eSolar power plant technology utilizes small, flat mirrors which track the sun with high precision and reflect the sun's heat to a tower-mounted receiver, which boils water to create steam. This steam powers a traditional turbine and generator to produce solar electricity.

Power Tower TechnologyA field of sun-tracking heliostats reflects solar heat to a thermal receiver mounted atop a central power tower. The focused heat boils water within the thermal receiver and produces steam. The plant pipes the steam from each thermal receiver and aggregates it at the turbine, powering a power generator. The steam then reverts back to water through cooling, and the process repeats.
The eSolar Building BlockA small and mass-manufactured heliostat is the building block of the eSolar™ solution. eSolar designed the heliostats for deployment in pre-fabricated "heliostat sticks" that can be installed easily with minimal skilled labor. Low wind profile design allows fields of eSolar™ heliostats to be installed faster than any competitive CSP solutions.
Cost-Based DesignThousands of systematically spaced heliostats combine to form the eSolar™ modular field, comprised of north and south facing mirror sub-fields. Both mirror fields concentrate sunlight to a patented dual-port eSolar™ receiver atop a central tower. The sub-field design optically optimizes the layout to maximize the harvested thermal energy.
The eSolar SolutionA 46 MW eSolar™ power unit consists of sixteen towers (each with its own north-south heliostat sub-field), a turbine generator set, and a steam condenser. 46 MW power units fit on a 1/4 section, or 160 acres. eSolar can construct multiple 46 MW units to scale to any size to meet customer needs.

Solar Thermal Heats Up
ESolar expects to start up its large solar thermal plant soon.
Power mirrors: ESolar's solar thermal test bed in Lancaster, CA, is set to start producing power for the grid later this summer. The field's 24,000 mirrors can produce five megawatts of electricity by reflecting solar radiation to tower-based water boilers that drive turbines.
