Solar Company Website Design

Nobody books a solar survey on impulse. A homeowner notices panels on a neighbor's roof, checks a few energy bills, reads three installer websites over several weeks and only then asks for a quote. On a commercial roof the same decision passes between a facilities manager, a finance lead and a managing director. A solar company website has to meet each of these people at the right stop on that long road.

This guide covers the decisions behind a solar installer's website in the order they come up: the quote form, uploaded bills, an honest estimate calculator, rules on green claims, certification, project pages and aftercare. Every section ends in something you can act on.

01Build the site around the buyer's research timeline

The structure of the site should follow the stage the visitor is in, not the list of services you sell. Someone researching solar for the first time does not want a quote; they want to know whether their roof is suitable, how complicated the process is and whom to trust. Each of those questions needs its own type of page.

• Curiosity stage: a plain guide to suitability, covering orientation, shading and the condition of the roof.
• Comparison stage: solution pages per install type, plus finished projects.
• Decision stage: the process page, the maintenance offer and a quote form built on the energy bill.
• After the install: service requests, monitoring help and periodic checks.

Every page ends with one clear route to the next stage. A visitor who has just read the suitability guide is better served by projects on similar roofs than by a quote form. The home page shows all four doors and lets visitors pick their own stage.

This is the same decision order we use across every industry in our web design service, adapted to solar. The difference is the length of the cycle. Many visitors return weeks later, so the site should let them pick up where they left off.

02Separate doors for homes, business roofs and land

Explaining three install types on one page means losing three different decision makers at once. A homeowner thinks about the household budget and how the roof will look. A business owner asks about the usage profile and whether installation will disrupt operations. A landowner or investor cares about project management and grid capacity.

Each door needs its own language, images and form. A close shot of a real house roof sets the tone on the domestic page, an aerial view of a warehouse roof on the commercial page and a site preparation photo on the ground mounted page.

• Domestic page: roof suitability, the questions households ask most, what installation day looks like and aftercare.
• Commercial roof page: usage profile, how roof load capacity is checked and a plan for working around operating hours.
• Ground mounted page: land suitability criteria, project management stages and a contact route for investors.
• Battery storage page: the usage patterns in which adding a battery starts to make sense.

A useful test: can someone reading one install type page make a decision without ever seeing the other two? If not, the page is still written like a generic services page. Name the pages in the buyer's words, such as "Solar panels for your home", and list all three under "Solutions".

03Design the quote form around your surveyor's questions

The quote form is the digital version of the questions your surveyor asks on the first call; a form with name, phone and message cannot do that job. The answer is to split the questions into short steps and let each step adapt to the previous answer.

1. Where: home, business roof or land. Later questions change with this choice.
2. Usage: annual consumption or a photo of a recent bill, rather than a monthly spend figure.
3. Roof: type, rough orientation, approximate area and an optional roof photo.
4. Location: postcode or town; the full address is taken when the survey is booked.
5. Timing: options such as "this year" or "just researching" show how warm the lead is.
6. Contact: phone, preferred call time and permission to use WhatsApp.

The timing question looks minor but changes how your sales team prioritizes. An information pack suits someone who is only researching better than a same day call.

Show a progress bar and a short "why we ask" line at every step. Next to the orientation question, a line such as "We use this for the output estimate; leave it blank if you are not sure" keeps genuine but incomplete requests from being abandoned halfway. A partial request from a serious buyer is worth more than a perfect form nobody finishes.

04Treat uploaded bills and roof photos as personal data

An energy bill is not an ordinary attachment: it carries a name, an address, an account number and a usage history. The moment you add a bill upload field, you are processing personal data, and the site has to handle it like that.

Put a short privacy notice right next to the upload, not behind a link at the bottom of the page. Say what the file is used for, how long it is kept and who sees it. For installers serving customers in the EU, consent is also required before non essential tracking cookies are set; plan the cookie banner and the form together.

• Storage: files sit in a protected area that only authorized staff can open, never in a public folder.
• Delivery: files reach the team through a dashboard, not as e-mail attachments; the inbox only receives a notification.
• Retention: files from requests that never become quotes are deleted after a set period stated in the notice.
• Alternative: anyone who prefers not to upload a bill can complete the form by typing annual usage instead.

Roof photos can reveal where someone lives. Before any image is published on a project page, strip the embedded location data (the GPS coordinates a phone stores inside the file) and confirm the customer's written consent.

05Build the estimate calculator with its assumptions visible

A calculator earns its place only when it gives an early idea that the survey will confirm, never a fixed promise. The fastest way to lose trust on a solar website is a single box where visitors type a bill and receive a precise savings figure; real output depends on orientation, shading, panel tilt and how the household or business uses electricity.

