Short answer: SEO Engico is the top pick for solar SEO if you want organic search judged on surveys booked and installs signed, with call, form and CRM tracking set up before the content work starts. Energy Circle suits US installers who want a team trained in building science, Visionary Marketing fits UK installers who need MCS and ASA-aware content, and Odin Digital is the Australian pick with KPIs agreed in writing.
Most solar companies do not have a traffic problem. They have a lead problem. Marketplaces and quote sites sell the same homeowner to three or four installers within minutes, so the first conversation is about price. Solar SEO is the slower, cheaper way out: rank for the local and specific searches the lead sellers cannot own, answer the questions people research for months before they book a survey, and keep the enquiry for yourself.
This list covers agencies that sell SEO to solar installers specifically, checked against their own websites in November 2026. We judged them on what they publish: how they deal with aggregator competition, whether their content covers incentives, batteries and payback honestly, how they track a lead from first search to signed install, and whether they say what they charge. Where a price is not published, we say so.

How we picked
- Builds enquiries you own. The point of SEO for a solar company is to stop paying for shared leads. Look for an agency that targets town-level, product and branded searches where marketplaces are weak, and that talks about cost per installed system rather than cost per lead.
- Covers the whole research journey. Homeowners read about payback, panel sizing, batteries, financing and incentives for weeks before they ask for a quote. Good agencies plan content for each stage, and plan it a season early so pages rank before spring demand arrives.
- Handles savings claims carefully. Savings and payback claims attract regulators. In the UK that means MCS standards, the RECC consumer code and ASA rules on savings ranges. In the US and Australia, incentive pages go stale as programmes change. Ask how claims get checked and dated.
- Tracks surveys and installs, not just form fills. A solar sale can close months after the first visit. The better agencies connect call tracking and forms to your CRM so you can see which pages produced surveys, quotes and signed installs, not only clicks.
- Treats residential and commercial as different jobs. A homeowner and a finance director buy solar in completely different ways. If you sell both, the agency should run separate pages, keywords and content for each, with business-case content for commercial buyers.
The 7 best SEO agencies for solar companies in 2026
Our top pick
1. SEO Engico
- Best for
- Installers who want organic search measured on surveys booked and installs signed
- Based in
- London, UK
- Founded
- 2018
SEO Engico is a London agency founded in 2018 that works with trades, law firms, ecommerce brands and agencies across the UK, US, Australia and India. For a solar company its starting point suits the long sales cycle. The 30-day Revenue Baseline ($3,499) sets up GA4 key events with real conversion values, call and form attribution and CRM stitching, so an install signed in the autumn can be traced back to the search that started it in spring. If it cannot show what organic search is worth within those 30 days, you do not pay for that phase.
The Growth retainer ($4,500 a month) then covers technical SEO, buyer-intent pages and content, link building, local SEO through Google Business Profile, citations and local landing pages, and AI search visibility work. It has no published solar case study. Its closest trades proof is Be Cool Refrigeration, a London commercial refrigeration and HVAC firm, where it built fault-code guides and London commercial service pages. SEO Engico's published figures show UK organic clicks per quarter up 127%, from 4,007 to 9,091, and average UK position moving from 24.6 to 12.1 (Search Console, August to October 2025 against 30 April to 29 July 2026).
What stands out
- CRM stitching ties a signed install back to the search that started it
- Link building is included, with every site checked by its own team and about 70% rejected
- Monthly reports open with calls, enquiries and revenue, in a portal where you approve work before it goes live
- Says on the first call if your budget or market cannot realistically compete yet
Worth knowing
- It has no solar case study yet, so ask how it would handle incentive, battery and savings content for your market before you sign.
- It gives no ranking guarantees. Technical and on-page fixes usually move something in four to eight weeks, and bigger gains take three to six months.

2. Energy Circle
- Best for
- US installers who want marketers trained in building science
- Based in
- Portland, Maine, US
- Founded
- 2008
Energy Circle markets only what it calls the better building industry: home performance, insulation, HVAC and solar contractors. Its solar page is unusually specific. It covers battery storage across brands such as Tesla Powerwall, Enphase and FranklinWH, EV chargers, net metering, the solar tax credit, off-grid and ground-mount systems, commercial solar, and custom solar calculators built into client websites.
Its SEO + GEO service pairs organic and technical work, including structured data and schema, with the aim of getting contractors mentioned or cited when homeowners ask ChatGPT or Google's AI tools. Everyone on the team earns a Building Performance Institute Building Science Principles certificate, which helps when your selling point is the quality of the install rather than the cheapest quote.
