Solar Website Design: Sites That Show the Math and Book the Site Survey

Five jobs a solar installer's site has to do

A solar website is not a brochure. It is the place a cautious buyer goes after the door knock, the neighbor's recommendation or the AI answer, to decide whether you are worth an hour at the kitchen table. Each of these jobs should have a page or a feature built for it, and each should be measurable.

Getting buyers to the site is a separate job, covered on our solar marketing page. What AI engines say about you before they ever click is on GEO for solar companies. The website is where both arrive, so its facts have to match theirs.

The pages a solar company should not launch without

For service-area pages that are more than a town name swapped into a template, see our guide to service area pages. For a broader checklist, what a contractor website should include covers the basics every trade shares.

Trust details Texas solar buyers can now check

Texas SB 1036 brought residential solar sales under the Texas Department of Licensing and Regulation. Solar retailers and salespersons must be registered from September 1, 2026. Contracts must show registration numbers, name the licensed electrical contractor doing the install and give buyers a five-day right to cancel. TDLR's License Search lets anyone confirm a registration by name, number or ZIP code.

A website that shows those facts plainly wins the comparison against one that hides them. Put the registration number in the footer and on the credentials page, in exactly the form TDLR lists it. Name the electrician of record. Explain the disclosure form the salesperson will hand over before signing, so it is expected rather than alarming. TDLR's rules prohibit false and misleading statements, so the same discipline applies to every savings figure on the site.

• Do not present the expired 25D credit as available for new installs.
• Label calculator results as estimates and state the assumptions next to them.
• Use only real reviews; the FTC bans fake and AI-written ones and undisclosed employee reviews.
• Show the cancellation right where buyers will see it, not only in the contract.
• Keep a dated record of what each page said, in case a claim is ever questioned.

Fast pages for buyers comparing installers on a phone

Solar shoppers open several tabs and close the slow ones. A heavy hero video of panels at sunset costs you the visitor before it costs you anything else. We build on Next.js, which prerenders or server-renders pages so the text arrives in the first response, with images sized for the phone they land on and fonts that do not shove the layout around. The Core Web Vitals service explains the measurements.

Accessibility is part of the same job. Calculators need labeled inputs and keyboard support, charts need text equivalents, and color contrast has to survive bright sunlight on a driveway. If your market includes Spanish-speaking households, note that TDLR provides its disclosure form in a consumer's preferred language when it can; a Spanish version of the key pages is a reasonable next step, and Athena's Harmonia agent drafts one for review.

Why crawlers need the savings math in plain text

Many AI crawlers fetch raw HTML and do not run JavaScript. A December 2024 Vercel analysis found crawlers from OpenAI, Anthropic and Perplexity did not execute scripts at the time. A savings calculator that only produces text after scripts run is invisible to them, and so is every price range trapped inside it. The fix is simple: publish the ranges and assumptions as page text and let the calculator add to them, not replace them.

A fair note: a well-built WordPress site also serves HTML, so the platform alone does not decide this. Structured data lives in code on our builds: Organization, a LocalBusiness subtype, and Service with areaServed, all matching visible text. Google says there is no special markup for its AI features, so we treat this as ordinary SEO. The longer explanation is in JavaScript and AI crawlers and your site ranks on Google and is invisible to AI.

If the price range only exists after a script runs, as far as a crawler is concerned you do not have one.

Athena CMS agents with solar work to do

Every custom site we build includes Athena CMS, with plain fields for owners and AI agents that draft work for approval. For a solar installer, a handful of them earn their keep:

• Delphi asks ChatGPT, Google's AI answers and the others what they say about you, flags a wrong price or an old incentive claim, and drafts the facts and FAQs to correct it.
• Hestia keeps hours, phone, address and service areas identical across the site and listings, including holiday hours.
• Echo drafts replies to Google, Yelp and Facebook reviews, flags unhappy ones first, and places review quotes on matching town and battery pages.
• Prometheus finds questions buyers ask that the site never answers, such as orphaned-system service, and drafts the page.
• Iris handles titles, descriptions, social cards and structured data; Argus watches for broken forms and slow pages.

Nothing publishes on its own. You approve, edit or discard each draft. For how Athena compares with a typical plugin stack, see Athena versus WordPress.

Price, financing and the build from mockup to launch

Custom builds and rebuilds carry a fixed price from $1,750. A site with a customer portal, say for warranty claims and monitoring help, starts at $3,500, and a site with online booking or a multi-step estimate flow runs about $9,000 on our web design pricing page. 0% financing needs 25% down: up to 12 months on any project, 24 months from $15,000, 36 months from $20,000. A $9,000 site works out to $2,250 down, then $562.50 a month for a year.

   Launch with redirects kept

   Every old URL is kept or permanently redirected so existing rankings and links carry over.

When Wix or Squarespace is honestly enough

A new installer doing a handful of systems a year, mostly by referral, can run a clean site on a builder for a long time. Write the cost, credentials and process pages in plain text, avoid script-only calculators, and claim your listings. Our comparisons of Wix and Squarespace against custom builds lay out where each one stops.

A custom build pays when you sell in several towns, need booking or a portal, or compete with firms whose sites already show the math. To see what that looks like, browse the solar installer demonstration site DataCram built, a fictional company with a savings calculator and service pages. More trades are in home services website design, the full list is on the website design hub, and our wider renewable energy work is here too. Then ask for the free mockup and we will design your home page first.
