How much do solar panels cost for a house in 2026?

EnergySage put the median quoted residential price at $2.57 a watt in the first half of 2026, or $30,712 for a median system of about 12 kW before incentives. An 8.4 kW system at that rate costs $21,588. Quotes commonly range from $2.20 to $3.40 a watt.

What is included in the installed price?

Panels, inverter, racking, wiring, labor, permits, and utility interconnection. Panels are well under a quarter of the total. Roof work, electrical panel upgrades, and monitoring may be excluded, so compare itemized quotes, cash price against cash price.

Why did solar prices rise in 2026?

EnergySage linked the 3.2 percent rise in the median quoted price to the lapse of the 30 percent federal credit, climbing labor expenses, and trade friction. Equipment prices have fallen over the decade; installation labor, permitting, and interconnection have not fallen at the same pace.

The median quote, and what it leaves out

Ask what solar panels cost and the honest answer is a rate, not a price: dollars per watt of installed capacity. EnergySage, which collects the quotes homeowners actually receive through its marketplace, put the median quoted residential price at $2.57 a watt in the first half of 2026, up 3.2 percent from $2.49 a watt in the second half of 2025. Solar-only quotes, systems without a battery, were $2.62 a watt, flat against the previous six months and down 1 percent on the year. The median system in that data was about 12 kilowatts, which puts the median project at $30,712 before incentives. Those three numbers, $2.57, $2.62, and $30,712, are the starting point for every 2026 conversation about solar cost, and every one of them needs a qualifier before it can be used.

The first qualifier is that a median is not a quote. A median is the middle of a spread, and the spread for residential solar in 2026 is wide. Installer quotes commonly run from about $2.20 a watt to about $3.40 a watt for comparable equipment, and the difference between the ends of that range is not a rounding error. On the 8.4 kilowatt system this site uses as its default, $2.20 a watt is $18,480 and $3.40 a watt is $28,560, a $10,080 gap for the same panels on the same roof. The payback moves with it: 9.60 years at $2.20, 12.12 years at $2.57, and 15.05 years at $3.40, holding the bill, rate, sun, and export credit fixed. Two households can buy the same system, at the same address, in the same month, and end up with paybacks more than five years apart, purely because one installer charged more per watt than the other. That is why the standard advice in this market is to collect three quotes, and why it is good advice: the spread between quotes is often larger than the value of any incentive a household is chasing.

The second qualifier is that the 2026 price is a price without the federal credit. The 30 percent Residential Clean Energy Credit ended for systems completed after December 31, 2025, so the $2.57 figure is the price a homeowner pays, not a price before a credit arrives months later on a tax return. Installers who still present a price net of the 30 percent credit are presenting a 2025 price in 2026. On the default system, the difference is $6,476. Any quote that subtracts it should be sent back for a corrected gross price before it is compared with anything else.

What the dollars per watt actually buy

A solar quote is not a quote for panels. Panels are well under a quarter of the installed price in most projects. The rest is the inverter that turns the panels' direct current into the alternating current the house uses, the racking and wiring that hold the array to the roof, the labor to install it, the permits, the utility interconnection, and the installer's overhead, sales, and warranty costs. Equipment is roughly 55 percent of the project and labor, permitting, and interconnection roughly 45 percent, which is why two quotes with identical panels can differ by thousands of dollars: the panels are the same, and everything around them is not.

That breakdown also explains why larger systems cost less per watt. Design, permitting, sales, and interconnection costs are largely fixed, so spreading them over more kilowatts lowers the rate. EnergySage's own size guide makes the point: a 5 kilowatt system was about $13,900 before incentives in 2026, or $2.78 a watt, while a 12 kilowatt system was about $31,135, or $2.59 a watt. The calculator's size ladder shows the same pattern in payback terms. A 4 kilowatt system at $2.57 a watt costs $10,280 and pays back in 13.30 years at the defaults; a 12 kilowatt system costs $30,840 and pays back in 11.07 years. The larger system is not more efficient per panel. It simply carries its fixed costs better, and it makes more power to spread the year-12 inverter replacement across.

