What will be the genuine price to be paid for solar power?

I am very much worried about Global warming, so to contribute something for reducing Global Warming I have decided to use Solar Panels. I want to know how much it will cost me to be off grid and completely be green power I am looking for solar power and I am looking for 20kva system for my home but I am confused because there is no fix rate and I like to know which panel is the best in the market today and its cost. Any feedback will be appreciated. Please help.
