SunPower overview: History, subsidiaries, and technology

The history of SunPower started in 1970, when Dr. Richard Swanson, the co-founder of the company, chose solar energy to deal with the oil crisis in the country. The company was finally created in 1985, as a result of two grants awarded by the Electric Power Research Institute and the U.S. Department of Energy.

Throughout its history, SunPower has heavily focused on research and adapting cutting-edge solar technology available in the industry, to create its outstanding products. As a result, SunPower has created world-record solar cells used in all types of applications like residential, commercial, utility-scale, and even special projects created by NASA.

SunPower does not only provide high-quality PV products, but a complete range of energy solutions including generation, monitoring, control, and storage. The company is currently positioned as one of the leading solar companies in the U.S. solar industry.

Understanding more about SunPower, how they work, and its technology will provide you with greater insight into the reach of the company and how its products might suit your needs.

SunPower or Maxeon Solar: Who is who?

SunPower was created as a U.S. solely based company, focusing on selling PV solutions only to the U.S., but this did not limit its reach. In 2020, Maxeon was created as a spin-off company of SunPower, allowing it to sell PV solutions to customers all over the world, by dealing with SunPower-branded products on an international scale, delivering solar energy solutions to Asia, Europe, and more than 100 countries all over the globe.

Maxeon currently holds more than 1,000 solar patents and has achieved revenue surpassing $700 million by selling high-quality PV products all over the world. This company has partnered with over 1,400 solar sales and installers to extend its reach within different countries, granting homeowners across the globe the possibility to enjoy high-quality PV solutions with fully integrated solar energy systems.

SunPower Technology

SunPower high-efficiency solar panels are manufactured using some of the best monocrystalline silicon modules in the market. The company integrates this high-quality material with highly-developed solar cell structural designs like IBC solar cell technology and shingled technology to create their high-quality products.

IBC Solar Cell Technology

Interdigitated Back Contact (IBC) solar cell technology is one of the most advanced and cutting-edge manufacturing technologies available for SunPower solar cells. The technology places solar energy conversion at the back of the cell, also relocating the electrodes at the rear side of it.

Since IBC SunPower solar cells have relocated the frontal electrodes at the back, they feature a larger useful area for photons to impact, which results in the SunPower high-efficiency solar panels. IBC SunPower solar cells are up to 20% more efficient than Passivated Emitter and Rear Contact (PERC) solar panels.

With this technology, SunPower has been able to create highly aesthetic solar panels with no visible contacts at the front, commonly known as the SunPower All Black solar panels. Installing these modules at homes or any other locations, will not disrupt the superiorly aesthetic aspect of the place while providing the capacity to generate solar power.

Shingled Technology

Shingled technology is one of the latest manufacturing methods for creating solar modules. By combining it with mono-PERC technology, SunPower has created the Maxeon Performance modules that can reach up to 625W in solar power generation with a single module, featuring a 21.2% conversion efficiency.

SunPower Performance modules manufactured with shingled technology, are robust solar panels featuring resistance to thermal stress, humidity, and Potential Induced Degradation (PID). The circuitry design can also mitigate hotspots while increasing energy production under unfavorable conditions.

Aside from increasing conversion efficiency by reducing whitespace between SunPower solar cells, Shingled technology increases flexibility for the modules, making them more durable and resistant.

Are SunPower solar panels the right option for you?

SunPower PV modules feature cutting-edge technology, outstanding performance, and superior aesthetics, making them ideal for practically any application, but especially for residential.

SunPower solar panel price tends to have a slightly higher cost than traditional low- and mid-efficiency solar panels, but the high conversion efficiency, great durability, low power degradation, and long warranty, provide benefits surpassing the price difference between modules.

SunPower has tailored-designed solar panels and other PV solutions, suited for residential, commercial, and utility-scale applications. SunPower products are the preferred option picked by many investors, project developers, electric utilities, homeowners, government entities, and retail businesses.

If you are looking for extremely high-performance modules designed for the most demanding applications and featuring highly aesthetic designs, then SunPower panels are the right fit for you.
