Web Application Development for Solar Installers.

Web apps and complex sites that do real work, not just look good. Designed and shipped for solar installers, not generic templates with solar installers swapped in.

Why this matters

Why solar installers need Web Apps built around their unit economics.

Most solar installers are operating on sites or software stacks built three to five years ago for a different version of the buyer. Proposal and system-design tools don't talk to the CRM, so reps rebuild the same customer data three times per deal. The infrastructure decisions that compound are the ones made with the operator in the room, not the ones made in a vacuum.

Inparlor's Web Application Development engagement for solar installers reflects that. We build web applications: customer-facing apps, internal dashboards, data-heavy portals, and complex content sites that go well past a brochure. The deliverables below are scoped against the unit economics, avg install ticket of $20,000-$45,000.

Where most agencies treat solar installers as another vertical to learn on, we treat the vertical as the starting point. Long 60-120 day pipelines run on spreadsheets, so prospects go cold between design, financing, and install. We will tell you on the first call which of those constraints is binding and which is solvable inside the engagement.

Our Solar Installers-specific approach

How Web Apps runs in solar installers, operationally.

  • Redirect map on day one

    Even brand-new sites have legacy URLs to honor, orphaned PDFs, archived blog posts, vendor microsites. Missing a 301 is how organic traffic dies on launch day, so the redirect map is week-one work, not a launch-day checklist.

  • Performance budget held through deploy

    Largest Contentful Paint under 2 seconds on a 4G mobile connection. Cumulative Layout Shift under 0.05. We hit it on every preview deploy, not just at launch, and we keep hitting it for 90 days after.

  • Editorial workflow, not a CMS dump

    We default to Sanity, Contentful, or MDX-on-GitHub depending on team size. Editors get a workflow they will actually use, preview environments, scheduled publishes, and roll-back if anything breaks.

  • Measurement wired before the homepage is approved

    GA4 events tied to revenue, not pageviews. Meta CAPI on day one for any site that will run paid traffic. The dashboard tells the truth before the brand approves the design.
