Small Computing on Solar
If you’re wanting to power a computer off-grid we highly recommend you read through the Small Computing on Solar (SCOS) handbook by Brian Chapaitis. It is up to date and geared towards minimum sized systems for running your computer in a remote off-grid village setting. It’s available online here: https://lingtran.net/scos
Global Solar Atlas
This website run by the World Bank provides color coded maps of yearly solar energy available in any location. If you choose the “photovoltaic electricity output” map and your location is green or blue, you may need more solar panels than our normal recommendations. https://globalsolaratlas.info/
