We’re Lucas and Benjamin. Voltary began with our own investment decisions: Is solar worth it? How big should the battery be? And which electricity tariff makes sense?

With our experience in economic modelling and data analysis, we wanted to work it out properly. We questioned assumptions, compared scenarios and refined the model. At some point, we thought: this could help others make their own decisions too. That’s how Voltary came about.
