The most important part of the power station is the most important part of the solar cell components, also known as photovoltaic panels, battery panels. Its quality is undoubtedly a direct impact on the efficiency of the system and the service life, layman how to distinguish between good and bad PV modules What?
There is a friend from childhood to live in the city, for the shuttle in the road in any car brand, dressed in a wide range of clothes trademark can be doubled, but when she went to the countryside, even can not tell the wheat and leeks, can not tell the donkey and horse In fact, this is a very normal thing, because the textbook inside the things are very abstract, mechanized memory and reality there is often a big contrast.
Now, solar photovoltaic power generation is not only in a wide range of urban applications, in the rural areas is not what is rare, with the farmers to build more and more power stations, power station quality problems have become the concern of many owners, while for photovoltaic power plant Of rural users, they are not clear about the quality of the equipment, not to mention the professional knowledge of photovoltaic systems.
A friend engaged in the photovoltaic industry for more than ten years, he told us in rural areas after the construction of photovoltaic power plant after the half of the joy, hi is to enjoy the benefits of environmental protection, worry about the power generation is not high, the problem is still constant! Anxious.
So how to make photovoltaic power plants away from the hidden dangers? What skills do we need people?
Today we are talking about the important components of photovoltaic power plant PV modules.
The most important part of the power station is the most important part of the solar cell components, also known as photovoltaic panels, battery panels. Its quality is undoubtedly a direct impact on the efficiency of the system and the service life, layman how to identify the good or bad What?
Need to have 'five look' skills
A look at business.
Look at the components of the suppliers to see if the industry is not the mainstream brand, is not the Ministry of Industry and Publicity of the access enterprises, as of the current total of five batches of 244. There is a saying 'tree under the good shade', large brand components warranty and aftermarket Service is guaranteed.
Second look at the welding process.
Look at the battery when the string welding there is no leakage welding, this can be seen directly through the appearance.
Three to see the quality of the back pressure.
There is no uneven situation, or bubbles, wrinkles, etc. To find bubbles and wrinkles is not difficult, in the sun can be seen.
Four look at the border quality.
Is not strictly rectangular, the error is not too big.
Five to see the conversion rate.
The conversion efficiency is 250%. The conversion efficiency of the 260W PV module is 16%; the conversion efficiency of the 265W PV module is 16.3%; the conversion efficiency of the 270W PV module is 16.6%; if the company advertises the PVP of the 60P PVP Rate of more than 20%, ha ha! Certainly fake yo!
to sum up
Components are an important part of the photovoltaic power plant, once the problem, the people spend money and sweat built photovoltaic power generation power generation can not be guaranteed, let alone income, so no matter in the city or rural areas, users have to learn self-identification components Bad, the first power station to the first pass.
