Sunline
Marketing site and lead-gen funnel for a solar-installation company in Nouvelle-Aquitaine, with tiered offers, a project simulator, and a map of completed installations.

The context.
Sunline installs residential solar across Nouvelle-Aquitaine in a market thick with aggressive door-to-door sellers, so the entire job of the site is to make a homeowner trust them before a salesperson ever calls. That means making the offer legible (what you get, what it costs, what the aids cover), proving local track record, and giving people a way to self-estimate without handing over a phone number on step one.
What shipped moved.
- 380+
- installations mapped
- 3
- configurable offer tiers
- Live
- project simulator
Built a Next.js multi-page site structured around the actual product ladder (SUN Essential / SUN Confort / Tesla Energy) with configurable power tiers in place of vague 'request a quote' boilerplate. Added a project simulator that produces a real estimate, a Leaflet map plotting every completed installation by town so prospects see work near them, and partner-brand logos (DualSun, Huawei, Enphase, Tesla) as credibility anchors. Local schema markup and town-level content for SEO across the La Rochelle–Royan corridor.
What happened.
Sunline now reads like the established regional specialist it is, not another anonymous solar reseller.
The configurable offers answer the price question up front, the simulator lets a homeowner reach a number on their own terms, and the installations map turns 380+ past jobs into proof that's specific to the visitor's own town.
Overview.
Designed and built the website for Sunline, an RGE-certified solar installer serving the La Rochelle region. The site presents the full offering (self-consumption panels, battery storage from Huawei and Tesla Powerwall, maintenance) through tiered, configurable offers (3/6/9 kWc), a project simulator that turns a roof into an estimate, and an interactive map of the 380+ installations completed across Nouvelle-Aquitaine. Every path routes toward a single quote-request flow.
