Maxeon Solar Technologies requests a new air quality permit in Application Permit Number #3516
December 07, 2023

Maxeon Solar Technologies is requesting a new construction permit to construct and operate a new photovoltaic (PV) solar panel manufacturing facility (Facility). Photovoltaic solar panel cells are produced by delivering gases and liquid chemicals to processing tools that perform various processes on a silicon wafer substrate within the Cell Fabrication. The cells are then grouped into modules and interconnected to allow the panel to produce electricity within the Module Production area.  The Facility is expected to manufacture about 5.8 million solar panels, corresponding to 3.5 gigawatts of power annually.  Maxeon is requesting to operate 8,760 hours per year.

The proposed manufacturing processes will include two (2) main production areas: The Cell Production area (CellFab) and the Module Production area (ModCo). Air emissions from the manufacturing processes will be controlled with scrubbers and other point of use control systems.

  • Three (3) Acid Scrubbers each rated at 58,596 cubic feet per minute (cfm)
  • Three (3) Alkaline Scrubbers each rated at 40,906 cfm;
  • Two (2) Silane Scrubbers each rated at 9,437 cfm 


The facility will also include ancillary equipment such as natural gas boilers, diesel generators, fire pump and cooling towers.

  • Four (4) 900 hp (30.1 MMBTU/hr) natural gas fired boilers;
  • Three (3) 2,682 hp (2,000 kW) diesel-fired emergency engines;
  • One (1) 542 hp diesel-fired fire pump;
  • Eight (8) cooling Towers each rated at 4,000 gallons per minute (gpm);
