Solar Panel Cost 2026: $20,000–$28,000 Typical Range

Installing about 8 kilowatts of solar panels on a US house — the panels, the inverter, the racking, and the labor in one price, on a roof that can take them — often clusters around $20,000–$28,000. That is the typical solar panel cost. How much do solar panels cost in that scope? It is an 8 kilowatt roof array at $2.50–$3.50 a watt, not the $4 top. The cost to install solar panels, for that roof, is the same band. Solar panel cost per watt, installed, is typically $2–$4, and the typical band is the $2.50–$3.50 part of that rate on about 8 kilowatts. The cost of solar panels, for that array, is $20,000–$28,000. Solar panel installation cost is that installed price. The wider national spread, about $8,000–$48,000, covers about 4 kilowatts at $2 a watt at the low end and about 12 kilowatts at $4 a watt at the high end. A service that cannot carry the array is the electrical panel upgrade guide. The shingles under the racking are the roof replacement guide. A charger in the garage is the EV charger guide. These are typical planning ranges, not a survey and not a quote.

This page is a roof-mounted, grid-tied array on an existing single-family house. A bid may call it solar panels, a rooftop array, or a residential solar installation. It is not a main-panel swap, which is the electrical panel upgrade guide. It is not a tear-off and new shingles, which is the roof replacement guide. It is not a Level 2 charger in the garage, which is the EV charger guide. A kit from a retailer, and a single panel on a shed, are different products.

The price of the job is the equipment and the labor that installs it. Kilowatts are the first cut. The installed rate per watt is the second. A per-watt rate is a way to check a row. It is not a second bill. One kilowatt is 1,000 watts. About 8 kilowatts is 8,000 watts. Price the array the design actually names.

The rows below are ways to read one job. They are not added together. The size table is a roof-mounted array at $2–$4 a watt, equipment and labor included. The typical band is that same roof at $2.50–$3.50 a watt on about 8 kilowatts. It is not a second array on top of the size row. Use an add-on row only for a line the size row does not include. A battery the proposal already names is not a second battery. A panel upgrade the solar price already includes is not a second service change.

System	Kilowatts	Typical installed cost
A small roof	4	$8,000–$16,000
A smaller house	6	$12,000–$24,000
A common house	8	$16,000–$32,000
A larger house	10	$20,000–$40,000
A large roof	12	$24,000–$48,000

Add-on	Typical planning range
One whole-home battery, when the bid leaves it out	$12,000–$16,000
Main panel upgrade, when the service cannot carry the array	$2,000–$4,200

The add-on rows are lines the size row left out. A battery the proposal already includes is not the battery row on top. A service that can already carry the array does not get the panel row. The panel figures are the typical band on the electrical panel upgrade guide. They are not a second solar rate.

About 4 kilowatts — a small roof — is typically $8,000–$16,000. Four thousand watts at $2 is $8,000, the floor of the row and the floor of the wider spread. Four thousand watts at $4 is $16,000, the top. Four thousand watts at $2.50 is $10,000, inside the row and under the typical band. Four thousand watts at $3.50 is $14,000, inside the row and under the typical band. The whole row sits under $20,000. A 4 kilowatt array at the top of the rate is still a small array. It is not the typical band with a discount. From $8,000–$16,000 the job is the 4 kilowatt row. Do not add the 8 kilowatt row on top of it.

About 6 kilowatts — a smaller house — is typically $12,000–$24,000. Six thousand watts at $2 is $12,000, the floor. Six thousand watts at $4 is $24,000, the top. Twenty-four thousand minus $20,000 is $4,000, so the top sits $4,000 past the typical floor and still inside the typical band. Six thousand watts at $2.50 is $15,000, inside the row and under the typical band. Six thousand watts at $3.50 is $21,000, inside the row and inside the typical band. The overlap with the typical band is $20,000–$24,000. The $20,000 point is also 8 kilowatts at $2.50. Ask which array the bid is. From $12,000–$20,000 the job sits at or under the typical floor and stays inside the row. From $20,000–$24,000 the job is inside the typical band and stays inside this row. It is not the typical 8 kilowatt band. Do not add the 4 kilowatt row to this one.

