Knoxville Solar Installer

LightWave Solar is proud to serve the Knoxville, TN area and the surrounding regions.

If you are looking for residential, commercial, or municipal solar design consultation and installation, then we would love to partner with you. In our modern day world, solar power has become increasingly available and affordable. Currently, there are many benefits to going solar, whether it is for your home or business.

Residential Benefits include:

A 30% federal tax credit for systems installed before the end of 2019. This credit is equal to 30% of the total cost of the system, and gets applied against your income tax liability for the year the system is installed, or it can also be claimed for the previous tax year, or carried forward.

As part of the Green Power Providers program provided by TVA for grid-tied solar systems, TVA buys 100% of your solar generation at the escalating retail rate. As rates increase, so do your solar payments. Credits then roll over month to month, and if there is an accumulation of unused credit, your local utility place will send you a check after 12 months.

On top of these benefits, going solar increases the value of your property and helps in differentiating your home from others on the market. Clearly, going solar can be a great investment for homeowners.

How do businesses benefit?

At LightWave Solar, we are committed to helping you determine if solar is a valuable investment for your business. Many business owners invest in solar systems because of the financial return, and because they feel it is the right thing to do as an ethical company. We will help walk you through how the tax and utility incentives work, as well as discuss the financing option that allows your business to be cash flow positive in less than two years. Many of our business owner clients have seen a one year payback on their systems.

What about Nonprofit organizations?

Nonprofit organizations are making the world a brighter place, and can make it even brighter by choosing to go solar. Nonprofits can get their own solar system for long-term energy savings or use the support of sponsors or investors who will be able to claim the federal tax incentives for solar systems. A way this can be done is by having the investor lease a nonprofit’s rooftop or property, own the system for a period of time, and ultimately earn most or all of the revenue generated during that time. Then, the nonprofit can either buy the system or the investor can donate it. Whether the nonprofit organization owns the system or simply provides a rooftop, going solar can provide educational and awareness opportunities for the nonprofit.

Can government buildings reap solar benefits too?

Many local, state and federal governments are in a great place to take advantage of solar energy systems because of the unique combination of building ownership, long-term financial outlook, and superior credit ratings. A rising number of government agencies are changing over to solar to help against rising energy rates, because of the unique ability of solar systems to provide predictable energy savings for decades.

So you’re interested in going solar. What’s next?

To begin, contact us to get your free preliminary estimate which will show five core pieces of your system’s information: project size, system output, project cost, incentives overview, and site drawing. We will also review your financing options. If the preliminary estimate works for you, we will schedule and make a site visit to confirm any measurements. Once this data has been verified, we will create a proposal with the specific system output, existing warranties, incentives, and firm contract price. Once the contract is signed, and the first deposit for permitting and equipment is provided, our in-house design team will submit the TVA paperwork, obtain the necessary permits, and design the most efficient solar system for your place. Then our project management team will reach out to you to schedule a time frame to build and install your solar system, meticulously coordinating all of the necessary inspections and commissioning. Ready to get started, or want some more information? Contact us at 877-748-1260, or you can also email us at

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.