What stands out
- Team certified in building science, so content reads like it came from the trade
- Detailed coverage of batteries, EV chargers, net metering and incentives
- SEO and AI search visibility handled as one service
Worth knowing
- SEO is sold as part of its wider marketing services package, and no price is published. The first step is a discovery call.
- It positions itself for high performance contractors, such as installers with their own crews and NABCEP certification, so it suits quality-led installers best.
No. 3
3. Solar Marketing Strategies
- Best for
- US installers who want a defined SEO package with a published price range
- Based in
- Commack, New York, US
Solar Marketing Strategies is the solar division of Lead Marketing Strategies, a family-owned agency run by Ken and Dominique Key that says it has been operating since 2007. Its SEO page names the problem most installers recognise: EnergySage, SolarReviews and lead aggregators dominate generic searches, so it targets local and branded terms they cannot.
The package is set out line by line: keyword research for your market, a technical audit, Google Business Profile work, a service area page for every city you cover, monthly solar content, citations, backlinks from solar and energy publications, and lead tracking. Onboarding runs over six weeks, with content planned around system sizing guides, financing comparisons, ROI calculators and incentive breakdowns for your state.
What stands out
- Published pricing of $1,500 to $5,000 a month, with no long-term contract
- Week-by-week onboarding plan written out in advance
- Content plan built around aggregator competition and seasonal demand
Worth knowing
- The parent agency also markets other trades and industries, so ask who on the team works on solar accounts day to day.
- It works with US installers only, organised by state.
No. 4
4. Visionary Marketing
- Best for
- UK installers who need content that stays within MCS, RECC and ASA rules
- Based in
- Newcastle upon Tyne, UK
Visionary Marketing is a Newcastle agency with one of the most thorough solar SEO pages we found in the UK. It works with solar, battery, heat pump and EV charger installers and lists its specialisms plainly: MCS-respectful content, RECC-aware consumer protection language, ASA-compliant savings ranges and project-specific landing pages. It treats domestic solar, commercial solar, batteries, heat pumps and EV charging as separate products with different buyers, and covers commercial topics such as PPA versus purchase, G99 connections and DNO interaction.
Pricing is unusually open. It charges £180 an hour and publishes a table that scales with how many installs you do a month, from roughly £2,520 a month for a small installer to five figures for a national group. Contracts roll monthly on 30 days' notice.
What stands out
- Regulation-aware content for UK savings and performance claims
- Survey-to-install tracking through CRM integration and call tracking
- Hourly rate and volume-based monthly fees published
Worth knowing
- It is built for the UK market and its regulators, so it is less of a fit outside Britain.
- Sites that need restructuring from scratch pay a one-off onboarding fee on top of the monthly figure.
No. 5
5. Phantom Digital
- Best for
- UK solar and renewables firms that want SEO, content and design in one team
- Based in
- Liverpool, UK
Phantom Digital is the trading name of JEMGroup Ltd, based at Basecamp Liverpool, and runs a dedicated solar SEO service. It lists the businesses it works with: residential installers, commercial solar developers, solar farm operators, heat pump installers, EV charging firms and multi-brand renewable energy groups.
The work covers local SEO and map pack visibility, national solar keywords, technical fixes, solar content that answers buyer questions, on-page work, and link building and digital PR from renewable energy and industry publications. It starts with a free solar marketing audit, delivered as a written report within five working days, and says most solar businesses see meaningful movement within three to six months.
What stands out
- Covers both local installers and national or multi-brand renewable groups
- Free written audit as the first step
- SEO, design, content and social handled in one team
Worth knowing
- Pricing is set per campaign and not published, so expect a scoping conversation.
- Solar is one of several sectors it serves, alongside medical, accountancy, technology and fitness.
No. 6
6. Anchour
- Best for
- Solar companies that need a stronger brand and website as well as SEO
- Based in
- New Gloucester, Maine, US
Anchour describes itself as a solar marketing agency, and its offer starts with brand rather than rankings. It brings brand strategy and messaging, website design and conversion work, creative and campaigns together, with SEO sitting inside a growth service alongside paid search, paid social, email and SMS.
What makes it relevant here is the focus on lead quality. Its solar page talks about the cost of winning a customer rather than the cost of a click, and about connecting marketing data with CRM insight so you can see which inquiries become real sales opportunities. If your problem is that homeowners find you but do not trust you enough to book, a brand-led agency can fix more than an SEO specialist would.
