There are four people in my family. What size solar water heater is suitable for me? What brand is good? how much is it? thank you

I am in the solar energy industry, and four people mainly look at the water consumption of your home. For example, a person uses 40L hot water every day on average, so it is best to buy 200L hot water, generally 20%-30% more, because the solar energy is different every day. If the solar energy is equipped with an instrument that can see the weather (such as the one with 10 1 digital water level display), then in the weather with less light,

As for brands, solar energy such as vacuum tubes, water tanks and brackets now has little technical content, and there is not much difference in quality between brands except for the functional differences of smart meters. So, if you don't know, I suggest you choose brands (such as Linuoruite, Four Seasons Muge, Sun Rain, Sangxia, Sang Le, Pu Tian, Huang Ming, Huayang, etc.). ) and then compare the prices. The price of a brand is several hundred yuan higher than that of a miscellaneous brand, but the quality is relatively guaranteed. However, these enterprises generally do not produce their own control instruments, which are all produced by OEM outside. Merchants often consider price competition factors, and most of them are equipped with simple instrument products, which have low utilization rate of hot water and poor safety. If you can find an installer, you can buy solar energy and install the instrument yourself. This is relatively more economical.

The difference between solar energy can be understood through a video. /v_show/id_XMzUwMTIyOTAw.html
