Facebook ads for solar installers in San Diego changed completely after NEM 3.0. The old playbook, a stock photo of a roof, a "see if you qualify" form, and a $200 lead that a call center chased for a week, produced garbage leads in 2022 and produces worse ones now. The homeowners who are still buying solar in this county are buying it with a battery, they are more skeptical, and they respond to a very different kind of ad. Here is what is working for installers we work with across the county.
What NEM 3.0 did to the customer
Under the old net metering rules, solar alone paid for itself quickly and the pitch was simple. Now that SDG&E pays a fraction of retail for exported power, a solar-only system is a much weaker deal and the math only works with storage that shifts usage into the evening peak. The customer who searches and scrolls now already knows this, or half-knows it, and is suspicious of anyone who does not lead with batteries. Your ads should say "solar plus battery" in the first line and explain the evening-peak logic in plain language. SDG&E rates being among the highest in the country is your friend; use the actual rate story, not vague "save money" claims.
Neighborhoods that still convert
Solar interest correlates with home ownership, roof size, high bills, and money to finance a $30,000-plus system. In San Diego that points at:
- I-15 corridor: Rancho Bernardo, Poway, 4S Ranch, Scripps Ranch, Rancho Peñasquitos. Big roofs, pools, hot summers, high bills, and a lot of homeowners who already have panels and now want a battery added.
- East County: El Cajon, Santee, Lakeside, Alpine, Ramona. Hotter, higher AC bills, more outage-conscious after fire-related shutoffs. Battery backup messaging lands hard here.
- North County inland: Escondido, San Marcos, Vista, Fallbrook. Similar profile plus a real interest in resilience.
- South Bay: Eastlake, Otay Ranch, Bonita. Newer homes, big families, big bills, and a Spanish-language ad set usually earns its budget.
- Coastal and La Jolla: smaller roofs, milder bills, more interest in EV charging and aesthetics than payback. Different creative.
Exclude renters explicitly through homeowner and interest signals, and exclude the dense apartment areas (Downtown, Hillcrest, most of Pacific Beach) where your ad will reach a lot of people who cannot buy.
Creative that survives skepticism
The ads that hold up now are honest and local. A 45-second video of your installer standing next to a battery in a Poway garage, explaining what it does during the 4 to 9 p.m. peak and during an outage. A screenshot of a real SDG&E bill before and after (with permission, no personal info). A plain-text ad that says what a typical system in Santee costs after incentives and what the monthly payment looks like. Testimonials with the neighborhood named. What does not work anymore: "the government will pay for your solar," fake countdown timers, "program" language, anything that looks like the lead-gen ads that burned the whole county.
Lead cost and budget reality
Solar is one of the most expensive Meta categories anywhere and San Diego is no exception. Expect $60 to $200 per lead from a well-built lead-form campaign, and $30 to $100 for a landing page lead from retargeting. Qualified appointment cost usually lands in the $200 to $500 range once you account for the ones who do not answer. A serious installer should plan on $3,000 to $8,000 a month in Meta spend to keep a sales team fed; below about $1,500 the algorithm does not have enough signal to optimize. Use the instant form for volume but add qualifying questions (own your home, monthly bill range, roof age) and expect volume to drop and quality to rise.
Compliance is not optional
Solar is a special ad category adjacent business on Meta and the platform has been cracking down on misleading energy claims. Do not say "free," do not imply a government program, do not fabricate savings figures. California's consumer protection rules for solar sales are also stricter than most states. A manager who has run solar in this state should know the disclosure requirements; if they look confused when you ask, they have not.
The existing-customer opportunity
There are hundreds of thousands of solar-only systems in San Diego County on legacy net metering. Those owners are hearing about batteries and about their NEM 2.0 clock. A custom audience built from your past customers plus a lookalike, with a "we installed your panels, here is what adding a battery looks like" ad, is usually the cheapest lead source in your account. Do not neglect it.
Management and what to pay
At $3,000 to $8,000 in monthly spend, a fair management fee is $1,000 to $2,500 a month, and it should include creative production, weekly lead quality review with your sales team, custom and lookalike audience work, and compliance oversight. Beware pay-per-lead vendors reselling the same leads to four installers. Here is how Arbor runs your ads for local companies, and run your site through our free SEO & AI score because a retargeting campaign is only as good as the landing page behind it. The inland targeting notes in Facebook Ads Management in Fallbrook for Local Businesses apply well to solar in the rural parts of North County.
Facebook ads for solar installers in San Diego still work, but only for installers willing to lead with batteries, name real neighborhoods, and tell the truth about the math. The lead-gen era is over here; the honest era is cheaper anyway.
