** What's new for 2020 **

Duke energy continues to offer its gold rush-esque incentive program. Installations completed within 90 days of the beginning of the following year prompts dozens of installers to line up at the computer terminal to claim rewards as if they were attending an Elton John concert.

North Carolina’s major energy suppliers have met their Renewables Portfolio Standard (RPS) goals (we’ll get to exactly what an RPS is in just a second). The utilities have reined in their own solar incentives.

But it's not all bad news! Solar is cheaper than ever, and the cost and payback time of a solar system is better than in some states. The legislature could do more to ensure a sunny future for solar by strengthening the state’s Renewables Portfolio Standard, and renewing the expired state tax credit, but solar still makes a good deal of sense here.

How to pay for solar panels in North Carolina

The chart above shows the 25-year returns for an investment in solar whether you choose to purchase a system with cash or pay over time with a loan. That might look a little complicated to you, so let's break it down:

The green bars show the return if you pay up front. As you can see, there's a big payment (negative) in year 1, which gets slowly erased by elecricity savings over time. The orange bars, on the other hand, show what happens if you take a solar loan or Home-Equity Line of Credit (HELOC) to pay for the system. You don't put any money down, and you still get the tax credit, meaning you actually come out ahead in year 1. The bars dip after year 6, because your loan payments (over a 15-year term) will exceed your energy savings by a little each year. Still, in the end, you'll come out thousands of dollars ahead over the 25-year estimate.

Finally, the blue bars represent a similar loan scenario, but for a smaller solar system. The loan and savings will be smaller, but it's a great way to go solar, even of you don't have a lot of cash or equity. Usually this is where we'd show you the savings with a solar Power-Purchase Agreement, but North Carolina is one of only 5 states in the country that ban third-party ownership.

There's still a lot to love about solar in the Tar Heel State. Read on to find out more about each option!

How much can solar panels on roof save you?

Option 1: Paying cash for solar

Paying up front used to be the only way to get panels on your roof, and it's still the option that allows you the most control. But it isn't the best option from a percentage return on investment standpoint—that award goes to the solar loan.

Still, an outright purchase returns the most money over time, because you own the system from day one and reap all the benefits—including a Federal solar tax credit of 30% of the costs, and some decent energy bill savings. In our example, you put down $16,250, but by the end of year 1, those incentives and energy savings will erase a bunch of it. Over 25 years, your system will have produced nearly $13,000 in income. You'll be earning that over time, just like putting money in a retirement account. Here's how solar compares to an alternative investment:

Here’s how the numbers work for a North Carolina solar purchase of a 5-kW rooftop solar system:

  • Installing a typical 5-kW solar system should start at about $16,250.
  • First, subtract your energy bill savings of $686, reducing your year-1 investment to $15,564.
  • Since the Feds calculate their incentive based on out of pocket costs, you'll get 30% of that back as a tax credit. Subtract $4,875, for a new price of $10,689. Note: you can take the credit several years if you don't owe that much in Federal taxes this year.
  • Your energy bill savings will grow over the life of your system as the price of electricity goes up. Your system will pay itself back after 14 years, and you'll end up with $12,926 profit at the end of your panels' 25-year warranty. The rate of return on this investment is 6.7%. That's pretty good!
  • On top of those profits, your home's value just increased by just about $18,000, too (your expected electricity savings over 20 years)!
  • And speaking of doing good for the environment... your system will create some green for the earth by not using electricity from fossil-fuels. In fact, the energy you’re not using has the carbon equivalent of planting 106 trees a year, every year your solar power system is humming.
Keep in mind, the numbers above are based on an average home in North Carolina. If you're ready for a custom quote for a solar panel system, our network of experts are on call to assist you. Simply sign up for personalized assistance on our special solar deals page.

Option 2: Using a loan to pay for solar

This is where we tell you that taking a loan for solar panels is a no-brainer, because it means investing in an income-generating asset. It's true! As you can see from the chart above, you'll start out with a big windfall, because with a loan, you're not putting any money down, and you get the Federal 30% solar tax credit just like if you paid up front for your system.

You'll end up paying a little more for loan payments than you'll save on energy costs, but the key here is that you'll pay the loan off in year 15, and start saving tons of money every year after, because you'll own the system outright. You'll end up $7,540 to the good after 25 years, which is great for an investment where you put nothing down!

