Battery: 99%

I have a solar-powered website at solar.dri.es (mirror). It runs on a Raspberry Pi with a solar panel on our roof deck.

Every 10 minutes, the Raspberry Pi updates this status page. This page is hosted separately, so if my solar-powered website goes offline due to an extended lack of sunlight, cold preventing the battery from recharging, or a system crash, you should be able to see that here.

A green square means the battery is well-charged and can power the Raspberry Pi for several days. A red square indicates the battery charge is low and requires solar charging soon. A grey square means the Raspberry Pi was offline.

This graph displays the battery's highest (green solid line) and lowest (red dotted line) charge levels each day. It helps track trends and assess the risk of the Raspberry Pi shutting down due to insufficient sunlight or extreme temperatures, which prevent the battery from charging.
