Why not use solar water heaters in the South
1: every night must be gathered together to take a bath, because it is not the top, each pipe before the hot water to release a lot of cold water2: the average annual cloud thickness, humidity, rainfall throughout the year. After the clouds cover the remaining amount of sunshine is less; rainfall days will be almost no light. Rainy weather is even more bitter, although it can be heated, but basically finished two people is cold water.
Because the weather is warmer in the South than in the north, there is not enough space for people to live in the south, there is a little floor of the south of the water supply is not convenient, etc.
3: get up in the morning brush your teeth and wash your face, but also to burn hot water, ah, you will be in order to wash your face with hot water......4: as well as the winter of the day to wash a hand or how much cold water with their own... Save electricity is not enough to take the water every day to go.
High floor buildings, the roof of the installation of solar energy supply within 4 layers may be good, then the high winter release hot water is difficult,
