Idle fish to buy those components buyers want to cry 'pit' you must be careful!

In addition, if buy second-hand components, so even a manufacturer brand product, the user's interests is difficult to secure. The article content is for reference only. In the production of photovoltaic modules has certain defect rate, according to the normal process, the defective component shall be sold to recycling plant, by recycling plant after extraction of available raw materials, processing again turned to manufacturing. Photovoltaic industry prices more transparent, a line of plate heat exchanger manufacturers product prices, to a very low price to buy the components and equipment, its quality, such as cracking, solar photovoltaic glass leakage phenomenon is not surprising. The harm of inferior component is not confined to the naked eye is see these phenomena. Inferior component efficiency down very quickly, if there is quality assurance products to ensure 90% in the first ten years of using the power generation efficiency, so efficiency is inferior components may use only three to five years will fall to 50% & ndash; 60%. 'Photovoltaic (pv) of the world' this is a comprehensive system to introduce the development of photovoltaic (pv) in the past, present and future the sum of the corpus, wide-ranging, can meet the needs of different readers. Solar photovoltaic (pv) network statement: this information is reproduced from the media or other Internet web site, network cooperation photovoltaic network published the article for the purpose of the information, does not mean that agree with his point of view or confirm its description. Finally, on the blackboard, when we buy photovoltaic modules, avoid by all means is covet cheap, want to buy from formal channels, to ensure that each other is a sales. It is understood that the pv modules user buy in idle fish.

you can see in the video, the surface of the component and wiring all appeared charred traces, and the surface is a visible cracks. Which cannot be found in the early years of the users in the use. This paper not only includes editor Wolfgang & middot; Dr Parr, himself in his new energy career, more than 50 years of photovoltaic power station operation center to the deep understanding of the development of photovoltaic (pv) and the system summary, also include the global photovoltaic industry professionals engaged in new energy or review, at the same time, the development of photovoltaic (pv) difficult purchase after carefully check the component appearance again after use. First, ground power station manufacturer promised 25 years warranty to promise, second, because of the photovoltaic modules power attenuation, every year there are certain its current capacity need according to the component before the power of the year to subtract, however the buyer is hard to judge whether the purchase of second-hand components have experienced extreme weather, violence, remove extra effects, such as second-hand component current power effectiveness is difficult to accurately measure. Specific attention to the following aspects: whether the cell spacing is uniform, arranging and tidy, with no open welding, welding and other welding, welding surface for the oxidation ( Oxidation of welding with yellow) Whether there is a bubble, the component of seal or delaminating phenomenon, photovoltaic panels open video software frame whether smooth, clean and tidy, no foreign body, no corrosion, etc. For idle fish private nature of the trading platform, open video software small make up to speculate that the seller is likely to do not have photovoltaic components sales professional qualification, and through the low price to gain consumer attention. Photovoltaic power station operation center to avoid buying second-hand remove components, want to choose a line of the overall system, ensure the quality and after-sale!

in this small make up remind everyone, only A grade components can circulate on the market, if you claim that it has low class B and class C components, so there is no doubt that he sold must be defective components. Due to defective components is absolutely forbidden to market, so some private trading platform has become the pusher of the hub. Covet is cheap to buy bad components, the ground station delay revenue losses small property, if the quality problem for photovoltaic power station fire, endangering the personal safety can be thed loss outweights the gain. In this process, some unscrupulous traders will intervene, through various channels to higher than recycling plant to buy these defective components, convex lens condenser heat resell price to sell. Solar photovoltaic (pv) net news: recently, a user on the network video released its photovoltaic cell components burned. Convex lens condenser heat
