Revolutionizing Contact Lens Manufacturing: How Rooftop Solar Ensures Sustainable OperationsStaar Surgical, a contact lens manufacturer based in California, is set to significantly reduce operational costs and enhance the reliability of its operations by installing a rooftop solar microgrid. The 1.1 MW grid-tied microgrid, located at the company’s production facility in Lake Forest, is expected to save $325,000 in annual electricity bills while providing energy resilience during disruptions to the central utility grid. ReVamp Energy, a solar contractor, designed, installed, and will maintain the microgrid, which includes battery energy storage. The system, consisting of a 780 kW rooftop array and two newly-constructed carports, is projected to cut the manufacturer’s electricity costs by approximately 50%. Additionally, the microgrid will prevent losses from spoiled production runs caused by power outages during the manufacturing process. To ensure uninterrupted production, excess solar production will be stored in a 450 kW battery, and a generator is also included in the system. The microgrid is equipped with custom-made switchgear that automatically switches the energy supply to backup power in the event of an outage. Staar Surgical and ReVamp Energy will be able to monitor key parameters such as solar energy production, consumption, and battery energy levels in real-time through the SolarEdge monitoring platform. Jay Cutting, president of ReVamp Energy, emphasized the importance of SolarEdge technology in achieving high energy production, reliability, and intelligent control. The installation of the microgrid aligns with Staar Surgical’s commitment to efficient and cost-effective operations.
