In 2016, Fortum made a decisive move toward clean energy — not just as a vision, but as a product you could buy, install, and understand. Solar panels had been available for years, but the experience around them was fragmented, jargon-heavy, and hard to navigate for ordinary homeowners. The opportunity was to rethink the entire journey from first curiosity to panels on the roof. We joined a multi-vendor design team embedded at Fortum's headquarters in Espoo, working alongside Fjord, Ixonos, Futurice, and others as one integrated team inside the organisation. The focus was clear: build digital services that make solar energy feel obvious, not intimidating. The work covered three connected experiences — a redesigned marketing website with a solar benefit calculator, and Fortum SODA, an order and delivery platform serving customers, Fortum staff, and third-party installers. The result was a coherent, end-to-end solar experience that made Fortum competitive in a market it was determined to lead.
