[China Glass Network] In the past 2015, China's photovoltaic industry ushered in an explosive year, especially the installation of distributed photovoltaics is constantly emerging, the author is located in most cities in Shandong, photovoltaic installation companies from 3- Five families began to increase to more than a dozen, and emerged with increasing trends. As the market competition continues to intensify, some shoddy and scams are also taking the lead.
Below, the author has made some disclosures on several phenomena currently on the market, so as not to be fooled.
First, low-priced sales:
At present, in the photovoltaic installation market in the city, the price of individual installation companies has reached 6 yuan / watt, especially in the case of some owners who do not understand the situation continue to squeeze the price, the original price of more than 10 yuan / watt has been showing a downward trend. After I saw some low-cost PV installation projects on the spot, I had to feel that there was no good goods and it was our owners. The price of 6 yuan / watt, for many formal installation companies may not even cost enough, some black-hearted enterprises in order to make money, can only be shoddy. Components, brackets, inverters and even cables are all low-quality products. The promised components are not available for 25 years or even 5 years. Some components are less than 50% of normal power generation efficiency, and even lower. Short-sighted behavior, not only the owners, but also their own, and even the entire distributed photovoltaic installation industry.
In addition, it cannot be connected to the grid:
Many enterprises do not have the qualifications for photovoltaic installation and construction qualification. After the completion of the power station, they cannot connect to the grid. As a result, the owners can only choose to use their own products and affect their income. I have encountered similar things. A company has a low price in a county. Installed 5 households, after the installation is completed, they can't connect to the network, simply run the road directly, so that the owners want to cry without tears. Later, the owner finds a formal third-party enterprise, but the formal enterprises are also quite embarrassed because they are not the products they install, the products Quality is difficult to control, and they also find that the quality of the product does have problems (from the power generation can be found), in such cases, can only refuse to receive. Therefore, it is very important for many owners to choose a formal installation company when they sign the installation contract and standardize the installation.
Again, after-sales maintenance is not perfect:
At present, many PV installation companies are only responsible for the front section. I have installed it for you, and finished the network. Once I left, some enterprise phones are not answered. I have seen such a situation at the installation site of a company. It is a distributed photovoltaic power station installed in 2011. It has been close to 5 years. The power station is densely dusted, some of the brackets have been rusted, and power generation efficiency has also been problematic. Some accidentally damaged components cannot be replaced. The key is that the inverter is also a problem frequency. Out, according to the introduction of the person in charge of the company, the installation company received the money, and no longer seen the figure, even a daily maintenance manual did not stay. Such an installation company does make many owners sad and hurts the confidence of PV installation companies.
So, how to choose a quality installation company? Here we recommend that customers have three elements to consider:
First, we must look at the corporate image:
At present, there are still few brands in the photovoltaic installation industry (the service level of distributed power station installation companies established by some brand component companies is also lacking). For the owners of the region, the choice of enterprises mainly depends on the years of establishment, the installation cases and the overall Image perception, a company that focuses on its own image is a responsible enterprise in most cases.
Second, look at the business case:
Choosing a favorite installation company, it is recommended to go to his previous installation case, observe the field, understand the construction process, see the power generation situation and after-sales maintenance, and then chat with the owner, there will be a more intuitive understanding, and then make a judgment analysis .
Third, we must look at the qualifications of the enterprise:
This is very important. It is related to whether it can be smoothly connected to the grid. Does the company have a business license or a construction permit? Is it a person's guerrillas? These are directly related to the quality of your project and the integration and subsequent maintenance.
