Solar panels are cheaper to install than ever — but the price still varies widely depending on your system size, location, and equipment. In 2026 the math also changed in one important way: the federal tax credit for purchased home systems expired at the end of 2025. This guide breaks down exactly what solar panel installation costs in 2026, where every dollar goes, how prices differ by state, and how to keep your costs down.
Quick Answer: How Much Does Solar Panel Installation Cost?
In 2026, home solar typically costs $2–$3 per watt installed — roughly $14,000–$28,000 for a normal system, with the average 7 kW system around $19,500 before any incentives. DIY systems can run $0.80–$1.40 per watt. Note: the 30% federal tax credit for purchased systems ended Dec 31, 2025 — only leases and PPAs can still claim it.
iKey Takeaways
- Average cost: ~$2.82 per watt nationally; $2–$3/watt typical.
- Typical system: a 7 kW install averages about $19,500 before incentives.
- Panels are ~30% of the cost; the rest is inverter, hardware, labor & soft costs.
- 2026 change: the federal tax credit for purchased systems expired end of 2025.
- Batteries add roughly $8,000–$15,000.
- Save by getting 3+ quotes, right-sizing, and capturing state/utility incentives.
How Much Do Solar Panels Cost in 2026?
The single biggest factor in your price is system size, measured in kilowatts (kW). Bigger systems cost more in total but often a little less per watt. At a national average near $2.82 per watt, here’s what typical home systems cost before any incentives.
5 kW~$14,000Small / efficient homes
7 kW (average)~$19,500Average U.S. home
10 kW~$28,000Large homes
13 kW~$36,000Very large homes / EV / pool

Not sure what size you need? Our guide on how many solar panels you need helps you size the system first — which is the real driver of your total cost.
Solar Cost Per Watt Explained
The fairest way to compare solar quotes is cost per watt — the total price divided by the system’s wattage. It strips out system size so you can compare apples to apples. A lower number means better value. Here’s the 2026 landscape.
National average~$2.82
Competitive / low end~$2.00
Complex roof / high-cost areas~$3.50+
Sunbelt example (Florida)~$2.20
DIY (equipment only)~$0.80–$1.40
If a quote comes in above $3.00/watt without a clear reason (steep roof, premium panels, battery), it’s worth getting more bids.
What’s Included: Cost Breakdown by Component
It surprises most people that the panels are only about a third of the price. The rest goes to the inverter, mounting hardware, electrical work, permits, and the installer’s design, sales, and overhead — the so-called “soft costs.”

Design, sales & overhead~30%~$5,850
This is exactly why DIY can save so much: handling design, sales, and labor yourself removes most of the soft costs. See our full step-by-step installation guide for the DIY route.
Solar Panel Cost by State
Where you live has a big effect on price. Labor rates, permitting fees, competition among installers, and local demand all push the cost per watt up or down. Sunbelt states tend to be cheaper per watt and pay back faster; high-cost regions like Hawaii sit at the top. Here are representative 2026 figures.
Florida~$2.20~$15,400
Arizona~$2.40~$16,800
Texas~$2.50~$17,500
National average~$2.82~$19,700
California~$2.90~$20,300
New York~$3.00~$21,000
Hawaii~$3.20+~$22,400+

The 2026 Tax-Credit Change: What It Means for Your Cost
This is the most important cost update for 2026, and many websites still have it wrong. For over a decade, a 30% federal tax credit slashed the net price of home solar. That changed under the One Big Beautiful Bill Act, signed in July 2025.
The 30% federal credit expired for purchases (Dec 31, 2025)
If you buy a solar system in 2026, you can no longer claim the 30% federal residential tax credit (Section 25D) — it expired on December 31, 2025 and did not step down. The big exception: solar leases and PPAs can still capture the 30% credit (Section 48E) through 2027, because the leasing company claims it and passes the savings to you. State, local, and utility incentives plus net metering also remain.
