The Complete Guide to SEO for Solar Companies

Everything a solar firm needs to understand about being found, built from a 10,003 keyword pull. Written around a buyer who researches for weeks, arrives braced for a pitch plus checks your credentials before they read anything else.

2,247,850 searches mapped

Solar is not won at the moment somebody searches for an installer. Near-me terms carry 33,310 monthly searches. Cost, funding, installation questions plus roof suitability carry well over four hundred thousand between them. By the time somebody looks for a company near them the shortlist already exists, formed weeks earlier around whoever answered their questions without trying to close them. This guide is about being that firm.

Where the numbers come from, plus one warning about them. A 10,003 term UK keyword pull carrying 4,563,280 monthly searches. That headline figure is worthless. The word solar catches garden lights, water features, the solar system, eclipses, solar plexus, a television programme plus a streaming site people misspell. We stripped 4,126 terms carrying 2,315,430 searches, which is 51% of the file, the worst contamination in any trade we work in. What remains is 5,877 terms carrying 2,247,850, plus that is what every figure here refers to. Two things this guide will not do: present a payback or savings figure as a fact rather than an illustration, nor suggest anything built on free solar framing. Your sector's reputation was made by firms doing both. Individual subjects each have their own guide, all linked from the guides hub.

Part one
What The Buyer Is Doing
SECTION 01

What Solar Customers Look For Before Enquiring

Start here, because everything else in this guide follows from it. Your visitor is not browsing. They are auditing you, plus they have a list.

Are you legitimate. First, always, plus checked before anything else on the site is read properly. Certification, consumer code membership, insurance-backed warranty, company age, registration numbers. Your visitor has read about firms that took deposits and vanished, so this is not a trust exercise, it is a filter.

What does it cost. 162,900 monthly searches at a difficulty of 32 ask this, plus almost nobody in your sector answers. The industry norm is to withhold the number until somebody is sitting in a living room. Your buyer knows that norm exists, which is precisely why silence reads as evasion rather than as professionalism.

Will it work on my roof. Orientation, pitch, shading, tile type, age of the roof, whether it needs work first. 42,970 monthly searches at a difficulty of 20 are people trying to answer this before they involve anybody. Almost no installer site addresses it properly.

What will I actually save. Not what the best case is. What a house like theirs, with their usage, on their tariff, might reasonably expect. Section eleven covers why the realistic version of this converts better than the optimistic one.

What happens if something goes wrong. Who fixes it, for how long, what the warranty covers and who honours it if you stop trading. This is the question your buyer is most anxious about and least likely to ask.

Are you going to sell at me. Underneath all of the above sits one question your visitor will never type into a search box. They are deciding whether contacting you triggers a sales process they cannot easily stop.

The Takeaway

Legitimacy, cost, roof suitability, realistic savings, what happens if it goes wrong plus whether enquiring means being sold to. Answer six questions and you have done more than most of your competitors combined.

SECTION 02

Content For Every Stage Of The Buying Decision

Solar has the longest research phase of any trade we work in. Months, frequently, across dozens of sites and several devices. The content has to match where somebody is rather than where you would like them to be.

Stage one, wondering. Is this worth doing at all. What does it cost roughly. Would my roof even work. Is there help with the money. This is where the volume is: cost at 162,900, funding at 97,450, roof questions at 42,970. Nobody at this stage wants a quote form. They want an answer.

Stage two, comparing. Panel types, battery sizing, in-roof against on-roof, what an inverter does, what a good warranty looks like. Battery storage alone carries 136,520 searches at a difficulty of 24. Somebody here is building a mental specification, plus whoever explains it clearly becomes the benchmark they judge other quotes against.

Stage three, shortlisting. Now they are looking at firms. Certification, reviews, how long you have traded, what your installs look like, whether you work in their area. The shortlist forms here, usually to three names.

Stage four, quoting. Only now do they search for an installer near them. 33,310 monthly searches, 96% of which return a map. Your listing has to be right by this point, though the decision about who to contact was largely made in the three stages above.

Why this matters more than it sounds. Most solar websites are built entirely for stage four. Home page, services, contact, get a free quote. That site is competing for the smallest of the four groups, at the point where three competitors are already on the list.

Part two
The Search Itself
SECTION 03

The Keywords Worth Targeting, Plus The Trap

The trap first, because in your trade it is bigger than in any other we work in.

Half of your sector's apparent search volume does not exist. A raw pull for solar returns 4,563,280 monthly searches. 1,942 terms carrying 990,720 are garden lights, water features, fountains, solar chargers plus camping kit. Another 1,225 terms carrying 705,570 are astronomy: the solar system, eclipses, solar flares. Then solar plexus. Then a television programme. Then a streaming site. Strip it all and 51% of the file is gone.

