Solar installers: how to cut cost-per-lead 60% with AI lead qualification

Solar leads cost $80-200 each. Most die because reps can't call them back fast enough. Here's the AI qualification + routing system that turns cold leads into same-day appointments.

Solar installers: how to cut cost-per-lead 60% with AI lead qualification

Solar is one of the most lead-hungry industries in the world. You pay $80-200 per lead, and most of them die before a human ever talks to them. The economics only work if you respond in minutes — not hours.

Why solar is uniquely brutal for slow response

The solar buyer journey is unlike almost any other B2C category. A homeowner fills out a solar quote form on impulse — maybe triggered by a bill shock, an ad, or a neighbor getting panels. They then fill out 4-6 more forms within minutes because they're comparing options.

Whichever installer calls them first wins the conversation. The rest hit voicemail on an already-committed prospect. Response time isn't a nice-to-have in solar — it's the entire game.

What the AI qualifies

Solar has very specific disqualifiers. Rental properties, shaded roofs, low bills, bad credit — all of these waste rep time if they're not caught upfront. The AI voice agent runs through the same checklist a good SDR would, but in 3 minutes, 24/7.

  • Homeownership (renters disqualify automatically)
  • Monthly electric bill (under $100 usually disqualifies)
  • Roof type + age (flat roofs and 20+ year shingle roofs need special pricing)
  • Shading (heavy tree coverage reduces viability)
  • Credit profile (soft-pull where allowed; self-reported otherwise)
  • Timeline (active shoppers vs 'just curious' go to different sequences)
