Any usage for Solar beyond 4 x 3 (max) skill upgrades?
Just about at least 1 in 10 of my (lowish ranked) Awesomenauts matches becomes a rather long game, where I easily reach the point where I've upgraded all 4 skills three times. Like this Swoop game:

In the screenshot my money was 504, but at the end of this game it was 1200+. Is there any way at all to utilize Solar after you've already bought 4 x 3 upgrades?
The Solar entry on the Awesomenauts Wikia holds no relevant info, nor does any of the pages in the Solar category. I've tried searching in the UI if there's anything I could do with the money but no dice. However, coming from dota-2 (where it rarely happens that you have no way to spend gold anymore), I feel like I'm missing something...