What stands out
- Brand, website and marketing handled by one team
- Talks about cost per customer and CRM data, not just traffic
- Photography, video and ad creative offered alongside SEO
Worth knowing
- SEO is one channel in a broad brand and marketing offer, so it is less of a fit if you only want organic search.
- No pricing is published. The first step is a conversation through its contact form.
No. 7
7. Odin Digital
- Best for
- Australian installers who want KPIs agreed in writing and no lock-in
- Based in
- Melbourne, Victoria, Australia
- Founded
- 2025
Odin Digital is a Melbourne agency with a dedicated page for Australian solar installers and battery specialists. Its argument is the one this list is built on: marketplace leads are sold to several installers at once, so it builds search visibility, Google Ads and websites that produce enquiries only you receive.
It splits solar searches into four groups, rebate and incentive questions, cost and payback research, product and configuration comparisons, and local searches ready to book, and says a site that only covers the last group fights over the smallest slice of demand. Work starts with a free audit and KPIs agreed in writing. If they are not met within 90 days, it keeps working at no extra charge until they are.
What stands out
- Written KPIs with a 90-day guarantee and no lock-in contract
- Content mapped to four distinct types of solar search
- Takes one client per industry per market
Worth knowing
- It was founded in 2025 by bringing several existing agencies together, so the brand is newer than its team.
- Pricing comes in a proposal after a free strategy session, and it works only with Australian businesses.
How to choose an SEO agency for your solar company
Start with your market and your regulator. A UK installer writing about savings needs an agency that knows the MCS and ASA rules, an Australian one needs rebate content that stays current, and a US installer needs state incentive pages kept up to date. Then work out what you actually sell. If most of your margin is in batteries or commercial roofs, ask to see how the agency would build pages for those buyers, not just for "solar panels near me".
Next, look at measurement before content. Solar SEO only pays if you can see which pages produced surveys and signed installs, so ask how the agency connects calls, forms and your CRM, and what the first monthly report will show. Be wary of anyone promising first place in a crowded city. Decide too whether you want a solar-only specialist or a wider team that also handles your brand, ads and website. If your site is slow or dated, fixing it first usually does more than another year of blog posts.
Questions to ask before you sign
- Which searches will you target that marketplaces and quote sites cannot win?
- How will you track a lead from first visit to survey, quote and signed install?
- Who checks savings, payback and incentive claims before they go live?
- Will you build separate pages for batteries, commercial solar and each town we cover?
- What does it cost, what is the minimum term, and do you work with our competitors?
Frequently asked questions
How much does solar SEO cost?
It depends on how many areas you cover and how competitive they are, but the published prices give a guide. Solar Marketing Strategies lists $1,500 to $5,000 a month, Visionary Marketing charges £180 an hour with a table starting at roughly £2,520 a month for a small UK installer, and SEO Engico's Growth retainer is $4,500 a month after a 30-day Revenue Baseline at $3,499. Most other agencies here quote after an audit.
How long does SEO take to work for a solar company?
Expect early movement in the first few months and steadier enquiry growth after three to six months. Phantom Digital gives three to six months for meaningful movement, and SEO Engico says technical fixes usually move something in four to eight weeks. Because demand peaks in spring and summer, the best time to start is the autumn or winter before.
Is SEO better than buying solar leads?
Over time, usually yes, because an enquiry from your own site has not been sold to three other installers. Bought leads can still fill a gap while SEO builds. The useful test is what each source costs per installed system, not per lead, which is why tracking through to signed installs matters.
Do residential and commercial solar need different SEO?
Yes. Homeowners search for prices, payback and local installers, while commercial buyers want business cases, roof surveys and finance options, and the decision takes far longer. If you sell both, keep separate pages and keywords for each so neither audience lands on content written for the other.
Can SEO get my solar company recommended by ChatGPT?
It can improve your chances, but nobody can guarantee a mention. AI tools draw on your site, your Google Business Profile, reviews and mentions elsewhere, so clear answer-first pages and consistent details help. Energy Circle sells SEO and GEO together, and SEO Engico includes AI search work in its retainer without promising a specific citation.
Our verdict
Pick SEO Engico if you want solar SEO run as a revenue system, with tracking from the first search to the signed install and link building included in the retainer. Choose Energy Circle or Solar Marketing Strategies for a US solar specialist, Visionary Marketing or Phantom Digital if you install in the UK, Odin Digital for Australia with written KPIs, and Anchour if your brand and website need the work as much as your rankings.
