Solar Panel Cost by State in 2026: Complete Price Guide (All 50 States)
The solar landscape shifted dramatically on January 1, 2026, when the federal Investment Tax Credit (ITC) expired for residential installations. Homeowners who go solar in 2026 face the full sticker price without the 30% federal discount that drove millions of installations over the past decade.
But that does not mean solar is dead. Far from it. Equipment costs continue to fall, state-level incentives still deliver real savings in many markets, and electricity rates keep climbing — making the math work in more places than you might expect.
This guide breaks down solar panel costs for every state in 2026, including average price per watt, total system costs, available incentives, net metering policies, and realistic payback periods. Whether you are in sunny Arizona or cloudy Oregon, you will find the numbers you need to make an informed decision.
Key takeaway: The national average for a residential solar installation in 2026 is $2.50–$3.50 per watt before incentives, which translates to roughly $19,873 for a typical 6–8 kW system. Your actual cost depends heavily on where you live.

National Averages at a Glance
| Metric | 2026 Average |
|---|---|
| Cost per watt (before incentives) | $2.50–$3.50 |
| Average system size | 6–8 kW |
| Average total system cost | $17,500–$24,500 |
| Typical system cost (midpoint) | ~$19,873 |
| Federal tax credit | $0 (expired Dec 31, 2025) |
| Average payback period (no federal ITC) | 9–15 years |
These figures represent gross costs before any state or local incentives. In states with strong programs — such as New York, Massachusetts, or Illinois — net costs after state incentives can drop significantly.
The Post-ITC Reality
For over a decade, the federal Investment Tax Credit slashed 26–30% off residential solar costs. That safety net is gone for homeowners in 2026. Here is what that means in real dollars:
- A $20,000 system in 2025 cost roughly $14,000 after the 30% ITC
- That same $20,000 system in 2026 costs $20,000 (unless state incentives apply)
This makes state-level incentives, net metering policies, and local electricity rates more important than ever. The states that maintained strong solar programs are now the clear winners for solar ROI.
Solar Panel Cost by State: All 50 States
The table below shows average solar costs for a residential system in each state. Costs are shown before state incentives but after the federal ITC expiration. Payback periods factor in average electricity rates, available state incentives, and net metering where applicable.
How to read this table:
- Avg. Cost/Watt = Gross installed cost per watt before state incentives
- Avg. System Cost = Based on a typical system size for that state (6–8 kW)
- Key State Incentives = Major state-level programs still active in 2026
- Net Metering = Whether the state offers full retail, partial, or no net metering
- Payback Period = Estimated years to recoup investment after incentives

If upfront cost is your biggest concern, these states offer the lowest installed prices per watt:
| Rank | State | Avg. Cost/Watt | Avg. System Cost (7 kW) | Why It's Cheap |
|---|---|---|---|---|
| 1 | Arizona | $2.30–$2.70 | $17,500 | High installer competition, strong sun reduces system size needed |
| 2 | Texas | $2.30–$2.80 | $17,850 | Deregulated market, massive installer base, low labor costs |
| 3 | Florida | $2.40–$2.90 | $18,550 | Tax exemptions on sales and property; competitive market |
| 4 | Nevada | $2.40–$2.80 | $18,200 | Desert sun, growing installer competition, tax abatements |
| 5 | New Mexico | $2.40–$2.80 | $18,200 | Low labor costs, excellent solar resource, 10% state tax credit |
| 6 | Utah | $2.40–$2.80 | $18,200 | Growing market, low cost of living keeps labor affordable |
| 7 | Oklahoma | $2.40–$2.80 | $18,200 | Low labor and permitting costs |
| 8 | North Carolina | $2.50–$2.90 | $18,900 | Mature solar market, competitive pricing |

| 10 | Wisconsin | $2.80–$3.30 | $21,350 | Cold-weather installation challenges, shorter season |
Top 10 Best ROI States for Solar in 2026
This is the list that matters most. ROI factors in system cost, state incentives, electricity rates, net metering value, and solar production. Even without the federal ITC, these states still deliver strong returns.
