It is reported that, including the middle and lower reaches of the industrial chain, there are about 3,000 companies related to solar water heaters, and at least 2,000 companies are manufacturing solar water heaters, but solar water heaters are a low-threshold industry and small workshop-style production. Traders are relatively more prosperous, coupled with the lack of industry standards, and the overall situation is uneven.
The new standard for domestic solar water heaters will be divided into three levels of energy efficiency, of which the first level products represent the highest energy efficiency, while the third level is the market access threshold, it is still a certain difference between the mandatory standards and the international standards. The standard is currently in the publicity stage and is expected to be officially implemented around the National Day. The matching energy efficiency label is expected to be announced at the end of the year.