The test to put to any agency pitching you. Ask what the addressable market is. If the number starts with a four, they have counted every garden light in the country plus every eclipse search from the last two years. That single question will tell you more than an hour of their presentation.

What is actually worth targeting. Panel installation at 171,900 and a difficulty of 33. Cost at 162,900 and 32. Battery storage at 136,520 and 24, which is the best volume-to-difficulty combination in the file. Funding and grants at 97,450 and 34. Commercial at 50,430 and 25.

Then two nobody is competing for. Maintenance, cleaning and repair carries 45,280 searches at a difficulty of 16, with individual terms in the low teens. That is recurring revenue from an install base that already exists, which is rare in a trade otherwise built on one-off capital sales. Roof type and suitability carries 42,970 at a difficulty of 20, which is pure research-stage demand and exactly the phase section two says decides everything.

And one we would not build. EV charger installation carries 6,980 searches at a difficulty of 20. Genuine demand, though if it is already covered elsewhere on your site or by a sister business, a second page competing with the first helps nobody.

SECTION 04

How Google Reads A Solar Website

Two things decide how much of your site gets understood: whether it can be crawled properly, plus whether the content answers something specific.

The crawl basics that break most solar sites. Pages with no unique title. Headings used for size rather than structure. Images uploaded straight from a phone at full resolution, which is common in a trade that photographs every install. Redirect chains left behind from a rebrand. None of it is glamorous, plus a quarterly audit catches all of it before it compounds.

The bigger problem is thinness. A services page listing panels, batteries and EV chargers as three paragraphs is not competing for any of them. Google reads it as one page about solar generally, which is a subject with several million searches attached and no chance for a regional installer.

What Google is looking for in your trade specifically. Because 48% of the demand we measured returns an AI answer, one of the highest shares in our programme, the material that gets drawn on is factual, specific plus clearly attributed. A page that says a battery might save you money is not usable. A page that explains how battery sizing relates to household usage, with the variables named, is.

The signals that matter more here than elsewhere. Certification and company details, consistent everywhere. Real photographs of your own installs rather than manufacturer stock images, which appear on hundreds of competitor sites. Named authors where you have somebody qualified to name. Dates on anything referencing schemes, tariffs or grants, since that material ages fast and stale pages read as abandoned.

SECTION 05

Schema Markup For Solar Companies

Schema is structured data that tells search engines what things on your page are rather than leaving them to infer it. In a trade where 48% of demand returns an AI answer, that matters more than it does for most local businesses.

What we mark up on a solar site. Your business as a local business, with address, phone, opening hours plus the areas you serve. Each service you install as a distinct service rather than a paragraph. Your reviews. Your FAQs, which is the highest-return markup in your trade for the reason in section twelve. Any article or guide you publish, with an author.

Where solar firms get it wrong. Marking up services you do not offer, because a template included them. Marking up review scores you cannot evidence. Leaving old markup in place after a rebrand so two different company names are declared. All three do more harm than no markup at all.

The one place to be careful. Do not mark up savings figures, payback periods or performance claims as structured facts. Structured data is read as an assertion. An illustration presented as an assertion is a problem you do not want, plus it is the exact mistake that has caused trouble in your sector before.

None of this is visible to a visitor. It costs nothing beyond the time to do it accurately, plus it is one of the few things in SEO that is entirely within your control.

SECTION 06

Internal Linking For Solar Websites

Internal linking decides how much of your site's authority reaches the pages meant to be earning. It is free, entirely within your control plus neglected on nearly every solar site we audit.

The structure that works in this trade. Service pages sit at the top level, one per thing you install. A guides hub sits alongside them holding the research-stage content. Every guide links to the relevant service page. Every service page links back to your certification page, your pricing page plus the guides that answer its obvious questions.

Link the way the buyer moves. A roof suitability article links to panel installation. A panel installation page links to battery storage, since that is the next question. A battery page links to export tariffs. Somebody reading about grants links to certification, because eligibility usually depends on it. Each link should be the thing that person would sensibly want next, rather than a keyword dropped into a paragraph.

Point authority at the pages that convert. Your certification page and your pricing page are checked by nearly every serious enquiry, plus neither attracts much search volume on its own. Linking to them from everywhere is how they stay strong.

One warning for a re-siloed site. If pages have moved, every internal link has to move with them. A site full of links to old addresses that redirect works, though it leaks a little at every hop and it is a five minute fix at build time against an hour later.

Part three
The Website
SECTION 07

The Landing Pages A Solar Company Needs

More pages than most installers have, though far fewer than an agency selling volume will suggest. This is the working list.

