Cory, The PV models in TRNSYS (Types 94, 180, and 194) are a little odd in that they output both a "power at max power point" and a "power at load voltage." Its a bit like modeling two pvs at once since the outputs are completely separate from one another. In most grid-connected applications, you would use the power at max power point because the PV would be connected to the grid through an inverter/max power point tracking device that makes the PV "see" the best possible load. You use the "power at load voltage" in direct connected or all-DC systems where the PV is directly connected to a load that is operating at a particular voltage (for example if you have a PV connected directly to a pump, the load voltage would be the pump voltage).
