The cost of solar panels in South Mills, NC (2025)

Your electric bill doesn't care about your budget. It just keeps climbing. That's the bad news. The good news? Solar panels can lock in decades of predictable energy costs in South Mills, NC while your neighbors watch their utility bills rise.

As of December 2025, the average solar panel system costs $2.28/W including installation in South Mills, NC. For a 17.12 kW system (the average system size in South Mills, NC), this comes out to about $39,091 before any available incentives, though prices range from $33,227 to $44,955. That may sound like a lot, but most homeowners see solid returns on their solar investment over the system's 25-30 year lifetime.

These numbers also don't include any potentially available South Mills, NC or local incentives, which can help lower costs.

Your solar panel cost depends on your system's size

It may seem obvious, but larger solar panel systems cost more money. We use cost per watt ($/W) so you can easily compare quotes, controlling for slight variations in system size.

If you can't shell out $11,414 in cash to pay for solar, don't sweat it. You can choose to finance your system with a loan instead. Some companies even offer $0-down loans so you can start saving on day one if your loan payments are less than your current electric bills. Just keep in mind that your long-term savings will be lower with a loan due to interest rates.

Or, for homeowners who prefer not to own their system or want to keep capital flexible, solar leases and power purchase agreements (PPAs) often provide immediate savings with no money upfront. They're not offered everywhere, though, so it's worth double checking that providers offer these types of agreements systems in your area.

The numbers we're showing are averages. The price you'll pay for solar depends on many factors unique to you and your home:

Solar is a major purchase, but you can often get the price tag to come down by being an educated shopper. Taking advantage of incentives and shopping around for quotes can help lower your cost of solar in South Mills, NC.

Search for incentives

While the federal tax credit is no longer available for systems purchased with cash or a loan, many states offer great local incentives and rebates that can further reduce your costs—so it's worth seeing what's available to you.

You can also still benefit from the tax credit indirectly if you sign a lease or PPA as long as your provider passes along those savings.

Comparing multiple solar quotes can save you money through competition and transparency. Each additional quote you receive for solar will help you find the right solar panel system at the right price.
