ESolar Heliostat Solar Tower Modules Score
Each pre-fabricated module consists of several solar towers each associated with thousands of heliostats, or mirrors. The mirrors precisely track the sun over the course of the day and reflect light to a receiver at the top of each tower. The concentrated light boils water in a central receiver, routing the steam to a traditional turbine to produce electricity. eSolar’s solar thermal technology is unique in that it uses shorter towers, small mass-manufactured mirrors and advanced tracking software, achieving economies of scale within a minimal footprint and easy connection to transmission lines. __SourceMore information about the deal at LATimes
ESolar's modular heliostat technology appears to share many advantages with BrightSource solar thermal technology. Both technologies should allow quicker and cheaper construction, with lower operating costs and lower demands for on-site cooling water. Solar thermal is currently superior to photovoltaic solar due to higher efficiences and much cheaper storage options.
