Facebook is planning to create both electricity and hot water with a solar energy system at its new Menlo Park, Calif., headquarters.
With the capacity to generate 10 kw of electricity and 50 kw of thermal energy, the system from Cogenra Solar is relatively small. But its dual function makes it more cost-effective than a PV-only solar system, according to Cogenra CEO Gilad Almogy, quoted in the San Francisco Chronicle.
