Longi, hailing from China's Xi'an, was founded in 2000. With an impressive market capitalization of $30.33 billion, Longi has swiftly climbed the ranks to become one of the largest solar companies worldwide.

In terms of solar production, Longi's contributions are also impressive, with solar module production in 2022 surpassing 85.06 GW. It is partly due to the fact that it has a diverse geographical reach and works with customers from countries like the United States, Europe, and Australia.

Longi has earned a reputation for pushing the envelope in technological innovation. Their contribution to the monocrystalline silicon technology has revolutionized the solar industry and led to improvements in the efficiency and cost-effectiveness of solar panels, which are two of the most crucial factors that dictate the success of solar. This technological edge is also complemented by strategic collaborations, such as their partnerships with prominent companies worldwide.


SunPower, with its roots in Silicon Valley, was founded back in 1985. This solar company has a market capitalization of $1.84 billion.

SunPower's solar installations are wide-reaching, servicing both residential and commercial sectors globally. The company's efforts range from small rooftop solar systems to the largest solar farms in the US, such as the 579 MW Solar Star Projects in California.

What sets SunPower apart is its commitment to technological excellence. The company has brought some of the most efficient solar panels to the market, with their best models reaching impressive conversion efficiencies of up to 22.8%. Their patented Maxeon solar cell technology, which combats degradation and enhances durability, has set new standards in the solar industry.

In terms of collaborations, SunPower has formed strategic alliances with leading organizations, including Ford and KB Home, to bring solar to wider audiences.

Despite the headwinds of changing regulatory environments and stiff competition, SunPower's dedication to solar technological advancements, strategic alliances, and vast industry experience equip them well for the future.
