Solar PPA vs Cash vs Loan: Cost Per Sale 2026

Hello Solar Squad,

What does it actually cost you to close one solar sale through paid advertising?

Most solar companies have a rough idea. But when you break it down by financing type cash, loan, or PPA the numbers tell a very different story. And in 2026, that gap is wider than it's ever been.

The residential ITC expired December 31st, 2025. Cash and loan pipelines are contracting. And according to Wood Mackenzie, overall residential solar customer acquisition costs are set to spike 40% in 2026 as companies compete for a shrinking buyer pool.

The Numbers

Let's talk industry benchmarks first, then break it down by offer type.

90% of our parter companies are running our full PPA appointment setting system. Some like Ultra Energy in Ariozna with a cost per sale of less than $650 per sale.

Why PPA Campaigns Convert Cheaper

• ✅ Zero Barrier Offer - $0 down, immediate bill reduction. No ROI calculation needed. Homeowners don't have to justify a $35,000 decision to their partner — they're saying yes to a lower electricity bill.

• ✅ ITC Expiry Makes PPA More Attractive Relative to Alternatives - The 30% federal credit that made cash/loan competitive is gone for residential buyers. PPA providers retain the credit at the business level, passing savings to the homeowner through lower rates.

• ✅ Electricity Bills Keep Rising - US residential electricity rates rose 7.4% in 2025 alone (Solar.com / EIA data). Every rate hike that hits homeowners is a PPA selling point. Your ad writes itself.

• ✅ Simpler Decision = Higher Close Rate - When the offer is explained correctly, PPA is a binary question: do you want to pay less for electricity? That simplicity lowers cost per sale and increases appointment quality.
