How much do solar panels cost in the U.S. in 2017?

solar panels cost in the u.s. graphicYou’ve probably heard about how solar energy can reduce your electricity bills, but how much do solar panels really cost? The easiest way to calculate the average cost of solar panels is to look at its price in dollars per watt, which is relatively consistent across the United States.

How much do solar panels cost?

In 2017, most homeowners are paying between $2.87 and $3.85 per watt to install solar, and the average gross cost of solar panels before tax credits is $16,800. Using the U.S, average for system size at 5 kW (5000 watts), solar panel cost will range from $10,045 to $13,475  (after tax credits).

That’s nine percent lower than it was a year ago, and solar panel system costs are continuing to fall. However, to really understand what a single solar panel will cost and what a complete solar system will cost, it’s important to compare prices quoted to homeowners in your area – total costs can vary depending on the state that you live in.

Average cost of solar panels based on system size

Knowing the average cost per watt is helpful, but what does $3.16/watt actually mean for you? The cost of installing solar on your home or business depends on how much electricity you want to generate – a bigger system will cost more, because you’ll need to buy more equipment and more labor will be needed to install it.

The average solar energy system size in the U.S is approximately 5 kilowatts (kW). Based on the average price of $3.16/watt, a 5kW system would cost $11,060 after tax credits. Below are some average 2017 quotes for other solar energy systems by size:

  • 6kW solar energy system cost: $13,300
  • 8kW solar energy system cost: $17,700
  • 10kW solar energy system cost: $22,100

These prices reflect the cost of a solar energy system after deducting the federal solar tax credit, which reduces your solar system cost by 30 percent. Some states, local governments, and utilities also offer rebates and other tax incentives that can further reduce the solar system costs in your quotes from solar installers.

The price of solar panels will also vary from state to state. EnergySage analyzed quote data from the EnergySage Solar Marketplace to develop a range of solar panel system prices for top solar states:

NOTE: These ranges are system prices after the 30 percent federal tax credit for solar

Remember, while bigger systems may cost more, they also should result in more savings. If you need to install a 10kW solar energy system to cover all of your electricity use, you might have to pay more out of pocket, but you’ll be cutting a significant monthly expense – your utility bill – and saving more money as a result. $0-down, low-interest solar loans are becoming increasingly common, making it even easier to buy a solar panel system and maximize your solar savings. For more information about the average cost to go solar in both these and other states, you can compare prices and installers across the country for 3.5kW, 4.5kW5kW6kW, 7 kW8 kW and 10kW solar systems.

Solar energy installation cost by state (dollars per watt)

As interesting as it is to look at average solar panel cost in the United States, it’s also very helpful to understand what solar will cost in each state. Prices can vary significantly depending on where you live. A number of factors impact this variation – one of the most influential is the cost of electricity. That’s one reason for why Florida’s average solar cost is so much lower than the cost of solar in Massachusetts – electricity costs in the Northeast are high when compared to the rest of the U.S. Take a look at the table below, which contains average prices by state in 2017.

2017 solar prices: average cost per watt by state

The biggest takeaway from this data isn’t that some states are “better” than others when it comes to solar prices: it’s that solar panel cost is low and affordable across the board. Almost every state falls within a $0.40 cent margin of the $3.16 national average for 2017. An additional takeaway is that many of the top 10  solar states in the U.S. for installed capacity are higher than the national average for cost per watt (including the nation’s leader California). Clearly, solar isn’t only worth it in the regions of the United States where costs are extremely low – there is a healthy trend of adoption across the states without direct correlation to lowest cost per watt.

How much does a single solar panel cost?

Many homeowners are wondering how much a single solar panel costs as a way to understand the overall breakdown of their system or to calculate estimates for DIY solar projects. The simple answer is that it depends on the amount of leverage a buyer has, the type of panel, and the size of the system. For example, because solar installers have direct relationships with distributors and can buy in bulk, they can often purchase solar panels at a rate much lower than the average consumer. Solar companies can typically get a single solar panel at a price of $0.75 per watt. Therefore, if the solar panel output is 250 watts, that single panel might cost you $187.50. However, if a homeowner is trying to buy one or two panels on their own for a small DIY project, they will likely pay closer to $1 per watt. That means the same solar panel could cost closer to $250.

For those looking for a range for the cost of solar panels, the cost will run from as low as $0.85 per watt to $1.25 per watt with output ranging from 150W to 350W for a typical solar panel. If those numbers seem low, remember that an installation has added costs thanks to the inverters, solar batteries and other additional equipment needed for a complete solar energy system. Overall, there’s no question that the equipment will be significantly cheaper when working with a solar installer rather than trying to find a deal online as a consumer.

Factors that impact the cost of solar panel installation

A home solar quote contains the all-in price that you’ll be expected to pay when you install a solar energy system on your roof. As you start to explore solar offers for your home, you’ll notice that there are pricing variations between installers – what are the factors that make up the cost of your solar energy system?

