We are the technical team that operates the cardano2vn.io project - which brings Cardano’s documents to Vietnam in the local language.
Team members are electronics engineers and system managers. We have created a stake pool C2VN that runs entirely on solar energy. Our detailed stake pool configuration is:
03 x Raspberry PI 4 Model B (02 Relays and one Block Producer) each node often consumes 6W/h. All 3 nodes need 18W/h for their operations.
01 Router and embedded switch: 1.5A/12v = 18W/h
01 Solar Pannel 150W/h
01 Battery 100A/12v=1200W
These are the pictures we took when setting up the project: 03 nodes

C2VN is running on very low power consumption infrastructure. Staking to C2VN means you are supporting carbon-neutral blockchains
Nice one! Quick question though, as those PIs come with a max of 8GB of RAM. Are you using SWAP to overcome the limitation based on the nodes now using around 12GB of RAM?
What sort of parameters have you used for the node and ZRAM?
Most of the documentation available online is now talking that is not possible to run a node with 8GB of RAM. I had a few attempts as well and the node keeps crashing, even with ZRAM enabled.
