Cal Tech

California Institute of Technology
1.18 MW DC

The California Institute of Technology, a private research university located in Pasadena, California, is host to a 1.18 MW DC roof-mounted solar installation system capable of generating 1,718,751 kWh of green energy annually. The system is comprised of polycrystalline solar modules installed on buildings of Baxter Hall, Wilson Parking Garages, Braun Gym, IPAC Laboratory, Cahill Center, and Annenberg Center. According to Pasadena Water & Power, Caltech currently owns the largest solar power installation in the city of Pasadena. At no capital outlay from the host, PES financed and developed the systems by utilizing conventional financing and equity raised through federal renewable energy tax credit. PES will be providing the energy to the university a significantly lower rate than offered by the municipal utility, saving Caltech more than $100,000 a year. The total project is estimated to generate 1,718,751 kWh, eliminating more than 1,234 metric tons of CO2 emissions annually.

The reduction of 1,234 metric tons of CO2 is equivalent to:

  • Taking 236 passenger cars off the roads for the year
  • Electricity used to power 150 homes for one year
  • Carbon sequestered by 31,650 tree seedlings grown for 10 years
  • 6.4 railroad cars worth of coal
