Solar panels are one of the biggest home upgrades you can make, so the first question is always the same: how much does it actually cost? The short answer for 2026 is that a typical home solar system runs roughly $15,000 to $25,000 installed, and in 2026 that is close to what you actually pay: the 30% federal tax credit expired on 31 December 2025, so a cash or loan purchase gets no federal credit. The real number depends on your system size, your state, and your electric bill. Here is the full breakdown, plus a free calculator to estimate your own cost and savings.
Quick Answer: Average Solar Panel Cost in 2026
| System size | Best for | Installed cost | Federal credit in 2026 |
|---|---|---|---|
| 5 kW | Smaller homes / low bills | ~$15,000 | $0 (expired) |
| 7 kW | Average U.S. home | ~$21,000 | $0 (expired) |
| 10 kW | Larger homes / high bills | ~$30,000 | $0 (expired) |
These use a national average of about $3.00 per watt installed. Your price per watt can be lower or higher depending on your installer, equipment, and state.
Solar Panel Cost Calculator: Estimate Your System
Move the slider to your average monthly electric bill and pick your state. The estimator sizes a system to cover your usage, prices it at about $3.00 per watt installed, and shows payback and 25-year savings (assuming electricity prices rise 3% a year) with no federal credit.
Use the calculator above to estimate your own system size, cost, and 25-year savings based on your bill and state.
What Actually Drives the Cost
- System size (kW). The biggest factor. A bigger electric bill needs more panels to offset it.
- Your state and local rates. States with high electricity prices pay off faster.
- Equipment. Premium panels and microinverters cost more but can produce more.
- Roof complexity. Steep, shaded, or multi-section roofs add labor.
- Battery storage. Adding a home battery typically adds $10,000 to $20,000.
Solar Panel Cost Breakdown: Where the Money Goes
An installed price is more than panels. Installers and the cost benchmarks from the Department of Energy's national lab (NREL) split it into hardware and "soft costs":
| Cost component | What it covers |
|---|---|
| Solar panels (modules) | The panels themselves |
| Inverter(s) | A string inverter, or microinverters / optimizers, that turn the panels' DC into household AC power |
| Racking and electrical (balance of system) | Mounts, rails, wiring, disconnects and any main-panel upgrade |
| Installation labor | Crew time on the roof and the electrical tie-in |
| Permitting, inspection and interconnection | Local permit fees, inspections and your utility's approval to connect |
| Sales, design and overhead | Customer acquisition, system design, warranty reserves and the installer's margin |
For home systems the soft costs (labor, permitting, sales and overhead) are a bigger share of the price than on large commercial or utility-scale projects, which is why two quotes for the same panels can differ by thousands. When you compare quotes, ask each installer for the price per watt, the exact panel and inverter models, and whether a main-panel upgrade is included.
The 30% Federal Tax Credit Has Expired
Through 2025, the federal solar tax credit let homeowners claim 30% of the system cost back on their taxes - about $6,300 on a $21,000 system. That is over. The One Big Beautiful Bill, signed 4 July 2025, ended the Section 25D residential credit for any expenditure made after 31 December 2025. Buy with cash or a loan in 2026 and you get no federal tax credit. The one federal credit still touching residential solar is Section 48E, claimed by the company that owns a leased or PPA system - not by you - and it runs through the end of 2027. Full detail: what changed and what is left.
State Incentives Stack on Top
Many states add rebates, tax exemptions, and SREC payments. The strongest 2026 programs: New Jersey, New York, Massachusetts, California. Two common questions: what a Pennsylvania SREC pays and whether New Jersey has a solar tax credit. Full list: Solar Incentives by State (2026).
Is Solar Worth It at These Prices?
For most homeowners with a bill above about $120, yes. Typical payback is 8 to 14 years without the federal credit, and as short as 6 to 9 years in high-rate states with strong incentives, then the electricity is essentially free for the rest of the panels' life. Over 25 years the average system saves $20,000 to $40,000+. Full breakdown: Is Solar Worth It in 2026?

Frequently Asked Questions
How much do solar panels cost for an average home in 2026?
About $21,000 installed for a typical 7 kW system. With the federal credit expired, that is close to your real out-of-pocket cost unless your state or utility has its own incentive.
How much can I save with solar?
Most homeowners save $20,000 to $40,000 or more over 25 years, with a payback of roughly 8 to 14 years depending on your state.
Is the 30% federal tax credit still available?
No. Section 25D expired on 31 December 2025. A 2026 cash or loan purchase receives no federal tax credit. Reject any quote that still shows one.
How do I estimate solar panel cost for my home?
Multiply the system size you need (in kW) by the local price per watt. A 7 kW system at about $3.00 per watt is about $21,000. The solar panel cost calculator above does this from your bill and state and shows the payback. A quote based on your own roof is the final number.
Does the cost include a battery?
No. Standard prices are panels and installation only. A battery typically adds $10,000 to $20,000 before incentives.
