How Much Do Solar Panels Cost? Prices, Costs and What You Get
Quick Answer
In 2026, solar panels cost roughly $2.50–$3.50 per watt installed in the US, which puts a typical 6–8 kW home system at about $15,000–$28,000 before any incentives. That price covers the panels, inverter, mounting, wiring, permits and labour, and it varies with your roof, location and equipment. The federal 30% homeowner tax credit ended for systems completed after 31 December 2025, so check state, local and utility incentives, which differ widely.
Key Takeaways
- Solar panels cost about $2.50–$3.50 per watt installed; the panels themselves are only part of that.
- A typical 6 kW system is about $15,000–$21,000 and an 8 kW system about $20,000–$28,000 before incentives.
- The federal homeowner credit ended for systems completed after 31 December 2025; state and utility incentives vary.
- Roof complexity, battery storage and installer pricing change what solar panels cost far more than home size.
- Get at least three written quotes and compare them by cost per watt, not total price.
How Much Do Solar Panels Cost?
The simplest way to compare quotes is cost per watt: the total price divided by the system's size in watts. Most residential quotes in 2026 fall between $2.50 and $3.50 per watt. We do not sell rooftop solar panels or installation, so this guide explains the pricing and links the small solar gadgets we do stock. For background, see our guides to the best solar panels, how solar panels work and the solar light buying guide.
What Solar Panels Cost by System Size
| System size | Typical installed cost | Typical fit |
|---|---|---|
| 6 kW | $15,000–$21,000 | Smaller home, lower electricity use |
| 8 kW | $20,000–$28,000 | Average home |
| 10 kW | $25,000–$35,000 | Larger home, or one with an electric vehicle |
| 12 kW | $30,000–$42,000 | High use, pool or several EVs |
These are typical ranges before incentives at roughly $3 per watt. Your quote may sit above or below them. A price above about $3.50 per watt on a simple roof is a reason to get another quote.
What Is Included in the Price
| Part of the bill | What it covers |
|---|---|
| Panels | The photovoltaic modules, a minority of the total |
| Inverter | Converts DC to usable AC; microinverters cost more than string inverters |
| Mounting and wiring | Racking, cabling, safety shut-offs |
| Labour and permits | Installation, inspection and utility connection |
| Sales and overhead | Design, customer acquisition and warranties |
| Optional battery | Adds thousands of dollars; separate from panel cost |
What Changes What Solar Panels Cost
- System size: bigger systems cost more in total but often less per watt.
- Roof type and pitch: complex or steep roofs add labour and mounting cost.
- Equipment grade: premium panels and microinverters raise the price.
- Location: labour rates, permits and local rules vary by state.
- Battery storage: a home battery can add $10,000 or more.
- Financing: loans add interest; leases and power purchase agreements change who owns the system.
Incentives and Payback
Incentives change what solar panels cost you in practice. The federal 30% homeowner credit (Section 25D) ended for systems completed after 31 December 2025, so most homeowners now pay full price unless state, local or utility programmes apply. These include rebates, net metering and property tax breaks, and they change often, so check current rules before signing. Payback depends on your electricity rate, sunshine, system cost and how long you stay; commonly quoted estimates run from roughly 8 to 14 years, but your figure could be shorter or longer. This is general information, not financial advice, so consider speaking to a qualified adviser.
What to Expect at Each Level
| Budget | What solar panels cost at this level buys | Trade-offs |
|---|---|---|
| Under $15,000 | A small 4–5 kW system or a very efficient quote | May not cover all your usage |
| $15,000–$25,000 | A typical 6–8 kW system with standard equipment | Payback depends on rates and incentives |
| $25,000–$40,000 | A larger 10–12 kW system or premium equipment | Longer payback unless usage is high |
| $35,000+ with battery | Solar plus storage for backup power | Battery cost rarely pays back quickly |
Safety and Buying Notes
Before you sign, get what solar panels cost in writing.
- Use licensed installers; solar involves roof work and high-voltage electrical connections that should not be DIY.
- Get at least three written quotes with equipment lists and cost per watt.
- Check warranties on panels, inverters and workmanship, and ask who services the system.
- Be wary of high-pressure sales, large upfront payments and promises of guaranteed savings.
- Confirm permits, utility connection approval and your roof's condition before installing.
Summary
Solar panels cost about $2.50–$3.50 per watt installed, or roughly $15,000–$28,000 for a typical home system before incentives. Because the federal homeowner credit has ended, compare quotes by cost per watt, check state and utility incentives, and ask for payback figures based on your own bills. Knowing what solar panels cost, and what you get for the money, lets you judge quotes with confidence.

Frequently Asked Questions
How much do solar panels cost for an average house?
About $15,000–$28,000 before incentives for a typical 6–8 kW system, depending on roof, location and equipment.
Is there still a federal tax credit for solar panels?
Not for homeowners buying a system completed after 31 December 2025. State, local and utility incentives may still apply, so check current rules.
Do solar panels cost less per watt for bigger systems?
Often yes, because fixed costs such as design, permits and inverters are spread over more watts.
How long do solar panels last?
Most carry 25-year performance warranties, and many keep producing for longer, though output declines slowly each year.
Should I add a battery?
Only if you want backup power or have time-of-use rates that make it worthwhile. A battery adds substantial cost and rarely pays back quickly.
