Advantages: 1. Installation is not limited by the ground, as long as it can receive sunlight
2. Pressure operation, the water outlet pressure is. sufficient (cold water pressure must be sufficient), more water can be supplied
3. Put less cold water and the water inlet pipe distance is short
4. Less external insulation, relatively speaking, it is necessary to save a little on the use of electric heating tape
Disadvantages: 1. High price
< /p>2. The volume is small, basically maintained at 80-100 liters (the smallest with ordinary solar power is 160 liters - 58*1800, only 16) 3. The temperature is low, the maximum temperature will not exceed 75°C and in winter, it is basically maintained at 80-100 liters without auxiliary electric heating 30℃ - 40℃ 4. It consumes electricity, because of the wall. -The solar panelmounted does not heat in winter and requires electrical assistance, so if you want to use hot water, you need to add electricity.
5. Because it runs under. pressure, it requires cold water and hot water before it can be used. Once the cold water pressure is low and there is no cold water, it cannot be used.
Is there solar water. heater installed on the balcony?
The water storage tank is a vertical cylinder with a cold water pipe at the bottom and a hot water pipe at the top. Balcony wall-mounted solar power, called balcony solar power, is a new type of solar water heater invented by Beijing Solar Energy Research Institute (Samp Solar Energy) and first launched in 2004 .The method of wall-mounted solar energy on balcony The separation of cold and hot water pipes is that the water storage tank is vertical.The barrel has a cold water pipe in the lower part and a hot water pipe in the upper part.
Yes, solar energy can usually be installed on the balcony. However, the direction of the balcony facing the sun must correspond to the south direction. The opposite side of the balcony should be at least 50 meters away. straight line and there should be no buildings higher than the height of your house. Block direct sunlight, otherwise any solar energy not only on the balcony but also installed on the roof will be useless. Theoretical altitude and elevation values should be estimated based on your local dimensional values... There are many solar elevation angles available in Baidu.
