Financial Incentives

Logo IRS

The IRS offers two tax incentives for commercial and industrial solar projects. Taken together, they can reduce solar project costs by about 45% within the first year!

26% Federal Investment Tax Credit (ITC) is available for commercial solar systems under construction by 12/31/20. To be considered “under construction” in 2020, the project can have started physical work or have incurred at least 5 percent of the total cost. The tax credit amount is uncapped and equal to 26% of total solar project cost. For projects started in 2021, the tax credit drops to 22%.

Modified Accelerated Cost Recovery System (MACRS) is a method of depreciation in which a business’s investments in solar property can be recovered through tax deductions. MACRS benefits can be taken all in the first year of system operation and equal up to 20% of total solar project cost.


USDA Rural Energy for America Program (REAP) Grant covers up to 25% of total solar system cost for agricultural producers located in any area and small businesses located in rural areas.

  • The next grant application deadline is March 31, 2020.

  • LightWave Solar assembles the application for you.

  • Our grant approval track record is 96%!

  • Please contact us for eligibility details.

Our Process

  • Contact us for your project consultation. Then, we can provide a preliminary proposal which includes your estimated total project cost, federal tax benefits, estimated energy savings, environmental benefits & a project sketch. We will also review your financing options.
  • If your preliminary proposal looks acceptable, we will schedule and complete a site visit to confirm our measurements.
  • Once we have verified site details, we will present your formal proposal with system output, warranties, incentives and firm contract price.
  • Once you sign your contract and provide your first deposit for permitting and equipment, our in-house design team submits utility paperwork, obtains necessary permits and designs the most efficient solar PV system.
  • Our project management team will reach out to you to schedule a timeframe to install your solar system, coordinating all required inspections and commissioning.

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 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.
