How Much Does Solar Installation Cost?
When people ask “how much does solar cost,” they usually mean the installed price - equipment plus the labor and paperwork to put it on your roof. Here’s what that costs in 2026 and where the money actually goes.
The headline numbers (2026)
| Metric | Typical range |
|---|---|
| Installed cost per watt | $2.50-$3.50 (avg ≈ $2.75) |
| Typical home system (~7 kW) | $15,000-$25,000 |
| Larger system (~12 kW) | ~$29,000-$40,000 |

Compare quotes on price per watt - it normalizes for system size. $2.75/W × 7,000 W ≈ $19,250.
Where the money goes (it’s not mostly panels)
A common surprise: hardware is often less than half the total. The rest is the installation itself:
- Equipment - panels, inverter, racking
- Labor - the crew doing the mounting and wiring
- Permitting & inspection - fees + admin (see permits)
- Design, engineering, sales, and overhead (“soft costs”)
This is why two quotes for identical panels can differ a lot - the difference is labor and overhead, not the gear.
What drives your price up or down
- System size - bigger total, but often lower price per watt.
- Roof type & complexity - tile, steep, or multi-face roofs add labor; see roof types.
- Electrical work - a main-panel upgrade or long wire runs add cost (see electrical basics).
- Add-ons - a battery or EV charger increases the total.
- Location - local labor rates and permit fees vary widely.
A note on incentives
Installed price is before incentives. The federal 30% purchase credit expired at the end of 2025, so a 2026 purchase doesn’t get it - but state/utility incentives may still apply, and lease/PPA financing carries a federal benefit claimed by the provider. Check your state’s programs.
Getting an accurate number
- Get at least three itemized quotes - see how to choose an installer.
- Make sure each quote lists price per watt, equipment models, and whether permits, inspection, and any electrical upgrades are included.
- Watch for vague “adders” added later.
Bottom line
Budget about $2.50-$3.50 per watt - roughly $15,000-$25,000 for a typical home system installed, before incentives. Remember that labor, permitting, and overhead make up a large share, so compare quotes on price per watt with the same scope. Then vet who’s doing the work: how to choose a solar installer.
