I have read the replies above, people being worried about that system is only generating 1.2KWatt during peak timings.
Let me explain this, if your solar panels are correctly mounted, which implies that it is pointing towards true South, then above scenario could be because of two reasons.
Optimum solar angles varies throughout the time of the day and the month. For example, the optimum solar angle during summers in Pakistan is around 17degrees whereas the same angle during winters is around 50 degrees, so mostly in Pakistan, Solar mounts have a fixed angle, its very difficult and time consuming task to change the angles. Secondly the installers here have very little clue about the correct orientation of solar systems, i mean to say is, that most of the people make mistakes here. Further, during summers, once temperature rises, this degrades the performance of solar panels, so output from solar panels has lot to do with surrounding temperature.