  • A page per service you install, meaning panel installation, battery storage plus commercial work separately rather than as a list
  • A certification and accreditation page covering your registrations, consumer code membership, insurance-backed warranty plus who honours it
  • A pricing page with real ranges and what moves them, covered in section eleven
  • A roof suitability page answering orientation, shading, tile type plus what disqualifies a roof, which is 42,970 searches almost nobody serves
  • A funding page, only if you genuinely deliver funded work, written factually and never as free solar
  • A maintenance and cleaning page if you service systems, which is 45,280 searches at a difficulty of 16
  • Your installs, photographed properly, with the system size, the roof type plus what the customer wanted
  • A what happens next page setting out survey, design, install day, handover plus aftercare
  • Area pages for the towns you genuinely cover, describing real work done there rather than a template with a place name swapped in
  • An FAQ, covered in section twelve

What the list does not include is a page for every village within fifty miles, nor a blog explaining how solar panels work, which is a subject already answered by every energy supplier and comparison site in the country.

SECTION 08

Writing Solar Content That Ranks And Converts

The content problem in your trade is not volume. It is that almost everything published is either a sales page pretending to be an article, else a generic explainer that a hundred larger sites already own.

Write for the specific, not the general. How solar panels work is not a subject you can win. Whether a north-east facing roof is worth doing, what happens to output with a chimney casting afternoon shade, how battery sizing changes if somebody works from home, what a slate roof adds to an install: those are specific, answerable plus barely contested.

Name the variables rather than averaging them. The temptation is to write it costs around this and saves around that. Averages are useless to somebody with a specific house, plus they are how the sector got its reputation. Naming what changes the answer, meaning orientation, shading, usage pattern, tariff, system size and roof access, is more useful and more credible than any single figure.

Say what you would not recommend. Which roofs you would turn down. When a battery does not pay for itself. When somebody should wait. This feels like leaving money on the table and it does the opposite, because a buyer who has been told no about something believes the yes.

Date anything that ages. Tariffs, schemes, funding and export rates all move. An undated page about a scheme that has changed reads as a firm that stopped paying attention.

Use your own installs. Photographs of your work with the system size, the roof type plus what the customer was trying to achieve beat manufacturer stock images that appear on four hundred other sites.

The Takeaway

Specific beats general, named variables beat averages, telling somebody what you would not recommend earns the trust that sells the rest plus your own installs beat stock photography every time.

Part four
Turning Reading Into Enquiry
SECTION 09

Call To Action Strategies That Work In Solar

Most solar sites have one call to action, repeated on every page, aimed at the smallest group of visitors they have. Somebody three months from buying is asked to book a survey.

Match the ask to the stage. A visitor reading about roof suitability is not ready to meet anybody. A visitor comparing battery sizes is closer. A visitor on your certification page is close. Three different asks, not one.

What works at the research stage. Something useful that costs nothing and commits to nothing. An indicative price range for their property type. A roof suitability check by email. A written guide. The point is to be the firm they got something from rather than the firm they gave a phone number to.

What works at the comparison stage. A specification conversation rather than a sale. Somebody at this point wants to know whether their thinking is right, plus a firm willing to have that conversation without pushing becomes the one they trust to quote.

What works at the quoting stage. Be specific about what happens. A survey that takes this long, carried out by this person, producing this document, with no obligation and no visit required first if they would rather not. Vagueness at this point costs you the enquiry.

What does not work anywhere. Countdown offers. Limited availability claims. Prices that expire. Finance framed as the reason to proceed. Beyond the compliance problem, your buyer has met all of it before plus every one of those devices confirms the suspicion they arrived with.

SECTION 10

Building A Lead Funnel

A funnel in this trade is not a sequence of emails. It is a route through your site that matches a decision taking months.

The top is research content. Cost, roof suitability, funding, battery basics. This is where the volume is plus where the shortlist forms. Measured properly, most of your eventual customers first arrived here.

The middle is comparison material. Your service pages, your installs, your certification, your warranty position. Somebody moves here when they have decided to do it and are working out who with.

The bottom is the enquiry route, which should be short, specific about what happens next plus available without a phone call for anybody who would rather not have one.

The part most firms miss. There is a long gap between the top and the bottom, plus a returning visitor should not land back on your homepage. Somebody who read your roof suitability guide in March and comes back in June should find the next thing rather than the same thing.

Measure it properly. Attribution across a months-long decision, on several devices, is never clean. Ask at enquiry how they first came across you, record it plus treat the pattern rather than the precision as the answer. A firm judging this work on last-click will conclude the research content does nothing, when it is what put them on the list.

SECTION 11

Why Free Quotes Stopped Converting

Get A Free Quote was the entire industry's call to action for a decade. It works far less well than it used to, plus the reason is worth understanding properly rather than replacing the button and hoping.

Free stopped meaning free. Your buyer has learned, from friends or from coverage, that a free solar quote frequently means a salesperson in their living room for two hours, a price that drops when they hesitate plus a follow-up they cannot easily stop. The word free no longer signals no cost. It signals no escape.

