California-based contact lens manufacturer, Staar Surgical, is set to 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 around $325,000 in annual electricity bills while providing energy resilience during disruptions to the central utility grid. The microgrid, designed, installed, and maintained by solar contractor ReVamp Energy, incorporates battery energy storage and a 780 kW rooftop array with SolarEdge DC-optimized inverters. Additionally, two newly-constructed carports house the remaining capacity of the 1,752 module system, resulting in a 50% reduction in electricity costs for the contact lens manufacturer. The microgrid will also prevent losses incurred by 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, providing up to 24 hours of backup power. The system also includes a generator. A custom-made switchgear will automatically switch the site’s energy supply to backup power during outages. Staar Surgical and ReVamp Energy will be able to monitor and manage the microgrid through the SolarEdge monitoring platform, tracking key parameters such as solar energy production, consumption, and battery energy levels in real-time. Jay Cutting, President of ReVamp Energy, emphasized the use of SolarEdge technology in meeting Staar Surgical’s requirements for high energy production, reliability, and intelligent control.
