On the solo.ckpool.org website it says:
All you need to confirm you are mining to your own address is to examine the coinbase and template sent to you over stratum.
Just out of curiosity, could someone tell me how I can confirm this? i.e. how can I examine the coinbase and template sent to me over stratum?
I'm running an S9 solo. Just testing my luck

I believe there may be online tools to do so, but you can do it yourself with the latest version of cgminer and your own bitcoin daemon, using cgminer's --decode option. The instructions are with cgminer and in one of the last posts on the cgminer thread as well, but you'll need a linux box and a bit of know how to get it going.
