Solar

A solar installer with 5 install crews based in Amsterdam, serving the wider Amsterdam area and focused on home battery installation and smart energy management systems. Before working with us, 56% of enquiries came through Werkspot and similar paid platforms, where the same lead often went to three or four competitors. The goal was more exclusive quote requests, a lower cost per install and a pipeline the owner controls.

The challenge

Where the business was stuck

  • Solar buyers research for weeks, compare several quotes and are wary of pushy sales, so generic lead lists convert poorly.
  • Rebates, tariffs and incentives change often, and campaigns that aren't updated quickly start making promises that are no longer true.
  • Shared solar leads are often sold to five or more installers, making cost per sale far higher than the cost per lead suggests.
  • Peak season (interest will be high throughout 2026 as the end of net metering approaches, with ongoing demand for batteries after it ends) was not being planned for, so budget ran out when demand was highest.

The approach

Two services, one goal

We focused on Website Optimisation (UX/UI & CRO) and GEO (Generative Engine Optimisation), the two channels with the best cost per install for solar installation businesses in Amsterdam. Every call, form and chat was tracked to a booked outcome from week one, so every decision was based on revenue, not clicks.
