What do you mean? A 2.5kW array will produce 2500W of power when the sun is at 90 degrees to it. This never happens to me, so I get less, 1,200-2,000W output depending on season and time of day. Now, in october, the array at best produces 1,400W, but the graph itself is sinusoidal, so the net power produced is 7kWh. Different units here - kW (which is specific power) verus kWh, which is power used.
