The Solar Installer's Secret Weapon: Building Permit Alerts
The solar industry spends an obscene amount of money acquiring customers. The average cost per lead ranges from $50 to $200, and the average cost to acquire a customer is north of $3,000. Meanwhile, there's a free, public data source that identifies the most qualified solar prospects — and almost nobody is using it.
Why Roofing Permits Are the Best Solar Leads
A homeowner who just got a new roof has eliminated the #1 objection to solar: "my roof is too old." Their roof is brand new, structurally sound, and warranty-intact. The close rate on new-roof homeowners is dramatically higher than cold leads from any other source.
Beyond Roofing: Other Permit Types
New construction permits: Homeowners making all their major systems decisions right now. Solar is easiest during construction.
Addition permits: Someone adding square footage isn't planning to sell next year — and their electricity bill is about to increase.
Electrical panel upgrades: Often a prerequisite for solar. If someone is already upgrading, the marginal cost of adding solar drops significantly.
Pool permits: Pool equipment can add $100-200/month to an electric bill — making solar an easy sell.
The Economics
Phoenix averages 400-600 roofing permits per month. Add new construction, additions, and electrical upgrades: 800-1,000 relevant permits per month.
Permit monitoring costs $150/month = roughly $0.15-0.19 per lead. Compare to:
- Google Ads solar leads: $75-150 per lead
- Lead aggregators: $50-100 per lead
- Door-to-door: $30-60 per lead
Even if only 10% of permit leads are reachable and interested, your effective cost per qualified lead is $1.50-1.90. That's 30-50x cheaper than Google Ads.
What Your Competitors Are Doing
Large national solar companies already monitor permit filings with automated systems. But they have massive overhead and slow response times. A local installer who calls homeowners the same week their roof is completed will beat a national company every time.
