5. How many solar PV projects has the contractor installed?
LightWave Solar has designed and installed over 850 solar PV systems throughout the Midsouth, primarily in Tennessee, Kentucky and Mississippi. Our projects include large commerical systems (200kW-5MW), mid-size systems (20-100kW), and over 500 residential systems ranging from 2kW to 50kW.

7. When and how are payments made to the contractor? Do they get paid before commissioning?
LightWave Solar outlines the payment schedule before we ask you to sign a contract. Typically, we require a 25% down payment upon contract signing. Shortly thereafter, we require a 50% payment to order materials. Once the system has been installed and commissioned by the local utility, we invoice for the remaining 25%.
8. How did the contractor calculate production? Can it be verified by a reputable third party?
LightWave Solar understands that solar customers are buying production, not system size. Thus, we recommend high-performing solar panels and accurately estimate kilowatt-hour production over time. We use several production estimators including PV Watts, PV Syst, and PV Sol. Our production estimates account for shading if applicable (using Solmetric SunEye), orientation, and pitch. Our estimates can be verified on-line at the National Renewable Energy Laboratories (NREL) site.
9. Does the contractor have Full NABCEP-certified Solar PV Installers on staff?
LightWave Solar has 9 fully-certified NABCEP Solar PV Professionals on staff, more than any other company in the Southeast. NABCEP stands for the North American Board of Certified Energy Practitioners, and it is the gold standard for solar PV certification. The full NABCEP certificate is earned after passing a rigorous exam covering design, installation and codes, as well as meeting experience and training requirements. Conversely, NABCEP’s entry-level certificate requires no installation experience.
10. Is the contractor a member of TenneSEIA?
LightWave Solar is a Charter member of the Tennessee Solar Energy Industries Association (TenneSEIA), and LightWave Solar’s President and CEO, Chris Koczaja, serves as President of TenneSEIA.
