The first is to buy a famous brand.
In today's solar energy industry, the brand-name products from the quality to after-sales service, are guaranteed. And consumers have some difficulties to choose by their own observation and comparison. For example, the key components of the solar water heater is the insulation of the tank and the liner steel material and thickness, only after the destruction of the tank can energy out of the liner thickness and material. There is also the quality of the vacuum tube, these things even if we are in the industry, without destroying the product, without the use of precision instruments, can not identify the case.
But once the quality is not qualified damage, will not be able to repair. For example, if the tank liner leaks, you must find the leakage point, will be completely destroyed at one end of the tank end cap, digging out the insulation, welded with argon arc welding, and then re-foamed with polyurethane, and then look for a new end cap buckle. A toss down, the cost and buy a new tank to replace about the same, and the weld will not last long.
So, buy a brand name or much more worry, is more expensive.
So what is a name brand?
Solar water heater honor gold from high to low are "Chinese famous brand", "national inspection-free", "China's well-known trademark".
Give you a few recommendations of the real famous brand!
The General Administration of Quality Supervision, Inspection and Quarantine of China's famous brand products, the entire solar water heater industry is currently selected only eight companies, as follows:
Linuo Ruite Shandong Linuo Ruite New Energy Co.
Yi Jia Neng Shandong Yijia Neng Solar Energy Co.
Sunrise Oriental Sun Rain Lianyungang City, the sun and rain water heater Manufacturing Co.
Hua Yang Jiangsu Huayang Water Heater Co.
Huayang Jiangsu Huayang Solar Energy Co.
Huangming Shandong Huangming Solar Energy Group Co.
Sanle Digital Shandong Sangle Solar Energy Co.
Qinghua Sunshine Beijing Tsinghua Sunshine Solar Energy Equipment Co.
Huanghuang Jiangsu Huaiyin Huihuang Solar Energy Co.
The State General Administration of Quality Supervision, Inspection and Quarantine announced the national Inspection-free solar water heater products
1 Shandong Linuo Ruite New Energy Co. Linuo Ruite domestic vacuum tube solar water heater
2 Huangming Solar Group Co. p>4 Shandong Yijianeng Solar Energy Co. Yijianeng Series
5 Shandong Sangle Solar Energy Co. Sangle Digital Home
5 Jiangsu Sangxia Solar Energy Industry Co. Ltd. Sunrise Solar Rain TZBA,TZCS,TZCD
9 Jiangsu Huaiyin Huihuang Solar Energy Co. Huihuang Ordinary type, photoelectricity complementary type; electric auxiliary heating @
10 Jiangsu Huayang Solar Energy Co. Ltd. Qunsheng series
The quality of these products is not bad, your question is the price-performance ratio, which is the highest? This mainly depends on the local dealer's pricing, some require low profit, the price is cheap; some require high profit, the price is expensive. In this way I divided these products again into three, six, nine and so on, to give you a quality reference, you go and dealers bravely cut the price to go.
The best: Tsinghua Sunshine (in addition to the speed of music series), Huangming, Yijiaoneng.
General: Huayang, Qunsheng, Sang Le, brilliant, sun and rain, four seasons Shuge
Bad: Tianpu . Disclaimer: I am not an employee of any of the above companies, our company's products can also be, the price point is also cheaper than them, our retailers in your place do not know if there.
There is another way is to ask neighbors, relatives, co-workers are using what brand, if used for more than three years there is no problem can also be bought, regardless of whether it is a famous brand.
And a few suggestions for you:
1, don't listen to dealers and promoters, this three high, the thermal wall, are making gimmicks, in recent years, the solar water heater industry, there is no breakthrough technology.
2, vigilance to avoid buying counterfeit products.
Our industry as a result of production and technical threshold is relatively low, coupled with poor supervision, so the situation of mixed fish and dragons is more serious, the following I say a few means of black sheep in this industry:
1), the evening of colleges and universities. A few years ago, the rise of the Beijing brand and the phenomenon of colleges and universities, in fact, most of the relationship with colleges and universities are not at all. Registered trademarks similar to "Peking University" "Qingdao
Hua" such manufacturers, 99% is to play colleges and universities, that is, the trademark is not registered at all, the quality is good can only look at your luck. This, I know of only "Tsinghua
Sunshine" trademark for the registered trademark, but in this year's solar water heater industry summit, the second half of the "Tsinghua Sunshine" this trademark is also very likely not to be used.
2), evening appliances brand-name. In recent years, and the rise of the brand of electrical appliances to play the balloon wind, what "Haier Sunshine", "Gree Sunshine", "U.S. Sunshine", in fact, and people
large enterprises have nothing to do with, may be in their own homes in the yard, the two families plus seven aunts, eight aunts production.
3), the evening industry famous brand. "Hong Kong Huangming", "International Huangming" and other banners are counterfeit, they are generally playing the Hong Kong Huangming company, the trademark is not Huangming.
Additionally told you that the solar energy industry is the main digitalization of the solar energy industry that his surely good, there is another is also Xizi instrumentation is also okay, I do not know if you have to sell it
