Staar Surgical, a producer of implantable lenses utilized in ophthalmic surgical procedures, has inaugurated a 1.1-MW grid-tied microgrid on its manufacturing facility in Lake Forest, California. Now operational, the system was put in to fulfill three targets: Scale back vitality prices, enhance sustainability, and safeguard manufacturing within the occasion of grid outages brought on by excessive climate occasions.

The microgrid is powered by a 780-kW photo voltaic system with a SolarEdge DC-optimized inverter situated on the power’s roof and two newly constructed carports. The 1,752-module system is predicted to chop Staar Surgical’s vitality prices by roughly 50%, representing an annual saving of around $325,000.
“Manufacturing contact lenses is an extremely energy-intensive course that requires every lens to be heated in an industrial kiln constantly for a number of days,” stated Jay Slicing, Snr., president of constructing and photo voltaic contractor, ReVamp Energy, which designed, put in, and can preserve the microgrid. “Any discount in energy of quite a lot of seconds has the potential to smash a whole manufacturing run, resulting in losses of doubtless a whole lot or hundreds of {dollars}. The rising frequency of pink flag climate occasions in California necessitated that Staar Surgical tackle the mission-critical problem of figuring out an economical and sustainable methodology to safeguard manufacturing.”
Extra photo voltaic vitality produced in the day might be saved in a 450-kW battery to energy the location’s 24/7 manufacturing strains and supply important back up within the occasion of energy outages. The battery is predicted to offer between eight to 24 hours of backup energy, dependent upon the manufacturing facility’s load necessities. If the facility outage lasts even longer, the system additionally features a generator, giving Staar Surgical the flexibility to take care of manufacturing.
To ensure seamless operation, ReVamp Vitality designed custom-made switchgear that can mechanically swap the location’s vitality provide to back-up energy within the occasion of an influence outage. The microgrid is manageable through the SolarEdge monitoring platform. This can allow Staar Surgical and ReVamp Vitality to trace quite a lot of key parameters akin to photo voltaic vitality manufacturing, consumption, and battery vitality ranges in real-time and from a single platform.
“We’ve labored with Staar Surgical on several photo voltaic installations and for everyone we’ve got used SolarEdge know-how — it’s a key element of realizing the consumer’s requirement for prime vitality manufacturing, reliability, and clever management,” Slicing stated. “This begins with using Energy Optimizers to drag extra energy from the photo voltaic arrays and extends to the era of highly-granular efficiency knowledge that can allow us to function and preserve not simply the photo voltaic setup, however all the microgrid, in essentially the most environment-friendly and cost-effective manner potential.”
