California-based contact lens manufacturer, Staar Surgical, is set to reduce operational costs 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 cost savings, the microgrid will provide energy resilience during times when the central utility grid is impacted. The project was designed, installed, and will be maintained by solar contractor ReVamp Energy, which incorporated battery energy storage into the microgrid. The system includes a 780 kW rooftop array with SolarEdge DC-optimized inverters, as well as capacity on two newly-constructed carports. With a total of 1,752 modules, the microgrid is anticipated to reduce Staar Surgical’s electricity costs by approximately 50%. Furthermore, the microgrid will help prevent losses incurred by spoiled production runs that can occur when power outages disrupt the manufacturing process. To ensure uninterrupted production, excess solar production will be stored in a 450 kW battery, providing backup power for up to 24 hours. The system also includes a generator for added reliability. A custom-made switchgear will automatically switch the site’s energy supply to backup power in the event of a power outage. Staar Surgical and ReVamp Energy will be able to monitor and manage the microgrid through the SolarEdge monitoring platform, which tracks key parameters such as solar energy production, consumption, and battery energy levels in real-time. Jay Cutting, president of ReVamp Energy, expressed confidence in the project’s success, citing SolarEdge technology as a crucial component in achieving high energy production, reliability, and intelligent control.