About 8 kilowatts — a common house array of that size — is typically $16,000–$32,000 on the size row, and the typical band of $20,000–$28,000 is that row from $2.50 to $3.50 a watt. Eight thousand watts at $2 is $16,000, the floor of the row and $4,000 under the typical floor. Eight thousand watts at $2.50 is $20,000, the typical floor. Eight thousand watts at $3 is $24,000, inside the typical band. Eight thousand watts at $3.50 is $28,000, the typical top. Eight thousand watts at $4 is $32,000, the top of the row and $4,000 past the typical band. The overlap of the size row with the typical band is $20,000–$28,000. From $16,000–$20,000 the job sits under the typical floor and stays inside the row. From $28,000–$32,000 the job has left the typical band and stays inside the wider spread. This is the roof the typical band describes, at $2.50–$3.50 a watt, not at $4. Do not add a per-watt rate on top of this row. The per-watt reading is how the row was built.

About 10 kilowatts is typically $20,000–$40,000. Ten thousand watts at $2 is $20,000, the floor of the row and the typical floor. Ten thousand watts at $2.50 is $25,000, inside the typical band. Ten thousand watts at $3 is $30,000, which has left the typical band by $2,000 and stays inside the row. Ten thousand watts at $4 is $40,000, the top. The overlap with the typical band is $20,000–$28,000. The $20,000 point is also 8 kilowatts at $2.50. The $28,000 point is also 8 kilowatts at $3.50. Ask which array the bid is. From $28,000–$40,000 the job is at or above the typical top and stays inside the wider spread. Do not add the 8 kilowatt row to this one.

About 12 kilowatts is typically $24,000–$48,000. Twelve thousand watts at $2 is $24,000, the floor of the row and inside the typical band. Twelve thousand watts at $2.50 is $30,000, which has left the typical band by $2,000 and stays inside the row. Twelve thousand watts at $4 is $48,000, the top of the row and the top of the wider spread. The overlap with the typical band is $24,000–$28,000. The $28,000 point is also 8 kilowatts at $3.50. Ask which array the bid is. From $30,000–$48,000 the job is above the typical top and stays inside the wider spread. Do not add the 10 kilowatt row to this one.

Solar panel cost per watt

Solar panel cost per watt is the installed array, not the price of a panel with no labor named. The size rows use $2–$4, equipment and labor included. The typical band uses $2.50–$3.50 on about 8 kilowatts. Eight thousand times $2.50 is $20,000, the typical floor. Eight thousand times $3 is $24,000, inside the typical band. Eight thousand times $3.50 is $28,000, the typical top. Eight thousand times $2 is $16,000, the floor of the 8 kilowatt row. Eight thousand times $4 is $32,000, the top of that row. Use the watt line when the bid is written that way. Do not add those watts on top of a size row that already includes them.

On 6 kilowatts, $2.50 a watt is $15,000, under the typical band. Six thousand times $3.50 is $21,000, $1,000 into the typical band and inside the 6 kilowatt row. On 4 kilowatts, $3.50 a watt is $14,000, under the typical floor. On 10 kilowatts, $2 a watt is $20,000, the typical floor, and $4 a watt is $40,000, the top of that row. A quote of $2.50 a watt on 8 kilowatts is the typical floor. It is not a 12 kilowatt array with a discount. Twelve thousand watts at $2.50 is $30,000.

A rate under $2 on a large, simple roof can land under the size row and still sit inside the wider spread. Ten thousand watts at a rate under $2 can land under the $20,000 floor of that row. Ask the watts before you call it a bargain. A rate over $4 on a steep tile roof, or in a high-cost metro, can leave the size row. Eight thousand watts at a rate over $4 is over $32,000 and can stay inside the 10 kilowatt row until it passes $40,000. Ask which roof the bid priced.

