The global solar industry is dominated by a handful of manufacturers with massive production capacity and proven technology. Here are the 10 companies leading that charge, ranked by scale, innovation, and market reach.
1. Jinko Solar
The list starts with a very prolific solar panel producer and seller in the world with headquarters in Shanghai, China.
The company started as a wafer manufacturer in 2006, but in only ten years, it became the most reliable solar panel manufacturer in the world.
In 2018, they shipped 11.4 GW of modules around the world with total revenue of US$3.64 billion (although lower than 2017), making them with certainty the primary producer in the world.
Now they have an installed production capacity of about 18 GW around the globe.
The company works on monocrystalline and photovoltaic modules, but recently introduced the black eagle, a nano-scale module that absorbs 99.7%, operates at peak performance, and exceeds light absorption of standard panels on cloudy days.
This solar energy company holds an international reach to the whole world, including customer bases in all continents.
The company has 13,500 employees across six manufacturing plants and 15 overseas subsidiaries in the Middle East, Asia, Europe, America, and Australia.
They keep a pretty average price of $2.5/$3 per watt. A good value for the home solar market, especially if you’re exploring whether rooftop solar is right for your home.
2. LONGi Solar
The company is one of the largest mono-crystalline solar modules producers in the world, with the main headquarters stationed in Xi’an, China.
The member of the SMSL has officially inaugurated its newest high-efficiency module factory of monocrystalline panels in Chuzhou, China, with a power of 5 GW and an investment of $328 million.
LONGi Solar is planning on setting up another 1 GW solar panel plant in Andhra Pradesh, India, to increase their sales and hold their superiority in the Indian market.
Thanks to these new numbers, LONGi is expected to break the 13 GW barrier and has the objective of producing 45 GW by 2021. The company was awarded first place to the solar panel with the best performance in 2018 by TÜV Rheinland, establishing itself as the company with the highest-end solar panels.
They’re always present in the Tier-1 list by Bloomberg and were selected as one of the top performance brands by the laboratory DNV-GL.
3. JA Solar
JA Solar is among the dominant solar energy companies, founded in 2005. This is another Chinese giant of solar panel manufacturers, with its main quarters in Shanghai and important quarters in Ningjin.
They have an impressive line of business, including solar power systems, monocrystalline and photovoltaic panels of their design, manufacture, and sales in more than 100 countries.
With outstanding growth, the company has managed to install a total solar capacity of around 23 GW around the world, achieving US$3 billion in revenues across the globe.
JA Solar sees itself as an innovation company in the industry of solar technology. They have a constant development holding themselves 6 to 12 months ahead of the competition.
After the Chinese government and hundreds of investments subsidized the company, they transformed themselves into the first company to start mass production of high-efficiency 300-watt photovoltaic panels.
They built the biggest floating photovoltaic farm in China.
JA solar panel company has received massive recognition from specialized, domestic, and international agents as a global manufacturer of high-end photovoltaic products.
4. Canadian Solar
Canadian Solar is by far the largest solar industry and one of the top solar panel manufacturers.
At the same time, as the largest solar panel manufacturer in America, it is a fierce competitor against Chinese companies in the worldwide market.
CS has its headquarters in Ontario, Canada.
Still, they have facilities in South America, where they have recently won a 190.5 MW project in Brazil, Southeast Asia, and China, where their systems are produced and shipped non-stop (wafers, ingots, PV panels, etc.).
The solar company has around 24 GW of photovoltaic panels installed in all continents and at least 9.5 GW in shipments, making them part of the top solar companies.
The enterprise considers its main challenge to produce higher power with less space to have more kilowatts in the least space possible.
The newest generation of solar panels produced by Canadian Solar incorporates their recently developed wave of solar panels that provide a major power outlet by size.
Interestingly, the corporation is known mainly for being one of the few competing against the Asian giants such as LONGi, JA Solar, and Jinko Solar but also because of their innovating photovoltaic solar panels, prioritizing quality before quantity.
5. Trina Solar
Another high-end brand that is among the best solar companies is Trina Solar, a leading provider of solar services, with 11 GW of power capacity installed already.
The Chinese solar company, stationed in Jiangsu, is significant, as most solar panels in India are a product of this enterprise.
For some reason, the company’s 2018 statistics are difficult to find, but the company has already installed 11 GW of solar capacity.
Trina solar business has focused on improving the efficiency of solar energy system panels, especially the effectiveness of the solar cell, referring to the portion of energy in the form of solar light that can be transformed into electricity using photovoltaic power.
The corporation has developed its own solar power system, a monocrystalline solar panel, with an efficiency rate of 22.61% and a polycrystalline panel with a rate of 21.25% in labs, closing the gap between both innovating technologies, taking into account that the first panel created had an efficiency rate of 6%.
6. SunPower Corp
SunPower Corp has been a global leader in solar power system innovation for more than 30 years. Stationed in Silicon Valley, the company’s panels have generated an incredible amount of 18 million MWh to date.
With an efficiency of 22.7%, the brand controls the residential solar panel with the highest effectiveness in the market. The company focuses on solar energy for the urban, commercial, and public market, which is great news.
