Latest good review thumbs up

Larry Smith | Cookeville, Tennessee | 01/18/2024

Initially we chose another company. After some investigation indicated serious problems with that company, litigation was needed to be released from that contract. Lightwave Solar was highly recommended, and we found that they merit their reputation. Our installation has performed very well. With the tax credit we have planned for an additional battery to be installed.

Latest bad review thumbs down

Hattrick926 | Knoxville, Tennessee | 09/14/2017

Waiting too long

After waiting 3 months for the solar panels to be installed, we were told it would take no more than 10 business days to turn the panels on. It has been 12 business days and we don't even have the appointment with the inspector scheduled and after that there is another appointment that needs to be made with the power company before the panels can be turned on. Our first payment was made in early June. It's September and we have paid $30000 and have no idea when we will have solar power.

Reply from LightWave Solar: Our normal time frame for a solar project to be completed, from the point of initial contract, is 3-4 months, and this time frame is clearly stated on our proposal materials. We are constantly striving to improve this time frame, but there are a number of steps in the process that are out of our direct control, such as utility review and approval, local electrical inspection, and utility commissioning.<br /><br />We are happy that your project passed inspection today, and we look forward having it commissioned with your local utility as soon as is possible.

LightWave was very responsive

Operations Coordinator and technical consultant was very responsive. Some minor problems with installation. We are very remote and being 3 hrs out LightWave corrected the problem immediately. System has been up and running for approx 4 months. I also contacted their Marketing Manager Grace with insight to their portal for monitoring my system online and she was very helpful. I would recommend LightWave to anyone looking for Solar capabilities. Jim Jamestown TN

Wonderful Experience | Jackson, Tennessee | 02/14/2021

Wonderful Experience

We interviewed a number of installers and Light wave Solar was the most professional. The owner came out and did a drone overview of my home and selected the best location. The team was very professional and overcame every hurdle as it came along. We installed 10.2 KW and 2 Tesla power walls. Great system, our first neighborhood power outage, the system kicked in with out a flicker, every one in the neighborhood was out of power but us!. The Storm watch feature is great, once there is a Storm watch the batteries fill up from the grid and hold it in case it is needed. Really enjoy the Tesla App.

Truly Exceptional Experience

Having had a terrible experience with my initial "certified" installer who failed to complete the installation per contract and made several errors followed by a second installer who kept changing the start date for almost a year, I was fortunate to learn about LightWave from a friend who had used them several years ago. Other references were good. LightWave identified the errors by the prior installer, designed the resolutions, and completed the proper installation within their estimate despite a few surprises along the way and ON TIME. All individuals we dealt with from office staff to installation and commissioning were professional in every regard. I could not be happier with the result. Even the state electrical inspector and local power company representatives who were on site for commissioning volunteered very positive comments regarding the installation and readiness of all aspects of the system. An exceptional company in my experience that I highly recommend!

From Sales Reps, to Installers, to the CEO, Great People All.

I have used Lightwave Solar for two projects at my home. In 2012 they installed a 4.3 KW solar system and in 2019 they installed a 5.9 KW storage system. Since commissioning in April I have had a total of $59 in electric charges. As I recall all of the things regarding the last installation the one thing I remember most vividly was at the end an NES Supervisor coming over to me and remarking "congratulations". I think this speaks for itself why Lightwave Solar should be the solar company of choice for your solar application and installation.

new solar installation

The Lightwave Solar team was amazing, fast, and reliable. First, they used an electronic devise (fish eye) to assess the best position for the solar panels on our roof that is partially shaded by large trees. This devise can calculate the amount of sunlight on a particular spot over the different seasons of the year. The panel connectivity, function of optimizers and inverter module were explained in detail. After the contract was signed, a crew came a week later to install the system and integrate our 5 older solar panels. Remarkably, one of the workers found a squirrel nest under one of them and because the mother ran off into our woods, took the three tiny babies home and nourished them until they could survive on their own. The Lightwave Solar office helped to speed up the testing and contract signature by NES as well as the System acceptance by TVA (which usually takes quite a while). This team interacted extremely efficiently and professionally with me as customer. new

Newport Farm goes Solar

The Light Wave team came to our farm, did an assessment of our building, made the estimate and explained in detail the incremental steps of the process with the local power company. I was told that TVA would be communicating with me directly and all I needed to do was to forward all of those communications to Light Wave and they would take care of everything. I was pleasantly surprised when that was exactly what happened. The Light Wave install team showed up one day to do the installation and were finished the next day. About a week later the Light Wave team came back with the power company representative and commissioned the new system. Light Wave Solar did everything they said they would be doing and all I had to do was write a check. No more electric bill! It has been a pleasure to work with them.

residential customer

The company did a great job in installation and explaining how the system works. In 3 weeks I was able to get credit for over 55 dollars on the bill in November 2018. I have been able to keep up with my daily KWH. I encourage every one to look into using solar power toto help reduce the effects of CO2 emissions.

Residential Solar System

Great solar system. I wanted to wait a few months to make this review. I am enjoying the savings. After two months, I don't have an electric bill, even with the hot, hot days of summer. I actually look forward to seeing the electric bill arrive in the mail with a negative balance. Great job.

Top Quality

We've had our solar installed in Oct, 2013 by Lightwave Solar, and their knowledge and professionalism was beyond compare. We first called a local solar company in Bowling Green, and they wouldn't come out to measure. Their reason was that they didn't have any openings for a TVA spot, their loss!!! Lightwave came out the next day and checked exposure, and measured, then sent a quote 2 days later. We've now had our solar for almost 5 years now and we love it, just wish we would have put up more panels!!! Our last electric bill (May,2018 which was the 2nd. Hottest on record in Bowling Green) was $ 10.33. Can't say enough about Lightwave Solar<br />Dirk and Lorie Hallowell<br />Bowling Green,Kentucky.
