Solar installed-price trends

Median $/W (pre-incentive, nominal) across 2,988,711 priced systems — the reference series for what US homeowners actually paid.

At a glance

The median installed price of a recorded US solar system was $4.33/W in 2025, before incentives — about $33,774 for the median 7.8 kW system. That is 50% below the 2000 peak of $8.66/W. Across all 2,988,711 priced systems the median is $4.23/W.

Medians cover distributed (rooftop and commercial) systems from sources that report an installed price, within the 0.3–25 $/W sanity band; states with fewer than 100 priced systems are not listed. Third-party appraised values inflate some program prices — see methodology.

How have US solar prices changed?

The highest median was $8.66/W in 2000, the first year in the series and the lowest $3.83/W in 2019. Over the last decade the median went from $4.50/W (2015) to $4.33/W (2025), a drop of 4%. The median system grew from 6.1 kW to 7.8 kW over the same years. Figures are nominal dollars as reported to state programs, not adjusted for inflation.

Which states have the lowest solar prices?

Of the 23 states with at least 100 priced systems, the lowest all-years medians are in New Hampshire ($3.40/W), Washington ($3.45/W) and Wisconsin ($3.52/W). The highest is Illinois at $6.25/W, about 48% above the national median. State medians mix every year a state has records for, so a state whose records are mostly older carries a higher median.

Frequently asked questions

How much does solar cost per watt right now?

In 2025, the median recorded installed price was $4.33/W pre-incentive (median system 7.8 kW ≈ $33,774). State medians range from $3.40/W (New Hampshire) to $6.25/W (Illinois).

Have solar prices gone down?

Yes — the recorded median peaked at $8.66/W in 2000 and stands at $4.33/W in 2025. Note these are nominal, pre-incentive prices as reported to state programs.

Which state has the cheapest solar?

New Hampshire, with a median installed price of $3.40/W across all recorded years, among states with at least 100 priced systems. Illinois is the highest at $6.25/W.

What does the installed price include?

The total installed price reported for each system to its state incentive program or permit record, before any tax credit or rebate, divided by its DC capacity. Prices outside a 0.3–25 $/W sanity band are excluded.
