The Market Is Contracting, But Not Everywhere Equally
2026 has been a turning point for residential solar. Following the expiration of the Section 25D federal tax credit at the end of 2025, industry analysts including SEIA and Wood Mackenzie project residential solar installations will contract somewhere between 18% and 21% for the year. Major installers are feeling it directly — Sunrun expects a 25% drop in additions, with Enphase, SolarEdge, and SunPower projecting declines of 15% to 22%. For roofing contractors who added solar as a service line during the boom years, this is a real shift in demand, not a minor slowdown.
Regional Divergence Is the Real Story
National contraction numbers hide a more interesting pattern: some states are still growing sharply. Florida's residential solar additions are forecast to jump 62% year-over-year in 2026, and California is projected to grow 17% despite the broader national decline. For contractors operating in these regions, solar remains a strong opportunity even as the national headlines suggest otherwise — which is exactly why geographic targeting matters more than ever in this segment.
Third-Party Ownership Is Becoming the Dominant Model
With the customer-owned tax credit gone, the market is shifting hard toward third-party ownership — leases and power purchase agreements (PPAs) that still qualify for the commercial Section 48E credit through 2027. Analysts project TPO could capture up to 69% of residential installations in 2026, up from roughly 45% in 2025. Contractors who can position themselves within TPO financing structures, rather than only offering customer-owned system sales, are better positioned to keep volume steady through this transition.
Customer Acquisition Just Got More Expensive
Customer acquisition costs for residential solar have spiked roughly 40%, reaching an average of $0.84 per watt in 2026. This makes pre-qualified leads more valuable than ever in the solar segment — with acquisition costs rising industry-wide, contractors relying on cold outreach or unqualified web-form leads are absorbing a much larger cost per closed deal than those working with leads already confirmed for homeowner intent and budget fit.
Battery Storage Is Now Part of the Standard Pitch
Battery attachment rates have hit a record high, with roughly 45% of new residential solar systems now including battery storage. Homeowners are increasingly evaluating solar and battery backup together, particularly in states with unreliable grid infrastructure or high peak electricity rates. Contractors who can speak knowledgeably about battery pairing — even if they subcontract the installation — have an edge in these conversations.
Installer Consolidation Is Reshaping the Competitive Landscape
The bankruptcy of Freedom Forever, the second-largest national residential solar installer, in April 2026 signals a broader consolidation happening across the industry as financing partners pull back. Smaller, regionally focused contractors who maintain lean operations and diversified service lines — combining roofing and solar rather than relying on solar volume alone — are proving more resilient through this shakeout.
What This Means for Roofing Contractors Offering Solar
- Prioritize solar leads with confirmed roof-replacement need paired with solar interest, since combined jobs remain valuable even as pure solar volume softens
- Weight lead generation toward states and regions still showing growth, rather than assuming national contraction applies evenly everywhere
- Be prepared to speak to TPO and lease financing options, since customer-owned cash sales are a shrinking share of the market
- Treat solar as a longer recovery play — Wood Mackenzie projects the market returning to roughly 6% annual growth starting in 2027
Solar roofing hasn't disappeared as an opportunity — it's redistributed. The contractors who succeed in 2026 are targeting the right regions, adapting to TPO-driven financing, and working with leads that are already qualified for real intent rather than chasing a shrinking pool of unqualified inquiries.
