  • Tennessee Valley Solar Calculator

    Considering Solar? This tool can help you make an informed decision when considering whether or not to install a small-scale solar system. The solar calculator is intended to be used by residential and small business customers who want information on the true cost and payback of installing solar in the Valley.


    * Estimates based on current rate structure, which is subject to change. System size and total generation is based on selected inputs; however the generation used could be significantly lower due to the timing differences between generation and energy use.

  • 2021 BBB Tax Framework: Renewables Incentives


    • UPDATED: Tax incentive extensions and modifications (Total for entire subtitle: $325.281 billion over 2022-31, increased from $273.456 billion in September).
    • November 19th, 2021: The House of Representatives passed the Build Back Better Act, which includes a 10-year extension of the solar Investment Tax Credit (ITC), strong support for domestic solar manufacturing and other critical policies to advance American clean energy deployment and production.
    • Investments and Incentives for Clean Energy Technology, Manufacturing, and Supply Chains ($110 billion): Targeted incentives to spur new domestic supply chains and technologies, like solar, batteries, and advanced materials, while boosting the competitiveness of existing industries, like steel, cement, and aluminum.
    • In addition to allowing taxpayers to elect to claim the PTC for solar energy facilities, the ITC for solar energy property would be extended, providing a base credit rate of 6% and a bonus credit rate of 30% through the end of 2026.
  • 30% by 2030: A New Target for the Solar+ Decade

    Details from the SEIA's 30 by 30 Report

    Reaching 30% by 2030

    To reach 30% of generation and stay on track to decarbonize the electricity grid, average solar installations must increase from roughly 30 GWdc over the next decade to more than 48 GWdc

    MASSIVE Deployment Needed

    Over the 9-year period between 2022 – 2030, total solar installations must increase by nearly 130% beyond the baseline forecast from the most recent U.S. Solar Market Insight report.


    To reach 30% of all electricity generation, the solar and storage industries would need to hire 800,000 new workers to reach a total workforce of more than 1 million Americans. Along the way, the industry would invest more than $820 billion into the U.S. economy.

    SEIA Statement

    “Solar is a job-creator, and the long-term tax incentives for solar, storage and domestic manufacturing will put us on a path to decarbonize the electric grid, reach the President’s 2035 clean energy target, and create hundreds of thousands of quality career opportunities in every community."
