Dear customer, I have never used this brand of solar energy. The one I have at home is from Royalstar, which is also wall-mounted. It's pretty good to use.
Wall-mounted solar water heater
Advantages: 1. Installation is not limited by the ground, as long as it can receive sunlight
< p> 2. It works under pressure and the water outlet pressure is enough (cold water pressure should be enough), you can supply water to more points3 .Put less cold water and the water inlet pipe distance is short
4. There is little external insulation, relatively speaking, you need to save a little cost of heating tape. electric
Disadvantages: 1. High price
2. Small volume, basically maintained at 80-100 liters (ordinary solar smallest is 160 liters-58*1800, only 16 )
3. The temperature is low, the maximum temperature will not exceed 75 ℃, and in winter, it ist basically kept at 30℃ - 40℃ without electric backup heating
4. Electricity cost, because the wall mounted solar panel does not heat in winter, it is completely requires electric assistance, so If you want to use hot water, you need to add electricity.
5. As it works under pressure, you need cold water and hot water before you can use it. use once. cold water pressure is low, the product cannot be used without cold water
