All grid-tied solar panels (i.e. what you get when you install solar panels at your home) will do that automatically. Don't don't have to do anything. Solar will be consumed in priority. If there's too much it will be sold and if there's some missing il will be automatically (by the laws of physics) imported from the grid.
