My organisation
SUNBOOSTER GmbH, based in Graz, Austria, develops innovative PV energy solutions that maximize self-generated power for households. The POWERSTATION GRID+ is the first plug-in storage system for balcony PV, allowing surplus energy to be fed into the grid and significantly reducing electricity costs. It is expandable up to 10kWh, offering flexibility for different energy needs. Sunbooster VERTICAL transforms garden fences into PV power plants thanks to its bifacial, flexible PV stripes. It therefore increases energy yield while serving as a functional and aesthetic alternative to traditional visual protection strips of metal bar garden fences.
With strong market demand regarding POWERSTATION GRID+ and substantial pre-orders already secured for Sunbooster VERTICAL, SUNBOOSTER is seeking investment and/or strategic partnerships to accelerate product expansion and market entry in EU. The company has a scalable business model combining hardware sales with recurring SaaS revenue and is profitable since years. Its direct-to-consumer strategy through Amazon, Shopify, and B2B partnerships ensures broad market accessibility.
SUNBOOSTER’s solutions support EU climate goals by making decentralized energy storage and self-sufficiency easy and affordable for consumers. Positioned for rapid growth in the European renewable energy sector, the company offers a compelling opportunity for strategic investors looking to scale innovative solar solutions.