A solar purchase like this will make sense for you if the following is true about you and your current situation:

  • You can qualify for a solar loan or home-equity line of credit (HELOC) for with a fixed rate of 4% or lower and a 15-year repayment period.
  • You have an appetite for making a little money with a long-term investment, while also producing benefits for the environment.

Here’s how the numbers pencil out for a North Carolina solar purchase with a loan:

  • Installing a typical 5-kW solar system should start at about $16,250. That's how big your loan will need to be to cover it.
  • The electricity bill savings in the first year of operation will total $686, but your loan payments will be $1,442 for a difference of $756, or about $63 per month.
  • Then comes the tax credit! The Feds will give you 30% of the cost of your system back at the end of the year; that's $4,875. After the first year, you'll come out $4,119 ahead, which will help eliminate the burden of loan payments.
  • When your loan’s paid off after year 15, you’ll start to see over $1,000 per year in savings until the end of your system’s life.
  • For our 25-year estimate, you'll see pretty nice returns, to the tune of $7,540 after all the payments. That's a huge amount of money for a zero-down investment!
  • Finally, the environmental benefits cannot be overstated. Operating your system will take as much carbon out of the air as planting 104 trees every year!
Keep in mind, the numbers above are based on an average home in North Carolina. If you're ready for a custom quote for a solar loan, our network of experts are on call to assist you. Simply sign up for personalized assistance on our special solar deals page.

Option 3: Buying the electricity, not the panels with a Power Purchase Agreement (PPA)

North Carolina does not offer solar Power Purchase Agreements or leases. Perhaps it would be a good idea to contact a solar advocacy organization and ask them to fight for solar in your state!

North Carolina Solar Policy Information

Ever wonder why solar seems to be everywhere in some states, but not in others? We did too.

State legislatures and public utilities commissions can enact rules to make solar power accessible for everyone. Favorable rules explain why some of the cloudiest states—New York, New Jersey, and Connecticut, are doing so well with solar, and yet some of those with the most natural solar resources—like Alabama, Mississippi, and Georgia—are doing so poorly.

Below is important information about the public policy, rules, and economic reasons that affect your ability to go solar here in North Carolina:

North Carolina's Renewable Portfolio Standard

12.5% by 2021

Grade: C

North Carolina's Renewable Portfolio Standard grade

A Renewables Portfolio Standard (“RPS”) requires utilities in the state to eventually source at least a certain percentage of their electricity from clean, renewable sources like solar panels.

North Carolina’s RPS, first passed in 2007, requires all investor-owned utilities to produce 12.5% renewable energy by 2021. Municipal utilities and electric cooperatives have a lower goal of 10% renewables by 2018. The RPS also includes a small carve-out for solar power of 0.2% by 2018. That ain’t much, but a mandate is a mandate.

In this case, though, the mandate has already been surpassed. North Carolina is one of the nation's top solar markets. As an addendum to this information, it's worth noting that in 2018, Governor Roy Cooper signed an executive order mandating that the state reduce greenhouse gas emissions by 40%. Though not an "RPS law" per se, this mandate will have a great effect on how much solar growth the state continues to see. Analysts at PV Magazine have identified electricity generation as the #1 place for reductions, meaning the potential for 25 gigawatts of new solar generation in North Carolina by 2025.

North Carolina's Solar carve-out and SRECs

.2% by 2020

Grade: D

North Carolina's Solar Carve-out grade

The solar carve-out in North Carolina’s RPS states that 0.2% of the state’s electricity must be generated from solar by 2019. If you think that seems low, you’re right. The North Carolina solar carve out numbers have already been achieved by the state’s utilities. A strong RPS with an expanded carve out for solar would go a long way toward bringing better incentives to North Carolina homeowners again.

Learn more about Solar Carve-outs

North Carolina Electricity Prices


Grade: D

North Carolina's Electricity cost grade

The average cost of electricity here is 11 cents per kilowatt hour (“kWh”). That’s really cheap! Even cheaper than the national average of 13 cents/kWh. Why is energy so inexpensive? Oh, only because coal and other destructive fossil fuels are generating all that energy. No biggie. NOT GOOD! When all of the fossil fuel we’re burning starts to catch up with us, new regulations and scarcity is going to cause energy prices to rise, and rise, and rise. All those rising rates are going to cost you boatloads! That is… unless you are making your own power from say, a solar power system.

