Solar Star in California: the world’s largest photovoltaic solar power plant Solar Star, la plus grande centrale solaire photovoltaïque au monde, en Californie

Solar Star, one of the world’s largest photovoltaic power plants, is located under the California sun. Developed by our SunPower affiliate, it supplies electricity to approximately 255,000 homes.

In early 2013, our SunPower affiliate started working on the development of Solar Star, one of the largest solar power plants ever built. Owned by BHE Solar, the project is located in Rosamond, California.

The power plant, which came on line in 2015, provides solar electricity to approximately 255,000 homes in California via more than 1.7 million ground‑mounted high-efficiency SunPower solar panels.

SunPower provided turnkey management of the Solar Star construction site, and now operates and maintains the power plant. The project created approximately 650 jobs over a three-year period and generate millions of dollars for the local economy.

Higher efficiency with SunPower™ Oasis™ Power Plant technology

The Solar Star photovoltaic power plant features SunPower™ Oasis™ Power Plant technology. This solution integrates high-density power blocks designed to maximize energy production while preserving the landscape.

SunPower technology: the world’s most efficient panels

Featuring revolutionary Maxeon® technology, SunPower photovoltaic cells deliver unparalleled reliability, enabling SunPower to produce the most efficient solar panels in the market.

SunPower panels’ Maxeon® cells achieve this performance thanks to their fundamentally distinct characteristics:

  • Their solid copper foundation offers exceptional resistance to corrosion.
  • The front of each cell is free of any wiring or ribbon connectors, enabling the cells to absorb a maximum amount of light.
  • The connectors between each cell are particularly thick, improving resistance to thermal expansion and contraction caused by temperature fluctuations throughout the day.
