Why the OBBB Killed Solar Credits for Homeowners but Kept Them for Banks
The One Big Beautiful Bill shifted residential solar from a consumer-led model to a corporate-led one. Here's why — and what it means for homeowners who can afford to buy a system outright.

If you can afford to buy a solar system with cash or a loan, the federal government no longer offers you a 30% tax credit. But if a bank buys that same system and leases it back to you? They get the full credit. Why would lawmakers do this?
You've hit on a major point of debate regarding the One Big Beautiful Bill (OBBB) signed in July 2025. The shift in policy essentially moves residential solar from a "consumer-led" model to a "corporate-led" model. Here is the breakdown of why this happened and how it changes the "who gets what" of solar power.
The Policy Rationale: "Economic Efficiency"
Lawmakers who supported the OBBB argued that direct homeowner tax credits (Section 25D) were a "middle-class subsidy" that drained the treasury without ensuring long-term grid stability. By shifting the incentive to Third-Party Owners (TPO) like solar companies and the banks that fund them, the government aims to:
**Professionalize Maintenance:** If a bank or corporation owns the system, they have a financial interest in keeping it running. A homeowner might let a broken inverter sit for months, but a corporation loses money every hour a system is down.
**Standardize the Industry:** Large financial institutions are easier to regulate and audit than millions of individual households.
**Control the Supply Chain:** The OBBB introduced strict Foreign Entity of Concern (FEOC) rules. It is much easier for the government to force a large company like Sunrun or Sunnova to prove their panels aren't from China than it is to track every DIY or local-installer purchase.
The Financial "Win" for Banks
This creates a massive opportunity for "tax equity" investors — typically large banks like JP Morgan or Wells Fargo.
**Monetizing the Credit:** Many homeowners don't actually have enough tax liability to use a $10,000+ credit in one year. Banks, however, have massive tax bills and can use those credits immediately at 100% value.
**The "Pass-Through" Reality:** In a lease or Power Purchase Agreement (PPA), the bank claims the 30% credit and uses it to "buy down" the cost of the system. This allows them to offer you a monthly rate that is lower than your utility bill. However, they keep the profit margin and the long-term ownership of the asset.
Impact on Homeowners with the Means to Buy
For homeowners who can afford to buy a system outright, the 2026 landscape is frustrating:
**Higher Upfront Cost:** Without the 30% credit, the payback period for a purchased system has jumped from roughly 6-8 years to 11-14 years in most states.
**Forced toward Leases:** Even if you have the cash, the math now often favors a lease because the leasing company can still get that 30% discount from the government, while you cannot.
**Loss of Asset Value:** When you own the panels, they add value to your home. When you lease them, the lease can sometimes complicate a home sale, as the new buyer must agree to take over the bank's contract.
The New Normal
The government has effectively decided that solar should be treated like a utility service you subscribe to, rather than an appliance you own. While this makes solar "affordable" through low monthly payments for more people, it strips the long-term wealth-building aspect of solar away from the individual and gives it to the financing entity.
For Maui homeowners, where electricity rates are among the highest in the nation, this shift is especially impactful. The economics of owning a solar system here still pencil out faster than the mainland — but losing a 30% credit on a $30,000+ system means leaving $9,000 or more on the table that a leasing company would still receive.