Find out why electricity prices matter

North Carolina Net Metering

Statewide for big utils

Grade: B

North Carolina's Net Metering grade

North Carolina law requires all three of North Carolina’s largest electric utilities –Duke Energy, Progress Energy, and Dominion North Carolina Power– to make full retail rate net metering available to customers. So, any extra kilowatt hours you produce in a billing month are carried forward as a credit to your bill the next month at the full retail rate. That’s great!

What’s not so hot is that all unused credit transfers to the utility without compensation at the beginning of the summer season. You don’t get a check for your unused credits under the net metering law, the way you would in other programs.

We can’t be too hard on North Carolina individually, since that’s a shameful trend we’ve seen in a lot of states now, but we’re still not happy about it. Your surplus should be your surplus, no matter how long you hold on to it.

Of note, North Carolina has also made it easier for people with existing solar installations to add in battery storage, without having to wait in the interconnection queue all over again.

Learn more about net metering

North Carolina Interconnection Rules


Grade: B

North Carolina's Interconnection Standards grade

"Interconnection" refers to the rules that are in place about what needs to happen before you can get your solar system up and running with your utility company. North Carolina's interconnection policies are a mixed bag.

We like that small installations are eligible for fast track application status, but we don't like that the state leaves it up to utilities to decide whether they want to require redundant external disconnect switches and insurance, and impose fees on interconnection applications. We'd prefer to see a more streamlined, statewide policy.

North Carolina Solar Incentives

Next to high electricity prices and net metering, solar incentives have traditionally been the most important factor for whether home solar power makes financial sense in a state. In the past, some states with otherwise lousy policy had tremendous incentives that drove down the up-front cost of going solar so much that homeowners could save oodles of money even without net metering or a good RPS.

These days, the big incentive most people can get is the Federal Solar Tax Credit that earns you 26% of your total system costs back after just 1 year. State incentives play less of a role than in the past, but some really good ones are still out there, ready to help homeowners go solar and save money before you know it.

Let's see how North Carolina measures up:

The availability of state solar incentives for residential solar systems was sourced from the Database of State Incentives for Renewables and Efficiency, utility company websites, and the state public utility commission.

North Carolina Solar Power Rebates

$600 per kW (Duke and DEP)

Grade: A

North Carolina's Solar Rebates grade

North Carolina’s solar rebate program covers all customers of Duke and Duke Energy Progress. The program provides rebates of $.60 per watt for homeowners, so a typical 5-kW system at an average cost before rebate of $3 per watt would cost around $12,000 instead of $15,000. That price could be further reduced by the 26% federal solar tax credit to around $9,000. That's a huge reduction in cost, just after 1 year!

The rebate applies to installations between 2018 and 2022, but includes installations completed within 90 days of the program date every year. This means the 2020 rebates will be scooped up by people whose installations were "completed" in October through December, 2019. Rebates will still be available for people who install in 2020 and 2021, but probably not 2022, because all the late-2021 people will apply immediately in 2022.

Rebates are awarded on a first-come, first-serve basis, and considering how fast the previous year’s program was fully subscribed, it'd be a good idea to be ready to file for your North Carolina solar rebate at 9 AM on January 1st, of next year.

North Carolina Solar Tax Credits


Grade: F

North Carolina's Solar Tax Credits grade

North Carolina had one of the country's most amazing solar tax credits. Unfortunately, it expired in 2015, and nothing has come in to replace it.

Learn more about state solar tax credits

Property Tax Exemption


Grade: B

North Carolina's Solar Property Tax Exemptions grade

In addition to that awesome state solar panel tax credit, North Carolina gives you a little long-term love on your taxes as well when you install a solar power system. You see, when you install a solar power system, your home increases in value because of the anticipated savings in electricity costs. Exempting property value increases from solar power systems from accompanying property taxes is an easy way to incentivize solar power. North Carolina seems to agree; 80% of the home value increase from your solar power system is exempt from property taxes. That’s not the 100% exemption we’ve seen in a lot of states but… well… it’s 80% of the way there!

Sales Tax Exemption


Grade: F

North Carolina's Solar Sales Tax Exemption grade

Unfortunately the equivalent sales taxes exemption that many states also have passed is a big fat 0% of the way there. As in, there is no sales tax exemption for the purchase and installation of solar power systems here. That’s a real shame. Sales tax exemptions help the local solar industry in addition to the customer, so they’re a double win, when such exemptions are in place that is.

