Tempest Hub Power Bank Solar Panel Power

I’d like to have my Tempest Hub powered by a Solar panel, with the solar panel supplying power to the Hub Power Bank. I need to move the Hub out of reach of 110v power to get better RSSI values. I can’t move the Tempest sensor because I want optimum wind position.

Does anyone have any recommendations for solar panels for this project? I know they should have a 5v output but how much current (watts) should I be looking for? Ideally it should have a mounting gimble attached.

Will the pass-through feature of the power bank be a problem as the sun comes up and goes down, or clouds pass overhead?

Any comments/suggestions would be appreciated.

the pass-through is a feature that allows the powerbank to power other devices while it is being charged. So you would actually need it. If you live in an area with long periods of dull grey days, you would need a panel that also is capable of charging the powerbank when there is no direct sunlight. You have to prepare for the minimum, which probably means a bigger solar panel. How big? I don’t know. One of those powerbanks with build in solar panel probably won’t cut it.

Perhaps buy a kill-a-watt meter and measure your usage ???

The current hub may be slightly different to the original hub and the readings on our usb meters have returned slightly different results. So if you use search on this forum for ‘hub usb’ or similar you will find this discussed in several topics. This comment probably shows your answer:

You could likely just get a 12V battery and a 12V solar maintainer kit, then use an inexpensive 12 to 5V buck converter to power the hub. Kit and converter less than $60. Just add the appropriate battery and enclosure.

I can confirm that one of my remote hubs is powered from a 12V supply using a 5V buck converter successfully. The buck converter came with 2 usb sockets which I simply plug the hub into. I use a 12v supply because then any voltage drop in the long wire is not an issue as the buck converter sets the voltage.
