A homeowner path to commercial solar benefits
Prosper helps homeowners understand a commercial tax structure designed to capture credits, depreciation, and eligible interest deductions—or convert qualifying benefits into a cash payment.
The structure, in plain English
Confirm ownership, placed-in-service timing, equipment, system value, and the documents needed for tax review.
Use the residential application of a commercial tax-equity framework built on established solar precedent.
Keep eligible benefits, transfer qualifying benefits for an illustrative 25% cash amount, or evaluate a partial transfer.
Paramount prepares the applicable tax forms, with a Letter to Accountant and audit-support process available for review.
The deadlines are real
The old residential credit under Section 25D ended for expenditures after December 31, 2025. The commercial framework follows a different set of timing rules.
For qualifying solar construction begun by this date, the program describes the commercial credit as following the longer statutory phaseout schedule after 2032.
The program states that qualifying solar systems must be placed in service by December 31, 2027.
The program states that batteries are exempt from the 2027 solar deadline. Eligibility still depends on the project facts and tax review.
Existing systems may be reviewed for amended returns within the applicable IRS three-year amendment window.
Real filings. Redacted for privacy.
These are the core forms homeowners and their tax professionals should understand before moving forward.
Investment Credit. Used to calculate qualifying business energy credits, including the commercial clean-electricity investment credit.
Depreciation and Amortization. Reports depreciation deductions tied to the commercialized solar asset.
Profit or Loss From Business. Reports the activity connected to the homeowner's solar business structure.
Healthy skepticism is welcome
Large tax incentives are policy choices written into law, not informal rebates. The final benefit still depends on eligibility, valuation, documentation, and the signed program agreement.
Most CPAs focus on traditional W-2 homeowner returns. The residential application is newer, while commercial tax equity has decades of precedent. A Letter to Accountant is intended to help your tax professional review the framework.
The program reports more than 2,000 customers and no audits so far, while also acknowledging that the structure has not yet been tested in one. Every homeowner should review the written audit-support terms.
The structure is presented as a commercial tax framework built with Nelson Mullins. Prosper encourages every homeowner to read the legal foundation and send it to an independent tax professional.
Your numbers, not a sales pitch
