Up until now, billing for electricity was the job of energy companies. In “self-consumption communities”, this complex task now lies with property managers for the first time. Our aim was to actively simplify this task. That is why we developed an easy, automated utility bill on the SEL customer portal. This centrepiece of Smart Energy Link’s solution is simple, user-friendly and has been developed using the latest technologies, such as Python and Vue.js. It is based on the vast volume of data continuously supplied to us by the meters. The complex calculations surrounding electricity tariff models are processed in the background. With just a few clicks, you have a simple, transparent and user-friendly utility bill for the amount of sustainable electricity used.

Smart Energy Link’s specific needs were fulfilled by developing customised solutions in Python and Javascript. The system architecture has been designed on the principles of flexibility and expandability. The widespread availability of the Django framework in the Python world and the ease with which robust and performant web applications can be created with it were decisive reasons for choosing this framework for the back end. This choice of technology allowed for the implementation of a future-proof, performant and open solution that can be developed and operated cost effectively. At the same time, this also laid the foundations for further developments that had already been planned.
