I have got a four bedroom apartment in the suburban city in the state of Arizona. There are too many power cuts in my area these days. I am planning to buy some power back up for my home. One of my friends recommended me to buy solar power system for home. So, I am planning to get it installed in my home but I am bit anxious about the cost of such home solar power system. So I want to ask the people who have this system installed in their house about how much would home solar power systems cost? I would really appreciate your replies. Thanks.
