What can be done to switch from solar power grid to electric power grid?

I know that it is quite possible to make switch that switches from solar powered grid to electric power grid energy. But I don’t know how to do it. But I would really like to know from the people who are expert in this field whether it is possible to do this kind of switching or not? If yes, then what can be done to make switch which switches from solar power grid to electric power grid? I would prefer such switch which is external for safety of my grid system. Any advice pertaining to my query would be highly appreciated. I hope to hear soon from your side. Thanks.
