When CAC Hits $0.84/W: What Changes for Reps

Your manager didn't invent the lead drought. Wood Mackenzie put a number on it: residential solar customer acquisition cost is set to jump 40% in 2026, to $0.84/W, after bottoming out at $0.60/W in 2025 (Wood Mackenzie). Installers are paying almost half again as much to land the same customer they landed last year, chasing a market that's shrinking at the same time, projected down roughly 18% in 2026 on top of prior declines.

That's not a rep problem. It's the whole industry's problem. But it lands on you first.

What actually shows up on your desk

Marketing spend is the line item that gets cut when CAC spikes and volume drops. That shows up as fewer company-supplied appointments, worse ones, or both. If your calendar's thinner than it was a year ago and nobody's told you why, this is why. It's not that you got worse at closing what you're handed.

Fewer company leads means self-generation stops being the thing top performers do for extra money and becomes the thing that keeps you employed. The rep who can knock a street cold and book their own sit is now worth more to a dealer than the one who only works what marketing feeds them, because marketing is feeding everyone less.

The bankruptcy list is a real objection now

More than 100 U.S. solar companies have shut down or gone bankrupt since 2023, including names homeowners recognize: SunPower, Lumio, Sunnova, Solar Mosaic, PosiGen, and Freedom Forever, the country's second-largest residential installer, which filed Chapter 11 in April 2026 and converted to Chapter 7 by August (GreenLancer). Homeowners read the news. "Is your company even going to be around to honor this warranty" isn't paranoia anymore, it's a fair question, and you should have a real answer before you knock the next door, not an improvised one on the porch.

That answer is about the company's balance sheet and backing, not your enthusiasm. If you don't actually know it, find out from your manager this week. Guessing on this one gets you caught.

What to do with this, starting this week

• Stop waiting on the lead feed. If your comp still rewards booked sits regardless of source, self-generated doors pay exactly the same as a company lead and don't disappear when the marketing budget does.
• Ask your manager directly what changed. Fewer leads, tighter territory, adjusted comp, say it plainly instead of letting reps guess and blame themselves.
• Get the ownership answer straight. Know who owns the paper on what you sell and whether that company is still standing in five years. A homeowner researching the bankruptcy list will ask, and a rep who dodges it loses the sit right there.
• Read the contraction as a filter, not a wall. A shrinking market with rising CAC is exactly the environment where reps who can still self-generate become scarce and valuable. Half the industry can't afford to knock anymore. That's your opening, not your excuse.

What this sounds like when a homeowner brings it up

• Homeowner: "Didn't some big solar company just go bankrupt? How do I know you'll still be around?"
• You: "A few have, you're right to ask. Here's who backs what we install, and here's what happens to your warranty if the installer changes, that's worth knowing before you sign with anyone, not just us."

Straight answer, no deflection, and it's the kind of question you should have already rehearsed before it lands on a real porch.

Drill the answer before you need it

Reciting your company's ownership structure to yourself is nothing like holding it steady when a homeowner names a bankruptcy they read about that morning. That's a live-conversation skill.
