Revolutionizing the Contact Lens Industry: Manufacturer Secures Future with Solar PowerCalifornia-based contact lens manufacturer, Staar Surgical, is set to reduce operational costs and enhance 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, California, 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 affected. ReVamp Energy, a solar contractor, designed, installed, and will maintain the microgrid, which includes battery energy storage. The system consists of a 780 kW rooftop array with SolarEdge DC-optimized inverters, as well as additional capacity on two newly-constructed carports. With a total of 1,752 modules, the microgrid is projected to reduce Staar Surgical’s electricity costs by approximately 50%. Furthermore, the microgrid will prevent losses incurred from spoiled production runs that can occur when power outages disrupt the manufacturing process. To ensure uninterrupted production, excess solar production will be stored in a 450 kW battery, providing backup power for up to 24 hours. The system also includes a generator as an additional backup measure. ReVamp Energy has implemented 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, enabling Staar Surgical and ReVamp Energy to track key parameters such as solar energy production, consumption, and battery energy levels in real-time from a single platform. Jay Cutting, president of ReVamp Energy, expressed confidence in the project’s success, highlighting the use of SolarEdge technology to maximize energy production and ensure efficient operation and maintenance of the microgrid.
