Solar panel price forecast 2026-2030: where US prices are headed

In 50 words: US solar panel prices through 2030 will likely stay roughly flat at $2.40–$3.50 per watt installed for residential and $0.85–$1.10 per watt for utility-scale. Module commodity deflation continues at 3–5% per year, offset by labor inflation of 6–10% per year and rising domestic-content premium. This forecast covers the US solar panel price trajectory by segment, the upside and downside scenarios, and what could change the trajectory.

The era of dramatic solar panel price drops is over. From 2022 to 2024, US module prices fell more than 30%; from 2024 to 2026, prices have largely stabilized. The forecast through 2030 is for solar panel price to drift modestly — not the headline drops of the 2010s. This guide forecasts US solar panel prices by segment through 2030, with upside and downside scenarios.

Frequently asked questions

1. The 2024–2026 inflection: solar panel price stabilization

The trajectory of installed US residential solar panel prices over the last decade:

| Year | Installed $/W (US residential avg) | Notes | |---|---|---| | 2016 | $3.80 | Pre-trade-war baseline | | 2018 | $3.50 | Section 201 tariffs | | 2020 | $3.20 | Module commodity decline | | 2022 | $2.95 | IRA passed; supply chain disruptions | | 2024 | $2.85 | Stabilizing, module deflation peaks | | 2026 | $2.50–$3.50 (state-dependent) | Flat trajectory begins |

The 2024–2026 inflection is structural. Module commodity costs reached their natural floor; further price drops would require structural changes in cell, wafer, or polysilicon manufacturing that aren't on the horizon.

2. US solar panel price forecast: residential segment 2026–2030

| Year | Installed $/W (residential US avg) | YoY change | |---|---|---| | 2026 (actual baseline) | $2.85 | — | | 2027 (forecast) | $2.80 | -2% | | 2028 (forecast) | $2.75 | -2% | | 2029 (forecast) | $2.70 | -2% | | 2030 (forecast) | $2.65 | -2% |

Net residential US solar panel price change 2026 → 2030: approximately -7% (modest deflation).

The deflation comes from:

Module commodity deflation: -3% to -5% per year
Soft cost compression (SolarAPP+ adoption, installer scale): -1% to -2% per year

Offset by:

Labor wage inflation: +6% to +10% per year (the biggest counter-pressure)
Domestic-content premium: +1% to +2% per year as IRA cell-eligibility tightens

Net effect: roughly flat to slightly down. Don't wait for a dramatic drop.

3. US solar panel price forecast: commercial 2026–2030

| Year | Installed $/W (commercial US avg) | |---|---| | 2026 | $1.80 | | 2027 | $1.75 | | 2028 | $1.70 | | 2029 | $1.65 | | 2030 | $1.60 |

Commercial deflation is slightly faster than residential because soft cost is a smaller % of commercial system cost — module deflation flows through more directly.

4. US solar panel price forecast: utility-scale 2026–2030

| Year | Installed $/W (utility-scale US avg) | |---|---| | 2026 | $1.00 | | 2027 | $0.95 | | 2028 | $0.90 | | 2029 | $0.88 | | 2030 | $0.85 |

Utility-scale deflation: -15% over 2026–2030. The fastest segment because module is a bigger share of total cost (~35%) and soft cost (~15%) is smaller.

5. Module wholesale solar panel price forecast 2026–2030

| Year | US delivered $/W (TOPCon module) | |---|---| | 2026 | $0.32 | | 2027 | $0.30 | | 2028 | $0.28 | | 2029 | $0.27 | | 2030 | $0.26 |

Module wholesale solar panel price will continue dropping but at a much slower rate than 2018–2024. Domestic-content compliant US-cell modules will trade at $0.40–$0.55/W premium through 2028, narrowing as US cell capacity scales.

6. The 5 drivers of the forecast

Module commodity cost (downward pressure):

Polysilicon prices at structural lows (China oversupply)
Cell efficiency improvements continue (TOPCon → HJT → tandem)
Module manufacturing capacity expanding globally

Soft cost compression (downward pressure):

SolarAPP+ adoption growing 25–35%/year
Installer consolidation reducing customer acquisition costs
FERC Order 2023 reducing interconnection queue time

Labor inflation (upward pressure):

Solar installer labor demand outpacing skilled trades supply
6–10%/year wage inflation in installer labor markets
Particularly pronounced in California, NY, MA, and other high-wage states

Domestic-content premium (upward pressure):

US cell capacity not keeping pace with module assembly capacity
Treasury 2026 rules tightening cell-eligibility requirements
Premium for IRA-compliant modules will persist until cell gap closes (~2028)

Trade policy (uncertain):

AD/CVD on Southeast Asia modules (effective 2024, expanded 2025)
UFLPA enforcement continues at high level
IRA stability through 2032 assumed in baseline forecast

7. Upside and downside scenarios

Upside scenario (lower solar panel prices than baseline):

Chinese cell oversupply deepens in 2027–2028
US cell capacity catches up to module faster than expected, eliminating domestic-content premium
SolarAPP+ adoption hits 50%+ of US AHJs by 2028
Labor wage inflation moderates as installer training programs scale
2030 residential solar panel price: $2.30/W (-19% vs. baseline)

Downside scenario (higher solar panel prices than baseline):

IRA modifications under different administration
Trade policy escalation against Chinese solar imports (full tariffs)
Labor wage inflation accelerates to 12%+/year
Domestic-content premium widens as cell capacity expansion stalls
2030 residential solar panel price: $3.20/W (+13% vs. baseline)

Baseline is the most likely outcome (60% probability). Upside 25%, downside 15%.

8. Frequently asked questions

Will US solar panel prices drop a lot through 2030?

No. The era of dramatic drops is over. Expect modest declines of 2-3% per year for residential, faster for utility-scale. Net 2030 vs. 2026: roughly -7% for residential.

Should I wait for solar panel prices to drop before installing?

Probably not. The 30% ITC is the bigger value lever than waiting 2-3 years for a 5% price drop. Solar panel prices will be roughly flat through 2030.

What's the cheapest US solar panel will get by 2030?

Module wholesale: ~$0.26/W (TOPCon delivered to US installer). Installed residential: ~$2.30-$2.65/W depending on state. Utility-scale: ~$0.85/W.

Why don't solar panel prices keep dropping like they did 2018-2024?

Module commodity has reached its natural floor — further drops would require structural changes in cell, wafer, or polysilicon manufacturing. Labor inflation also counter-pressures soft cost reductions.

What's the biggest risk to the solar panel price forecast?

US labor wage inflation in the installer market. Rates of 6-10%/year are baked into baseline; higher could push residential solar panel prices up.

Could the IRA repeal change the solar panel price forecast dramatically?

Yes — IRA repeal would eliminate the 30% ITC, 10% domestic-content bonus, and 45X manufacturing credit. Effective installed solar panel prices to homeowners would rise 30-40%. Baseline assumes IRA stays in force.

When is the best time to install solar panels in the US?

2026-2027 is good — the 30% ITC is at full value through 2032, but state incentives can change without notice. Don't wait for hardware deflation; act on incentive availability.
