Solar arrays, from the advanced machines addon to industrialcraft, condense multiple solar panels into one block, producing more power but with smaller space requirements.
Low-Voltage Solar Array
The LV solar array is made from eight solar panels and an LV transformer. It outputs 8 EU/t when it is sunny, the sum of the solar panels it is made of.
It is not adviced to connect more than 4 of these to a copper cable.
Medium-Voltage Solar Array
The MV solar array is made with 8 LV solar arrays and an MV transformer. It is made of a total of 64 solar panels, and outputs 64 EU/t.
It is adviced that a player makes a quick search for old copper cable in his home's power grid before installing one of these in order to qvoid costly reparations after an old piece of copper cable melted.
High-Voltage Solar Array
The HV solar array is made with 8 MV solar arrays and an HV transformer. It is made of a total of 512 solar panels, and outputs 512 EU/t.
