I have one PV panel that just work at special hours according to Schedule:PV_On I modeled it in E+ according to following context. But it works all the time And produce Electricity. Here the result= link text

Can you check whether it works correctly if you use, say, a PhotovoltaicPerformance:Simple object instead? If so, then please file a bug report and reference PVWatts.

@shorowit I checked it. But the problem is the same...all PVs work together at the same time and availability schedule doesn't affect the results.
