Google Ads for Solar: Reaching People Who Have Already Decided

On Google you don't create demand: you collect it. And someone searching "solar system prices" has already done half the journey on their own.

Quick answer

Google Ads in solar is for intercepting people already searching, not for creating demand: it costs more per click than Meta but converts far better, with a cost per qualified lead between €15 and €40 in residential and between €50 and €150 in industrial B2B. The account should be split into separate campaigns for residential and industrial, because budget, sales cycle and language differ and mixing them makes the data unreadable. The keywords that pay are those with explicit buying intent — "solar system prices", "solar panel quote" — plus the geographic variant; informational and research queries should be excluded. The single biggest lever on cost per lead is the negative list: in this sector the wasted traffic comes from job searches, training courses and DIY kits.

In solar, Google and Meta do two different jobs, and confusing them is the mistake that sends most budget off course. Meta creates demand: it shows the system to homeowners who are not searching for anything. Google collects it: it speaks to people already comparing quotes. It costs more per click, and it is worth more, because the customer has already done half the convincing themselves.

How to structure the account

The first split is the one almost no installer makes, and it is the most important: residential and industrial B2B in separate campaigns. They have different budgets, sales cycles and language. Kept together, residential — cheaper and more frequent — absorbs the spend and hides the numbers for industrial, which is worth far more per contract.

Once that split is made, three campaigns for each branch:

  • Commercial intent. People searching for prices, quotes, costs. This is the heart of the account and where most of the budget goes.
  • Brand. On your company name. It looks like waste until a competitor bids on it and intercepts people who were looking for you specifically — at which point defending costs far less than recovering.
  • Incentives. Someone searching "solar tax deduction" or "2026 incentives" is motivated but often still researching: treat it as its own campaign, with a contained budget and a landing page that explains the numbers.

Which keywords pay

The rule is intent, not volume. The high-volume keywords in this sector are almost all informational, and they bring people studying the subject — not people choosing an installer.

Negative keywords: where most budget is recovered

This is the single biggest lever on cost per lead, and the one that gets maintained least. In solar, wasted traffic has four recurring sources:

  • Job searches. "Solar installer vacancies", "working in solar". High volume, zero commercial value.
  • Training and certifications. "Solar installation course", "installer qualification".
  • DIY. "Solar kit", "solar panel Amazon". Someone searching that way will never call an installer.
  • Research and curiosity. Everything starting with "how", "why", "what does it mean".

A maintained negative list produces results within the first few weeks, because it acts on spend rather than on conversion: it is the fastest intervention available on an existing account.

The ad and the landing page

Three things work in the ad: the keyword in the headline, which improves quality score and therefore lowers cost per click; the geographic marker, which reassures on proximity and avoids clicks from outside the area; and a concrete number instead of an adjective — estimated savings or payback time.

Traffic goes to a dedicated landing page, not the homepage. Someone arriving from an ad about price must find that answer and a short form, not the menu with the company history. The landing page has to state the area served, show real installations, and ask only for the data that qualifies — not ten fields.

What happens after the click

This is the part that decides whether Google Ads is sustainable, and it does not depend on Google. A €30 lead waiting two days for a call back is worth less than a €50 lead contacted within five minutes.

Automatic qualification before the site survey — property type, surface, annual consumption, existing system, urgency — is what stops the technician burning half-days on unsuitable roofs. We cover it in detail in solar lead generation, and the full cost-per-contract calculation is in cost per lead in solar.

In summary

Residential and industrial separated, keywords with buying intent, a maintained negative list that is the fastest intervention available, ads carrying a concrete number, and dedicated landing pages. The rest is played out after the click, on response speed and qualification.

Frequently asked questions about Google Ads for solar

The cost per qualified lead is between €15 and €40 in residential and between €50 and €150 in industrial B2B. Google costs more per click than Meta but converts far better, because it intercepts people who are already searching: the correct comparison is not on cost per click, it is on cost per site survey carried out and per contract signed.

The ones with explicit buying intent: 'solar system prices', 'solar panel quote', 'solar with battery storage cost', plus the geographic variant for the area you serve. Informational keywords such as 'how solar works' or 'is solar worth it' should be excluded: they bring research traffic and burn budget without generating site surveys.

By separating residential and industrial B2B into distinct campaigns, because they have different budgets, sales cycles and language, and mixing them makes the data unreadable. Then one campaign on commercial-intent keywords, one on your brand to defend against competitors bidding on it, and one on incentives, which in 2026 carries an extra lever.

They are the single biggest lever on cost per lead. In this sector the wasted traffic comes from job searches ('solar installer vacancies'), training ('solar installation course'), DIY ('solar kit Amazon') and purely informational queries. A well-maintained negative list cuts wasted spend noticeably within the first few weeks.

To a dedicated landing page, if the website is a company brochure. Someone arriving from an ad about system prices must find that answer and a short form, not a menu with the company history. The landing page should state the area served, show real installations, and ask only for the data needed to qualify.
