Battery
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.

Daily battery levels
Each day's highest and lowest charge. It helps track trends and the risk of the Raspberry Pi shutting down from insufficient sunlight or extreme cold.
