Solyndra Inc. recently received a $535 million federal loan guarantee from the U.S. Department of Energy to build the plant, according to the company. The company already operates a similar plant in Fremont, but the new one will be about double the size.
The company has estimated the new facility will create about 3,000 temporary construction jobs and 1,000 long-term production jobs.
It is still under construction, but officials hope to open it for production later this year.
Solyndra manufactures solar products primarily for commercial use on flat rooftops.
Its cylindrical photovoltaic systems are designed to catch both direct sunlight and light reflected off so-called "cool roofs" that have been painted white, according to the company.
Boxer will tour the facility at noon.
