General Idea

The performance of solar photovoltaic (PV) systems can degrade over time, we aim to provide a tool to check the performance their performance. The user should input location, specifications of the system and its location. Out app will then diagnose if the performance if acceptable.

We created a web app that allows users to check the status of their solar installations by evaluating if the energy production is at a normal state. Our application aims at providing a quick verification of the monthly energy production of roof top solar panels. The user will provide the following input:

1. Location of the solar panel: address
2. Size of PV: area in m2
3. Capacity kWp
4. 12 months of production data

The app looks up the estimations from sonnendach, compares the the input and returns:

1. Location on map
2. Status: ok or not ok
3. Monthly comparison of actual vs. reference as a bar chart
