Home Solar Power Monitoring System

Background My father and I decided to install photovoltaic (PV) panels at home to help reduce our electricity costs. After installation, it was difficult to know exactly how much energy was produced by the system and how much savings we actually made. Most of our estimates were only rough guesses. To solve this, I decided to build a system to monitor our power usage and generation. This project also became a hobby that I truly enjoyed working on together with my father. Web Application I developed a fullstack power monitoring web application using Next.js. The system exposes an API endpoint for posting sensor readings collected by our sensors. On the front end, the dashboard presents real time and daily summaries of electrical data, with some key features: Daily Report: Displays a graph of grid, PV & battery, and inverter power usage over a day. It also displays electricity statistics (total energy, power range, voltage range, etc.) for grid, PV & battery, and inverter. Monthly Report:
