Top 10 Solar Companies

“There is no conflict between profitable business and sustainable business — both go hand in hand,” believes Ronen Faier, Chief Financial Officer at SolarEdge.

The solar industry is one of the fastest-growing industries. Today, over two million homes in the United States use solar energy, and these numbers are expected to grow over the coming years both in the US and globally, despite the increasing cost of photovoltaic (PV) panels.

As the global energy transition develops, the world’s largest companies are working alongside the individual homeowner to swap to renewable energy where possible, and we’ve taken a dive into some of the top global companies providing solar energy and contributing to achieving a zero-carbon footprint.

Seoul based Qcells runs the world's first production line dedicated to perovskite-silicon tandem solar cells in Jincheon.

The company has committed a substantial investment of US$100m to bring this next-generation solar cell technology — which has the potential to boost efficiency by 50-75% compared to standard solar panels — from the realm of lab tests and academic research to practical application.

“This investment in the Jincheon facility marks an important step in securing technological leadership,” said Justin Lee, CEO of Qcells.

“With a global R&D network spanning from Korea, Germany and the US, Qcells will ramp up its efforts to produce high-efficiency advanced tandem cells.”

Solar energy company Sunrun Inc. develops, manufactures, sells, instals and maintains solar energy systems in 22 states, Washington DC and Puerto Rico. Founded over 15 years ago, its products range from large-scale energy projects to rooftop panels and batteries for homes, including the Tesla Powerwall.

It was selected by Puerto Rico to rebuild its energy systems and to create a large-scale energy storage solution to address concerns over an increase in severe weather events and damages.

Maxeon Solar Technologies specialises in the production and sale of solar energy products, including solar cells, modules, microinverters, and storage solutions. It is headquartered in Singapore and has a global presence in over 100 markets. Maxeon’s Mexicali, Mexico module production facility is also first and only certified, zero-waste-to-landfill solar panel factory.

Originally part of SunPower Corporation, Maxeon spun off in August 2020 to become an independent entity, now operating the SunPower brand in all global markets and the Maxeon brand in the United States, Canada and Japan.

Going beyond the world-renowned solar panels, Maxeon is developing a complete suite of intelligent energy solutions that include batteries, chargers and other best-in-class services.

Established in 2006, SolarEdge developed the DC optimised inverter solution that changed the way power is harvested and managed in photovoltaic (PV) systems.The company now builds and distributes equipment and technology for photovoltaic arrays, alongside providing optimisation services and monitoring solutions for photovoltaic systems.

Based in Herzliya, Israel, SolarEdge monitors sites in over 130 countries, and over 2,600,00- systems globally.

SolarEdge claimed a record annual solar revenue of $2.92 billion in 2022 and anticipates continued growth after seeing its revenue increase by 63% from 2021.

“Our mission is to shape the future of sustainable energy - focussing on clean energy production, management, storage and e-Mobility,” says Zvi Lando, CEO.

“This reflects our commitment to protecting the environment for generations to come.”

SunPower specialises in designing solar solutions, providing photovoltaic solar energy for residential properties in all 50 US states. Founded in 1985 and headquartered in California, the company achieved a remarkable 63% year-over-year growth rate in 2022, growing revenue from US$347m in 2021 to US$492m in 2022.

SunPower is partnered with General Motors to be the exclusive installer of electric vehicle chargers for the company.

"We are proud to work alongside GM, a stalwart in American innovation, to seamlessly connect home energy and electric vehicles. This is a vital next step toward making an all-electric lifestyle easy and even more beneficial," says Peter Faricy, SunPower CEO.
