While it may seem that everything today is divided along party lines, that’s not the case when it comes to rooftop solar panels. Residential solar has strong adoption anywhere people can save money by generating electricity from the sun. Since the sun is free, and shines on Democrats and Republicans the same, that means rooftop solar panels are in every state. Some of the strongest solar states reliably vote Republican, and swing states have a strong showing, too.
In Palmetto’s experience, states across the political spectrum vote for solar with their money at fairly even rates.

Nearly 50,000 People in Red States Have Gone Solar With Palmetto
As of early 2025, more than half of Palmetto’s installations were in states that voted for President Trump in the 2024 election. That’s nearly 44,000 installations. For the nearly 23,000 systems purchased from Palmetto, average estimated annual savings were about $1,500, or $37,500 over 25 years.* Across all of the solar panel systems people bought from Palmetto in red states, that’s an estimated 25-year savings of about $850 million.
Here’s how those systems break down by states that voted Republican in 2024.
| State | Purchased systems | LightReach systems |
|---|---|---|
| Arizona | 363 | 5,651 |
| Florida | 4,359 | 7,855 |
| Georgia | 3,367 | 837 |
| Kansas | N/A | 139 |
| Michigan | 1,066 | 374 |
| Missouri | 150 | 2 |
| Nevada | N/A | 1,257 |
| North Carolina | 4,621 | 239 |

| Texas | 2,294 | 2,971 |
| Wisconsin | 358 | N/A |
| Total | 22,712 | 21,385 |
These numbers are only getting larger as more systems come online.
Of the top states for solar (including rooftop and other larger installations), many of them voted for President Trump in 2024. Texas (2nd overall), Florida (3rd), Arizona (4th), North Carolina (5th), Nevada (6th), and Georgia (7th) are all in the top ten.

The Case for Rooftop Solar
Solar and incentives supporting it are broadly popular, according to a poll conducted before the November 2024 election. The poll reported 87% of Americans and 78% of Republicans supported tax incentives for clean energy including solar.
Seventy five percent of respondents said that solar was good for the economy, 71% understood solar plus storage boosted grid reliability, and 74% said increasing solar use would save American families money.
Those numbers could be even higher for just residential solar, which doesn’t use farmland or undeveloped land. And, while utility scale solar is one of the cheapest supplies of power, the savings from rooftop solar are direct, appearing on homeowners’ electric bills. Rooftop solar has fewer perceived downsides and more apparent benefits.
Whether measured by public opinion or the number of people going solar, it’s clear rooftop panels enjoy broad support across the political spectrum, but especially in Republican-leaning areas.
