Staar Surgical, a contact lens manufacturer based in California, 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 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. This 1,752 module system is anticipated to reduce the contact lens 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 address this issue, a 450 kW battery will store excess solar production, providing backup power for up to 24 hours. The microgrid also features a generator to ensure continuous 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, enabling Staar Surgical and ReVamp Energy to track key parameters in real-time from a single platform. Jay Cutting, President of ReVamp Energy, praised SolarEdge technology for its role in achieving high energy production, reliability, and intelligent control. The installation of this solar microgrid demonstrates Staar Surgical’s commitment to sustainable and cost-effective energy solutions.
