Lightwave Solar Electric

LightWave Solar entered our Tennessee evaluation as the state's most established residential solar specialist, and what our research team found largely confirmed that reputation. Founded in 2006 and headquartered at 3026 Owen Drive in Antioch, just south of Nashville, the company has spent close to two decades focused almost exclusively on photovoltaic design and installation rather than treating solar as a side line off of an electrical or roofing business. Per their own published figures, they have completed more than 1,400 solar PV systems across the Tennessee Valley, representing roughly 80 megawatts of installed capacity, and they employ a team of more than 70 full-time staff with multiple NABCEP-certified PV installation professionals on the roster.

What stood out to our researchers is the depth of credentialing behind the day-to-day work. NABCEP certification, which the industry treats as the gold standard for solar professionals, is held across multiple roles on the LightWave team rather than sitting with a single individual. The company holds Tennessee Unlimited Electrical Contractor License No. 58005 and 71602, carries an A+ rating with the Better Business Bureau, and posts a 4.88-out-of-5 average across 51 verified reviews on SolarReviews, with similarly strong scores on Google. As a founding member of the Amicus Solar Cooperative, LightWave participates in a national purchasing and best-practices network that includes more than 70 independent installers, and President Chris Koczaja sits on the cooperative's board.

On equipment, LightWave describes itself as brand-agnostic and has installed systems from REC, Q Cells, Silfab, Mission Solar, and Panasonic-class panels paired with SolarEdge, Enphase, SMA, and Fronius inverter platforms, alongside Tesla Powerwall and Enphase battery storage. They offer ground-mount, roof-mount, carport, EV charging, and smart-panel work, and they self-perform service and monitoring rather than handing customers off after commissioning. The most common knock our team found in customer feedback was occasional delays between contract signing and system activation, a familiar pain point in the post-2024 interconnection environment that prospective customers should ask about during the sales process.

With a composite score of 86.4 out of 100, LightWave Solar stands as our top-ranked solar company in Tennessee for 2026.
