That sounds like a solid plan. Keep the power budget tight – a single panel and a small battery means you’ll need to push every watt. Stick to low‑profile components: a single board computer, maybe an ARM server, and a solid‑state drive. Use a DC‑DC converter that’s 95 % efficient, and run the OS with a minimal kernel. For the network link, a low‑power Wi‑Fi or a narrowband LTE module will keep the ping alive without draining the battery. Don’t forget to set up a watchdog that resets the system if the connection drops. And remember, the fewer moving parts, the less that can go wrong. Let me know the exact specs and I can run a quick load test.
