Solars are on my short list of things to do first, yes. They are perfect candidates for the AE MAC and the ME Interface crafting/process interface/feature.
Shortly after I encode the 3x3 crafting tables recipes, I'll encode the coal dust, glass, rubber, etc.,. recipes and toss them in ME Interfaces on top of up-transformed and overclocked IC2 machines and put ME Precision Export buses below set to stack mode. That's the only time/reason I ever have for IC2 machines.
Even with all of that maxed out (8x MFSUs into HV-Transformers in reverse mode feeding 2048 EU/t to 4x Insulated HV Cable), a High Voltage Solar Array takes a while to build.
It cuts down on the time a lot if I 'prime' the pump by ordering up thousands of the machine-processed required parts. The only assembly should then be 3x3 grid work.
I'm not a fan of IC2 in general, but I do like the ability to overclock and I like the sounds of the machines. The sound might create lag in a large machine farm, but 1 souped-up machine of each type isn't bad. It's pretty cool to have thousands of glass, coal dust, rubber, and compressed metal alloy / carbon plate all being made at the same time.
