I managed to get my MPPT algorithm up an working this weekend. It was very neat to see the converter searching through the solar panels V-I curve by changing the duty cycle - the algorithm runs slow enough right now that you can watch it happening on the scope, with the edges of the FET gate drive jumping back and forth: 

I also re built the base all the boards were attached to over the weekend, it now has sensors on both the input and output of the power stage. Its a lot nicer and neater looking than the previous base: 

I had plenty of time and some moderate sun to test in, so I was able to shoot some footage of everything in action. I am editing it this evening and tomorrow will post it to make all the requirements for the hackaday prize!