It also asks for everything and offers nothing. Name, address, phone, email, in exchange for a process they cannot see the shape of. At the research stage, which is where most of your traffic is, that trade is obviously bad and they close the tab.

What to replace it with. Give something before asking for something. An indicative price range for their property type, published rather than gated. A roof suitability check they can do themselves in two minutes. A written estimate by email with no visit. Each of those is useful on its own, plus each one identifies somebody genuinely interested rather than somebody who filled a form to see a number.

Then be explicit about the process. How long a survey takes. Who attends. Whether they get a written quote or a presentation. Whether the price is the price or an opening position. A firm that publishes this converts against firms that will not, because the anxiety it removes is the exact anxiety stopping the enquiry.

And be careful with savings figures wherever they appear. Illustrations with the assumptions named, never a payback period presented as a fact. That is not only a compliance position, it is a conversion one. Your buyer has already seen the optimistic version somewhere else and discounted it.

The Takeaway

Free quote now reads as a sales appointment rather than a favour. Give something first, publish an indicative range, be explicit about what a survey actually involves plus keep every savings figure framed as an illustration.

SECTION 12

Using FAQs To Move People Towards Enquiry

FAQs do more for a solar firm than for almost any local business, because your buyer has a long list of questions and no wish to ask a salesperson any of them yet.

The questions people need answered before they will make contact. How much does a typical system cost. Will my roof work. How long does an install take. Do I need scaffolding. What happens to my roof warranty. How long do panels last. What happens if a panel fails in year eight. Who honours the warranty if you stop trading. Do I need planning permission. What is your certification and where can I check it. Can I add a battery later. What do I actually get paid for exporting. Will you tell me if it is not worth doing.

Every one unanswered is a reason to keep researching somebody else.

Why this is the highest-return content in your trade. 48% of the demand we measured returns an AI answer, one of the highest shares in our programme. A clear question followed by a direct factual answer is exactly the format those systems draw on, so a properly built FAQ earns twice: it reassures the reader plus it becomes the source.

Add FAQ schema so search engines can read the structure, then put the service-specific questions on those pages rather than only on a central FAQ, because that is where they are being asked.

One question worth answering that almost nobody does. What happens if I contact you. Say plainly whether it triggers a call, how many, plus how somebody stops it. In a sector where the fear of being pursued is the main brake on enquiry, answering that removes more friction than any other line on your site.

Frequently Asked

Why has our free quote button stopped working?
Because free stopped meaning free. Your buyer has learned that a free solar quote frequently means a salesperson in their living room for two hours, a price that drops when they hesitate plus a follow-up they cannot easily stop. The word no longer signals no cost, it signals no escape. Replace it with something that gives before it asks: an indicative price range published rather than gated, a roof suitability check they can do themselves, plus a written estimate by email with no visit. Section eleven covers it.
How do we know an agency has actually done the keyword work?
Ask what the addressable market is. A raw pull for solar returns 4,563,280 monthly searches, plus 51% of it is garden lights, water features, the solar system, eclipses, solar plexus, a television programme and a streaming site. If the number they quote starts with a four, they have counted every garden light in the country. The real figure after filtering is 2,247,850, plus even that needs narrowing to your own patch. Section three covers it.
Should we publish prices?
Yes, plus in this trade it does more work than in almost any other. 162,900 monthly searches ask what solar costs and hardly anybody in your sector answers, because the industry norm is to withhold the number until a salesperson is in the room. Your buyer knows that norm exists, which is exactly why silence reads as evasion. Publishing a real range with what moves it puts you on a shortlist that forms weeks before anybody asks for a quote. Sections one and eleven cover it.
What content should we write that we are not writing now?
Specific rather than general. How solar panels work is a subject you cannot win, since every energy supplier and comparison site already owns it. What you can own is whether a north-east facing roof is worth doing, what a chimney casting afternoon shade does to output, how battery sizing changes for somebody working from home plus what a slate roof adds to an install. Name the variables rather than averaging them, plus say plainly what you would not recommend. Section eight covers it.
Which two opportunities are we most likely missing?
Maintenance and cleaning at 45,280 monthly searches with a difficulty of 16, which is recurring revenue from an install base that already exists and is rare in a trade otherwise built on one-off capital sales. And roof suitability at 42,970 with a difficulty of 20, which is pure research-stage demand from people trying to work out whether their house even qualifies. Almost nobody in your sector serves either properly. Section three covers both.
How should we handle savings and payback figures?
As illustrations with the assumptions named, never as facts. State what changes the answer, meaning orientation, shading, usage pattern, tariff and system size, rather than publishing a single payback period. That is a compliance position and a conversion one at the same time, because your buyer has already seen the optimistic version elsewhere and discounted it. Never mark savings figures up as structured data either, since structured data is read as an assertion. Sections five and eleven cover it.
