Huasun Brand Guidelines: The 2020 Xuancheng Maker Built Around Heterojunction Cells

A young company that chose one cell technology.

Huasun is a young company. Its full name is Anhui Huasun Energy Co., Ltd., and the timeline on its own website gives its founding date as 21 July 2020, in Xuancheng, a city in China’s Anhui province where it still has its headquarters. A company press release carried by pv magazine in July 2025, written for its fifth anniversary, says Huasun was founded “amid a saturated PERC market” and chose to build the whole business around one cell technology: heterojunction, usually shortened to HJT.

That choice runs through everything the company says about itself. Its website describes Huasun as specialising in the research, development and large-scale production of n-type HJT products, and says its work covers the whole chain, from silicon ingots and wafers to cells and finished modules. In the anniversary release its chairman, Jimmy Xu, says he “believed from the start that HJT would lead the next era of solar.” Even the site’s menus are organised around the technology, with sections headed “Huasun HJT,” “HJT Cells” and “HJT Modules,” and a series of explainers titled “All About HJT.”

The first steps came quickly, by the company’s own account. Its timeline records a first module made in the laboratory in January 2021, the start of production at a 500-megawatt cell and module project in Xuancheng in March 2021, and its first HJT cell off the line a few days later. Independent reporting picks up the story in 2023. In March that year pv magazine reported that Huasun had started production at a new HJT cell factory in Xuancheng with an annual capacity of 2.4 gigawatts, making only bifacial 182 mm cells, alongside a 500-megawatt module factory it was already running in the city.

Five factory bases and a range of mountains.

Huasun has grown through a run of factories in different provinces. The company’s timeline lists the first phase of a 2.5-gigawatt cell project in Dali, in Yunnan, starting production in September 2023; a 5-gigawatt cell and module project in Hefei, the Anhui capital, in October 2023; and a 3.6-gigawatt cell project in Wuxi, in Jiangsu, in January 2024. It also names a production site in Yinchuan, in Ningxia, and a sales centre in Nanjing. The 2025 anniversary release counts five manufacturing bases in all — Xuancheng, Hefei, Wuxi, Dali and Yinchuan — and says the company had reached 20 gigawatts of production capacity. Its own timeline marks 10 gigawatts of cumulative shipments in January 2025.

Large orders came early. pv magazine reported in March 2023 that in September 2022 Huasun had signed an agreement with the eastern China unit of the state-run Power China to supply 10 gigawatts of heterojunction modules between 2022 and 2025, and that it had placed an order for 7.5 gigawatts of new heterojunction lines with the Chinese equipment supplier Maxwell, with the new capacity expected to come online in 2023.

Its modules are sold under the names of mountains. The website lists the Everest, Himalaya and Kunlun ranges, along with an Agri-PV module, a colour module and a Himalaya version called V-Ocean, listed for offshore use. The company says the Kunlun series is meant for vertical installations on farmland, along transport corridors and on building facades, and that in Europe it has worked with Next2Sun AG on nearly 100 megawatts of vertical projects, including agrivoltaics and solar fencing. The same release says Huasun has set up a 100-megawatt pilot line for tandem cells that pair HJT with perovskite.

The application pages on its site are grouped the same way, by setting rather than by product: utility plants, offshore sites, commercial and industrial roofs, homes and vertical installations, followed by case studies. A further page, headed “Module Authenticity,” is listed under service and support.

How solar makers present themselves.

Solar panel makers sell a product that looks much the same from a distance: a dark rectangle of glass divided into a grid of cells. Their visual identities work around that sameness. Company websites and brochures return again and again to a few scenes — black or blue module grids on house roofs, long rows of panels across desert or farmland at utility-scale plants, and close-ups of individual cells, where the fine lines of the metal contacts, or their absence, become the detail that sets one technology apart from another.

The factory is the second stage set. Makers show clean production lines, robotic handling and testing laboratories, and they name their cell technologies — TOPCon, heterojunction, back contact — the way other industries name materials. Product families are given short, branded names, and colour is used sparingly: a corporate blue, green or orange against white, with the dark face of the module doing most of the visual work.

Because most panels reach homes and businesses through others, makers also speak to installers. Partner programmes, installer training, distributor networks and warranty pages appear prominently on their websites, addressed to the people who specify and fit the panels.

Trade fairs are where the industry shows itself in public. Intersolar Europe at the Messe München and SNEC in Shanghai draw module makers from China, Europe, North America and elsewhere, who use large booths to launch new module families, storage systems and inverters side by side. This guide sets out what can be checked about each maker — where it began, who owns it, and what it makes — and marks clearly what rests only on the company’s own word.

A company that names itself after its cell.

Huasun presents itself first as a technology company. Its website calls it “a global leader in heterojunction (HJT) solar technology” and the “world’s largest HJT manufacturer”; both are the company’s own descriptions. It says it has supplied more than 13 gigawatts of HJT products to more than 80 countries, across Asia-Pacific, Europe, the Middle East and Africa, and Latin America, and that it has more than 2,500 employees.

Its stated vision is short: “Let solar lead as the No.1 energy.” The mission, on the same page, is “bringing superior solar clean energy into life,” and the page closes on a slogan set in capitals, “Build a zero carbon world.” The listed core values put the customer first and include technological innovation and lifelong learning. Those lines, with the HJT label repeated across products, news and explainers, do most of the work of the brand: the cell technology itself is the message.

For a design guide, Huasun shows how a young manufacturer can build a whole identity around a single technical choice, naming the technology everywhere and giving its products the names of mountains. Compare LONGi, another Chinese solar maker, and AIKO. For this guide we use a deep navy, a cool silver and a warm amber with a geometric sans, an unofficial interpretation; no product or logo is reproduced.
