With our region still reeling from the ice of Winter Storm Fern, one company stands apart in delivering true resiliency solutions. This year, LightWave marks its 20th anniversary, a rare milestone in the distributed solar market and a testament to a business built on patience, integrity and long-term thinking. That mindset is designed into every home microgrid project, helping power hundreds of homes through days-long outages.
Headquartered in Tennessee and deeply rooted in Williamson County, LightWave Solar has quietly earned a reputation as the trusted partner behind some of the region’s most thoughtful and forward-looking energy projects. At the center of that story is CEO Chris Koczaja, whose journey to renewable energy began far from rooftop panels and battery storage systems.
Before solar, Chris spent his early career with a large heavy equipment manufacturer, working in power generation with large diesel and natural gas generators including projects that converted landfill gas to electricity. His work also took him into a biodiesel pilot program and deep into coal mines through the company’s mining division. It was heavy industry, complex, powerful and rooted
in the traditional energy economy.
That perspective shifted when a former dealer called Chris with an opportunity to help start a biomass energy company. He became employee number two, spending seven years immersed in biomass and waste-to-energy projects. It was during this time that a defining realization emerged. At one facility, Chris watched the construction of a waste-to-energy plant with more than 100 single points of failure alongside a solar array being installed on the same site by the customer.
“The contrast was striking,” he recalls. “The complexity versus simplicity.”
That simplicity and reliability planted a seed. When LightWave’s founder Steve Johnson began looking to sell the company in 2017, Chris was looking for something different. In May of that year, he joined LightWave as majority owner, stepping into a company poised for growth at what he describes as a “tipping point” for solar energy.
That same year, LightWave completed its first “behind-the-meter” 200-kilowatt commercial project that required no utility incentives. It was a clear signal that solar had matured from niche to viable and that LightWave was ready for its next chapter.
From the beginning, LightWave has distinguished itself not by selling solar and energy storage projects at all costs, but by insisting on doing it right. The company’s guiding principle, “Experience. Quality. Passion”, is more than a tagline. It’s a filter through which every project is evaluated.
If a roof isn’t suitable, if the payback doesn’t make sense or if the system won’t meet resiliency standards, LightWave will advise against moving forward. That commitment to integrity has shaped the company’s reputation and its unusually long sales cycle. It’s not uncommon for clients to return two or even three years after an initial consultation, ready to proceed when the timing is right.
One story Chris often shares involves the founder advising a potential customer not to install solar because her husband wasn’t fully on board. The sale was paused, not because the system wouldn’t work technically, but because alignment mattered. For LightWave, trust and long-term relationships come first. That philosophy resonates strongly in Williamson County, where many residents are also business owners. While LightWave is well known for its residential work, a significant portion of its portfolio lies in commercial-scale projects, often discreet, sometimes confidential and occasionally for “really exclusive clients.” LightWave approaches solar and storage the way others approach roofing, electrical, or mechanical systems which are designed and built to last decades. For homeowners, this means LightWave takes equal care with both performance and aesthetics.
Systems are custom-engineered to complement the architecture, clean rooflines, concealed conduit, and HOA-sensitive designs. Detailed 3D renderings allow clients to see exactly how panels will look before installation, and whenever possible, panels are placed on the back of the home to preserve curb appeal. Every project begins with an extensive design phase, often lasting months, followed by installations scheduled four to six months from the initial inquiry.
Quality is non-negotiable. LightWave installs commercial-grade systems even on residential homes, with wiring enclosed in metal conduit for durability and a clean finish. For homeowners and business owners who value control and continuity, energy decisions today are less about sustainability and more about certainty. Increasingly, homeowners aren’t just asking for solar, they’re asking for storage. Most residential inquiries now include whole-home battery backup systems, driven by a desire for resilience during outages and greater control over energy
use.
That shift aligns with LightWave’s future vision. “We’re becoming a storage company that does solar,” Chris says. As electricity demands grow, driven in part by artificial intelligence and data-intensive technologies, grid reliability is becoming more uncertain. Storage, he believes, is the key to solving more of the utility’s challenges than solar alone.
At his own home, Chris retrofitted a fully automated microgrid system that can run off-grid indefinitely, often operating off-grid for weeks at a time, demonstrating the robustness of the system in a typical decades-old Wilco home not especially characterized for its energy efficiency. It was a resiliency hub throughout the storm providing a contingency plan for friends and neighbors. He describes operating the home as a game by optimizing energy use, managing loads and fine-tuning performance all through his phone. While most customers prefer automation without daily interaction, the technology offers flexibility for those who want deeper engagement, from controlling EV charging to heating and cooling schedules.
Long-term, Chris envisions a decentralized grid made up of interconnected microgrids that are more resilient, more efficient and better suited for the future. It’s a vision that many local utilities share as their dedicated teams work hard to deliver energy even when the weather and grid are at odds.
LightWave leverages partnerships with dozens of companies across the country through its membership in Amicus Solar Cooperative and has sister companies in Vermont and Arkansas. Despite this, LightWave remains proudly local. It’s a Tennessee company with deep community ties and a team committed to staying ahead of the curve without losing sight of its roots.
After 20 years, LightWave Solar’s success isn’t just about technology. It’s about people. Customers treated as partners, employees guided by values and leadership grounded in experience. In a rapidly evolving energy landscape, LightWave continues to prove that doing things the right way is not only possible, but powerful…even when the power is out.
