What is eSolar?
Founded in 2007 and headquartered in Burbank, California, eSolar specializes in the development of modular and scalable Concentrating Solar Power (CSP) technology. The company's core product, the solar collector system (SCS), integrates pre-fabricated form factors with sophisticated software engineering to achieve significant cost reductions in solar thermal energy production. Unlike traditional, large-scale solar installations, eSolar's modular power tower design offers a highly efficient, dispatchable energy solution. This versatility allows the technology to serve diverse sectors, including utility-scale power generation, water desalination, enhanced oil recovery, and industrial process heat, positioning the company as a critical player in the renewable energy infrastructure market.
