Is it possible to link different solar arrays to different energy usages in the one project, For example, if I had 3 buildings next to each other, each with different energy requirements, and an mpan in each building, when creating the consumption data could I have energy usages; Mpan 1, Mpan 2, Mpan 3, and then 3 different sized solar arrays to be appropriately sized for these individual Mpans? This way I could more appropriately size the system based off of the energy needs Cheers,