Cost to install solar panels

The cost to install solar panels is this page when the equipment and the labor are one job. Solar panel installation cost is that same installed price. A bid that says installation and a bid that says solar panels are the same dollars when the kilowatts, the roof, and the labor match and both sit on the $2–$4 rate. The typical band, $20,000–$28,000, is about 8 kilowatts of that installed array. It is not a second product stacked on a size row you already have.

The cost of solar panels, as a module-only number, is not this page. The installed row includes the panels, the inverter, the racking, and the labor. A warehouse price for the modules, with the rest left out, is a parts list. On 8 kilowatts, the installed typical band is $20,000–$28,000. Do not add a module price under an installed price for the same watts.

A string inverter and microinverters are ways to build one array. The bid should name which one. They are inside the per-watt rate when the proposal is a complete install. They are not a second $2–$4 under a price that already includes an inverter. Ask which inverter the bid is. Do not add an inverter allowance on top of a turnkey rate.

A ground mount is not this roof-mount rate. The racking and the trench are a different assembly. Ask the bid to price them on their own. Do not add a roof-mount row under a ground-mount price for the same kilowatts. Solar shingles are a roofing product. They are not this panel rate. A new shingle roof, without solar shingles, is the roof replacement guide.

One whole-home battery, when the bid leaves it out, is typically $12,000–$16,000. That row is one battery of that class, installed, not a second array. On the typical band, the roof plus that battery is $32,000–$44,000. Twenty thousand plus $12,000 is $32,000, the top of the 8 kilowatt row. Twenty-eight thousand plus $16,000 is $44,000, which has left the 8 kilowatt row by $12,000 and sits inside the 12 kilowatt row, under that row’s $48,000 top. Sixteen thousand plus $12,000 is $28,000. That sum is an 8 kilowatt array at $2 a watt plus the battery floor, and it is also the typical top with no battery. Ask which one the bid is. Thirty-two thousand plus $16,000 is $48,000, the top of the wider spread. That sum is an 8 kilowatt array at $4 a watt plus a battery. Twelve thousand watts at $4 is also $48,000. Those are the same dollars and not the same job. A smaller battery can land under $12,000. A battery the proposal already includes is not this row on top.

A main panel upgrade, when the service cannot carry the array, is often $2,000–$4,200 on the electrical panel upgrade guide. Twenty thousand plus $2,000 is $22,000, inside the typical band. Twenty-eight thousand plus $4,200 is $32,200, which has left the 8 kilowatt row by $200 and sits inside the 10 kilowatt row. A service that can already carry the array does not get this row. A panel upgrade the solar proposal already includes is not a second service change.

What the range includes

The typical band assumes about 8 kilowatts of roof-mounted solar panels at a single-family house. The panels are in. The inverter is in. The racking is in. The labor is in. Ordinary permits, in this band, are part of the installed rate. The rate that lands on $2.50–$3.50 a watt is the rate this band uses. An open 8 kilowatts at $2.50 a watt is the $20,000 floor. The same array at $3.50 is the $28,000 top. The house stays grid-tied. A whole-home battery is not in the band.

How long the work takes depends on the kilowatts, the roof, and the electrical, and the bid’s schedule is the one that counts. These are not a day count on this page. Utility permission to operate is not a dollar line. The array is not producing on the day the truck leaves if the utility has not accepted it.

The floor of the wider spread, near $8,000, is about 4 kilowatts at $2 a watt. It is not 8 kilowatts someone discounted. The top, $48,000, is about 12 kilowatts at $4. Twelve thousand times $4 is $48,000. It is not the 8 kilowatt row plus every add-on. Eight kilowatts at the typical top, $28,000, a battery the solar price left out at $12,000, and a panel upgrade the service could not skip at $2,000 is $42,000. Twenty-eight thousand plus $12,000 is $40,000. Forty thousand plus $2,000 is $42,000. That sum has left the 8 kilowatt row by $10,000 and stays inside the 12 kilowatt row, under that row’s $48,000 top. Stacking those lines does not build the $48,000 job by itself. The $48,000 job is also the large roof at $4 a watt, with no battery. A ground mount, solar shingles, or more than 12 kilowatts can clear that top. Treat a number above it as more capacity, a battery, or a roof the $4 rate does not cover, and ask which one.

