Solar panel installation cost
A DOE representative 8 kW residential PV-only system has a modelled low of $22,240.00 (2024 USD) and a typical of $23,600.00 (2024 USD). DOE did not publish a high installed bound, so none is shown.
Source year. Based on the DOE / NREL photovoltaic system cost benchmark (Q1 2025 release, 2024 dollars).
Geographic scope. United States national modelled benchmark.
Model scope. National PV-only residential benchmark. Owner subsidies are excluded. Soft-cost and hardware mix follow the DOE table, not a named installer.
Important limitation. These are 2024-dollar national benchmarks, not what a contractor would bid in your city today.

Benchmark estimator
Results are modelled 2024 USD benchmarks, not a contractor quote.
Modelled benchmark: Low $22,240.00 (2024 USD); typical $23,600.00 (2024 USD)
Typical result $23,600.00 (2024 USD)
What this estimate includes
- DOE market-price and minimum-sustainable-price dollars per watt
- DOE representative 8 kWdc size
- PV-only residential scope
What moves the number
- System size in kilowatts
- Whether you use the DOE typical or low dollars-per-watt rate
- Incentives, which this page excludes
Methodology and sources
- The certified unit rates are copied from DOE Table 2 PV-only residential MSP and MMP.
- The 8 kW total is those rates times 8,000 watts.
- Other sizes in the estimator are your kilowatts times the same certified 2024 rates. Size is your input.
- No inflation adjustment to 2026 is applied.
Primary source: Q1-2025 Solar Photovoltaic System Cost Benchmarks.
Limitations
- 2024$ DOE PV-only residential benchmark, not a 2026 installer quote.
- HIGH installed bound is unpublished and is not invented.
- Owner subsidies excluded.
Questions this evidence can answer
Why is there no high number?
DOE Table 2 does not publish a high installed-cost bound for this series. HomeCostMage does not invent one.
Does this include the tax credit?
No. The certified DOE note excludes owner subsidies. Subtracting a credit here would be a different, uncertified calculation.
