Internship through "Fem in Tech"

11.09.2025

As part of TU Graz’s “Fem in Tech” program, Anja and Tuana completed a four-week internship at our institute.

Supervised by Simon Malacek and supported by Felix Auer and Marco Montero, they independently studied the basics of energy economics and collected real-world data, including average PV system costs, capacity factors, electricity demand time series, energy prices, and potential feed-in tariffs.

Building on this, they developed a Python tool that calculates grid consumption, feed-in, and total costs – including annualized investment costs – in hourly resolution for an entire year. The tool automatically identifies the most economical solution for different numbers of PV modules.

In two case studies, Anja and Tuana also demonstrated how different feed-in tariffs affect the optimal system size.

We hope this project provided them with a positive insight into the diverse opportunities technology offers – and that they might return to TU Graz in a few years for their studies.
