Since July 2016, Vector Structural Engineering has issued over 20,000 Structural Certification Letters to solar installers, becoming a solar industry leader virtually overnight. With over 60 professionals on staff and offices in three states, 15-year-old Vector Structural Engineering is an emerging player across the structural engineering field. According to Vector Founder and Principal, Roger T. Alworth, P.E., it was a strict adherence to process-based systems and excellent customer service that allowed the company to jump to over 1,500 Structural Certification Letters per month in less than one year. – Chris Crowell,  SOLAR BUILDER
