A real FHA program that allows solar to be financed directly into the mortgage at purchase or refinance. Not a separate solar loan. Not a lease. Not a power purchase agreement.
The FHA SWT program is an approved add-on to a standard FHA mortgage. Solar is financed inside the mortgage itself. The borrower owns the system outright. There is one mortgage, one payment, and no solar lien on the property.
Installation happens after closing. The lender escrows the solar funds. The borrower never takes on a second obligation.
Learn How It WorksThe FHA Solar and Wind Technologies program allows a solar energy system to be added directly to an FHA mortgage. It works at purchase. It works at refinance. The solar cost is part of the mortgage, not a separate financial product.
This is a borrower-owned system. Installation happens after the loan closes. The structure is one mortgage with solar included.
The FHA SWT program has specific requirements that borrowers, lenders, and realtors should understand.
When a homebuyer finances solar through FHA SWT at purchase, the process follows a defined sequence. The buyer's down payment is calculated on the home price alone. Solar is added on top.
The buyer identifies an FHA-eligible property. The property is evaluated for solar readiness based on roof condition, orientation, and shading.
The cost of the solar system is added to the FHA mortgage. The total loan amount includes the home price plus the solar installation cost, subject to the 20% cap.
The FHA loan closes as a single mortgage. Solar funds are placed in escrow. The buyer pays 3.5% down based on the home price only.
The solar installer begins work after the loan closes. The installation must be completed within 120 days.
Once installation is verified complete, the escrowed solar funds are released to the installer. The borrower owns the system free and clear.
Homeowners who already have an FHA mortgage can add solar when they refinance. The solar cost is rolled into the new loan. There is no separate solar loan and no lien.
This allows homeowners to add solar to their property at any point, not just at purchase. The refinance path eliminates the need for a second financial product entirely.
The FHA SWT program has been on the books for years. It was rarely used. The reasons are operational, not regulatory. The program works. The infrastructure around it did not exist.
SWT is not a product problem. It is an infrastructure problem. The FHA guidelines are clear. What was missing is the system to execute them.
Every piece of this infrastructure had to be built. The program itself was never the bottleneck. The missing layer was the operational system connecting every participant in the transaction.
FHA SWT changes the conversation with buyers. Solar is no longer a post-purchase decision with a separate loan. It is part of the home purchase itself.
This helps agents differentiate listings and offer buyers something tangible that competing properties cannot match.
This structure creates a path toward Clear-Title Solar. Because solar is inside the mortgage, there is no separate solar lien. This allows agents to position homes as solar-ready without introducing financing friction.
Homeowners who want solar but do not want a separate loan, a lease, or a lien now have a path. FHA SWT at refinance puts solar inside the mortgage.
The refinance path allows homeowners to add solar on their terms, at any point, without taking on additional financial products.
This is especially useful for homeowners who missed the opportunity to add solar at purchase. FHA SWT allows solar to be added later through refinance while keeping one mortgage structure.
Solar leases and solar liens create real problems for mortgage servicers. When a borrower has a third-party solar obligation, refinance friction increases. The servicing lender risks losing the borrower.
FHA SWT solves this.
The reason FHA SWT went unused was not a lack of demand. It was a lack of infrastructure. Making SWT work requires a system that connects every step of the process.
The borrower is pre-qualified for both the FHA mortgage and the solar add-on. Eligibility is confirmed before the property search begins.
The property is assessed for solar readiness. Roof condition, orientation, shading, and system capacity are evaluated before underwriting.
A qualified solar installer provides a binding bid before the loan enters underwriting. The cost is known. The scope is defined.
The appraisal is ordered on the home only. The solar system does not need to appraise. This is a critical distinction. The solar cost is added to the mortgage, but the appraiser values the property without the solar system. This removes the appraisal barrier that has blocked solar financing for years.
The FHA loan is structured with the solar cost included. Dual AUS submission is handled. The loan file meets FHA SWT guidelines.
Solar funds are escrowed at closing. The escrow is monitored through the installation period to ensure compliance.
The solar installation is completed and verified within the 120-day window. Escrow funds are released upon completion.
This is not a checklist. It is a coordinated system. Every participant in the transaction has a defined role and a defined timeline. That system is what turns the FHA SWT program from a policy on paper into a usable product.
