Benchmark Cost Analysis

Estimated Solar Panel Costs in Matthews (2026)

The cost of a solar installation depends on the size of the system needed to offset your electricity usage. Based on local energy needs and pricing, a typical system for a Matthews home breaks down as follows:

  • Solar-Only System (9.0 kW): An estimated gross cost of $22,500. This system is sized to cover the electricity needs of an average home in the area.
  • Solar + Battery System (9.0 kW solar with 10 kWh battery): An estimated gross cost of $37,500. Adding a battery provides backup power during outages and can unlock specific utility incentives designed to support grid stability.

These figures represent the total cost before any state or utility-level rebates are applied. The final price can vary based on your specific roof, equipment choices, and installer.

Incentives & Tax Credits

North Carolina Solar Incentives After the Federal Credit

While the 30% federal residential clean energy credit is no longer available for systems installed in 2026, North Carolina homeowners have access to powerful state and utility-level programs:

  • Duke Energy PowerPair™ Program: This is a key incentive for Duke Energy customers. It offers a significant rebate for installing solar and a battery together. The program can provide up to $3,600 for a 10 kW solar system and $4,000 for a 13.5 kWh battery, directly reducing the upfront cost and making the solar-plus-storage option much more attractive.
  • NC Property Tax Exemption: North Carolina law exempts 100% of the value added by a residential solar system from your property tax assessment. You get the benefit of a home improvement without the corresponding tax increase.
  • Battery Bill Credits: Some utility programs may offer ongoing bill credits for allowing the utility to draw from your battery during peak demand events, providing another stream of financial return.

An owned solar system can also be a compelling feature for potential buyers, potentially supporting your home's resale appeal down the road.

How Duke Energy Credits Your Excess Solar Power

Under Duke Energy's net metering and net billing structures, the rules for excess energy are critical. When your panels produce more electricity than your home is using, that surplus power is sent to the grid. The value you receive for that exported power can vary depending on the specific tariff you are on. For some customers, it may be a 1-to-1 credit, while newer plans may offer a lower credit value. This is why pairing solar with a battery is increasingly recommended. By storing your excess solar energy in a battery, you can use it yourself later in the evening, ensuring you get the full retail value from every kilowatt-hour you produce instead of selling it back for less.

Projected Savings

Projected Energy Bill Savings

A 9.0 kW solar system in Matthews can generate significant savings by offsetting electricity you would otherwise buy from Duke Energy at their current rate of around 13.9 cents per kWh.

With this setup, a homeowner could see estimated annual savings of $1,432. Over the life of the system, this adds up. The estimated payback period for a solar-only system is about 12.8 years. For a solar and battery combination, the payback extends to 19.1 years, reflecting the higher initial investment. However, the battery adds crucial value through outage protection and eligibility for programs that can reduce its net cost. Furthermore, as utility rates potentially rise over the next 25+ years, the value of your self-generated power increases, improving the long-term return.

Local Questions Answered

Why is a battery recommended in Matthews if it makes the payback period longer?
A battery is recommended for three main reasons in 2026: 1) It provides seamless backup power during outages. 2) It allows you to qualify for Duke Energy's PowerPair rebate, which can significantly reduce the net cost of the entire system. 3) It lets you store your own solar power for evening use, protecting you from potentially lower export credit rates.
Without the 30% federal tax credit, is solar still a good investment in NC?
Yes, for many homeowners. The financial case now relies more heavily on powerful local incentives like the Duke Energy PowerPair rebate and the state's 100% property tax exemption. These programs, combined with ongoing energy savings, help ensure a solid long-term return on investment.
Will installing solar panels increase my property taxes in Matthews?
No. North Carolina provides a 100% property tax exemption for the value added by a residential solar energy system. Your home's assessed value will not increase because of the panels.
