Solar panels and Ekodomes.
Yes, with a ground mount system.
At the moment, there isn't an easy way to add solar panels to the frame. Customizing a DIY solution is always an option, but it may be a better solution to incorporate a ground mount system with your dome.
Solar panel systems work best when all of the panels are on the same "plane" and aimed directly (or as close as possible) at the sun. Panels at the various angles in a dome would not be as efficient.
