The technology is moving so fast, surely it’s worth waiting for new panels?

There are advances in technology, however these are aimed more at using different materials, e.g. hiding PV technology in glass. These advances do not show any progress in efficiency so are unlikely to become mainstream. The technology we see in today’s Solar PV panels is the same technology that was used to power some satellites in the early 70s. There are some small incremental advances but these are not expected to change dramatically at the moment.