None of the bands include a tear-off and new shingles, which is the roof replacement guide, often $8,500–$15,000 for a straightforward architectural shingle roof. Twenty thousand plus $8,500 is $28,500, $500 past the typical solar top. Twenty-eight thousand plus $15,000 is $43,000, inside the 12 kilowatt row and not an 8 kilowatt array. Ask which project the bid is. Do not add $8,500 to $20,000 and call the sum a larger solar system. None of the bands include a Level 2 charger, which is the EV charger guide, often $1,200–$2,500 on a short run from a panel that already has capacity. Twenty thousand plus $1,200 is $21,200, inside the typical solar band, and it is still two jobs. Twenty-eight thousand plus $2,500 is $30,500, $2,500 past the typical top and inside the 8 kilowatt row. A roof that will not last the life of the array gets replaced before the racking goes down. Do not fold the shingles or the charger into the solar price.

The band is the installed price. A state rebate, a utility rebate, and any tax credit are not subtracted. Read the form before you take a number off the bid. A credit you have not received is not inside the planning range.

Removing the array later so a roof can be replaced, then putting the same panels back, is its own line. This page does not put a dollar on that line. Ask the bid to name it. A removal the proposal already includes is not a second removal.

Warranties are part of the contract, and this page is not a reading of one company’s form. A solar warranty commonly splits the panels, the inverter, and the installation, and the term on labor is often shorter than the term on the panels. A panel that cracked, an inverter that failed, and a leak the workmanship warranty excludes are questions for that form. Read it. The warranty is not a dollar line in the planning range.

Homeowners insurance and a home warranty are contracts too. A standard homeowners policy is built around sudden and accidental damage. Panels ruined by a covered storm are the kind of loss those policies sometimes respond to, and the replacement is part of that claim only to the extent the form says. Panels you chose to install are the kind of change you tell the insurer about before you treat the policy as the budget. Read the form. A home warranty may name the house and still exclude generation equipment. Neither contract is inside the planning range.

As a cross-check, not a bid: 8 kilowatts at $2.50–$3.50 is $20,000–$28,000, the typical band. Eight thousand times $2.50 is $20,000. Eight thousand times $3.50 is $28,000. Four kilowatts at $2–$4 is $8,000–$16,000, under that band. Twelve kilowatts at $4 is $48,000, the top of the wider spread. If a bid and that reading are far apart, the bid is a different kilowatt size, a battery, a panel upgrade, a steep or tile roof, a ground mount, or a price that left the labor out.

What moves the price

Driver	How it changes the bid
Size	Four kilowatts is $8,000–$16,000. About 6 kilowatts is $12,000–$24,000. About 8 kilowatts is $16,000–$32,000, and the typical band is the $2.50–$3.50 part of that row, $20,000–$28,000. About 10 kilowatts is $20,000–$40,000. About 12 kilowatts is $24,000–$48,000.
Rate	The size rows use $2–$4 a watt, equipment and labor included. The typical band is $2.50–$3.50 on about 8 kilowatts. The watt price is not a second price on top of the size row.
Battery	One whole-home battery, when the bid leaves it out, is $12,000–$16,000. A battery the proposal already includes is not a second battery. A smaller battery can land under $12,000.
Panel and roof	A main panel upgrade the service cannot skip is often $2,000–$4,200 on the panel guide. A shingle replacement is the roof guide, often $8,500–$15,000. A service that can carry the array, and a roof that can carry the racking, do not get those rows.
Roof and access	A simple asphalt roof is the array this page prices. Tile, a steep pitch, and a three-story eave slow the crew. A high-cost metro can clear the top of the typical band on a straightforward 8 kilowatts.
Shade and equipment	Shade the design did not count is not a discount. Trimming or removing a tree is a different project. The inverter type belongs inside the installed rate. It is not a second rate.

