- State and Local Incentives: Additional incentives from the state and local utility companies can further reduce the cost. For example, Duke Energy offers a rebate program, and there are property tax abatements for solar electric systems.
Return on Investment (ROI)
Payback Period: The payback period for solar panels in North Carolina is typically around 10-12 years. This means that after this period, the savings on your electricity bills will have covered the initial investment cost.
Increased Property Value: While solar panels generally increase property value, the impact in Wilmington, NC, is currently less significant compared to other regions. However, as awareness and adoption grow, this could change in the future.
Environmental Benefits
CO2 Emissions Reduction: Installing solar panels can reduce your home’s CO2 emissions by about 350 pounds per year, or around 7,000 pounds over 20 years.
Financing Options
- Cash Purchase: Provides the best long-term savings but requires a significant upfront investment.
- Solar Loans: Allow you to finance the system with little to no money upfront, though long-term savings will be lower due to interest rates.
- Leases and PPAs: These options generally provide the lowest savings and are less favorable due to potential long-term commitments and lower financial benefits.

Net Metering Policies in North Carolina
Net metering allows homeowners with solar panels to sell excess electricity back to the grid, earning credits on their utility bills. North Carolina has a net metering policy that is beneficial for solar panel owners, although recent changes have slightly reduced the financial benefits.
Key Points of Net Metering in North Carolina
- Current Policy: As of October 1, 2023, Duke Energy customers can no longer benefit from full-retail net metering. Instead, they can choose between the Bridge Rate plan and the Residential Solar Choice plan.
- Bridge Rate Plan: This plan functions as an interim solution until 2027, after which the Residential Solar Choice plan will become the sole option.
- Residential Solar Choice Plan: This plan includes time-of-use (TOU) rates and monthly netting of electricity imports and exports, which can affect the overall savings from solar panels.
- Savings Impact: The new net metering rules are expected to reduce long-term solar savings by approximately 20% and increase the payback period by two to three years.
Example of Typical Savings After Installation
Let’s consider a 6 kW solar panel system, which costs about $15,655 before incentives and $10,931 after the ITC. Here’s a breakdown of potential savings:
- Annual Savings: Approximately $1,200 per year on electricity bills.
- Payback Period: Around 11.9 years.
- 25-Year Savings: About $31,889.
Installing solar panels in Wilmington, North Carolina, can significantly reduce or even eliminate electricity costs, providing substantial long-term savings. The net metering policies, while slightly less favorable than before, still offer a viable way to maximize the financial benefits of solar energy. With the federal tax credit and potential state incentives, the initial investment in solar panels can be recouped within a reasonable timeframe, making it a worthwhile investment for many homeowners.
