In a large clear container, combine the cold water, tea bags and fresh mint leaves. Cover and place in the sun - indoors or outdoors - for 2 to 5 hours or until the tea is as strongly flavoured as you like. Strain tea into a pitcher and add juice.
While the tea is steeping in the sun, make the simple syrup. In a small saucepan or a microwave-safe measuring cup, combine the sugar with - cup (125 mL) water. On the stove or in the microwave, bring just to a simmer, stirring until the sugar is completely dissolved. Cool slightly, then add to the tea gradually, tasting until it is sweetened to your taste - you may not use all the syrup
Chill and serve over ice.
