$100M Solar Empire Case Study | Digital Growth by Upsworth

Scaling a
German Solar
Brand to €100M
in Sales

A fast-growing German solar energy company approached Upsworth with a vision: to establish a strong digital presence, expand across e-commerce channels, and scale sales in Germany’s competitive renewable-energy market. At the time of engagement, the company had zero online presence, limited marketing resources, and no streamlined sales or logistics process.

Our Role

As a complete end-to-end IT and growth partner, Upsworth managed the project for 3 years, covering every digital and operational touchpoint:

Website & Technology

Designed and developed robust, scalable websites optimized for sales conversion.

Performance Marketing

Managed Google Ads, Google Shopping, and campaign planning across German digital channels.

E-Commerce Expansion

Listed, optimized, and scaled presence on Amazon, eBay, Kaufland, Otto, Netto, and other German marketplaces.

Creative Assets

Produced engaging graphics, videos, and ad creatives tailored for the German market.

Social Media Marketing

Built brand awareness and customer trust through targeted campaigns.

Customer Support

Delivered German-language customer service to ensure smooth communication and trust building.

ERP & Logistics Integration

Streamlined operations by managing orders, inventory, and fulfillment with ERP systems.

Strategy

Upsworth combined data-driven marketing strategies with a deep understanding of German consumer behavior.
Key elements of our growth strategy:

Multi-channel presence
Diversifying across all major German e-commerce platforms.

Localized marketing
German-language campaigns, customer support, and culturally relevant creatives.

Full funnel optimization
From brand awareness to retargeting, ensuring consistent conversion uplift.

Seamless operations
ERP-backed logistics to handle large-scale order volumes efficiently.

Sustainable scaling
