Revolutionizing the Contact Lens Industry: Manufacturer Secures Future with Rooftop Solar PowerCalifornia-based contact lens manufacturer, Staar Surgical, is set to make significant cost savings 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 reducing costs, 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, SolarEdge DC-optimized inverters, and 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 company will avoid losses caused by power outages during the manufacturing process, which can ruin production runs and result in significant financial setbacks. To address this issue, a 450 kW battery will store excess solar production, providing backup power for up to 24 hours depending on the facility’s load requirements. The microgrid also features a generator to ensure uninterrupted production. ReVamp Energy has 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 from a single platform. Jay Cutting, President of ReVamp Energy, expressed confidence in the project, highlighting the use of SolarEdge technology to maximize energy production and ensure efficient operation and maintenance of the microgrid. With this innovative solution in place, Staar Surgical is poised to achieve significant cost savings while maintaining uninterrupted production.