| Rank | State | Avg. Cost/Watt | Electricity Rate (avg.) | Key ROI Drivers | Est. Payback |
|---|---|---|---|---|---|
| 1 | Massachusetts | $3.00–$3.80 | $0.30+/kWh | SMART payments + SRECs + high rates | 7–10 yrs |
| 2 | New York | $2.80–$3.50 | $0.24+/kWh | NY-Sun + state tax credit + SRECs + VDER | 7–10 yrs |
| 3 | New Jersey | $2.80–$3.40 | $0.19+/kWh | TRECs + full net metering + tax exemptions | 7–10 yrs |
| 4 | Hawaii | $2.80–$3.40 | $0.40+/kWh | 35% state credit + highest electricity rates in the US | 7–10 yrs |
| 5 | Maryland | $2.70–$3.20 | $0.17+/kWh | SRECs + full net metering + property tax exemption | 8–11 yrs |
| 6 | South Carolina | $2.50–$2.90 | $0.15+/kWh | 25% state tax credit + full net metering + low costs | 8–11 yrs |
| 7 | Rhode Island | $2.90–$3.50 | $0.27+/kWh | REF incentives + high rates + full net metering | 8–11 yrs |
| 8 | Connecticut | $2.90–$3.50 | $0.28+/kWh | ZREC program + high rates + full net metering | 9–12 yrs |
| 9 | Illinois | $2.70–$3.30 | $0.17+/kWh | IL Shines SRECs + full net metering | 9–12 yrs |
| 10 | Arizona | $2.30–$2.70 | $0.14+/kWh | Low cost + extreme sun = massive production | 9–12 yrs |
The pattern is clear: States that maintained robust incentive programs after the federal ITC expired are now the standout markets for residential solar. If your state offers SRECs, meaningful tax credits, or strong net metering, solar can still pay for itself in under a decade.

Get Your Free Solar Estimate →Key States: Detailed Breakdown
California: Still #1 in Installations, But the Shine Is Fading
- Cost per watt: $2.70–$3.20
- Average system cost (7 kW): $20,650
- Net metering: NEM 3.0 (export credits reduced ~75% from retail rate)
- Key incentives: SGIP battery rebates, some local utility rebates
- Payback period: 10–14 years
California remains the nation's largest solar market by total installations, but the economics have shifted. NEM 3.0, which took effect in April 2023, slashed the value of exported solar energy by roughly 75%. Homeowners who once earned $0.30/kWh for excess electricity now receive $0.05–$0.08/kWh during many hours.
The new California solar playbook: Pair panels with battery storage. By storing excess energy during the day and using it during expensive evening peak hours, homeowners can maximize self-consumption and avoid the low NEM 3.0 export rates. Battery systems add $8,000–$15,000 to upfront costs but dramatically improve long-term economics.
Without the federal ITC and with reduced net metering, California payback periods have stretched from 6–8 years (in 2023) to 10–14 years in 2026. Solar still makes financial sense for most California homeowners given the state's high electricity rates ($0.30–$0.45/kWh for many PG&E and SCE customers), but the math is tighter than it used to be.
Florida: The Sunshine State's Solar Surge
- Cost per watt: $2.40–$2.90
- Average system cost (7 kW): $18,550
- Net metering: Declining to 60% of retail rate for new systems in 2026
- Key incentives: Sales tax exemption, property tax exemption
- Payback period: 10–13 years
Florida benefits from low installation costs and dual tax exemptions that save homeowners $1,500–$2,500 on a typical system. The state has no income tax, so the expired federal ITC is less impactful for Floridians who were already unable to benefit from state income tax credits.
The main concern is net metering. Florida's net metering policy has been under attack from utilities, and 2026 brings reduced export rates — roughly 60% of retail for new interconnections. Homeowners who installed under full retail net metering are grandfathered, but new systems face lower returns on exported power.
