Residential Solar

Option 3: Live off-the-grid

Just a handful of our customers have off-grid solar systems.


Living off-the-grid usually requires minimal electricity use and daily energy management. This lifestyle entails planning and coordinating your energy use based on available sunlight and battery charge.


Those who live off-the-grid are their own utility, even in the middle of winter when sunlight is low and needs are high. A generator can provide backup power for your off-grid solar system.


We can help you explore this option if you think it is feasible for your site. We would begin the process with an upfront design fee. Also, we would ask you to complete our Load Calculation Worksheet.

An example of one of our off-grid projects:


4kW off-grid system for a cabin in rural Tennessee


8 AGM batteries


Generator for backup

Types of Installations


We will evaluate the suitability of your roof based on this criteria:

  • Faces south, east and/or west
  • Has minimal shade from nearby trees
  • Has minimal obstructions like chimneys,dormers,etc.
  • Is in good condition (typically, under 10 years old)
  • Is asphalt shingle, metal, standing seam, or another material suitable for solar panels

Examples of our roof-mounted projects

10kW solar system on an asphalt shingle roof in Brentwood, TN

10kW solar system on standing seam metal roof in Clarksville, TN

15kW solar system on standing seam metal roof in Memphis, TN

Other mounting options



A ground-mounted system costs more than a roof-mounted system, but provides higher production. Here’s why: We can install the panels so they are orientated due south, receiving the most sunlight. Also, ground-mounted solar panels receive more air flow, enhancing performance.

Examples of our ground-mounted projects

10kW system in Kingston Springs, TN

20kW system in Clarksville, TN

10kW system in Hendersonville, TN

Canopy or awning

Get the perks of a ground-mounted system, plus shade for your parking area, patio, or porch. A parking canopy pairs nicely with an electric vehicle (EV) charger. Cool factor: Translucent solar panels can be used!

Examples of our solar canopy and awning projects

5kW solar canopy in Brentwood, TN

5kW solar canopy in Nashville, TN

5kW solar awning in Nashville, TN


Solar-charged battery systems & all solar mounting types qualify for the 26% federal tax credit.

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.

Light Wave Solar is terrific. All their people were great to work with, knowledgeable and on- the- ball. They were everything i could have asked for and i couldn't be happier with the system they installed. So far it is working just as i hoped!

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.
