If you "lack the skill to install" it yourself, then you don't get to complain about "very greedy middlemen." If labor really WERE super expensive and they were greedy, then you could afford to learn the skills and install yourself. Nah, don't expect labor costs to be free or expect labor to be paid below a livable wage. Or heck, don't expect labor which is more skilled than you are to be paid less than you are.

But this is an important point: residential solar will always be fairly expensive due to labor costs. As module and other hardware costs reduce, it'll make sense to use the very highest efficiency cells, tracking systems (provided they're simple to install), etc.

But I think utility and commercial scale solar will dominate. Someone will eventually get really good at installing solar farms a gigawatt at a time with a highly automated system. Think of the harvesting and planting machines we use in agriculture. Or the machines used to lay railroads automatically. When this happens, utility solar at the interconnection point will drop well below 1 cent per kWh in sunny locations, and transport costs will dominate. Which has some interesting implications.
