For years, a lot of homeowners counted on the federal Residential Clean Energy Credit (often called the 25D credit) to take some of the sting out of solar purchases. That credit is gone for new installs. The IRS Residential Clean Energy Credit page says the credit is not available for property placed in service after December 31, 2025.
That's the bad news. The good news is that some states have their own solar programs, and a few of them have wording that may fit a solar-powered attic fan, shed fan or shipping container fan. We went through the official state laws and tax instructions ourselves, and here's what we found. One state names solar powered fans outright. The others are "may qualify," and we'll explain why.
Quick summary
| State | Program | Amount | Home | Shed | Shipping container |
|---|---|---|---|---|---|
| South Carolina | Solar Energy Credit (S.C. Code 12-6-3587) | 25% of purchase and installation, up to the lesser of $3,500 per facility or 50% of your tax per year | Qualifies | Qualifies (any building or structure you own) | Likely, if you own it and it's in SC |
| Arizona | Credit for Solar Energy Devices (A.R.S. 43-1083, Form 310) | 25% of cost, up to $1,000 per residence | May qualify | Unclear (residence only) | Unclear at home; not for business use |
| Arizona | Solar energy device sales tax deduction (A.R.S. 42-5061(M)) | State sales tax deducted on qualifying sales | May qualify | May qualify | May qualify |
| Florida | Renewable energy source device property tax exemption (Fla. Stat. 193.624) | Added value excluded from property assessment (see statute) | May qualify | May qualify | Unclear |
| Massachusetts | Residential renewable energy credit (830 CMR 62.6.1) | 15% of net cost, up to $1,000 | May qualify | Unclear (principal residence only) | Unclear at home; not for business use |
South Carolina: the clearest yes
South Carolina's Solar Energy Credit is the strongest option we found. The state Department of Revenue's Revenue Ruling #24-2 includes a chart of purchases that qualify, and under "Air cooling" it lists "solar powered fans."
The credit is 25% of the cost of buying and installing the system. In any tax year it's limited to the lesser of $3,500 per facility or 50% of your South Carolina tax, and unused credit can carry forward for up to 10 years.
Here's the part shed owners will like. The ruling says "A facility is any building, structure, or property located in the state and owned by the taxpayer, including residences, properties rented out to third parties, or business properties." So a solar fan on your home or your detached shed fits. A shipping container you own in South Carolina is likely covered too, since it's a structure, though the ruling doesn't mention containers by name. Systems that aren't tied to the power grid, like our fans, come with one extra step: you certify that the system meets safety standards, has its permits and passed final inspection.
Arizona: two programs that may qualify
The income tax credit. Arizona's Credit for Solar Energy Devices (A.R.S. 43-1083) is 25% of the cost of the device, including installation, up to $1,000 per residence. The 2025 Form 310 instructions list fans among items that don't qualify, but with an important exception: "Fans - ceiling, window, attic, interior, etc., unless they are manufactured specifically for photovoltaic applications." Solar Blaster fans are built to run off their own solar panel, so they may fit that exception. Arizona hasn't said so in writing for our products, so treat it as a "may qualify."
This credit is for a device installed in your residence. Arizona's definition in A.R.S. 44-1761 covers systems that serve a residential dwelling and leaves out systems on commercial structures. That makes detached sheds unclear, and business-use containers don't fit.
The sales tax deduction. Under A.R.S. 42-5061(M), sales of solar energy devices are deducted from the state sales tax base. The definition of a solar energy device in A.R.S. 42-5001 includes systems designed primarily "to provide cooling" using solar energy. That law doesn't limit the property type, so if a fan qualifies, it may qualify whether it goes on a home, a shed or a container. The seller handles this one by registering with the Arizona Department of Revenue (Form 6015). City sales taxes may still apply.
Florida: fans are on the list
Florida's property tax law, Fla. Stat. 193.624, defines a "renewable energy source device" as equipment that "collects, transmits, stores, or uses solar energy," and the list includes "(f) Pumps and fans." The idea is that installing qualifying equipment shouldn't raise your property's assessed value. A solar-powered fan may qualify. Because this is a real property program, it may apply to homes and permanent sheds. Whether it applies to a shipping container depends on how your county assesses it.
Massachusetts: possible, for your main home
The Massachusetts regulation, 830 CMR 62.6.1, describes solar energy property as property that "transmits or uses solar energy directly to heat or cool a dwelling." Its examples mention "pumps or fans which circulate hot liquid or air." The state law sets the credit at 15% of the net cost, up to $1,000. A solar attic fan that cools your home may qualify. The credit is for your principal residence, so sheds are unclear and business use doesn't fit.
What about other states?
We also looked at the rest of the country. Many states have solar programs, but most are written for rooftop solar electric systems, solar water heaters, or large commercial projects, and we couldn't confirm any of them for fans. We'd rather tell you less than tell you something that isn't so. If your state isn't listed here, it doesn't mean the answer is no. It means we haven't confirmed a yes.
Important: check with a tax professional
This post is general information, not tax advice. Rules change, and whether a product qualifies can depend on your situation, how it's installed and how your state reads its own law. Before you count on any credit, exemption or deduction, check with a tax professional or your state revenue department. Keep your receipts and installation records either way.
As Daniel Rheaume of Solar Blaster puts it, "Our products move air, which is a natural cleanser. Clothesline fresh."
