In my personal opinion, the ranking of the best quality solar water heaters:
Ranking criteria: We will not rank according to well-known brands, famous Chinese brands, exemption from inspection and other honors. For example: Well known now, you can have money. If you buy it, Well Known is the worst, and you can still win a case. For example: Tongji Sunshine is a small company, just like Sanle. . Can Sanle, a company that doesn't even produce vacuum tubes, guarantee quality? In short, ranking is now very common by company - technology, research, product materials, effectiveness, user reviews, etc. /p>
1. Tsinghua Sunshine Solar, a solar energy research institution, if there is no Tsinghua Sunshine, then there are other solar energy, China's No. 1 solar vacuum tube manufacturer and the first solar manufacturerthe material is very; good and efficiency is high. This is the only manufacturer that doesn't like to brag or hype. But if you like the price, you can set it aside and you will find it. Brand" (National Quality Inspection Bureau), China's only "most competitive brand" (Ministry of Commerce), many technical honors, too many to mention one by one. --- (Tube production empty, warranty)
2. Huangming/Yijianeng/Odike/Flit, (sometimes there are special discount machines, which are not included in the ranking, don't be fooled. Also : Fleet is a high-end product) these 4 brands belong to the same family The quality is about the same, the price is too high, the solar material is very good, the technology is average, and the production scale. is big, but I like to brag, hype and boast about famous Chinese brands and well-known brands.ues (vacuum tube production is guaranteed)
3. The material is very good, the hype is average, the company is large, the technology is above average, a famous Chinese brand (produces vacuum tubes, guaranteed)
4. Huayang has good materials (Note: Golden Years and Xingfuquan are not included in the ranking. In terms of commercial scale, there is little hype). . Famous Chinese brand, well-known brand (vacuum tube production, warranty)
5 Sun Rain/Four Seasons Muge, these two belong to the same family and we will not comment separately, but be careful. that currently Siji Muge is still produced (processed) in Taiyangyu, but the production base is being prepared to be put into production. The materials and technology are average, and they like to hype (also talking about high heat retention is also a lie..) In terms of scalee company, Taiyangyu is a famous brand in China and has a well-known brand, while Siji Muge only has a well-known brand and it comes from judicial certification (vacuum tube production is guaranteed)
6 , Brilliant; Medium materials, medium technology, likes to hype, medium to low enterprise scale, the first to have solar energy to exhaust There are famous Chinese brands and well-known brands, but they come! of judicial recognition (the vacuum tubes are not self-produced, half of them come from Linuo)
7 Sang Le; The materials are of average quality and the technology is not advanced. He likes to hype and brag. (Are you also talking about digitalization? That's really misleading people.) But the price is low, the company size is medium and the well-known brand comes from judicial recognition (vacuum tubes are notnot inferior), almost from Linuo)
Samp Solar is not within the scope of this review, because it is an engineering-based solar water heater company, very good quality and high technology, so it must be rated at least sunny before rain. Surface, close to Huayang,
Others: Yuansheng, Sangxia, Tongji Sunshine, Zilida, Tianpu, Xinyu, Sunbao, etc., the quality is slightly better than other brands, for various reasons The reasons cannot be classified.
First of all, let me state: I am not a staff member of any solar power company, but I am familiar with each solar power company, I have tested tens of thousands of solar panels and thousands. solar energy companies. The detection range includes backing material thickness, material, coating thickness, insulation thickness, foaming material, layerof vacuum tube membrane, vacuum degree, temperature efficiency, etc. I won't expose them one by one here, because this company The hotel network is not very good! That's all I have to say!
There are several reasons for energy consumption 1. It is. is linked to weather conditions. More energy is consumed on cloudy and rainy days. 2. This is related to water consumption. If water consumption is large and sunlight is insufficient, energy consumption will be large. 3. This is related to the heat collection efficiency of the solar vacuum tube and the vacuum degree. If the vacuum degree is small and the heat dissipation is fast, even if the hot water industry is exhausted, electric heating is still required, which consumes a lot of energy. .
