I am the current maintain of the firmware for this project. Recently, I've been doing development for it using the LILYGO TTGO ESP32 dev board (V2.1_1.6) https://www.aliexpress.com/item/32915894264.html?spm=a2g0o.p... Therefore, power consumption specs should be similar to this board.

We are working on a new board design with an integrated solar panel and two LoRa radios, but I am less involved in that part of the project, so I can't answer all your questions on the power system. Perhaps this link will help, though it has not been updated for the ESP32, https://github.com/sudomesh/disaster-radio/wiki/Power

Currently, it does not have a sleep mode, I recall there being some concerns with waking up from sleep mode back when I was dev'ing with the ESP8266, not sure if that has changed on ESP32, have not re-approached the idea it since switching to ESP32.

We did have some do some tests with an off-the-shelf 15W solar panel and a super-cap, it seemed to work well. Check out their report, https://sudoroom.org/pipermail/disasterradio/2019-December/0...
