More >>eSolar develops, constructs and deploys modular, scalable solar thermal power plants. eSolar's technology, per the company, aims to marry a low-impact, pre-fabricated form factor with advanced optics and computer software engineering to meet the demands of utilities of any size for clean, renewable and cost-competitive solar energy. It is an Idealab company founded in 2007 to develop, construct and deploy modular, scalable solar thermal power plants. eSolar's approach marries a low-impact, pre-fabricated form factor with advanced optics and computer software engineering to meet the demands of utilities of any size for clean, renewable and cost-competitive solar energy. By focusing on the key business obstacles that have characterized large solar installations â price, scalability, speed of deployment and grid impact â eSolar has developed a proprietary solution to make a dramatic reduction in the cost of solar thermal technology. eSolar is based in Pasadena, California Per the company, it's technology is predicated/differentiated based on four characteristics: eSolar's Power Tower Technology is 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. eSolar offers a small and mass-manufactured heliostat which 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. Per eSolar, 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 patented dual-port eSolar⢠receiver atop a central tower. The sub-field design optically optimizes the layout to maximize the harvested thermal energy. And ultimately, a 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 approximately 200 acres, or 80 hectares. eSolar can construct multiple 46 MW units to scale to any size to meet customer needs.
