maximum performance and reliability for your business

The Scientist series is designed for large installations and industrial projects where high power density and reliability are key.

HPBC 2.0 technology guarantees maximum performance in all conditions – from intense sunlight to partial shade.

Increased mechanical resistance and certified durability ensure that these panels will be ready for operation for decades.

Back Contact technology sets a new standard in photovoltaics. It combines innovation, aesthetics and excellent performance, opening a new era in the design of photovoltaic modules. It’s a trend that defines the future of clean energy – reliable, economical and sustainable.
