In 2012, Caleb Arthur had a vision that solar energy could thrive in the Midwest. He founded Sun Solar in Houston, Missouri, and by 2016 relocated the company’s headquarters to Springfield, where it has grown into one of the region’s most active solar installers. What started as a one-person operation has expanded to a team of over 100 employees completing thousands of solar installations across Missouri, Kansas, and Illinois. The company has earned recognition from Solar Power World magazine as a Top 400 Contractor nationally and was named the #1 residential solar installer in Missouri. Sun Solar has also been recognized by the Springfield Business Journal as the fastest growing business in the city. The company distinguishes itself through a philosophy of ‘reduce before you produce.’ Before designing a solar installation, Sun Solar evaluates homes and businesses for energy efficiency opportunities through its Smart Energy Solutions division. This comprehensive approach helps Springfield homeowners and businesses across the region maximize their savings while minimizing their environmental impact. Sun Solar handles every phase of a project in-house, from initial energy audits and system design to permitting, installation, and activation. The company has installed solar panels on everything from standard residential rooftops to custom projects including a solar canopy designed as a pickleball court and Missouri’s first Tesla Solar Roof installation. Sun Solar partners with Old Missouri Bank in Springfield to offer in-house financing options, and the company is among the first in the world certified to install Tesla inverters and Powerwall battery systems. With rising utility rates across Missouri—including recent increases exceeding 40% from some cooperatives—Sun Solar focuses on delivering predictable energy costs to homeowners tired of unpredictable electric bills. The company maintains locations in Springfield and Houston, Missouri, with additional offices in Kansas City and Illinois, allowing it to serve the southern half of Illinois and eastern Kansas. As a BBB-accredited business with an A+ rating since 2013, Sun Solar continues to expand its reach while maintaining its commitment to making solar energy accessible and affordable throughout the Midwest.
