If you're a solar installer trying to decide between Google Ads or SEO, the honest answer is: start with Google Ads, then build SEO underneath it. Solar is a high-ticket, slow-consideration purchase, and you can't afford to wait six months for organic rankings while your crews sit idle. Ads buy you leads this week. SEO makes those leads cheaper next year. You need both, but not at the same time.
Why solar is a special case
A residential solar job runs $15,000 to $30,000 before incentives. A commercial job is far more. That means one closed deal pays for months of ad spend. It also means the buyer takes weeks or months to decide, gets three or four quotes, and researches heavily. Your marketing has to catch them at the exact moment they type "solar installer near me" or "solar panel cost [city]."
That timing is why paid search wins the first round. When someone searches with buying intent, you want to be at the top of the page that day, not hoping you rank by spring.
What Google Ads gets you first
Ads put you in front of people already shopping. For solar, expect clicks to cost real money, often $8 to $25 depending on your market, because the ticket size is high and competition is fierce. But the math still works when a single install is worth tens of thousands.
- Leads within days of turning campaigns on
- Control over which zip codes and services you show up for
- Fast data on which keywords actually produce booked consultations
The catch: solar attracts tire-kickers and lease-versus-buy confusion. You'll need strong lead qualification and a clear offer, or you'll pay for calls that never close.
Where SEO earns its keep
SEO is slow to start and hard to kill once it works. For solar, the organic wins come from content that answers the questions buyers actually ask: how much does solar cost in my state, is my roof a good fit, what happens to the tax credit, how long until it pays off.
These pages don't convert on the first visit. They build trust over the long research cycle, and they capture the "cost" and "worth it" searches that ads are expensive to compete for. Six to twelve months in, a chunk of your leads start arriving free.
A realistic sequence
- Months 1–3: Launch Google Ads on high-intent terms. Get a lead flow going and fund your crews.
- Months 2–6: Build out location and cost pages, get Google Business Profile reviews rolling, publish honest guides on incentives and payback.
- Months 6–12: Organic leads start supplementing ads. Now you can pull back paid spend on the terms you rank for and reinvest in weaker markets.
What most installers get wrong
They pick one and treat the other as a waste. An installer who only runs ads is renting every lead forever, and the day the budget stops, so do the calls. An installer who only does SEO is invisible during the two quarters it takes to rank, which in a seasonal, incentive-driven business can mean missing a whole buying window.
The other common mistake is sending both to a weak website. Solar buyers vet you hard. If your site has no real project photos, no reviews, no clear financing explanation, and no fast way to book a consult, it doesn't matter how they found you.
How to decide your split
If you need installs booked this quarter, lead with ads and give them the bigger budget. If you're established with steady referral flow and want to lower cost-per-lead over the next year, weight more toward SEO while keeping a smaller always-on ad campaign for the high-intent searches.
The right answer for most installers is roughly 70% ads, 30% SEO to start, then shifting toward 50/50 as your organic pages mature. The goal is to stop paying full price for leads you could earn for free once your site does the ranking for you.
Solar has enough margin per job that you don't have to choose. Fund the pipeline with ads now, build the organic engine underneath it, and in a year you'll have both a steady lead flow and a lower cost per install than the competitor still renting every click.