A good calculator shows the assumptions right beside the result. When visitors read "assumes a south facing roof with no shading", they think about how their own roof differs.

• Inputs: location, roof orientation, approximate area and annual usage, each with a "not sure" option.
• Assumption box: the tilt, shading allowance and system losses used, and the date of the tariff data.
• Result wording: "estimated", "early estimate" and "confirmed at survey" rather than "you will save".
• Next step: one button under the result that carries the entered details into the quote form.

Before launch, run a handful of your completed projects through the calculator with your surveyor and adjust the assumptions where results drift from what you saw on site. Visitors who first want to understand their own consumption can be pointed to the electricity cost calculator.

06Advertising rules for green and savings claims

Every environmental or savings sentence on the site is a marketing claim, and advertising rules apply to it. In the UK, section 11 of the CAP Code covers environmental claims: the basis of a claim must be clear, the meaning of the terms used must be clear to consumers, and absolute claims need a high level of substantiation. Claims should also reflect the full life cycle of the product unless the ad states otherwise.

For solar companies this hits common phrases directly. "Zero carbon energy" is an absolute claim; panels are manufactured, shipped and eventually recycled. "Slash your bills" without a stated basis leaves out material information. Other markets have their own consumer protection and advertising rules, so check them before you publish.

• Vague: "Clean, green energy that ends your electricity bills."
• Clearer: "Electricity generated on your roof covers part of what you use; we calculate how much at the survey."
• Vague: "The only fully certified installer in the county."
• Clearer: "We are certified for the systems we install; you can see the details and check them on our certification page."

A simple habit helps: for every green or savings sentence, note in an internal document the evidence it rests on. Sentences without evidence are rewritten or removed. Apply the same list to social posts, brochures and your sales team's phone scripts.

07Explain certification and connection in your workflow

Buyers most want to know what happens after they sign, and the process page removes that uncertainty. For installs in Great Britain, Ofgem's guidance on the export payment scheme (SEG) says that solar PV systems up to 50kW must be suitably certified, for example through MCS or an equivalent scheme, otherwise the SEG licensee is not obliged to pay for exported electricity.

Rather than summarizing regulation, describe how your firm actually works. Say which documents the customer prepares, which steps you handle and when the customer hears from you.

1. Survey: roof or land inspection, usage review and an outline design.
2. Design and quote: the system design and a written quote for the customer to approve.
3. Paperwork: certification, grid connection notices and anything the local network operator asks for.
4. Installation: scaffolding, the work on the roof and safety measures on the day.
5. Handover: commissioning, documents and setting up the monitoring app with the customer.

Instead of promising durations, explain what sets the pace at each step, such as network operator response times or missing documents. Mark every sentence that depends on regulation and add a "last reviewed" date at the bottom. For installs outside Great Britain, write the equivalent steps from your own local rules.

08Project pages as data cards that load fast

A project page should be a data card that visitors can compare with their own situation, not a handful of attractive photos. Showing the same fields in the same order for every install makes comparison easy.

• Basics: system size in kWp, install type, town or county and the month of commissioning.
• Equipment: panels, inverter, mounting system and battery if fitted.
• Challenge: one problem solved on site, such as shading, a shallow pitch or old roof tiles, and how it was solved.
• Images: the roof before, the installation in progress and the finished system; customer names only with written consent.

Image heavy pages slow down easily. Google rates LCP (how long the largest element takes to load) as good at 2.5 seconds or less, CLS (how much the layout jumps) at 0.1 or less, and INP (how quickly the page responds to a tap) at 200 milliseconds or less, measured at the 75th percentile of visits. Compressed modern image formats, lazy loading and reserved image dimensions cover the basics.

Customers who need a new roof before panels go on are better served by a roofer's site kept separate from yours; we explain how that split works on roofing company websites. You can check how your current site behaves on a phone with the mobile friendly test.

09A separate pack for commercial buyers and investors

On commercial roofs and land, the decision is made around a table, so the site should offer something people can bring to that table. Facilities asks technical questions, finance asks about process and risk, and the managing director asks whether your firm is reliable. A single page that tries to answer all three satisfies none of them.

We recommend a downloadable company pack for the commercial side. It turns the site's content into something that can be presented in a meeting, and a short form at download shows you who is interested.

• Company: certifications, team structure and how projects are managed.
• Technical: roof load checks, mounting system choices and a plan for working around operations.
• Process: the responsibilities of your firm and of the business from paperwork to commissioning.
• References: data cards from commercial projects of a similar size.

