Who is James Showalter?

James Showalter is the founder and CEO of Signature Solar and EG4 Electronics. He built both companies from the ground up in Sulphur Springs, Texas.

His path into solar power started with personal necessity rather than a business plan. Repeated hurricanes near his childhood home pushed him toward alternative energy at a young age.

That early interest eventually grew into a full-scale solar retail and manufacturing business. Signature Solar now serves customers across the United States through online sales and a physical retail store.

Showalter has also become a recognized voice in the solar and battery storage industry. In 2025, he was named an EY Entrepreneur Of The Year Southwest Award finalist.

Early Life of James Showalter

James Showalter grew up in Houston, Texas. His family experienced two major hurricanes that knocked out power in their area for extended periods.

By the time he turned 13, those storms had already shaped his interest in backup power systems. During Hurricane Ike in 2008, he and his brother John began researching solar technology out of boredom during the blackout.

That shared curiosity turned into a lasting partnership. The two brothers would later build their first whole house solar system together in 2012.

James Showalter Career

Showalter’s first steps into solar work came through hands-on installation. In 2015, he and his brother began installing solar systems for customers of their family fence-building business.

Building an Installation Business

Word of their solar work spread quickly across rural Texas. For four years, Showalter grew the installation side of the business while learning the local market firsthand.

That market came with real challenges, including low regional power costs and utility companies resistant to solar adoption. Even so, demand for backup power kept growing among customers.

Founding Signature Solar

In 2019, Showalter launched Signature Solar as an online store in Sulphur Springs, Texas. The company started with just six people and a simple goal of making solar products more affordable.

The business grew quickly by focusing on transparency and customer support. Signature Solar also became an early dealer-based training site for the North American Board of Certified Energy Practitioners.

Launching EG4 Electronics

Wanting to cut costs even further, Showalter and his brother moved into battery manufacturing. That decision led to the creation of the EG4 brand, focused on server rack batteries and energy storage.

EG4 Electronics has since expanded into inverters and mini split systems. The company has also formed supply partnerships, including work with LG on American-supplied battery cells.
