OBBBA Killed the 25D Solar Credit: What Multi-Modal Contractors Should Do Next

The One Big Beautiful Bill Act (OBBBA), passed in mid-2025, terminated the Section 25D residential clean energy tax credit for systems placed in service after December 31, 2025. Customers buying residential solar in 2026 cannot claim the 30% federal credit they could claim in 2025. The Section 48E commercial credit and the Section 25C heat pump credit survived. Residential solar took the hit.

For multi-modal electrification contractors who've built revenue mix around solar plus storage plus EV charging plus heat pumps, this is a structural shift. The customer-side economics on residential solar got materially worse overnight. The customer-side economics on heat pumps and commercial solar stayed intact. The playbook in 2026 has to adjust.

What actually changed

Before OBBBA:

• Section 25D: 30% federal tax credit on residential solar through 2032, with phasedown 2033-2034
• Section 48E: investment tax credit on commercial solar and storage, generally 30%+ with bonus adders
• Section 25C: $2,000 annual heat pump credit + $1,200 envelope credit, through 2032

After OBBBA:

• Section 25D: terminated for installs placed in service after December 31, 2025. Customers placing systems in service in 2026 cannot claim the credit.
• Section 48E: largely preserved with some changes to bonus credit qualification rules. Commercial solar and storage still get the ITC.
• Section 25C: preserved. Heat pump credit still available at $2,000 per year through 2032.

For a residential customer in 2026 buying a $25,000 rooftop solar system, the loss of the 30% credit is $7,500 of customer-side incentive disappearing. That's a real number that shows up immediately in customer payback math and close rates.

The Q1 2026 demand crater

Multi-modal contractors saw a predictable pull-forward effect in Q4 2025 — customers rushing to lock in systems before the December 31 deadline. The trade press tracked solar industry installation volume in Q4 2025 well above normal seasonality.

The Q1 2026 hangover is real. Residential solar leads in California and Texas were down 35-50% year-over-year in February 2026 per several public-company earnings calls and trade reporting. Some of that is the loss of the 25D incentive. Some is the NEM 3.0 economics in California finally fully working through the market.

The contractors most exposed to the demand crater are pure-play residential solar shops. Multi-modal contractors with heat pump, EV charging, panel upgrade, and battery storage revenue lines are less exposed because the other product lines didn't lose their federal incentives.

Where to redirect sales energy

Three places multi-modal contractors should shift sales attention in 2026:

1. Battery storage on the existing installed base. The 25D credit ended for solar but battery storage retrofits on existing PV systems may still qualify under certain interpretations. More importantly, NEM 3.0 in California and similar net-metering changes in other states have made battery economics on existing PV homes meaningfully better than they were in 2023. Customers with 2018-2022 rooftop PV systems are now strong candidates for battery retrofits. The job is a $12-20K install with high gross margin and existing customer relationship.

2. Heat pumps as the new lead product. The 25C credit is alive (see 25C heat pump tax credit 2026 guide). State programs like NYSERDA Clean Heat, Mass Save HPIN, and BayREN Home+ are intact and in some cases expanding. Customers who would have called you about solar in 2025 will be calling you about heat pumps in 2026 because state programs are louder and federal incentives still apply.

3. Small commercial solar. Section 48E preserved the ITC for commercial. Small commercial customers (strip retail, professional offices, light industrial) with 50-300 kW rooftop systems are an underserved segment in most markets. The competition is thinner than residential and the average ticket is meaningfully larger ($150K-$1M+ per project).

The revenue mix shift

A multi-modal contractor with a 2025 revenue mix of:

• Residential solar: 55%
• Battery storage: 15%
• HVAC / heat pumps: 20%
• EV charging and panel upgrades: 10%

Should be planning toward a 2026-2027 mix more like:

• Residential solar: 25-35%
• Battery storage: 20-25%
• HVAC / heat pumps: 30-40%
• EV charging and panel upgrades: 10-15%
• Small commercial solar: 5-15% (new)

The transition takes 12-18 months. The first move is repositioning the sales team to lead with heat pumps or batteries on inbound leads rather than reflexively leading with solar. That's a training problem more than a hiring problem.

The customer conversation that still works

Residential solar isn't dead in 2026 — the federal credit is gone but the payback math still works in high-cost utility territories and for customers who value energy independence. The conversation just has to be more honest about what changed.

The conversation that works in 2026:

1. Acknowledge the federal credit is gone for solar (don't pretend it isn't)
2. Lead with battery storage as the primary value driver — backup power, time-of-use arbitrage, NEM 3.0 economics
3. Position solar as the battery's fuel source rather than a standalone investment
4. Bundle with heat pump conversion if applicable to preserve a federal credit in the project (the 25C heat pump credit)
5. Stack state-level solar incentives where available (still meaningful in NY, MA, CA, NJ, CT)

The contractors who'll struggle in 2026 are the ones whose sales pitch is "solar is free with the federal credit." That pitch died December 31, 2025. The contractors who pivot to a battery-led, system-integration conversation are the ones holding gross margin.

Operations implications

The revenue mix shift has operations consequences:

• Solar install crew utilization will be lower in 2026 than 2025 — plan accordingly on crew sizing
• HVAC install crews will need to expand — and the labor market for experienced heat pump installers is tight
• Battery storage adds electrical scope that some solar installers haven't had to handle at scale — training investment required
• Small commercial requires PM capability that residential-only solar contractors typically don't have on the bench

The shops moving fastest in Q1 2026 are cross-training solar installers on heat pump work and bringing on a senior PM with small commercial experience. The shops sitting still are watching their solar crews' billable hours decline while their HVAC pipeline grows without the capacity to serve it.

OBBBA's 25D termination isn't the end of residential solar. It's the end of solar as the easy lead product. Contractors who reshape around battery storage, heat pumps, and small commercial will come through 2026-2027 with stronger revenue mix and better gross margins than the pure-play residential solar shops trying to wait it out.