In practice, this means a homeowner buying outright in 2026 pays closer to the full sticker price, while a lease or PPA can still effectively access the 30% discount. It makes comparing financing options (below) more important than ever. The incentives that do remain are summarized here.
Federal credit — purchased system (25D)Expired Dec 31, 2025
Federal credit — lease / PPA (48E)Still ~30% through 2027
State tax credits / rebatesAvailable in many states
Net meteringStill offered (varies by utility)
SRECsSelect states only
Property & sales tax exemptionsCommon in many states
Local utility rebatesCheck your utility
Tax rules change and vary by location. Confirm current programs (the U.S. DSIRE database and IRS guidance) before purchasing.
Battery Storage Cost
A solar battery isn’t required, but it’s the most popular add-on — it stores daytime power for night use and keeps the lights on during outages. It’s also the biggest single cost extra. Expect to add roughly $8,000–$15,000 for a typical home battery.
Single mid-range battery~10 kWh~$8,000–$12,000
Premium battery (e.g. Powerwall-class)~13.5 kWh~$10,000–$15,000
Whole-home backup (2+ batteries)~27+ kWh~$20,000–$30,000
If your main goal is lower bills (not backup), you may not need a battery at all — net metering lets the grid act as your “battery” for free where it’s available.
DIY vs Professional Installation Cost
Doing it yourself is the single biggest way to cut cost, because it removes labor and the installer’s soft costs — roughly half the total. The trade-off is the time, skill, permitting, and risk you take on.
Cost per watt~$0.80–$1.40~$2.50–$3.00
Total for a 7 kW system~$7,000–$10,000~$17,500–$21,000
What you handleEverything (design, permits, wiring)Nothing — turnkey
Risk & warrantyHigher risk; limited warrantyLow risk; full warranty
Lease/PPA 30% creditNot applicable (you own it)Available via lease/PPA
For most homeowners a professional install is worth it for the warranty and peace of mind; confident DIYers with simpler roofs can save thousands. Our solar installation guide walks through the DIY process step by step.
Financing: Cash, Loan, Lease or PPA?
How you pay matters more in 2026 than it used to — because the financing route now decides whether you can still access the 30% credit. Here’s how the four options compare.
CashFull priceYesNo (25D expired)Lowest lifetime cost
Solar loan$0–lowYesNoOwning with no big upfront
Lease$0NoYes (leasing co passes savings)Low effort + capturing the credit
PPA$0NoYes (provider)Paying only for power produced
Buying with cash or a loan still gives the best long-term value (you own the system and all its savings), but a lease or PPA is now the only way for most homeowners to benefit from the 30% credit — worth running the numbers both ways.
Is Solar Still Worth It in 2026? Payback and Savings
Yes — even without the federal credit for purchases, solar still pays off for most homes; the payback period is simply a little longer than before. Over a 25-year lifespan, a typical system saves $20,000–$50,000+ in avoided electricity costs and shields you from rising utility rates. The payback timeline depends on how you pay, your local rates, and your sun.

Illustrative 2026 payback ranges. Cash purchases pay back a bit slower now that the 30% federal credit has expired for owned systems; leases/PPAs that still capture the credit pay back fastest.
The takeaway: solar is still a strong investment, but in 2026 the financing choice matters more. If maximizing return is your goal, compare a cash/loan purchase (you own everything) against a lease or PPA (which can still capture the 30% credit) before deciding.
How to Lower Your Solar Installation Cost
A few smart moves can cut thousands off your price:
Get at least 3 quotesPer-watt prices vary widely between installers.
Right-size the systemDon’t pay for more panels than your usage needs.
Compare cash vs lease/PPAA lease/PPA can still capture the 30% credit in 2026.
Choose standard panelsPremium panels rarely pay off unless roof space is tight.
Stack state & utility incentivesLocal rebates and net metering still reduce net cost.
Install in the off-seasonInstallers may discount during slower months.
