LindaIf you’ve been thinking about going solar, 2025 might just be your year. Solar panel prices have dropped dramatically over the past decade, but installation costs still vary wildly depending on where you live. That’s why we’ve done the research and rounded up the 10 cheapest states for solar panel installation in 2025 — so you know exactly where your dollar stretches the furthest.
And yes, there are some surprising states on this list (hint: it’s not just the sunny southwest).
Why Solar Panel Installation Costs Vary Across States
If solar panels were like a flat-priced phone plan, this article wouldn’t exist. But in reality, installation costs change from state to state — and it’s not just about how sunny the weather is.
Factors Affecting Solar Installation Prices
The cost of installing a solar system depends on a few big factors.
Labor Costs & Local Wages
Some states have higher wages for electricians and roofers, which can push up installation prices. Labor often makes up 25–35% of the total system cost.
State Incentives and Rebates
Generous solar financing incentives or state rebates can slash thousands off your bill. Places with big incentives tend to have more affordable net prices, even if the upfront cost is higher.
Electricity Rates and Demand
In states where electricity is expensive, people are more motivated to go solar — which creates a competitive installer market and drives prices down.
