The disadvantage of solar energy is that it is easily affected by weather and extreme weather. Some high-rise buildings above the space will have some problems, and the property may not be allowed to use solar energy for safety reasons. Now there is a kind of balcony wall-mounted solar energy, which can put the collector on the balcony, but it looks abrupt and affects the appearance. In terms of weather, if the weather continues to be cold and there is not enough solar support, it is difficult to maintain the hot water demand of the family.
If you choose black, porcelain, old and human solar energy, this problem will not appear. It belongs to ceramic solar energy, and the heat absorbing coating is not afraid of air drying and has the same life as the building. Don't worry about freezing pipes in winter and exploding pipes in summer. Compared with traditional solar energy, it is safer and more worry-free.