DIY part of the workRemoving labor/soft costs can halve the price.
Right-sizing is the highest-leverage step — start with how many solar panels you actually need so you don’t overpay for capacity you won’t use.
Frequently Asked Questions
In 2026, home solar typically costs $2–3 per watt installed — about $14,000–$28,000 for a normal system, with the average 7 kW install around $19,500 before incentives. DIY systems run $0.80–$1.40 per watt. Your exact price depends on system size, location, equipment, and whether you add battery storage.The U.S. national average is about $2.82 per watt installed. Competitive markets can hit ~$2.00/watt, while complex roofs or high-cost areas (like Hawaii) run $3.50+. DIY equipment-only costs are roughly $0.80–$1.40 per watt. Cost per watt is the best way to compare quotes fairly.Not for purchased systems. The 30% federal residential tax credit (Section 25D) expired on December 31, 2025. However, solar leases and PPAs can still capture the 30% credit (Section 48E) through 2027, and many state, local, and utility incentives plus net metering remain available.Cost depends on electricity use, not floor area, but a typical 2,000 sq ft home needs about a 7–9 kW system — roughly $19,500–$25,000 before incentives at the national average. Pull your kWh usage from your bill for a precise estimate rather than going by square footage.Adding a home battery typically increases the total by $8,000–$15,000 for a single unit, or $20,000–$30,000 for whole-home backup. So a 7 kW system with one battery often lands around $27,000–$34,000 before incentives. A battery isn’t required if your goal is just lower bills with net metering.Yes, for most homes. Even without the federal purchase credit in 2026, a typical system pays back in about 9–14 years (faster with a lease/PPA) and then delivers 10+ more years of low-cost power, saving $20,000–$50,000+ over its 25-year lifespan.The panels are only about 30% of the price. The rest goes to the inverter, mounting hardware, wiring, labor, permits, and the installer’s design, sales, and overhead — the ‘soft costs.’ These soft costs are also why DIY installation can cut the total roughly in half.A 10 kW system costs roughly $28,000 before incentives at the U.S. average of ~$2.82/watt, though it ranges from about $22,000 to $35,000 depending on your state, equipment, and roof complexity. A 10 kW system suits larger homes using 12,000–15,000 kWh per year.Yes — significantly. DIY runs about $0.80–$1.40 per watt versus $2.50–$3.00 for a professional, so a 7 kW system might cost $7,000–$10,000 DIY versus $17,500–$21,000 installed. The trade-offs are the time, skill, permitting, and risk you take on, plus a more limited warranty.A typical home saves $20,000–$50,000+ in electricity costs over a 25-year system life, often more as utility rates rise. Annual savings depend on your electricity price, sunlight, and system size; sunnier areas with high power rates save the most.For a cash purchase in 2026 (without the expired federal credit), payback is typically 9–14 years depending on your sun and electricity rates. A lease or PPA that still captures the 30% credit can pay back in around 8 years. After payback, the electricity is essentially free.Watch for a few extras: an electrical-panel upgrade (if yours is older), permit and inspection fees, potential roof reinforcement or re-roofing, inverter replacement after 10–15 years, and battery costs if you want backup. A detailed written quote should list all of these up front.Conclusion: Budgeting for Solar in 2026
Solar panel installation in 2026 typically costs $2–$3 per watt — about $14,000–$28,000 for a normal home system, averaging near $19,500 for a 7 kW install. The biggest change this year is that the 30% federal tax credit ended for purchased systems, so how you finance the project now directly affects your bottom line. Even so, with 25-year savings of $20,000–$50,000+, solar remains a strong investment for most homes.
The bottom line
Budget around $2.82/watt (national average) — roughly $19,500 for a typical 7 kW system before incentives. Get at least three quotes, right-size to your actual usage, and compare buying (best long-term value) against a lease/PPA (the only route that still captures the 30% credit in 2026).
