Sunfig was originally founded to enable interested parties to design and to build solar projects to realize their maximum potential. It had been the experience of the founders that "Rules of Thumb" were too often being used to define these complex systems - "leaving money on the table and carbon in the air". A web-based platform that gives the User the capability intelligently to iterate through viable project configurations to maximize LCOE or IRR, the Sunfig Intelligent Feasibility Tool (SIFT) allows the User quickly to determine the optimum design for a particular project. Problem addressed: a particular site has usually an optimimum designbut with limited time, tools and data, Designer commit to a design strategy without undertaking that anlaysis . SIFT produces the data needed to be confident in design decisions and, by xtension, win more projects. SIFT Features: Projects up to 1GW: No software to install, SIFT runs from your browser: Import topography from USGS and Google: Run up to 1000 GCR and DC:AC configurations at once. Sunfig Performance Modeling comparable to PVSystem; COE and IRR lifetime financial modeling Import modules and inverters from PAN, OND, PVSystem; Import/Export KMZ; Export data direct to XLS and CAD; Ground Fixed Tilt and Single Axis Tracker; Runs typically take less than 1 minute to complete. In February 2021,it was announced that Gibraltar Industries (NASDAQ:Rock) - manufacturer of materials used in building construction - had acquired SunFig Corporation
