LightWave Solar is the most experienced
Tesla Powerwall Certified Installer in our region.
Let’s talk about how you can achieve grid independence.

Tesla Powerwall uses advanced lithium-ion battery technology
for a sleek, innovative and completely automated system
requiring almost no maintenance.

Solar Self-Consumption icon

Reduce your reliance on the grid. With a solar and Tesla Powerwall system, you can power your home with solar energy during the day, and store extra solar energy for nighttime use. Powerwall allows your home to run on clean solar energy even after sundown.

Back Up icon

Have power during a grid outage. When the grid goes down, Powerwall keeps on the lights, and you can use your appliances, devices, and charge your electric car. As long as the sun comes up, you’ll have more power every day.

Always Connected icon

Get insight into your home’s energy use and take control. You’ll love Tesla’s mobile app. It shows real-time and historic energy consumption, solar generation and battery status. And, if a storm is predicted, Powerwall settings will adjust to ensure a full charge in case of a grid outage.

Lightwave Solar installed a 10 kw system on my building in Lebanon. The installation crew was very professional and completed the install in a morning. Lightwave handled all the permitting and negotiations with TVA/MTEMC. I now have an app on my phone that tells me how much power my panels are generating since they were installed.

The folks at LightWave Solar are awesome. They were patient and very responsive to my long list of questions prior to signing the contract. After signing the contract, they kept me updated on progress and walked me through steps that required my input on the permitting process. They made me aware of the current step and the next step so I knew what to expect. The installation crew was knowledgeable, efficient, friendly, and went overboard to make sure the installation met my needs. The accounting folks were also great to interact with. Every aspect of my solar purchase went smoothly thanks to the great people at LightWave....from the initial sales, business office, and installation crews--all of them make customer service a PRIORITY.

We had a great experience with Lightwave. They installed an add on system of 5kW along with a Tesla Powerwall battery. From the initial presentation to the final project completion, they all worked together and everyone on their team seemed truly happy to be engaged in this new industry. They are true professionals and I was glad we selected them. In addition to having a high tech back up system for my home, I am now off grid about 30% of the time. Amazing.

I needed LightWave's help after a wind storm caused a tree to fall on my house. The tree destroyed ten solar panels on my roof. LightWave's technicians visited me to assess the damage and plan repairs. LightWave's project manager took over from that point. After the design was complete and approved, the installation crew completed the job in a single day. Every LightWave representative was pleasant and professional. I would recommend them to anyone who needs their services.

The whole team at LightWave Solar did an all-around excellent job! They showed up on time as expected and communicated everything very clearly on what I can expect to see and happen. They were all very professional and courteous throughout the entire process. I am already seeing MUCH lower electric bills. Thanks again to everyone at LightWave Solar, I greatly appreciated your services.

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.

The Lightwave Solar team was easy to work with, responsive and reliable. They considered several alternative layouts before settling on the best configuration for our situation. We are please to have 10 KW of solar panels, which covers most and at times, all, our energy usage for a month. Thanks!

The process to get started is the most involved but once the installation is approved by your local power company, you're ready to go. It took about a month from approval to turning the system on. There were hiccups but the team at LightWave handled them all quickly and professionally. Everyone who came to our home for installation and commissioning was extremely professional and neat. The jobsite was cleaned up each day which I appreciated. They also gave us an estimate of solar generation based on month and for the first month they were spot on! I would highly recommend if you're looking for a solar system to consider this company.

Early in 2016 our family broke ground in building our new home. We knew we wanted solar and we had reached out to the companies in the area and selected Lightwave solar. From the beginning, they made it as easy as turning the key. From applications for the solar program all the way to getting things secured with our future electric company. After moving into our home, the installers were out and finalized our system bringing everything online. Our first full month of November we received our first bill. Two electric cars, entertaining during the holidays and getting a new home set up meant we'd used a good bit of electricity. $17 Dollars...the utility company had as a credit! This was amazing. This was an amazing investment and an equally awesome experience.If you are looking to learn more about solar, you must reach out to Lightwave Solar.

Solar panels area wonderful thing, They sit in the sun and convert sun light into useable electricity with virtually no maintenance, fuel or up keep. The initial cost is a little pricey, but the government will give reimburse a buyer 30% in the form of a tax credit, not a deduction a credit. As an up-side, if one invest the cost of the system into say a tax free muni-bond, he would have to earn better than 3% to beat it at the current cost of electricity, which is going to get better as the price of electricity rises in coming years. A second up-side is the knowledge that the solar energy produced contributes nothing to pollution and used no natural resources.My daughter did the research. SunPower panels are the best. LightWave Solar is their local dealer dealer here in the Nashville area. I called them. They came out recommended an appropriate system. I said do it and they did. They took care of everything, building permits, sell back agreements, engineering, installation, everything. They did what they said they would do in the time frame they predicted for the price quoted. I could not be happier with the system, price or service. SunPower panels, LightWave Solar. Do it.

They say it starts at the the top and thanks to Steve Johnson, Lightwave Solar's owner, it appears that everyone in his company understands what it takes to work at a very high level of professionalism and expertise.Every member of the Lightwave team made the process of adding on to our existing solar array, easy. Pre-install was completely without issue. They evaluated my needs, then worked with the TVA to determine the maximum system size, filed the proper forms, obtained permits, coordinated with my local utility company, and answered all my questions. They completed this part of the process early and were prepared to start my install two weeks earlier than they originally scheduled.The install crew was friendly, professional, neat and worked well with each other. In addition to tying the new panels into my existing solar system, they also tied everything together to work with my whole house, 36kW propane generator - a fairly complex process.When the install was complete, they took the time to explain how everything worked and showed me how I could access all of my solar generation statistics online.It’s rare that I feel comfortable recommending an organization without reservation, but in this instance, I can say that after three months, everything is running perfectly and I’m still very happy with every aspect of the job.

I loved my experience with LightWave Solar! From the get go they were very professional and easy to work with. Getting solar panels on my house was a bit of a process with obtaining proper agreements and permits with utilities etc, but they handled every step-from sales through installation. I was impressed by the technology they use to project over the course of the year how much sun will hit each part of the roof to help decide if and where to get panels. They also have different financial options and help navigate what's best investment for you. And there are currently major tax benefits! Feels like a smart investment mixed with a really great feeling, knowing that the power I use in my house (and to charge my electric car) are from the sun. It's pretty amazing to get my utility bill now, and depending on the month, it is either a very very small amount or they pay me. Going solar has been a great experience and I can't recommend LightWave enough for helping me to do that!

I was very impressed by the professional quality of the work performed by the LightWave Solar installer. Though there was a large capital payment required for my 28 solar panels, they're already (slowly) reimbursing me by paying 70% of my monthly electric bill.
