You just need a bit of patience at the beginning. I highly recommend using IC2 with Applied Energistics mod's ME network. Once you get things rolling, you can simply tell the terminal to craft 1 MFSU and it does all the parts and ready product for you. It is a little bit fascinating watching the crafting monitor for all the little things it does for bigger projects, but also at the same time be satisfied for all the systems you have built for it to work.
Also i'm a fan for solar panels, so Advanced Solar Panels mod was essential
[Addon v1.118, v2.0 exp for MC 1.6.4] Advanced Solar Panels v3.4.6 + Quantum Generator + Solar helmets ![SSP/SMP]
You'll come to see how difficult it is to build even 1 hv-solar panel in vanilla way (yeah that may be from "compact solars" mod, but doesn't every modpack have it?).