Kilowatts are the first cut, and they are not a rate times the whole roof if only part of the roof is in the design. Measure the array the drawing names. Nameplate kilowatts are not the same number as the kilowatt-hours the house used last year. A 4 kilowatt array at $4 is $16,000. Eight kilowatts at $2.50 is $20,000. The smaller, higher-rate array can cost less than the larger, cheaper one, and the gap is the watts.

The rate is the second cut, and it is a way to read one array. Adding $2.50 a watt on top of a size row that was already priced per watt is how 8 kilowatts becomes a number nobody can compare.

The same 8 kilowatts in a lower-cost area and in a high-labor city can sit at opposite ends of $20,000–$28,000 without either bid being wrong. Ask whether a battery is in, and ask whether the service can carry the array. A panel upgrade the calculation requires, a roof that still needs to be replaced, and an EV charger in the same season are the projects that show up beside this one. Price them on their own pages. Two bids that disagree about the kilowatts, the battery, and whether the labor is in are not the same job.

DIY or hire

Hire the roof array. The electrical connection, the roof attachments, and the permit are the job. A weekend crew is most likely to miss the flashing and the shutdown rules, and a leak at a mount shows up in the ceiling.

A retail kit is a different product. It is not the installed rate on this page, and it is not an 8 kilowatt roof array. The installed row is the pro price. On 8 kilowatts at $2.50–$3.50 a watt, the job is $20,000–$28,000. That is the labor and the equipment together. A house array is a hire.

Do not skip the flashing or the permit to save a day. If you are pricing a lift, an electrical connection, and a roof that still needs a leak found, you are pricing a contractor’s job without the crew. The person who sets the array should say what happens to the shingles under each mount.

Repair or replace

Leave a sound array in place when it is producing, the mounts are tight, and the roof under it is dry. One damaged panel is more equipment on that panel. A replacement panel is typically $200–$700. That whole span sits under the wider floor of $8,000. An inverter replacement is typically $1,000–$3,000. That whole span sits under the wider floor too. If the repair quote for those parts has reached the installed row for the same array, price a replacement of the array instead of a patch that costs the same.

Replace the array when the panels are failing across the roof, or when the roof under them has to come off and the panels are not worth putting back. A new array is not a repair of one cracked panel. Leaving a failing set to save the $20,000–$28,000 is how the next bid is a replacement anyway, after a second trip.

A roof that leaks, or a roof that will not outlast the array, is the roof replacement guide, and the array goes on after that roof is ready. A service that cannot carry the inverter is the electrical panel upgrade guide. A charger for a car is the EV charger guide. If the same season includes any of those, they are separate scopes. Do not fold them into the solar price.

How long a new array lasts is not a number on this page. A replaced inverter is not a warranty that every panel will keep producing. A replacement array is not a warranty that a storm will miss the roof. The bid’s scope is the work you bought.

How to use this number

Ask two or three installers for a written price that names the kilowatts, whether the price is per watt or a lump sum, whether the panels, the inverter, the racking, and the labor are all included, whether a battery is in, whether the service can carry the array, and what happens if the roof under the array needs work. Compare about 8 kilowatts of roof-mounted solar panels, installed, with $20,000–$28,000. Compare the arrays with $8,000–$16,000 for 4 kilowatts, $12,000–$24,000 for 6, $16,000–$32,000 for 8, $20,000–$40,000 for 10, and $24,000–$48,000 for 12. Compare the rate with $2–$4 a watt, and the typical slice with $2.50–$3.50. Keep the equipment and the labor inside those rows. Put a left-out whole-home battery at $12,000–$16,000, and a left-out panel upgrade at $2,000–$4,200, on their own lines.

A very low bid on 8 kilowatts is a reason to ask whether the labor and the equipment are both included, not a reason to celebrate. A quote near $8,000 should say about 4 kilowatts, not a common house array. A high bid should point at kilowatts, a battery, a panel upgrade, a tile or steep roof, or the labor market. Two or three local bids on the same kilowatts, the same roof, and the same battery choice are the number that matters. How this site sets the band is explained on the methodology page.
