Project Background
Germany's balcony power plant specialist scaling across EU markets
About Sunniva Solar
Founded in 2021, Sunniva Solar is a balcony power plant specialist serving countryside residents across Germany — with 2M+ customers served nationally. The company operates its own solar panel production facility in Eschwege, an owned logistics network enabling 3-day delivery, and teams distributed across Germany, Serbia, and the UAE.
The platform spans sunniva-solar.de plus 11+ marketplace channels (Amazon, Kaufland, Otto, and more), with massive expansion opportunity across EU markets where fragmented competition and slow delivery remain the norm.
My Role & Scope
The Challenge: Fragmented Solar Market
Buyers face complexity, distrust, and slow fulfilment across a fragmented EU landscape
Fragmented Brands
No unified comparison platform — buyers jump between dozens of retailers with inconsistent specs.
Complex Bundles
Panel + inverter + battery combinations confuse non-technical buyers.
Language Barriers
EU expansion blocked by German-only content and poor localization.
Low Online Trust
High-ticket renewable purchases need credibility signals competitors lack.
Scattered Warranties
Separate components with separate warranty policies — no unified tracking.
Slow Delivery
Competitors ship in weeks; countryside buyers expect faster fulfilment.
No Countryside Focus
Urban-centric retailers ignore rural DIY solar buyers and balcony renters.
Three Core Customer Types
Each segment has distinct purchase behaviour and configurator needs
Homeowner — Countryside Energy Independence
Countryside house owner seeking energy independence with a balcony power plant or small rooftop system.
