Welcome to the Forum, @krasmussen68! 
I think the answer is probably that you can’t unless you’re providing power with a 5V ⎓ 2A adapter.
Your post reminds me of another recent Forum topic, and in both cases I imagine Wyze has made the decision to limit streaming in order to preserve/prolong life for the non-user-replaceable battery. Even the Wyze app is limiting my use on a battery-powered Cam right now: I’m currently using a Duo Cam Doorbell in battery mode, and if I leave the app open to watch the Cam’s live view, after two minutes it pops a warning and asks me if I want to continue viewing the live stream. This device even has swappable batteries, so it’s not under the same design constraints as Solar Cam Pan.
My understanding with both devices is that providing power from an AC source (using the adapter as noted for Solar Cam Pan or using a typical low-voltage AC doorbell transformer for Duo Cam Doorbell) will enable both to continuously record to microSD (in contrast to events-only recording when battery powered), and I would expect this also to enable uninterrupted streaming. I’ve read user reports that this is the case for Duo Cam Doorbell, but I haven’t yet tried this myself.