Florida bottom line: Still one of the most affordable states for solar, but the window for maximum savings is narrowing as net metering continues to erode.
Texas: Big Solar Energy
- Cost per watt: $2.30–$2.80
- Average system cost (7 kW): $17,850
- Net metering: No statewide mandate; varies by utility
- Key incentives: Property tax exemption; utility rebates (Austin Energy, CPS Energy)
- Payback period: 10–13 years
Texas offers some of the lowest installation costs in the country, driven by a deregulated electricity market, competitive installer landscape, and low labor costs. The state has no income tax, which historically meant Texans captured less value from the federal ITC compared to residents of income-tax states.
The lack of statewide net metering is the primary drawback. Solar export policies vary wildly by utility and retail electricity provider. Some plans credit excess production at wholesale rates ($0.02–$0.04/kWh), while others offer more generous buyback programs. Homeowners in the Austin Energy and CPS Energy service areas have access to better incentives than the state average.
Texas tip: Shopping for a retail electricity plan that offers favorable solar buyback rates can improve payback by 2–3 years. Pair this with the property tax exemption and Texas becomes a strong market despite the lack of state-level solar programs.
Arizona: Maximum Sun, Shifting Policies
- Cost per watt: $2.30–$2.70
- Average system cost (7 kW): $17,500
- Net metering: Being reduced (utility-specific export rates)
- Key incentives: Residential solar energy credit ($1,000 cap), property tax exemption
- Payback period: 9–12 years
Arizona boasts some of the best solar production in the nation — a typical rooftop system generates 15–20% more energy than the same system in the Midwest. Combined with low installation costs, Arizona remains among the best states for going solar.
The challenge is policy erosion. APS and other major utilities have steadily reduced the value of net metering, replacing full retail credit with lower "resource comparison proxy" rates. The $1,000 state tax credit, while helpful, barely dents the cost of a full system.
Despite these headwinds, Arizona's sheer solar production volume and low costs keep payback periods competitive at 9–12 years.
New York: Policy Powerhouse
- Cost per watt: $2.80–$3.50
- Average system cost (7 kW): $22,050
- Net metering: VDER (Value of Distributed Energy Resources) — full retail equivalent for most residential
- Key incentives: NY-Sun rebates ($0.20–$0.40/W), state tax credit (25%, up to $5,000), SRECs, property tax exemption
- Payback period: 7–10 years
New York stands out as the best-positioned state for post-ITC solar. The combination of NY-Sun rebates, a 25% state tax credit (capped at $5,000), SREC income, property tax exemptions, and above-average electricity rates creates a compelling package.
Example New York scenario (7 kW system):
- Gross cost: $22,050
- NY-Sun rebate: -$1,400 to -$2,800
- State tax credit (25%, capped): -$5,000
- Net cost: ~$14,250–$15,650
- Annual SREC income: $200–$400
- Annual electricity savings: $1,600–$2,200
Even without the federal ITC, New York homeowners can see payback in 7–10 years thanks to layered state incentives.
Massachusetts: Expensive But Worth It
- Cost per watt: $3.00–$3.80
- Average system cost (7 kW): $23,800
- Net metering: Full retail rate
- Key incentives: SMART program (performance-based payments), SRECs, sales tax exemption
- Payback period: 7–10 years
Massachusetts is the most expensive state for solar installations, yet it consistently ranks among the best for ROI. The secret is the SMART (Solar Massachusetts Renewable Target) program, which pays homeowners a fixed rate per kWh produced over a 10-year contract period. Combined with SREC sales and some of the highest electricity rates in the continental US ($0.28–$0.35/kWh), the payback period rivals states that cost $6,000 less to install.
Massachusetts is the poster child for why "cheapest" and "best value" are different things in solar.
What Affects Solar Panel Cost?
Solar pricing is not random. Several factors combine to determine what you will actually pay.
