In my personal opinion, the ranking of solar water heaters with the best quality:

Ranking criteria: We will not rank based on well-known trademarks, Chinese famous brands, exemption from inspection, and other honors, such as: Well-known Now If you have money, you can buy it. Well-known is the most rubbish, and you can get it if you file a lawsuit. For example, Tongji Sunshine is a small business, and so is Sanle. Can a company like Sanle that doesn’t even produce vacuum tubes guarantee quality? In short, Well-known is now Very common. This ranking is based on companies - technology, research, product materials, efficiency, user reviews, etc.

1. Tsinghua Sunshine Solar, a solar energy research institution, if there is no Tsinghua Sunshine, then there are other solar Oh, China’s first solar vacuum tube manufacturer is also the first solar manufacturer; the material is very good and the efficiency is high. It is the only manufacturer that doesn’t like to boast or hype. But the price is too high. If you like the price, you can put it aside. There are "China Famous Brands" (National Quality Inspection Bureau), China's only "most competitive brand" (Ministry of Commerce), and many technical honors. --- (Production of vacuum tubes, guaranteed)

2. Huangming/Yijianeng/Odik/Flit, (sometimes there will be special price machines, which are not included in the rankings, please don’t be fooled. Also: Fleet is a high-end product) these 4 brands They are from the same company, the quality is about the same, the price is too high, the solar materials are very good, the technology is average, and the production scale is large, but they like to brag, hype, and brag. Some of their products are Chinese famous brands and well-known trademarks (the production of vacuum tubes, etc.) Guaranteed)

3. Linorite. The material is very good, the hype is average, the company is large, the technology is average, and it is a famous Chinese brand (produces vacuum tubes, guaranteed)

4. Hua The materials are good, (Note: Golden Age, and Xingfuquan series are not included in the ranking), the scale of the company, there is little hype, Chinese famous brand, well-known trademark (production of vacuum tubes, guaranteed)

5 Taiyangyu/Four Seasons Muge, these two belong to the same family and I won’t comment on them separately, but please note 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. I like it. Hype, (it is also a lie to say that it has strong heat retention). In terms of corporate scale, Taiyangyu is a famous brand in China and has a well-known trademark, while Siji Muge only has a well-known trademark and it comes from judicial certification (it produces vacuum tubes and is guaranteed)

6. Brilliant; the materials are average, the technology is average, and I like to speculate. The company is of medium-to-low scale. It is the first to have vented solar energy! There are Chinese famous brands and well-known trademarks, but they come from judicial recognition (the vacuum tubes are not self-produced, half of them are from Li No)

7 Sang Le; materials are of average quality, no technology, likes to hype, likes to brag, (also talking about digitalization? It really fools people) but the price is low, the scale of the company is average, and the well-known trademark comes from judicial recognition (Vacuum tubes are not a subsidiary product, they almost come from Linuo)

Samp Solar is not within the scope of this review, because this is an engineering-based solar water heater company with very good quality and high technology, so it must be ranked at least Also ranked in front of Taiyangyu, close to Huayang,

Others: Yuansheng, Sangxia, Tongji Sunshine, Zilida, Tianpu, Xinyu, Sunbao, etc., the quality is better than other brands Slightly better, but cannot be ranked due to various reasons.

First of all, let me declare: I am not a staff member of a solar energy production company, but I know every solar energy company well. I should have tested tens of thousands of solar panels. There are thousands of solar energy companies. The testing scope includes the thickness of the bracket material, the material, the thickness of the liner, the thickness of the insulation, the foaming material, the film layer of the vacuum tube, the degree of vacuum, the thermal efficiency, etc. I don’t agree here. As soon as it was exposed, because the network in this hotel was not very good! That’s all I have to say!
