Thanks @geckoVN and @caius. Much appreciated. I have reached out to the Raspberry Pi foundation for my project as I was looking at using the compute module, and expand my project to more use. With the Pi 4 and some future development, my project makes more sense when combined. This got me into rethinking a few things. So far, I have settled on the following: combining solar, wind and hydro electric generation. My power sources will be installed where it make sense (wind on the cliff, water and solar panels at the base along with the batteries. Power to be sent up to the Pi(s… I may use 2) via PoE. And internet via Wifi using a Yagi to the building 250 ft below. I rigged a quick test setup with batteries to make sure my concept could work, and works fine. With all of the power manage being on terra firma, I don’t have a space and weight constraint. A 50ft run of cat 6 ethernet to bring electricity and ethernet is now making a lot more sense to me/ Making the setup more stable and flexible. At the end of the pole would be the antennas, a camera case, and weatherproof case with the PI(s). It should be lightweight and slim enough to sustain high winds without too much problem. I will setup an empty box with water damage detection strips for a little while to confirm my setup makes sense in terms of location, anchoring, etc. While I am sourcing and planning the rest of the setup, this should provide valuable logistic information.
My second location is in the arctic, I will solely use wind and hydro as my power source there. Only difference other than that, would be that the internet link would go directly to the Pi instead of heavier box were batteries are to be located, and use a BBQ grill directional antenna, for a 3 mile link. I have a similar setup workin, so I know my internet access is not the concern here. anchoring in the mountain.
I’ll try to document my progress and setup for those interested.
