@skyfaller @c24h29clo4 however, running a single server from solar panels means that you're using additional resources to store the energy between availability and use.

From an efficiency point of view I believe you would be better off estimating how much energy your server would use, and putting grid-connected solar panels on your roof.

yes, it will go in a mix with non-renewable sources of energy, but adding more renewable capability means less need to run non-renewable plants.

resilience or a mobile server for local delivery of course is a different matter, but then the considerations are much different.
