With more than 60 furnaces for vacuum heat treating and brazing services, ranging from lab-size research and development furnaces to the largest commercial vacuum furnace (48 feet long, 150,000-pound capacity), the site experiences very high energy demands and energy charges. The customer requested the largest solar system the building could handle. The solar installer, SunGreen Systems worked with its energy storage partner, Stem, to propose a combined solar and Tesla battery storage system to shave the demand and arbitrage energy. They chose S-5! products because the solar attachments provided design flexibility in attachment locations. In addition, the lightweight solution allowed them to avoid costly retrofits. During initial client meetings, SunGreen Systems demonstrated the reliable racking solution via a sample kit provided by S-5!―enabling the client to find the right clamp for the project and allowing them to see first-hand the factory-installed gaskets that would preserve the building’s integrity.