1. Labor Rates and Market Competition
Labor accounts for roughly 10–15% of total system cost. States with higher costs of living (Massachusetts, New York, California) pay installers more, which gets passed directly to customers. States with many competing solar companies tend to have lower margins and better pricing for consumers.
2. Permitting and Interconnection Fees
Permit costs range from $100 to over $1,000 depending on your municipality. Some states have streamlined solar permitting (California's SolarAPP+ program, for example), while others still require lengthy reviews. Interconnection fees charged by utilities can add $50–$500 to connect your system to the grid.
3. Roof Type and Condition
- Standard asphalt shingle roof: Easiest and cheapest to install on
- Tile roof: Adds $500–$1,500 (tiles must be carefully removed and replaced)
- Metal standing seam roof: Can actually reduce costs (clamp-on mounting, no penetrations)
- Flat roof: Requires tilt racks, adds $500–$1,000
- Slate or wood shake: Adds $1,000–$3,000 (fragile, specialized labor needed)
If your roof needs replacement within 5–10 years, do it before or during solar installation. Removing and reinstalling panels for a future reroof costs $1,500–$4,000.
4. System Size
Larger systems cost more in total but less per watt. A 4 kW system might cost $3.20/W while a 10 kW system comes in at $2.60/W. This is because fixed costs (permitting, design, truck roll, interconnection) get spread over more panels.
5. Equipment Quality
Solar panels and inverters come in tiers:
| Tier | Panel Examples | Cost Impact | Warranty |
|---|---|---|---|
| Premium | SunPower Maxeon, REC Alpha, Panasonic | +$0.30–$0.50/W | 25–40 year product + performance |
| Mid-tier | Q Cells, Canadian Solar, LONGi | Baseline | 12–25 year product, 25 year performance |
| Budget | Various house brands, lesser-known imports | -$0.20–$0.30/W | 10–12 year product, 25 year performance |
Inverter choice matters too. String inverters ($0.10–$0.20/W) are cheaper, while microinverters ($0.30–$0.50/W) offer panel-level optimization and monitoring. Enphase microinverters dominate the US residential market.
6. Battery Storage (Optional but Increasingly Common)
Adding a home battery (Tesla Powerwall, Enphase IQ, Franklin WH, etc.) adds $8,000–$15,000 to your system cost. Batteries are increasingly popular in states with:
- Time-of-use electricity rates (California, Arizona, Hawaii)
- Reduced net metering (NEM 3.0 states)
- Frequent power outages (Florida, Texas, Louisiana)
Batteries do not usually improve ROI on their own, but they provide energy independence and backup power that many homeowners value.
How to Read a Solar Quote
A legitimate solar quote should include all of the following. If any are missing, ask why.
What Every Quote Should Show
- System size in kW (DC rating) — typically 5–12 kW for residential
- Number and model of panels — know exactly what you are getting
- Inverter type and model — string inverter, microinverters, or optimizers
- Total gross cost — the full price before any incentives
- Applicable incentives — listed individually with dollar amounts
- Net cost after incentives — what you actually pay
- Estimated annual production in kWh — based on your specific roof, shading, orientation
- Estimated annual savings — in dollars, based on your current electricity rate
- Payback period — how many years until the system pays for itself
- Warranty details — panel product warranty, performance warranty, inverter warranty, workmanship warranty
Red Flags in Solar Quotes
- "After federal tax credit" pricing — The 30% residential ITC expired on Dec 31, 2025. If a quote in 2026 still shows a federal tax credit discount, the installer is either uninformed or dishonest. Walk away.
- No line-item breakdown — You should see equipment, labor, permitting, and other costs separately.
- Guaranteed savings claims — No honest installer can guarantee specific dollar savings because electricity rates may change.
- Pressure to sign today — Reputable companies give you time to compare quotes.

Your solar quote shows the system price, but the following costs can catch homeowners off guard.
