What Did a 2016 Solar Installation Cost?
In 2016, the average U.S. homeowner paid between $10,000 and $15,000 for a 5‑kilowatt (kW) residential solar system. That figure included panels, inverter, mounting hardware, labor, permitting, and inspection. After federal tax credits, the net cost dropped to roughly $8,000–$11,000. These numbers varied by region, roof type, and installer, but the range above represents the typical out‑of‑pocket expense for a full system.

Component Breakdown of a 2016 Installation
Below is a concise table showing the main cost drivers for a 5‑kW system in 2016.
| Component | Average Cost 2016 | Source Type |
|---|---|---|
| Solar Panels (10‑12 modules) | $5,000–$6,500 | Industry Survey |
| Inverter (string or micro‑inverter) | $800–$1,200 | Industry Survey |
| Mounting & racking hardware | $600–$900 | Industry Survey |
| Installation labor | $1,200–$2,000 | Industry Survey |
| Permits & inspection fees | $200–$400 | Local Government Data |
| Contingency/overhead | $1,000–$1,500 | Industry Survey |
How Tax Credits Reduced the Price
The federal Investment Tax Credit (ITC) in 2016 covered 30% of the total cost, effectively lowering the net price by $3,000–$4,500 for most installations. States with additional rebates could bring the final cost below $8,000 for many homeowners.
Price Trends Since 2016
Solar panel prices fell by roughly 30% from 2016 to 2023 due to manufacturing efficiencies, economies of scale, and policy support. Installation labor costs have risen modestly (~2% annually) because of higher wages and supply chain adjustments. Net result: a 5‑kW system today averages $10,000–$13,000 before credits, dropping to $7,000–$9,000 after the 30% ITC.
Regional Variations
- West Coast: Higher labor rates keep prices 10–15% above the national average.
- Midwest: Lower permitting fees and abundant installers keep costs near the lower end.
- South: Sunlight abundance and lower roof installation complexity reduce average costs.
What the 2016 Cost Means Today
Understanding 2016 prices helps homeowners gauge the value of modern systems. The technology has improved—higher efficiency panels and smarter inverters—yet the price per watt has dropped by about 50% since then. If you're comparing a 2016 system to a new one, factor in the 2016 cost as a baseline for ROI calculations, especially when evaluating long‑term savings and financing options.
Key Takeaways
- 2016 average cost: $10,000–$15,000 before credits.
- Federal ITC reduced net cost to $8,000–$11,000.
- Component costs: panels (~$5–$6.5k), inverter ($0.8–1.2k), labor ($1.2–2k).
- Prices have fallen ~30% for panels and ~10% for labor since 2016.
- Regional differences still affect final pricing.
