Questions for a Solar Contractor

1. Is the contractor a full-time solar installer exclusively focused on solar PV?

LightWave Solar holds an unlimited electrical contractors license in the states of TN, MS, AR and AL. We are 100% focused on turn-key solar PV design and installation with over 30 full‐time employees.

 

2. What is included in the contract amount?

LightWave Solar provides turn-key design and installation. This includes:

  • Site evaluation to verify system design requirements
  • Electrical drawings and site plans by in-house engineers
  • Completion of interconnection application and all other paperwork required by local utility
  • Permitting
  • Equipment procurement (panels, inverters, disconnects, meter, conduit, wire, etc. – everything needed for fully functional system)
  • Installation and inspections
  • Grid-interconnection/commissioning with local utility
  • One-year workmanship warranty

 

3. Is your solar contract a fixed-price contract or an estimate?

LightWave Solar provides an accurate, fixed contract amount that is based on years of experience and site-specific information. You will not be surprised with added costs.

 

4. How many years has the contractor been installing solar PV?

LightWave Solar has been installing solar PV full-time since July 2006. We helped pioneer the region’s solar industry.

 

5. How many solar PV projects has the contractor installed?

LightWave Solar has designed and installed over 800 solar PV systems throughout the Midsouth, primarily in Tennessee, Kentucky and Mississippi. Our projects include large systems (200kW-5MW), systems for small businesses ranging from 20-100kW, and over 400 residential systems ranging from 2kW to 50kW. We have installed nearly one fourth of the total number of solar systems in the TVA region. In addition, LightWave Solar is responsible for the design and installation of the first solar interconnections with over 45 electrical utilities in the TVA region. Our experience sets us apart from other contractors in the area.

 

6. Have you talked to any of the contractor’s customers?

LightWave Solar has hundreds of happy solar customers and many repeat customers. Please ask us for our customer references and contact them for their feedback. You can read our online customer reviews at these links:

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 10% down payment upon contract signing. Shortly thereafter, we require a 65% 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 Solar Pathfinder or 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 six fully-certified NABCEP Solar PV Professionals on staff. 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 serves on the Policy Board. TenneSEIA represents and advocates for the solar industry in Tennessee, and membership shows a commitment to the industry.

The entire team at LightWave Solar went above and beyond to ensure that our solar install was done on time, on budget, and to our satisfaction. Professional in every way. I can't get over how seamlessly they have integrated everything to our 1960 built home. Very well done. An added bonus is their handling of the necessary licenses, myriad forms and paperwork and approvals from local power company and TVA. These guys deserve 10 stars!

We installed a 10 KW solar panel array on the roof of our home this past fall. The process required coordination between us (the customer), the local electric company (Nashville Electric Service) and the Tennessee Valley Authority (TVA). While this may seem daunting, it turns out that apart from signing a few routine documents, the process requires little to no effort on the part of the customer: Lightwave Solar takes care of all the details. Their attention to those details was impressive, which meant the whole operation was smooth, professional and basically worry free. The physical installation itself is a marvel of craftsmanship and technology. Lightwave Solar fully earns their five star rating and I recommend them without reservation.

My first month's savings was over $100. This is in spite of shorter fall days, cloudy days, and rain. The shortest day of the year is in late December. Its best performance will be in the spring and summer. I am very pleased with it.