Environment-friendly materials are especially hard to get. SunPower Corp is one of the few top-notch brands with the Cradle to Grave certification, meaning the materials with which the panels are built are safe for humans and the environment but most importantly, recyclable.
Ironically, Total S. A, one of the biggest oil companies in Europe, is the major investor of SunPower, owning 66% of their shares.
Proving once again that even oil brands know that Solar Energy is the future. If you’re building a smaller system at home, a solar micro-inverter is worth considering alongside panels from companies like SunPower.
7. Hanwha Q Cells
With main offices in Seoul, Korea, and Thalheim, Germany, Hanwha Q cells positions itself in the top Solar Energy brands with only 4 years of operation as it began production in 2015 when Q cells (a German brand) joined the Chinese Hanwha group, manufacturing mainly premium photovoltaic panels.
This solar power industry produces residential and commercial properties, but solar panel production is also thriving for the engineering and construction sector, managed by the EPC division.
Hanwha Q Cells has a unique patented technology called Q.ANTUM that improves the energetic performance in conditions of poor light when the climate is cloudy or on bright days of autumn and summer when the sun is not that strong in the sky.
Currently, the company is the principal Asian supplier for the Japanese and European markets, but with plans of soon opening themselves to new markets as they control two huge production plants.
8. First Solar
Stationed in Tempe, Arizona, the American reputable solar company is known for its unique photovoltaic panels using Thin Film Solar cells and their installed solar power of 17 GW around the world.
Thin-Film Solar cells are second-generation energy technology manufactured by using one or more thin layers of photovoltaic material over glass, plastic, or metal; the benefits of such technology are a more flexible panel that can be incorporated into construction materials such as windows or roofs.
These panels are lighter than the traditional standard and heavy panels.
This technology is also used with more rigid panels where the layer of photovoltaic material is in between two layers of materials, especially in the extensive photovoltaic farms in the world.
Although their technology is even cheaper than standard c-Si panels, one must take into account that there is a small efficiency loss, but it’s up to the buyer what they consider more vital.
The company is also known for its vast recycling campaign and its extensive farms in the US, Germany, Spain, Abu Dhabi, and Canada.
9. GCL- System Integration
Another Chinese giant wins its place among the top solar companies of the world. Based in Hong Kong and founded in the 90s, this brand has grown steadily for 30 years.
Currently, they’re trying to insert themselves into the heavily monopolized Indian market to compete with other Chinese counterparts LONGi solar, although they managed to receive the BIS (Bureau of Indian Standards) Certification of Photovoltaic Modules.
The group employs 30,000 people around the globe.
It holds five-module productions in China and one in Vietnam, counting up to an 8 GW production capacity and winning its rightful place as a world-class solar panel producer.
Bloomberg qualified GCL-SI among the top six-module suppliers for three consecutive years. The company’s publicity slogan is Design, Product, and Service.
Still, it’s up to us to decide if they stay true to it.
10. LG Energy
Last but not least comes LG Energy, part of LG Electronics, and a key player in the solar market. The South Korean brand produces photovoltaic panels and energy storage solutions.
Their panels are known for their fantastic reliability and performance, with some unique characteristics that improve the panel’s general performance. Pairing them with quality solar storage batteries can maximize your return on investment.
A 25-years product and performance warranty is offered with every LG panel.
Thus, their popularity in Europe, the US, and Australia has grown over the years. They dominate the Australian market.
Take note of LG Neon 2 solar panels, a highly efficient solar panel that the company has introduced recently.
It can produce and absorb energy from both sides of the cell, highly increasing the panel’s performance.
These solar panels are in high demand in the market because of their innovative technology but also because of the panel’s striking look (Black anodized aluminum frames) and their flawless and exceptional construction quality.
LG Solar produces mainly mono-crystalline cells because of their low degradation level compared to polycrystalline panels, as opposed to other brands that manufacture both technologies.
Frequently Asked Questions
Which country leads the world in solar panel manufacturing?
China dominates global solar panel manufacturing by a wide margin. Companies like Jinko Solar, LONGi, JA Solar, and Trina Solar are all headquartered there and collectively account for the majority of worldwide module production.
China’s advantage comes from massive government investment, lower labor costs, and vertically integrated supply chains that cover everything from polysilicon refining to finished panel assembly.
What is the difference between monocrystalline and polycrystalline solar panels?
Monocrystalline panels are made from a single silicon crystal structure, giving them higher efficiency rates and a sleek black appearance. Polycrystalline panels use multiple silicon fragments melted together, resulting in slightly lower efficiency but a more affordable price point.
Most top manufacturers now favor monocrystalline technology because the efficiency gap has widened while production costs have dropped.
How do I choose between these solar companies for a home installation?
Start by checking which brands your local installer carries, since availability varies by region. Compare warranty length, panel efficiency, and degradation rates across the brands on this list.
If you’re still weighing whether solar panels are worth it for your situation, factor in your roof size, local electricity rates, and available incentives before committing to a specific manufacturer.
Can solar panels from these companies power an entire house?
Yes, but the number of panels you need depends on your household energy consumption, roof space, and local sunlight hours. A typical home requires between 15 and 25 panels from any of these manufacturers to cover its full electricity demand.
Pairing your panels with solar garden lights for outdoor areas can also reduce the load on your main system.