Low-income Solar Programs

The consensus on North Carolina solar power rebates and incentives

For a state without a super-strong RPS, the prospects for solar in North Carolina are pretty impressive. The payback timeframe here is still superb – for now. With the federal solar tax credit saving you bundles of cash up front and the possibility of that big Duke rebate, North Carolina has a very respectable payback timeframe. That’s if you can get all the benefits. The patchwork nature of the incentives and the weak RPS goals mean we can’t give North Carolina better than a “C,” even though it’s possible to beat the bank here in the Tar Heel State.

    I decided not to go solar on my home for now. the Duke solar rebate was used up in a few hours and no one knows if it will come again. forget it. The bigger problem is the realistic effect on your home’s resale price. According to every real estate professional I have talked to (in the Cary area, mind you) solar can actually REDUCE the resale value of your house, so be sure you plan to keep your house for at least long enough to breakeven. This is because the general public buying homes is still wary and confused about solar power: some don’t like the looks, some are afraid of maintenance costs, some just don’t like all the assumptions behind long term profitability, and some just fear that people like them won’t want to buy a solar home. THIS IS A REAL PROBLEM and needs to be addressed more realistically. I really want to go solar and will have to wait until we move to a place we will stay in over the longer term.

      I would check Zillow’s most recent real estate study on the impact of purchased solar systems. They found a national increase of at least 4.1% to the value of the home!

    I recommend everyone considering installing solar photovoltaic panels do a ROI analysis. Even with today’s federal/state/energy company incentives; you should do a ROI analysis to identify the time it may take to realize cost savings so that your expectations are reasonable and to migitage possible disappointment. I commend everyone who is especially concerned about creating a cleaner enviiroment. Working together as customers (residential; industrial; commercial) and with legislation (like it or not), and unless you’ve been living under a rock or totally off the grid (lucky you); we know that the sulfer dioxide (SO2) has to be removed/scrubbed before coal is emitted into the atmosphere. I was recently told that the US exports more coal to China than 1) used in the US or 2) any other country. There’s a sign.. Just watch a news story recorded in China and look at the smog and the number of people wearing respiratory masks not related to medical epidemics. Very smart people in my opinion. If you are considering solar energy for industrial use, you’ll need to assess the effect of a potential power failure to sensitive materials used in your manufacturing process. Momentaries or sustained outages could cause your material to solidify causing financial loss of useless material and having to shutdown your operation for cleanup intererring with another cost loss – sending employees home because of the inability to remain productive. In closing, there is a lot of excellent information on solar energy on the Internet (review scientific sites vs. sales sites). One ot the most currnent interesting stories, is the largest solar farm being built in the desert in India!

    Unless you mean turn EVERYTHING off during the day, net metering won’t mean anything to you with 300 watts, because your fridge alone will use what that much panel produces. Throw in a few “phantom” loads like a clock or two, your TV/sat dish/DSL router/etc, and you have nothing to worry about with net,because you won’t be producing any excess at all.

    very informative site.

    The Energy Policy Act of 2005 under Sec.1251, all public electric utilities are now required to make available upon request Net Metering to their customers.

    So i bought a couple solar panels and a power inverter, 300 watts not much but being a single guy i can turn off everything when i go to work and my meter will spin backwards all day.
    The Act says upon request so i requested the power company get me set up. Even after i informed them of the Energy Policy Act and that on their own website it says that they do offer net metering, i was told they do not have to and they will not. Can they still deny net metering to their customers really?

    Zachary, we installed a solar water heater in September 2007 with fantastic results. We live in Hillsborough, NC and have a southeast facing roof. In February we’ll start getting 120 degree temps from the sun leading to summer when it turns itself off at 175 degrees. The tough months are October when the leaves are still in and the sun has dropped on the horizon or if we get a lot of rainy/cloudy days. During the winter we use the electric backup when we need to but keep it off otherwise. In all we are thrilled with our purchase and are looking into getting PV as soon as possible.

    Has anyone done a solar water heater install or a full home energy system install in Raleigh, NC? What was the cost? The results? I’m very interested!

    Does anyone know if it is better to buy the argon filled windows or not? How good of an investment are they? I want to reduce my energy bill but the contractor told me it would take about 22K to replace about 30 windos.. doesn’t that sound corrrect?

    Hi Dan, This looks great, but you may need to update the “Example 3KW System” to reflect the new Federal Tax credit (it is still shown as $2000).
    Also I don’t understand why the 6.21 KW system requires 407sq ft and the “Example 3KW system requires 600 sq ft

    Thank you. Very informative for those of us interested in alternative home power and the cost/benefit ratio of implementation.
