California-based contact lens manufacturer, Staar Surgical, is set to reduce operational costs and improve the reliability of its operations with the installation of a rooftop solar microgrid. The 1.1 MW grid-tied microgrid, located at the company’s production facility in Lake Forest, is expected to result in annual electricity bill savings of $325,000. In addition to cost savings, the microgrid will provide energy resilience during times when the central utility grid is impacted. The project was designed, installed, and will be maintained by solar contractor ReVamp Energy, which incorporated battery energy storage into the microgrid. The system consists of a 780 kW rooftop array, SolarEdge DC-optimized inverters, and two newly-constructed carports. With a total of 1,752 modules, the microgrid is estimated to reduce Staar Surgical’s electricity costs by 50%. Furthermore, the microgrid will prevent losses incurred by spoiled production runs that can occur when power outages interrupt the manufacturing process. ReVamp Energy has also developed custom-made switchgear that automatically switches the site’s energy supply to backup power in the event of an outage. The microgrid can be managed through the SolarEdge monitoring platform, allowing Staar Surgical and ReVamp Energy to track key parameters such as solar energy production, consumption, and battery energy levels in real-time. Jay Cutting, president of ReVamp Energy, emphasized the importance of SolarEdge technology in achieving high energy production, reliability, and intelligent control for the microgrid.