Electrical Panel Upgrade
Older homes (pre-2000) often have 100-amp or 150-amp electrical panels that cannot safely support a solar system. Upgrading to a 200-amp panel costs $1,500–$4,000 and is sometimes required by code. Some installers include this in their quote; many do not.
Roof Repairs or Replacement
As noted above, installing solar on a roof that needs replacement within a decade is a costly mistake. Budget $8,000–$15,000 for a new roof if needed, and ideally coordinate it with your solar installation to save on labor.
Tree Removal or Trimming
Shading from trees can drastically reduce solar production. If an installer recommends tree removal, expect to pay $500–$2,500 per tree depending on size and location. Professional trimming is cheaper at $200–$800 but may need to be repeated every few years.
Permit and HOA Fees
- Building permits: $100–$1,000+ depending on your municipality
- HOA review fees: $0–$500 (some HOAs charge an architectural review fee)
- Utility interconnection fees: $50–$500
Monitoring System
Most modern inverters include free monitoring via a smartphone app (Enphase, SolarEdge). Some installers charge $100–$300 for a separate monitoring gateway or subscription. Confirm this is included before signing.
Trench or Conduit Work
If your electrical panel is far from the optimal solar array location, additional conduit runs can add $500–$2,000.
DIY vs. Professional Solar Installation
The rise of DIY solar kits has made self-installation a tempting option for handy homeowners. Here is an honest comparison.
Cost Comparison
| Factor | DIY Installation | Professional Installation |
|---|---|---|
| Equipment cost (7 kW) | $8,000–$12,000 | Included in system price |
| Labor | Your time (40–80 hours) | $3,000–$5,000 (included) |
| Permitting | You handle it ($100–$500) | Installer handles it |
| Total cost | $8,500–$13,000 | $17,500–$24,500 |
| Savings vs. pro install | 40–55% | — |
The Case for DIY
- Massive cost savings — Cutting labor and overhead can save $8,000–$12,000
- Learning experience — Understanding your own energy system
- Companies like Project Solar, Signature Solar, and DIYSolarForum provide kits, design services, and support
The Case Against DIY
- No workmanship warranty — If your roof leaks, it is on you
- Permitting headaches — Many municipalities require a licensed electrician for final connections
- Voided equipment warranties — Some manufacturers will not honor panel or inverter warranties unless installed by a certified professional
- Safety risks — Working on rooftops with electrical systems is genuinely dangerous
- Incentive eligibility — Some state programs (like SRECs and SMART) may require professional installation
- Resale value — Buyer confidence is lower with DIY systems; home inspectors may flag them
Our recommendation: DIY solar can make sense for ground-mount systems on rural properties or for homeowners with genuine electrical experience. For most rooftop installations, the warranty protection, permit handling, and incentive eligibility of a professional install justify the premium.
Solar Cost Trends: Are Prices Going Up or Down?
Panel Prices Continue to Fall
The global solar module market remains oversupplied in 2026, with Chinese manufacturers producing far more panels than the world can install. This has pushed panel-only costs to historic lows — under $0.20/W at the wholesale level for standard modules.
However, panel cost is only 25–30% of your total installed system price. The rest is labor, inverters, racking, wiring, permitting, and installer overhead — costs that have not dropped as fast.
Installation Costs: Mostly Flat
Labor rates, permitting costs, and customer acquisition costs (the money installers spend on marketing to find you) have remained stubbornly flat or even increased slightly. In many states, the total installed cost per watt has declined only 3–5% since 2024, despite significant panel price drops.
The Tariff Wildcard
US tariffs on imported solar cells and modules remain a factor. Trade policy changes could increase module costs by $0.05–$0.15/W with limited notice. This is worth monitoring but should not paralyze your decision — tariff uncertainty has existed in solar for a decade.
What to Expect in 2027 and Beyond
Most industry analysts project:
- Continued slow decline in total installed costs (2–5% per year)
- No return of the federal ITC for residential solar in the near term
- Possible new state incentives as states compete for clean energy leadership
- Battery costs dropping faster than panel costs, making storage more accessible
The takeaway: Waiting for prices to drop further is a losing strategy if your electricity rates are rising 3–5% annually. Every month you wait is a month of electricity bills you could have avoided.
