I just installed the latest Compact Solars build with IC2-experimental build 153 and it works.
I have a suggestion relating to how it interacts with the new energy nets. Since EU are now additive instead of packetized, it would be best to have the panels output a constant EU/t. I'm sure this behavior is a holdover from the previous packetized EU system, but it seems that the LV panels, for example, output 32 EU during 1 tick and 0 EU during the following 3. With the new energy net, this means that if you put one LV panel on a machine, that machine only receives 8 EU on average (as it should, since it takes 8 solar panels to craft it). But when you put two LV panels on one LV machine (expecting to get 16 EU/t, still within LV specs), the machine explodes because it got 64 EU during one tick, never mind the next 3 ticks were going to be empty.
As it is, to get a continuous 32 EU/t into a machine you have to have them combine four of them into an MV feed and go through an LV transformer, which you didn't have to do before.