First, there’s the equipment. Not all solar panels (or inverters) are created equal, and more efficient equipment comes with a higher price tag. More efficient, higher-quality equipment comes with benefits that may be worth the added cost, however: better hardware can produce more electricity with the same amount of sunlight, and often comes with a more comprehensive warranty, too.

While equipment costs make up a significant portion of your solar energy system quote, the cost of permits and labor are also a factor. Typically, you will have to pay a fee to get your solar energy system connected to the grid. Additionally, there’s a significant amount of manpower required to take your solar idea to a reality – designing a system, coordinating a site visit, filing permits, and installing the solar panels all take time and cost money.

The characteristics of your home can also play a part in your total costs. If you have a south-facing roof that slopes at a 30-degree angle, installing solar on your home will be very easy, because there are no additional accommodations to be made. Conversely, if your roof has multiple levels, dormers, or skylights, the additional effort to finish the installation may bring (slight) additional costs.

Another factor that can increase the cost of your solar energy system is marketing and sales spending. Solar installers spend money trying to attract customers, whether through phone calls, door-to-door salespeople, flyers, or other forms of direct advertising. Luckily, this is a cost you can control: by using an online comparison-shopping platform like the EnergySage Solar Marketplace, you can lower the costs your installer would otherwise incur by trying to market to you.

How much can you save with solar?

So how much are your neighbors actually saving over 20 years as a result of installing a solar energy system? As you might expect, this depends on where you live. For example, homeowners will save about $38,000 on average in Portland when they go solar. In Boston, homeowners will save $63,000 on average, and in Los Angeles, homeowners can save a whopping $90,000 over 20 years.

Top cities for 20-year solar savings in 2017

Your solar panel payback period will also depend on where you live. The average U.S. household can break even on their solar energy system in just 7 years, but in many cities that number is even lower – Jersey City, Washington DC, and Boston all have payback periods of six years or less.

Three Tips for Solar Shoppers

  1. Homeowners who get multiple quotes save 10% or more

    As with any big ticket purchase, shopping for a solar panel installation takes a lot of research and consideration, including a thorough review of the companies in your area. A recent report by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) recommended that consumers compare as many solar options as possible to avoid paying inflated prices offered by the large installers in the solar industry.

    To find the smaller contractors that typically offer lower prices, you’ll need to use an installer network like EnergySage. You can receive free quotes from vetted installers local to you when you register your property on our Solar Marketplace – homeowners who get 3 or more quotes can expect to save $5,000 to $10,000 on their solar panel installation.

  2. The biggest installers typically don’t offer the best price

    The bigger isn’t always better mantra is one of the main reasons we strongly encourage homeowners to consider all of their solar options, not just the brands large enough to pay for the most advertising. A recent report by the U.S. government found that large installers are $2,000 to $5,000 more expensive than small solar companies. If you have offers from some of the big installers in solar, make sure you compare those bids with quotes from local installers to ensure you don’t overpay for solar.

  3. Comparing all your equipment options is just as important

    National-scale installers don’t just offer higher prices – they also tend to have fewer solar equipment options, which can have a significant impact on your system’s electricity production. By collecting a diverse array of solar bids, you can compare costs and savings based on the different equipment packages available to you.

    There are multiple variables to consider when seeking out the best solar panels on the market. While certain panels will have higher efficiency ratings than others, investing in top-of-the-line solar equipment doesn’t always result in higher savings. The only way to find the “sweet spot” for your property is to evaluate quotes with varying equipment and financing offers.

For any homeowner in the early stage of shopping for solar that would just like a ballpark estimate for an installation, try our Solar Calculator that offers up front cost and long term savings estimates based on your location and roof type.

      In Florida——> Starting November 1st, 2016: Any customer of Peace River Electric Coop who puts up solar panels has to sign a Solar Interconnection Agreement which now includes a penalty of $5.00 per kilowatt — (usually 11 or 14 cents per kW) — for every kilowatt of power that is used during and after 15 minutes of higher than usual power usage. This can easily turn into an additional $100-$150 dollars extra added to your bill per month, just because you put up solar panels or generated your own electricity using a renewable energy source.

      We are a captive customer base and we are being raked over the coals (literally, as much of the power comes from coal-fired power plants) paying 11 and 14 cents a kW; while FPL customers pay 6 cents a kW.

      Peace River Electric Coop not only refuses to provide an incentive for going solar…but is actively punishing the customers who do.

    The problem in the US is bureaucracy. The federal tax incentive is a tax credit of 30%, not a rebate. Most Americans cannot utilize this incentive since their tax bill is too low. Also, big utility companies are fighting solar by not paying the consumer anywhere near the same rate for our electricity that they are charging us for theirs. And sadly, big utilities grease politicians to keep solar on the fringes. Florida, an ideal state for solar, offers ZERO state or local incentives. Florida utilities are vehemently opposed to solar since Florida averages over five hours of “usable” sunlight per day, it would severely decrease their obscene profits. One Florida utility, JEA, is actually trying to sell solar generated electricity for a HIGHER price to consumers than coal generated! In the link to the video, the spokesperson cannot even keep a straight face while spewing the dogma.

