Who can help me distinguish the quality of solar energy?

Teach you several ways to choose solar energy.

The first is to buy famous brands.

In today's solar energy industry, brand-name products are guaranteed from quality to after-sales service. However, if consumers want to choose through their own observation and comparison, it will be difficult. For example, the key components of a solar water heater are the insulation layer of the water tank and the material and thickness of steel in the water tank. The thickness and material of the water tank can only be determined after the water tank is destroyed. There is also the quality of vacuum tubes, which does not destroy products and does not use precision instruments. Even people in our industry cannot identify them.

But once the quality is unqualified and damaged, it will not be repaired. For example, if the water tank liner leaks, it is necessary to find the leakage point, completely destroy the end cover at one end of the water tank, dig out the insulation layer, weld it with argon arc welding, re-foam it with polyurethane, and then find a new end cover to buckle it. After a toss-up, the cost is similar to buying a new water tank and changing it, and the welding place will not take long.

So it's much easier to buy famous brands, but the price is more expensive.

So what is a famous brand?

From high to low, the honorary gold content of solar water heater is "China Famous Trademark", "National Inspection Exemption" and "China Famous Trademark".

The quality of these products is not bad. Your question is cost-effective, which is the highest? This mainly depends on the pricing of local dealers, and some require low profits and cheap prices; Some require high profits and high prices. In this way, I will divide these products into three grades, six grades and nine grades to give you a quality reference. You can bravely bargain with the dealer.

Best: Tsinghua Sunshine (except Happy Series), Huang Ming, Linoret, Billion Canon, Pu Tian.

General: Sun Rain (Four Seasons Mu Ge), Huayang, Brilliant,

Poor: Sang Le.

Disclaimer: I am not an employee of any of the above companies. Our products are ok, and the price is cheaper than theirs. We don't know if our retailers have it.

Another way is to ask neighbors, relatives and colleagues what brand they use. If you have used it for more than three years, you can buy it whether it is a famous brand or not (under the condition of ensuring after-sales service).

Here are some suggestions for you:

1, don't listen to the bluff of dealers and promoters, this "three highs" and that "insulation wall" are all gimmicks. In recent years, there is no breakthrough technology in solar water heater industry. The same is true of the digitalization of Sang Le, which is actually a solar water temperature and water level gauge. In fact, the failure rate of the water level meter with Chinese characters may be lower. Also, a friend of mine in Jinan only used Sang Le's solar energy for three years. Just after the warranty period, the water tank leaks, and the manufacturer is not responsible for finding it.

2. Be vigilant and avoid buying counterfeit products.

Due to the low threshold of production technology and poor supervision, the situation of mixed fish and dragons in our industry is more serious. Let me talk about the black sheep in this industry:

1), near the university. In fact, the phenomenon of playing the Beijing card in the past few years has nothing to do with colleges and universities in Otawa. The registered trademark is similar to "Peking University" and "Qing"

99% of manufacturers like China are playing the edge ball of colleges and universities, that is, the trademark is not registered at all, and the quality can only depend on your luck. Among them, I only know "Tsinghua"

The trademark "Sunshine" is a registered trademark, but at this year's solar water heater industry summit, the trademark "Tsinghua Sunshine" will probably not be used again in the second half of this year.

2), next to the electrical brand. In recent years, electrical brands have a tendency to play the edge ball. What are "Haier Sunshine", "Gree Sunshine" and "Beautiful Sunshine" actually has nothing to do with other big enterprises. It may be that the couple and seven aunts gave birth in their own yard.

3), alongside the industry famous brand. Banners such as "Hongkong Huang Ming" and "International Huang Ming" are fake. They are usually produced under the name of Hongkong Huang Ming Company, but the trademark is not Huang Ming.
