Revolutionizing the Contact Lens Industry: Manufacturer Secures Operations with Cutting-Edge Rooftop Solar TechnologyCalifornia-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, 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 affected. The project was designed, installed, and will be maintained by solar contractor ReVamp Energy, which incorporated battery energy storage into the microgrid. 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 installation will prevent losses incurred from spoiled production runs that can occur during power outages. Jay Cutting, president of ReVamp Energy, highlighted the importance of uninterrupted power for the manufacturing process, stating that any power reduction could potentially ruin an entire production run. To ensure continuous production, excess solar production will be stored in a 450 kW battery, providing backup power for up to 24 hours. The microgrid also includes a generator as an additional backup measure. ReVamp Energy has implemented custom-made switchgear that automatically switches the site’s energy supply to backup power in the event of a power 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. Cutting emphasized the use of SolarEdge technology in meeting the client’s requirements for high energy production, reliability, and intelligent control. By utilizing power optimizers and generating performance data, the microgrid can be operated and maintained efficiently.
