Solar Ikea Blinds?

I’d like better blackout blinds in the bedroom, so I’m thinking about getting Ikea smart blinds. However, one of the windows is weirdly shaped and the battery would be inaccessible. I’ve heard @RosemaryOrchard talk about both Ikea blinds and solar charging - have you got them working together?

Also, are there affordable non-Ikea smart blind options? Ideally I would like double-cellular blackout blinds for some noise-dampening in addition to the blackout.
