Unlike the Outdoor Camera , the other wyze cameras do not have built in batteries, so that is the first problem - most of the solar panels sold for security camera does not have a built in battery, and panel size all seems too small. A camera consumes between 2 and 4 watt so the solar panel has to be rated at least 3 times that amount, since the sun only shines 8 hours a day - so you need at least a 10 to 15 watt rate panel+battery, but most of the small ones are only rated 4 watt.

Almost all solar charge controllers has a USB power outlet -- so setting up a solar panel with a battery and a charge controller is not that hard - I have 3 of these setup with different size battery and solar panel depending on how much power I need, as they powers not only my cameras but also my landscape lighting and water features.

There is also Phone charger batteries with built-in solar panel, but the panels seems to be all too small (less than 1w) for continuous use and discharge of the battery.
