  • ITC

    Federal Solar Tax Credit

    The ITC is a driving force behind increased solar adoption in the United States. Since its implementation in 2006, solar installation has grown by over 1600% with an average annual growth rate of 76%.

    The tax credit is available for purchased solar systems and is worth 26% of the cost of the system, which is paid back to the homeowner and determined by the amount of the individual’s taxable income that year.

  • Net Metering

    Bidirectional Metering

    Net metering is a utility billing system that will credit homeowners for any excess electricity that their solar system produces. The excess power is sent back into the grid for community use through a bidirectional meter. The credits provided are meant to supplement the homeowner’s energy use at night or when it’s cloudy when the system isn’t producing as much.

  • Solar Panel Tax Credits

    Solar Renewable Energy Certificate

    The state of Illinois offers a 25% tax credit of the total cost of your solar system, worth up to $35,000 (or $3,500 per year for up to 10 years). This is an added savings benefit to accompany the federal tax credit that has helped motivate the solar boom since 2006.

  • Utility Incentives

    Rebates with Duke & Santee Cooper

    You may be eligible to receive additional rebates to help cover the cost of purchasing your solar system, or earn payments for every kilowatt-hour (kWh) of electricity the panels generate.

    Duke Energy Progress is offering its customers a $1.00 rebate for every watt of solar they install with no limitation. Customers of Santee Cooper are eligible for rebates worth $1.30 per watt that is installed, up to $5,200.

The Benefits of Going Solar

Produce your own clean energy and help save the environment. Solar energy is a great alternative for anyone who values independence and efficiency. Start using flexible, lightweight solar now.

  • Shrink Your Carbon Footprint

    As one of the cheapest forms of electricity across the United States, solar dramatically reduces greenhouse gas emissions and is proven to help slow climate change.

    According to the EPA, an average 8.6kW home solar system takes 9,606 pounds of CO2 out of the air each year. That's the same as 50 trees.

  • Combat Unpredictable Utility Rates

    The Energy Information Administration ( reports that utility rates are rising year over year. Suntuity Solar provides price protection throughout the length of your agreement, so you know what you’ll be paying today, tomorrow, and for the next two decades. Enjoy peace of mind in knowing your rates will never spike – it’s more valuable than you may realize.

  • Tax Credit Incentives for Purchasing Solar

    Purchasing your home solar system allows you to take advantage of the Solar Investment Tax Credit (ITC). Solar power system owners are eligible for this tax credit which is worth 30% of the total cost of the system through the end of 2022. After 2022, the percentage will decrease each year and then expire completely for residential solar systems purchased after 2023.
