    Thanks for the data, Our site has much more exposure to sun than in a redwood forest, and  is doing something similar:
    https://monitormywatershed.org/sites/SpokaneR-SpokaneValley/

    Note the times on the website are accurate but when you look at the data the times are not accurate — sun isn’t up at 5am. I wonder why the clock reset..
    The last transmit via cell was 2:45 pm on 11/27. Yesterday Nov 28 was a full sun day all day…so it seems that that solar panel doesn’t run anything, all it does is charge the battery, and the battery never got charged enough to transmit via cellular.

    We have version 1.1 boards.
    The cell module says SimCOM – SIM7080G, P/N S2-108HB-Z308J
    Our only sensor is a Hydros 21 CTD.

    It sounds like the bigger solar panel might do the trick. I also saw in another discussion going to a 6600mAH battery. So this panel https://voltaicsystems.com/10-watt-panel-etfe/ with this battery https://www.amazon.com/dp/B0137IPVY6. And get the battery charged at home via usb before bringing it out into the field.

    Though for the good of the order I wouldn’t mind also trying 4 AA 1.5v energizer lithiums into the usb port and see how long they last. Something like this https://www.amazon.com/dp/B08P1L6JQT with a usb adapter https://www.adafruit.com/product/4536.