Frequently Asked Questions
How much do solar panels cost in 2026 without the federal tax credit?
The national average for a residential solar system in 2026 is $2.50–$3.50 per watt before incentives, or approximately $17,500–$24,500 for a typical 7 kW system. Without the federal ITC (which expired December 31, 2025), homeowners pay the full installed price minus any applicable state and local incentives. In states with strong programs like New York or Massachusetts, state incentives can reduce net costs by $5,000–$8,000.
What is the cheapest state for solar panels?
Arizona and Texas offer the lowest installation costs, with average prices of $2.30–$2.80 per watt. A 7 kW system in either state typically costs $17,000–$19,000 before incentives. However, the cheapest installation cost does not always mean the best deal — states with strong incentives and high electricity rates (like Massachusetts or New York) often have faster payback periods despite higher upfront costs.
Is solar still worth it without the federal tax credit?
For many homeowners, yes. Whether solar pencils out depends on your state's incentives, your electricity rate, and your solar production potential. In states with strong incentive programs and electricity rates above $0.15/kWh, solar typically pays for itself in 8–12 years and then produces free electricity for the remaining 15–20 years of the system's life. In states with cheap electricity, no incentives, and poor net metering, the math is much harder to justify.
How long do solar panels take to pay for themselves in 2026?
Payback periods range from 7 years (in states like Massachusetts, New York, and Hawaii with strong incentives and high electricity rates) to 18+ years (in states like Mississippi, Alabama, and West Virginia with cheap electricity and no incentives). The national average payback without the federal ITC is approximately 11–14 years.
How much do I save per month with solar panels?
Monthly savings depend entirely on your electricity rate, system size, and solar production. A 7 kW system producing 10,000 kWh/year in a state with $0.15/kWh electricity saves roughly $125/month. The same system in Massachusetts at $0.30/kWh saves $250/month. Your actual savings depend on your specific usage pattern, net metering policy, and rate structure.
Should I add a battery to my solar system?
Batteries make the most financial sense if you live in a state with:
- Time-of-use electricity rates where peak prices are much higher than off-peak
- Reduced net metering (like California's NEM 3.0) where export credits are low
- Frequent power outages where backup power has tangible value
In states with full retail net metering, batteries typically do not improve financial returns — the grid effectively acts as a free battery. However, batteries do provide energy independence and backup power that many homeowners find valuable regardless of the pure economics.
How many solar panels do I need?
The number of panels depends on your electricity usage and the wattage of each panel. A typical US household uses 10,000–11,000 kWh per year. With modern 400W panels and accounting for your location's solar resource:
- Sunny states (AZ, TX, FL): 15–18 panels (6–7 kW)
- Moderate states (NC, CO, MO): 17–20 panels (7–8 kW)
- Northern states (NY, MA, WI): 19–23 panels (8–9 kW)
Do solar panels increase home value?
Research consistently shows that solar panels increase home value by approximately $15,000–$25,000 for an average system, though the premium varies by market. Owned systems (not leased) add more value. In hot solar markets like California and Arizona, buyers actively seek solar-equipped homes. In markets where solar is less common, the premium may be smaller. Importantly, most states with property tax exemptions for solar ensure that the added home value does not increase your property taxes.
Can I negotiate solar panel prices?
Yes. Solar pricing is not fixed, and there is meaningful room for negotiation. Strategies that work:
- Get 3–5 quotes from different installers — this is the single most effective way to lower your price
- Ask about cash discounts — Many installers offer 5–10% lower prices for cash purchases vs. loans
- Mention competitor pricing — Installers will often match or beat a written quote from a competitor
- Consider timing — Q4 and Q1 tend to be slower seasons when installers may offer better pricing
- Look for group-buy programs — Solarize campaigns and community solar programs negotiate bulk discounts
