Top 10: Solar Panel Manufacturers

Nowadays, the companies that make solar panels are far more than simple manufacturers.

As the custodians of such a vital and in-demand product, these firms have to straddle everything from climate policy to geopolitics to nuts-and-bolts engineering.

It is no exaggeration to say that their success in these matters shapes how quickly and cost effectively entire countries are able to decarbonise.

Their factories are the engine rooms of national energy security plans, feeding the urgent appetite for clean, stable energy.

In this Top 10, we take a look at those manufacturers that are shaping the future of energy.

10. REC Group

Founded: 1996​
HQ: Lysaker, Norway
CEO: Jan Ekko Bicker

REC Group has carved out a distinctive position in the premium rooftop segment, particularly across Europe, by focusing on reliability, low degradation and tight quality control. 

With its manufacturing anchored in Asia but its corporate roots in Scandinavia, REC has a truly global footprint.

Its modules are known for low warranty claim rates and strong performance in constrained rooftop spaces, making the firm a favourite among installers seeking higher‑end offerings for residential and commercial customers.​

9. Risen Energy

Founded: 1986
HQ: Ningbo City, China
CEO: Xuegang Wu

Since 1986, Risen Energy has transformed from a simple component supplier into a vertically minded solar technology provider, with strengths in both utility‑scale projects and distributed generation. 

In recent years, its focus has been on improving efficiency and lifetime yields, while its investments in battery storage technologies have made the firm a true one-stop shop. 

With key manufacturing hubs in China and Malaysia, Risen produces an eye-watering 48GW of solar capacity every year, serving customers around the world.

8. Qcells

Founded: 1999
HQ: Seoul, South Korea
CEO: ​​​​​​​Park Seung-deok

Qcells has been on quite a journey since its founding in 1999. What began as a small-scale facility in Saxony, Germany, has become a vast operation after the firm was acquired by Korean conglomerate Hanwha in 2012.

Rather than focusing solely on panel efficiency, the company is increasingly focused on offering complete solutions, encompassing everything from production, to storage, to optimisation.

Its growing US and European manufacturing footprints also make Qcells a partner of choice for buyers around the world.

7. First Solar

Founded: 1999
HQ: Tempe, Arizona, USA
CEO: Mark Widmar

First Solar’s proprietary thin‑film CdTe technology can excel in high temperatures and challenging desert environments, helping the US firm to stand out from much of the crowd. 

The company has become a strategic pillar of US industrial policy, regularly announcing new domestic factories that tap into incentives designed to localise solar manufacturing. 

First Solar is often the default choice for utility‑scale developers looking for reliable output and excellent ESG credentials in markets around the world.

6. Trina Solar

Founded: 1997
HQ: Changzhou, China​​​​​​​
CEO: Jao Gifan

Trina has grown from an PV pioneer into one of the world’s most recognisable module brands, especially for grid-level generation. 

Its Vertex modules are routinely ranked among the most powerful available. Meanwhile, the firm’s holistic systems make it a one-stop shop from engineering to commissioning. 

Trina’s impressive global track record and bankability have helped the company to secure a steady pipeline of large projects in regions including Latin America, Europe and Asia, even as competition intensifies.

5. JA Solar

Founded: 1997
HQ: Changzhou, China​​​​​​​
CEO: Jao Gifan

In just over 20 years, JA Solar has become one of the biggest movers of megawatts anywhere in the world. 

The company’s reputation rests on consistently bankable, high‑efficiency modules that appeal to developers and buyers looking for cost-effective yet high-quality solar panels. 

JA is a popular choice for installations of any scale, from vast arrays to small rooftop fittings. The length of the firm’s warranties is particularly notable, with 30-year guarantees for the performance of its products.

4. Canadian Solar

Founded: 2001
HQ: Kitchener, Ontario, Canada
CEO: Shawn Qu

Despite its name, Canadian Solar’s manufacturing operations have always had a strong base in China. 

Founded in 2001 by Chinese-Canadian businessman Shawn Qu in Ontario, the firm has expanded globally in the quarter century since, setting up hubs in Thailand, Vietnam and Texas. 

Its modules are used in installations of all scales, but the real differentiator is the firm’s growing pipeline of solar‑plus‑storage projects, positioning Canadian Solar as both a technology supplier and long‑term leader for the energy transition.

3. LONGi Green Energy

Founded: 2001
HQ: Kitchener, Ontario, Canada
CEO: Shawn Qu

It would be an understatement to say LONGi has helped to raise the bar for the modern solar industry many times over. 

The Chinese firm’s skill in producing monocrystalline technology has elevated the efficiency of modules across the board while driving down the cost of solar worldwide. 

LONGi’s aim is to become the world’s most valuable solar company and, thanks to its major R&D investments, it may achieve that target in the near future.

2. Astronergy

Founded: 2006
HQ: Haining, China​​​​​​​
CEO: Chuan Lu

In its two-decade history, Astronergy has blossomed from a private sector PV manufacturer into a top-tier, high‑efficiency module specialist with global recognition. 

The company’s ASTRO series is at home everywhere, from residential rooftops to large-scale plants and solar farms, combining high power density with competitive prices. The firm has a portfolio of state-of-the-art manufacturing bases across multiple continents, as well as branch offices in markets like Germany, the US and Brazil. 

As such, Astronergy is able to navigate shifts in regional rules and regulations with a worldly ease. Its strategic “3D” playbook of differentiation, downstream expansion and diversification, established by the firm’s leader Chuan Lu, speaks to Astronergy’s ambition to become one of the defining solar brands of the future. 

As a subsidiary of China’s CHINT Group, one of the world’s foremost smart energy solutions providers, Astronergy is well placed to fulfil that aim.

1. JinkoSolar

Founded: 2006
HQ: Shanghai, China​​​​​​​
CEO: Charlie Cao

With Chinese firms responsible for 86% of the world’s solar panel production each and every year, it will be no surprise that a Chinese firm tops this month’s list. 

JinkoSolar sits at the top of today’s solar manufacturing hierarchy and is frequently ranking number one for volume of shipments and for technological innovation. 

From early adoption of half‑cut cells to the rapid rollout of TOPCon and bifacial modules, Jinko has time and time again turned cutting‑edge lab concepts into accessible, gigawatt‑scale products. Its global manufacturing network spans Asia, Europe, the Americas and several emerging markets, which gives the company a great deal of resilience against regional policy shocks and trade disputes. 

Lately, the firm has also begun expanding into the energy storage sector, while also improving its maintenance services. Today, it is evolving from a high‑volume module maker into a diversified clean energy giant – one that will heavily influence how quickly solar displaces fossil‑fuel generation in the years to come.
