I'm not sure where to report this as we have multiple mods going on here:
We were playing with build 645 of ic2 and advanced solars 3.5.1 with Gravitation suite 2.0.3 and encountered this:
This setup was giving us over 46k eu/t when it should have been like 7k eu/t.
Clearly something is wrong with cables or solars or the molecular assembler but we lack the knowledge to track down what. Seems also to be dependant on the direction how the solars are placed (north/south/wet/east)
