How much do solar panels cost?

I’m doing a science fair project. I need to know how much a complete solar home would cost (switching from electricity to solar panels). My school is 215,000 sq. ft and our school annually uses 3,525,669 KWh. Where can i find how much that would cost? I’ve gone to several websites such as BP and i cannot find the answer. please help!
