What is eSolar?
Founded in 2007 and based in Burbank, California, eSolar specializes in Concentrating Solar Power (CSP) technology. Its core product, the solar collector system (SCS), is designed for modularity and scalability, aiming for breakthrough cost reductions through advanced software engineering and a low-impact, pre-fabricated form factor. eSolar's power tower plant-level solution, when coupled with partner-provided solar receivers, offers high efficiency and meets demand for reliable, dispatchable, and cost-competitive solar-generated thermal energy. The technology is applicable to both power generation and non-power applications, including enhanced oil recovery, water desalination, and industrial process heat.