Give land investors their own short form asking for location, approximate land size and the stage they are at. Trade partner applications need a separate form too, or they clutter the sales list. A team page that explains the roles of project managers and site leads, with a direct contact for technical questions, shows commercial visitors your scale in concrete terms.

10Keep customers close with maintenance and monitoring

The relationship does not end at handover; the maintenance page is the steadiest source of repeat work and referrals. Panel cleaning, inverter faults and a drop in output are what customers ask about most after installation, and if your site does not answer, they look for another company.

The service request form should split by type of problem. Asking someone who sees an error on the inverter display for a photo of the code means the engineer arrives with the right part.

• Fault report: a photo of the error code, the installation date and the address of the system.
• Periodic maintenance: a booking request for cleaning and checks, with seasonal reminders.
• Systems installed by others: a separate assessment form for systems you take over.
• Monitoring help: a step by step page for customers who cannot get into their app.

Seasonal reminders sent by e-mail or text need separate permission from the customer. Servicing systems installed by other firms is a strong source of new customers, especially when the original installer has left the market. State which inverter brands you can service.

11Show up for install type and local searches

People search for solar along two lines: install type and place. Someone typing "commercial rooftop solar" and someone typing "solar panels for my house" should land on different pages, and searches that include a town or county should meet content about the area you actually serve.

Copying one area page and swapping the town name does not work. Each area page should show projects completed there, the roof types common in that area and which days your survey team covers it. With no projects in an area yet, skip the page.

• Guides: articles on roof suitability, battery decisions and maintenance intervals, written for the research stage.
• Google Business Profile: the business name exactly as in the real world, without added keywords; if you do not receive customers at your address, set a service area and hide it.
• Structured data: company details and FAQs marked up only with information that is visible on the page.
• Internal links: every guide links to its install type page, every project page to its own install type.

We cover the search side of this structure in our SEO service. Each page should be the single answer to a single search. Tie guides to the calendar too; maintenance topics should be live before winter and installation topics before spring interest rises.

12Measure a long decision cycle properly

In solar, a form submission is the start of a sale, not the result, so measurement should not stop at the quote request. To see which pages really bring work, you need to record what happens to each lead after it arrives.

1. Track form submissions, calls and WhatsApp clicks as conversions from day one.
2. Tag every request automatically with the page it came from and the install type.
3. Have the sales team mark each lead at survey, quote and contract stage.
4. Once a month, compare which pages produced leads that reached contract.

This view might show that the domestic page brings many requests while fewer commercial requests turn into contracts more often. A short "reason lost" option, such as roof unsuitable or budget postponed, adds useful insight. In search ads, Google's Quality Score combines expected click through rate, ad relevance and landing page experience; it is a diagnostic tool, not a direct input in the auction.

For seasonal campaigns, a dedicated rooftop solar landing page matches the ad without disturbing the main site. We build the campaign and its tracking together in our Google Ads management.

13Common solar website mistakes and better alternatives

These are the problems we see most often on solar company websites, and most are easy to fix.

• Stock photos of panels: glossy roofs from image libraries do not build trust; use your own photos, including shots taken during installation.
• A single box savings calculator: replace hidden assumptions and precise figures with an early estimate that shows its assumptions and leads to a survey.
• A home page full of brand logos: panel and inverter logos do not create trust on their own; explain why you chose the equipment on your project pages.
• One form for every request: give customers, investors and trade partners their own forms instead of sorting a single inbox by hand.
• A process page nobody updates: mark every regulatory sentence, review it against official sources at least once a year and show the review date.
• No aftercare on the site: describe maintenance on its own page with a service form, and include systems installed by others.

Most of these come not from design but from not deciding who each page is for. Asking "who reads this, and at what stage" for every page catches most of them before launch.

14Questions for your web partner, and the next step

The right partner wants to understand your survey process before making your site look good. We suggest putting these questions to every team you get a quote from.

• Will you build the quote form fields from our surveyor's questions?
• Where will uploaded bills be stored, who can open them and when are they deleted?
• Who sets the calculator's assumptions, and how will the result be worded?
• How will we see whether a request turned into a contract?
• Who keeps the regulatory sentences current when rules change?

We do not have a live client project in solar yet, so we show our approach on a live demo site linked on this page; our work in other industries is on our references page. You can compare packages in the web design pricing section, or get in touch to talk through the systems you install and the areas you cover. In that call we list your survey questions and send you a written scope and quote.

Three things on your side speed this up: last year's projects with photos, your surveyor's first call questions in writing, and the install type you want to prioritize. With those, most of the structure takes shape in the first meeting.
