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 in development, is located under the California sun. Developed by our solar power affiliate SunPower, it supplies electricity to approximately 255,000 homes since mid 2015.

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

Our goal is to supply electricity to approximately 255,000 homes through 1.7 million SunPower high-efficiency panels.

The power plant is entirely connected to the electricity distribution grid since mid 2015 and began supplying electricity generated by the panels in January 2014.

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

Solar photovoltaic technology has two advantages: it’s quick to install and it can begin generating power to the grid before a plant is fully constructed

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.
