PVGIS-backed solar comparisons beat manual calculator spreadsheets for homeowners.

Strengths
  • •PVGIS integration provides legitimate production estimates by location
  • •Side-by-side comparison of up to 5 panels with payback calculations
  • •Multi-language support across 9 languages for international users
Weaknesses
  • •Demo restrictions block PDF uploads and limit to static panel catalog
  • •Only rectangular rooftops supported excludes most real-world roof shapes

Post Description

Hello HN,

I built this tool to compare multiple solar panels for my rooftop and get a monthly energy production report based on input location.

Some notes:

- calculations are done using PVGIS

- the only supported rooftop shape is rectangular (for now)

- it's possible to upload a solar panel PDF datasheet or parse a URL containing the details but in this demo instance I only allow the access to a static catalog of ~10k solar panels (LLM inference costs :D)

Feedbacks are more than welcome,

Thanks!
