Beginner: 12v solar cell to charge 24v battery and run 24v components
So I don't see it being able to charge the battery and provide enough power to run the equipment.


I think you know you've already answered your own question! Using the wireless station at less than maximum isn't going to save enough power to make this work, especially as the boost converter won't be 100% efficient. 7W maximum generated during daylight hours only, maybe 10W or 11W required all the time. And the battery charging circuits will also use up some of that valuable power.

You could use it to provide camera power during daylight but that's about it - at my electricity prices that would save you about £2 a year. I'd have to suggest that the economics just don't make sense.