      Utility companies fighting solar? Are you effing kidding? Moron. .Not true. My utility company gave me a 25% rebate for my solar install. Most Utes do because it’s cheaper to reduce excessive loads by reducing demand through home solar systems than it is to add capacity by building new plants. Stop drinking the leftist koolaid.

        our country/s energy use is manly fossil fuels which are obviously bad for our environment, our country’s use of renewable energy sources such as solar energy is only 10%. now if we put solar panels on each home not only would it increase the amount of renewable energy we use each year but it would also decrease the amount of pollution and decrease the electricity bill on your house so you would pay off that solar panel instead of paying a bill every month.

        That is rare. Most jurisdictions charge you for going off the grid. utility companies operate based on per building planning. When they lose service they try to make it up by charging you a fee.

        Our county offered a five-yr 50% RE tax break for people who either built or remodeled to exceed the state energy standards by at least 20%. When the federal Energy Star rating system was introduced it met with out County’s new guidelines; so everyone started to build and remodel to meet the criteria for the RE tax credit. The County immediately went into private session to block the use of the law! The initial builders who applied for the credit received it (I believe there were 10-12 residences and one business that were approved), but in two months time the credit was changed and there are no energy incentives at this time. It looked great on the website for twenty years, but as soon as people tried to use it all hell broke loose.

        Everyone cares about energy until someone is reminded someone has to pay and someone has to lose.

    Regarding this: “Based on the average price of $3.70/watt, a 5kW system would cost $13,000.”
    How come? $3.70 times 5,000 equals $18,500… Same with other system sizes.

      Hi Michael,
      The $3.70/watt price is before any tax credits or rebates. The prices that we list for a full solar energy system reflect the cost after deducting the federal solar tax credit, which reduces your solar system cost by 30 percent.

      Thanks for reading!

      1. samg

        The tax credit deduction only works if you have a positive tax due. If your income is low enough then no matter 30% or 100% it is not benefiting you at all since you can not reduce your tax due lower than zero. Am I correct?

        Reply
        1. Sara Matasci Post author

          That’s correct – you have to have tax liability in order to get the refund. However, while you cannot reduce your taxes due to below zero, any remaining benefit from the ITC can be carried over into future years. Take as an example a solar energy system that costs $10,000, which means you are eligible for a $3,000 refund. If your federal taxes only come out to $1,500, you can get $1,500 in one year and $1,500 the next year.

    We live in IREA territory in Colorado where they have established a demand charge now where if you have solar and end up supplying more than 90% of your power from solar they will charge you 10-20 times the cost per watt when you pull off the grid. We were told that our system can only be designed and installed to produce 60% of the annual watt usage of the home. If we do that we’ll pay the same rate we are now for our electricity. This is nuts! How can the government allow this disincentive?!

    The reason for electric grid companies charging more per unit of electricity is to make up revenue loss due to decrease in volume. Any business has to cover fixed costs to stay viable. Although level of demand for grid energy is decreasing, the grid will need to be viable absent storage technology that is capable of providing energy reliably and on demand as consumers have become accustomed. In other words, at present the grid is needed as insurance.

    All the information is incorrect. I current own a solar system for my house and I live near Houston,TX. The average cost per watt is $1.88 per watt after all rebates. I also had quotes with $1.80 per watt but it was all cash. People are getting terrified with abnormal prices that they see online and they never think about how the industry is changing and what competition is doing.

    I have a 2 Apt house with 2 meters. The bills are about $60 each on average, or $120 a month.
    This is mostly cloudy upstate NY. If I spend $20,000 on a system it will provide perhaps 1/2 of my electric needs, so save maybe 40% of those bills because the meters each cost $9 minimum per month.
    So it’s $20,000 for a system that degrades to save $50 a month.
    Well I have a $20000 REIT that pays $65 a month and never loses value.. I pay about $10 a month on assorted taxes that is then given to people who waste their money and mine with solar panels.

      Not sure where u get your info, but a $20,000 system before credit would be about 8kw… which would produce 9000kw of electric per year in western pa. At a savings of $.12 per kwh… 9000 x $.12 = about $1080 per year, which is about $90 per mo savings. As electric rates increase… and trust me… they will… the savings will increase

    In order for the article to be fair, comprehensive and ultimately useful to rate-payers, it should note and detail a number of topics which it omits: federal, state, and municipal as well as utility credits, subsidies and technical support that lower the cost of installation and operations. Moreover, Fannie Mae and Freddie Mac have a green mortgage program with participating lenders which provide better terms and rates. Finally, a home with solar panels and a demonstrable reduction in utility costs will have more market value at resale. All of these factors and policies offset the cost of solar installations and promote market penetration which will ultimately lower the actual, non-subsidized costs of solar arrays.

      Mikey, I can’t respond to all of your comments, but I can say that we just installed solar panels about 6 weeks ago. They came with a 20 year warranty from Solar City, which was recently purchased by Tesla, I don’t believe the inverter is covered for that long. If damage to the roof is caused by the panels, it is covered by the warranty. We have a 2-year old tile roof, if it ever needs repairs Solar City will remove the panels and put them back free of charge (at least that is what is in our contract, as I understand it).
