Not exactly what you’re asking for (at least price wise), but there are solar power adapters for trail cams: https://www.basspro.com/shop/en/tactacam-external-s

  Yep, I've seen solar trail cams, just none that have a setting for taking a picture at the same time each day. I expect if you eliminated the need for taking video and motion detection, should be able to get away with smaller panel and battery. Most trail cams also have IR modes, don't need that, which would drop cost as well.

    this should work as long as it supports charging while in use (hook up solar panel to usb and done): https://www.brinno.com/time-lapse-camera/TLC120 https://www.brinno.com/time-lapse-camera/TLC120 Or roll your own: It's overkill, but lots of solar-powered battery-backed raspberry pi systems out there. If it only needs to run for a few minutes/day. You can undersize the solar if you can skip cloudy days when there's not much growth anyway. Maybe an old laptop with webcam or some digital cameras with 'remote' triggers could fill the role. An RTC chip with alarm function could send a power-on signal every day and at least a pi can self-shutoff once the job is complete. "Not all RTC chips have alarm functions but a few that do are the DS3231 (Maxim Integrated), MCP79410 (Microchip) and ISL12026 (Intersil). Here, a DS3231M is used to construct a simple, but fully functional, RTC building block and, further, to construct an example RTC-based switch." https://www.allaboutcircuits.com/projects/build-programmable-time-based-switches-using-a-real-time-clock/ https://www.allaboutcircuits.com/projects/build-programmable...
