How feasible is my idea on clean energy?

I have this idea about how to get clean energy ALL around the world and would like to know how possible it is to implement it. say that the matter of money and international relations are out of the question.

The idea is to put solar panels in many countries along the equator. There must be enough to meet the worlds electricity needs. The problem is that obviously the sun doesn't shine 24/ so the key is to make enough solar panels in a region to support power needs for the entire world. So now when it's night time in lets say china, it's daytime in the mexico or whatnot and it provides the power for the whole world. So basically at night the country you live in uses power from a country that is in daylight. During the day, your country/area provides power for the rest of the world in nighttime.

So what would make this idea possible/impossible not thinking about international relations or the cost? Basically, what are the engineering aspects that would make this feasible?
