REC solar panels vs Sunpower

Solar panels have become a popular choice for households and businesses looking to reduce their carbon footprint and energy bills. As a result, many companies have entered the solar panel market, each with its own unique technology and selling points. Two such companies that are often compared are SunPower and REC.

SunPower is a well-established American company that has been producing solar panels for over 30 years, while REC is a Norwegian company that has been in the solar industry for over 20 years. In this article, we will compare the two companies' solar panels in terms of their efficiency, durability, warranty, and overall value.

What we know about the REC solar panel brand

REC is a leading solar panel brand that was founded in 1996 in Norway. The company initially began as a wafer producer, supplying wafers to the semiconductor industry. In 2002, REC shifted its focus to the solar industry and began producing solar cells. By 2005, REC started manufacturing solar panels, which became the main focus of the company.

REC's solar panels quickly gained a reputation for their high efficiency and reliability. The company continued to expand its production facilities and opened its first solar panel manufacturing plant in Singapore in 2010. In 2014, REC opened a second manufacturing plant in Singapore and an additional facility in Norway.

In 2015, REC was acquired by the Chinese state-owned enterprise China National Chemical Corporation (ChemChina) for $640 million. ChemChina later merged with Sinochem in 2021 to create Sinochem Group.

Today, REC is headquartered in Norway and has a global presence, with production facilities in Singapore and Norway and sales offices in Europe, the Americas, Asia, and the Middle East. The company is known for producing high-quality solar panels with a focus on sustainability and innovation. In recent years, REC has also expanded into the energy storage market with its Smart Module technology, which integrates a battery pack into the solar panel.

What we know about the Sunpower Solar panel brand

SunPower is a leading solar panel brand that was founded in 1985 by Richard Swanson and Richard Crane, two Stanford University professors. The company was originally a research organization focused on solar technology and energy conversion. In 1988, SunPower developed its first solar cell with a record-breaking efficiency of 20%, a significant milestone in the solar industry at that time.

In the early 1990s, SunPower shifted its focus to commercializing its solar technology and began producing solar panels. By 1995, the company had launched its first commercial product, a 25-watt solar panel, and began to build a reputation for its high-efficiency solar technology.

In recent years, SunPower has expanded into the energy storage market with its SunPower Equinox Home Solar + Storage system, which combines solar panels with energy storage to provide reliable, clean energy for homes. SunPower is also focused on sustainability, with a goal to become a carbon-neutral company by 2025.
