Solar panel prices have fallen ~40% since 2020, but the rate of decline has slowed dramatically in 2025–2026. Here's what homeowners should know about current pricing trends.
The pricing trend (2020–2026)
- 2020: $2.80/W installed (residential)
- 2022: $2.50/W (supply chain crisis slowed decline)
- 2024: $2.20/W
- 2026: $2.05/W (current)
The 2024–2026 period saw only ~7% decline — much slower than the 2020–2022 period. The reason: panel prices have hit their material cost floor. The remaining cost is labor, permitting, and installer margin — which don't decline with technology.
What's actually getting cheaper
While panel prices have stabilized, other components continue to fall:
- LFP battery cells: Down 28% in 2025, expected to fall another 10–15% in 2026
- Inverters: Down 8–12% as Chinese manufacturers (Huawei, GoodWe) compete on price
- Racking and BOS: Stable — commodity aluminum and steel
What this means for homeowners
Don't wait for solar panel prices to drop further — they're not going to. The math is best when you bundle solar + storage today, claim the 30% federal credit, and lock in current low battery pricing. See our solar plus storage guide.
