Agreed adding more panels would work around the limitation. The reason I ask is that in theory there is room to reach upwards of 48%, the max being reached right now is around 32% and all the panels I can find that are mass produced are between 20% and 22% assuming one can even find the numbers, some companies are making the numbers hard to find. Anything above 22% appear to climb in cost exponentially.

With more panels my setup will be more of an eye-sore, require more and longer cables, combiner boxes and the setup becomes a bigger project. So I am just being a selfish ass but I had to ask where we are.

Multijunction solar cells (the ones that can get over 30% efficiency in theory or 25% in practice) are a completely different market. They generally go into satellites and research labs, not rooftops and power plants. That's why the numbers are hard to find.
