eSolar has developed a cost-effective utility-scale CSP power plant that is based on mass-manufactured components and designed for rapid construction,
uniform modularity, and unlimited scalability. The eSolar approach marries a low-impact, pre-fabricated design with patent-pending computer software and
elegant engineering solutions to provide solar electricity ranging from 46 MW to over 500 MW. The eSolar® solution delivers cost-competitive solar
energy in response to growing worldwide energy demands.
Power Tower Technology A 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.
2. Patented Heliostat Design
The eSolar Building Block A 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 a minimum of training. Low wind profile design allows fields of eSolar® heliostats to be installed faster than any competitive CSP solutions.
3. Modular Field Layout
Cost-Based Design Thousands 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 thermal receiver mounted atop a central tower.
The sub-field design optically optimizes the layout to maximize the harvested thermal energy.
4. Scalable Units
The eSolar Solution A 46 MW eSolar® power unit consists of 12 towers
(each with its own north-south heliostat sub-field), a turbine generator set,
and a steam condenser. 46 MW power units fit on approximately 100 hectares (250 acres). eSolar can construct multiple 46 MW units scalable to any required size of output.
