How bad is your shading issues? Have you received any quotes? I am not very familiar with the OptiTrac Global Peak technology so unable to comment but could research it if required. Which state are you in?
OptiTrac has been around for a long time. Despite the very nice marketing video that SMA has about it, from the limited info that I’ve heard about it, it does not sound like it makes a big difference in the real world. I haven’t heard any installers suggest going for an SMA Sunny Boy because of it.
If you’ve got serious shading issues, I think you should look at panel level optimisation (Tigo, SolarEdge, Enphase). There are a few people on this forum that are big proponents of Enphase, and argue that they will offer you the best return on investment long term. There’s many others who strongly back Fronius.

I appreciate and respect that you do not want anymore quotes. The only reason I mentioned it was because our prices for the systems you mentioned would be $5,550.0 for option 1 and $5,300 for option 2.
Wishing you the best and hope you enjoy your new solar system.
