Power doesn't warn you.
Apsia does.

Apsia reads your satellite's power telemetry. It tells you how long your panels and battery will last, and whether the power is enough for your tasks in every eclipse. Apsia only reads. You decide.

Tested on 62 real satellites, with public data

Scroll to fly into the shadow

Built for what you fly.

Six answers for every satellite. The ones your orbit needs.

This is what shadow does to a battery.

One pass of a CubeSat, from public flight data. Half an hour without sun, on every orbit.

Start with one file.

Upload your telemetry export (Yamcs, COSMOS, Grafana or CSV) and read the battery report. Free, no account. Apsia only reads: it never sends a command.