What is not in the dollars-per-watt figure matters as much as what is. A roof that needs work before panels go on it is a separate bill, and it is the most expensive surprise in residential solar, because removing and reinstalling an array to re-roof later costs thousands on its own. An electrical panel upgrade, if the existing service cannot take the array, is another. Tree work, critter guards, and monitoring subscriptions sit in the same category: real costs that a headline rate does not include. A quote that looks cheap because it omits them is not cheap. It is incomplete. The comparison that works is the itemized quote, line by line, with the cash price and the financed price shown separately, because a loan with dealer fees can add thousands to the real cost while leaving the monthly payment looking gentle.

System-size prices at the 2026 median rate

The table below prices five system sizes at $2.57 a watt, before incentives, with the payback and 25-year net from this site's calculator at the default bill, rate, sun hours, and export credit. It is a planning table, not a price list. Your roof, your installer, and your utility decide the real numbers.

System size	Cost before incentives	Year-one production	Payback	Net after 25 years
4 kW	$10,280	5,650 kWh	13.30 years	$15,266
6 kW	$15,420	8,475 kWh	12.55 years	$24,149
8 kW	$20,560	11,300 kWh	12.17 years	$33,032
10 kW	$25,700	14,126 kWh	11.23 years	$41,915
12 kW	$30,840	16,951 kWh	11.07 years	$50,798

The right size is set by the electric bill, not by the table. A household using 11,868 kilowatt-hours a year, the default here, needs about 8.4 kilowatts at 4.5 sun hours to cover its use. A household using half that needs about 4.2 kilowatts. Oversizing past 100 percent of use is worth less with every extra panel under most modern export rules, because the extra power is sold at the export rate rather than displacing a retail kilowatt-hour. The calculator's sizing button does this arithmetic directly: it divides annual use by the kilowatt-hours one kilowatt makes where you live, and it is the fastest check on whether a quoted size matches the house it is meant to serve.

Why prices rose while equipment got cheaper

EnergySage linked the 3.2 percent rise in the median quoted price to the lapse of the federal credit, climbing labor expenses, and persistent trade friction. That combination is worth understanding, because it cuts against the usual story that solar gets cheaper every year. Panel and equipment prices have indeed fallen over the past decade. Installation has not followed them down at the same pace, because installation is labor, permitting, and interconnection, and those are local costs that rise with wages and with the complexity of each roof. The credit's end also changed installer pricing behavior: with 30 percent no longer arriving from the Treasury, the full price is visible, and some of the cost that the credit used to absorb is now negotiated in the open, between the homeowner and the installer, instead of being settled by the tax return.

The same report found a surge in third-party ownership, leases and power purchase agreements, in the first half of 2026. That is the market's answer to the credit's end for homeowners: the company that owns the system can still claim the business credit, and some of that value can reach the homeowner as a lower monthly payment. It is a real path, and it is also a different product, with different math. A leased system has no payback to calculate, because the homeowner never buys it. The comparison that matters for a lease is the monthly payment against the monthly bill saving, over the full term, with the escalator in the lease read carefully. Leases that escalate 2 or 3 percent a year can quietly hand back much of the saving they promise in year one.

The new insight

The $2.57 median is a marketplace figure, not a price tag, and the spread around it is the story. At $2.20 a watt the default system pays back in 9.60 years; at $3.40 a watt it takes 15.05 years. That 5.45-year spread, for the same panels on the same roof, is larger than the 4.11 years the ended federal credit was worth. Getting a second and third quote is worth more, in payback terms, than the subsidy that just ended.

How to read a quote without being misled

Start with the gross price, before any incentive, and the dollars-per-watt rate that price implies. Then check five things. First, is the federal credit subtracted anywhere in the quote, and if so, is it removed from the comparison price, since it no longer applies to a 2026 homeowner purchase. Second, is the price the cash price or the financed price, and what dealer fee or interest is folded into the financed figure. Third, does the quote list the panel, inverter, and racking models by name, or does it price a generic system that could be anything. Fourth, what is excluded: roof work, panel upgrades, monitoring, and the inverter replacement in year 12, which this calculator charges at $2,500. Fifth, what does the utility pay for exported power, and is the saving in the quote calculated at the retail rate for every kilowatt-hour, including the exported ones, which would overstate the saving wherever the export credit is below retail.

Run the quote through the calculator with its own numbers: the quoted size, the quoted dollars per watt, your rate, your sun hours, and your export credit. If the payback the salesperson quoted is much shorter than the calculator's, the difference is in one of those five checks, and it is worth finding which one before signing. A quote that survives that check is a quote worth considering. A quote that does not is not a bargain. It is a different set of assumptions, wearing a lower price.
