What is the average cost for supplying a residential block with solar power panels?

I am going to renovate of my residential block in some environment friendly method; I would like to install a solar panel to meet electricity of my residential block which has three floors. According to my calculation, it would require around 1500 watt electricity to light my whole residential hall. So my question is what is the average cost for supplying a residential block with solar power panels? Any suggestion and advice will be appreciated. Thanks in advance and have a nice day
