Revolutionizing Contact Lens Manufacturing: Solar Power Ensures Sustainable OperationsStaar Surgical, a contact lens manufacturer based in California, is set to improve its operational efficiency and reduce costs by implementing a rooftop solar microgrid. The 1.1 MW grid-tied microgrid, installed on the company’s production facility in Lake Forest, is expected to save $325,000 in annual electricity bills and provide energy resilience during grid disruptions. 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 and additional capacity on newly-constructed carports. With a total of 1,752 modules, the microgrid is projected to cut the manufacturer’s electricity costs by approximately 50%. Furthermore, the microgrid will prevent losses caused by power outages during the manufacturing process, which can lead to spoiled production runs. To ensure uninterrupted production, excess solar energy will be stored in a 450 kW battery, providing backup power for up to 24 hours. The system also includes a generator. ReVamp Energy has developed custom-made switchgear that automatically switches the site’s energy supply to backup power in case 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 levels in real-time from a single platform. Jay Cutting, president of ReVamp Energy, praised SolarEdge technology for its contribution to high energy production, reliability, and intelligent control. The implementation of this solar microgrid demonstrates Staar Surgical’s commitment to sustainable and cost-effective operations.
