Founder and Chairman Bill Gross explains the unique eSolar solution and leads a tour through the Sierra SunTower commercial facility located in Lancaster, California.

Time-lapse footage of field assembly highlights how eSolar's modular design and pre-assembled components deploy quickly and efficiently, delivering cost-competitive solar energy in response to growing worldwide demand.

Heliostats are coordinated to track the sun using a proprietary active control system that constantly monitors the performance of each heliostat within the field, resulting in unprecedented pointing accuracy and high thermal concentration ratios.

On August 5, 2009, eSolar launched Sierra SunTower, heralding a new era of low-cost solar energy.
