Clean Energy Toolkits' Origin

Once upon a time in 2021, Stefanie, an accomplished electrical engineer, along with her family, transitioned from northern Germany to the sun-bathed coasts of Florida. Boasting a decade-long immersion in the clean energy realm, she was poised to advance Florida's energy narrative. Yet, the scarcity of rooftop solar installations in stark contrast to the state's sunny disposition dumbfounded her, especially given Germany's wide acceptance of solar power.

​

Her rigorous doctoral research had already ignited Stefanie's zeal for clean energy, providing her with keen insights into homeowners' inclination towards solar systems, battery storage, and electric vehicles, among others. Interactions with Florida's residents unveiled an unsettling truth: a tangible knowledge void marred by obsolete information and experiences of inferior installations. This revelation propelled Stefanie to launch 'Clean Energy Toolkits', offering a clearer, more accessible pathway to solar energy. A pivotal outcome of this endeavor was the state-of-the-art solar calculator, Sunny.

Stefanie's unparalleled commitment to quality and breakthroughs is mirrored in her accolades and an esteemed affiliation with the CNV Foundation of Nobel Laureate Christiane Nüsslein-Volhard. Moreover, her profound studies on PV system integrations, heat pumps, and electric vehicles in low-voltage grids, and the promise of demand side management, are testament to her forward-thinking approach.

Today, under the banner of Clean Energy Consultancy, Research, and Development, Stefanie and her proficient team proffer bespoke clean energy services, including smart grid analysis and strategic planning. Abiding by their motto, "Our world. Our impact. Your choice," they beckon you to partake in this renewable energy expedition. Embark on your personalized clean energy journey with Stefanie's guidance.
