Rebates and incentives, Wyoming
A sales tax exemption and statewide net metering that pays differently by utility. The widely repeated $3,000 rebate and property tax exemption do not appear to currently exist. See your real numbers.
How it works
Step 1
Both are frequently repeated across guides but do not appear to currently exist as active, administered programs. If an installer mentions either, ask them to name the specific agency and application process.
Step 2
Investor-owned utilities like Rocky Mountain Power and Black Hills Energy generally pay full retail, but many rural cooperatives use a lower avoided-cost rate instead. This is the single most consequential number in your Wyoming solar math. Check the performance-based incentive calculator once you have it.
Step 3
Given the statute's age, ask your installer to confirm current status with the Wyoming Department of Revenue rather than assuming it's unchanged. Check your federal ITC status too, since it's a bigger factor in your overall math for 2026.
A 50% residential rebate capped at $3,000 shows up across a striking number of guides, often in strikingly similar wording that suggests one piece of content being copied rather than independently verified information. At least one detailed, recently updated source addresses this directly, stating plainly that this program has no current administering agency, meaning there's no state office actually processing applications or cutting checks for it today. Combined with the absence of any source able to name a specific agency, application process, or recent recipient, the weight of evidence points to this being an outdated program that has since lapsed, not a currently available incentive. If an installer or a guide references this rebate, ask them directly which state office administers it and how to apply, since a straight answer to that question is a reasonable test of whether the program is actually live. Before you count on any incentive, check the DSIRE database of state incentives for your state's current programs.
Several guides mention a property tax exemption for residential solar in Wyoming, but at least one detailed source describes this treatment as unsettled and states there is no confirmed statewide exemption, with actual practice varying by county. Given this, the more prudent approach is not assuming your property tax bill is protected from an increase due to solar, and instead asking your county assessor's office directly how they treat added solar value in their assessment practice. Check your federal ITC status too, since federal rules also changed for 2026 purchases. To see how a loan changes this result, run the combined loan and rebate timing tool with the same system cost.
Wyoming enacted a sales tax exemption for solar equipment under House Bill 319 in 2007, and multiple sources confirm this applies automatically at the point of sale, without a separate application. Because the statute is now nearly two decades old, at least one detailed source recommends verifying current status directly with the Wyoming Department of Revenue when you get your quote, in case sunset or renewal provisions have affected it since enactment. This is a reasonable, low-effort step given how many other Wyoming solar incentives once described in general guides turn out to no longer be active. The W.S. Section 37-16-101 through 104 has the official details behind this figure.
Wyoming law requires both investor-owned utilities and electric cooperatives to offer net metering for systems up to 25 kW under W.S. Section 37-16-101 through 104, a size cap well above what a typical residential system needs. What the statute does not standardize is the credit rate itself. Rocky Mountain Power, the state's largest utility with more than 140,000 customers, generally credits exports at the full retail rate, and Black Hills Energy's Cheyenne Light, Fuel & Power similarly offers retail-rate crediting. Many of Wyoming's roughly ten rural electric cooperatives instead use a lower avoided-cost rate for any credits purchased at the end of the year, which can meaningfully change your project's economics depending on which cooperative serves your address. Both structures typically roll credits over month to month within the year, with any remaining balance settled at the start of the following calendar year based on seasonal wholesale rates. Confirm your specific utility's crediting structure directly, since this single number does more to determine your Wyoming solar economics than any other incentive on this page. Compare the broader regional picture against a neighboring state with the Montana incentive estimator or the Colorado incentive estimator.
Your rebate total changes what a loan costs each month, and the combined loan and rebate timing tool shows that payment once you enter both figures.
Questions
No, and this is worth being direct about. A 50% rebate up to $3,000 is repeated across a number of guides, often in nearly identical wording that suggests copied content rather than independent verification. At least one detailed, recently updated source states plainly that this program has no current administering agency, meaning there is no state office actually processing applications or issuing payments for it today. Treat this rebate as defunct rather than budgeting around it, and ask any installer who mentions it to point you to the specific agency and application process.
This is not confirmed in Wyoming statute, despite being mentioned by some guides. At least one detailed source describes property tax treatment for residential solar as unsettled and states there is no confirmed statewide exemption, noting that treatment can vary by county. Given this, don't assume your property tax bill is protected from an increase due to solar; confirm directly with your county assessor's office rather than relying on a general claim of a statewide exemption.
It depends heavily on your utility. Wyoming law requires both investor-owned utilities and electric cooperatives to offer net metering for systems up to 25 kW, but it does not standardize the credit rate. Rocky Mountain Power and other investor-owned utilities generally credit exports at the full retail rate. Many rural electric cooperatives, which serve a meaningful share of the state outside city centers, instead use a lower avoided-cost rate for any credits purchased at year's end. Both structures roll credits over monthly, with any remaining balance settled at the start of the following calendar year. Confirm your specific utility's crediting structure before finalizing your project.
As of this writing, yes, but it's worth a quick confirmation given the exemption's age. Wyoming enacted a sales tax exemption for solar equipment under House Bill 319 in 2007, and it applies automatically at the point of sale without a separate application. Because the statute is now nearly two decades old and may carry sunset or renewal provisions, at least one detailed source recommends verifying current status with the Wyoming Department of Revenue at the time you get a quote, rather than assuming it remains unchanged indefinitely.
