Staar Surgical (NASDAQ: SAAA) is a number one producer of implantable lenses utilized in ophthalmic surgical procedure has determined to energy its manufacturing plant with photo voltaic vitality. It has inaugurated a 1.1MW grid-tied microgrid on its manufacturing facility in Lake Forest, California.
Now operational, the system was put in to fulfill three essential targets: scale back vitality prices, enhance sustainability, and, most significantly of all, safeguard manufacturing within the occasion of grid outages attributable to excessive climate occasions.
The microgrid is powered by a 780kW SolarEdge DC-optimized inverter photo voltaic system positioned on the power’s roof and two newly-constructed carports. The 1752-module system is predicted to chop Staar Surgical’s vitality prices by roughly 50%, representing an annual saving of round $325,000.
However, this determine could possibly be a drop within the ocean in comparison with the financial savings that would doubtlessly be achieved by stopping spoiled manufacturing runs.
Jay Cutting, Snr., President of constructing and photo voltaic contractor, ReVamp Energy, which designed, put in and can keep the microgrid, explains: “Manufacturing contact lenses is a extremely energy-intensive course of that requires every lens to be heated in an industrial kiln repeatedly for a number of days.

“Any discount in energy of various seconds has the potential to spoil a complete 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 deal with the mission-critical problem of figuring out a cheap and sustainable technique to safeguard manufacturing.”
Excess photo voltaic vitality produced throughout the day will probably be saved in a 450kW battery to energy the positioning’s 24/7 manufacturing traces and supply important backup within the occasion of energy outages. The battery is predicted to supply between eight and 24 hours of back-up energy, dependent upon the manufacturing facility’s load necessities. In the uncommon occasion that an outage lasts even longer, the system additionally features a generator, giving Staar Surgical the power to take care of manufacturing.
Estee Lauder went solar in 2020 as a way to create a zero emissions provide chain.
To guarantee seamless operation, ReVamp Energy designed custom-made switchgear that may mechanically change the positioning’s vitality provide to back-up energy within the occasion of an influence outage. For added comfort, the microgrid is manageable by way of the SolarEdge monitoring platform. This will allow Staar Surgical and ReVamp Energy to trace quite a lot of key parameters corresponding to photo voltaic vitality manufacturing, consumption and battery vitality ranges in real-time and from a single platform.
Cutting, Snr. feedback: “We have labored with Staar Surgical on a number of photo voltaic installations and for each we have now used SolarEdge expertise – it’s a key element of realising the shopper’s requirement for top vitality manufacturing, reliability, and clever management.
“This begins with the usage of Power Optimizers to tug extra energy from the photo voltaic arrays, and extends by way of to the technology of highly-granular efficiency knowledge that may allow us to function and keep not simply the photo voltaic set up, however your entire microgrid, in essentially the most environment friendly and cost-effective method attainable.”
