Best Chinese solar panels 2022

There is always a prejudice with Chinese products, you always hear “it’s a bad product because it’s Chinese” “it’s Chinese, it’s a copy” “Chinese things are of low quality” and more things like this, but is this really true? China has a great development in the production of solar panels, many brands and different quality, here we will give you a panorarama of what is Best Chinese solar panels 2020.

In recent years Chinese manufactures have achieved a high quality due to government policies and large investments in machinery and advanced technology.

 

1)  CHINESE PANELS: VARIABLE QUALITY AND SOME WARRANTIES

While some of the best photovoltaic cells in the world come from China, and there are many good Chinese photovoltaic panels on the market, on the other hand there are hundreds of small Chinese companies that produce cheaper but lower quality cells. Chinese companies famous for their panels do not have more than 5, while the rest are unknown brands of more or less dubious quality.

 Therefore, with the photovoltaic panels and solar cells “made in China” there is always the question of quality. You know something about it, for example, a Pugliese photovoltaic park that installed low quality Chinese panels, which were composed of two metals with different expansion coefficients, so they bent under the southern heat and now must be discarded. In these cases, taking legal action against the Chinese company, even in the presence of a written guarantee, turns out to be a battle without hope: it is a blow against a real “rubber wall”, even if it has a multitude of lawyers.  

 

2) T  HIPOLOGIES OF PANEL MANUFACTURERS

We can distinguish four main types of producers of photovoltaic panels: (1) Chinese manufacturers “pure”: they are based in China and sell panels “made in China”, and for the most part are manufacturers of reliability, all the more dubious as smaller is the size; (2) Western producers, and therefore, in some cases even Italian, who sell panels produced substantially in China, but which are assembled and “renamed” in the final country; (3) “pure” Western producers, who from China buy most of the raw materials or a little more: unlike the previous ones, they generally produce panels of excellent quality; (4) the Chinese-Western multinationals, 

Por lo tanto, es mejor centrarse en los paneles.Los occidentales “puros” si buscan una calidad excelente (pero paguen con un precio más alto), y para los de las grandes empresas chinas y / o multinacionales por un buen compromiso entre precio y calidad.

3) ¿CUÁLES SON LOS PRINCIPALES PRODUCTORES DE PANELES? 

El primer productor mundial de paneles fotovoltaicos (en términos de capacidad de producción) es American First Solar, con aproximadamente 1,1 GW producidos por año, seguido de Suntech.(0.7 GW), una empresa con sede en China cerca de Shanghai, en el “Valle Solar” chino. Los paneles Suntech en Italia son conocidos por su buen precio, pero “barato”, en el caso de esta empresa china, no significa mala calidad: por el contrario, es uno de los 5 mejores fabricantes de paneles solares del mundo en términos de calidad. y sus paneles se utilizan en todas partes, desde Alemania hasta los Estados Unidos.

 Continuando en el ranking de los principales productores mundiales actuales (los 10 principales proporcionan hasta el 45% de la producción mundial) encontramos Sharp, Q-Cells, Yingli, JA Solar, Kyocera, Trina Solar, SunPower y Gintech. Algunas de estas son empresas chinas: de hecho, los 5 principales productores más importantes de China son Suntech, Yingli, JA Solar, Trina Solar, Solar Canadiense. También en Europa hay numerosas empresas grandes: SolarWorld, Solon, Aleo, Schott, RecSolar, etc.

Tabla. Los 10 mayores productores mundiales de paneles fotovoltaicos.

 

Nombre de la empresa país Producción anual (en MW)
Primer solar Estados Unidos 1100
Suntech China 704
afilado Japón 595
Q-Cells Alemania 586
Yingli China 525
JA Solar China 520
Kyocera Japón 400
Trina solar China 399
SunPower Estados Unidos 397
Gintech Taiwan 368

4) LAS CERTIFICACIONES NECESARIAS

Paneles fotovoltaicos, si se utilizan en un sistema fotovoltaico conectado a la red de la Unión Europea, mucho más si desea acceder a los incentivos de la cuenta de energía- Basta con que tengan el marcado CE y estén certificados de acuerdo con el reglamento específico (CEI EN 61215 para módulos de silicio cristalino, CEI EN 61646 para módulos de película delgada, etc.), que determina sus características eléctricas, térmicas y mecánicas. 

Si un producto tiene la certificación “TUV” (tenga en cuenta que TUV no es una certificación, sino un organismo de certificación grande, que tiene una lista de paneles certificados en su sitio), ciertamente cumple con la legislación mencionada anteriormente. Entre las pruebas más importantes que deben pasar los paneles para obtenerla: la que determina la potencia (en W p) bajo condiciones de insolación estándar, controles en condiciones de temperatura extrema y pruebas de resistencia mecánica. Las pruebas de prueba y verificación deben ser realizadas por laboratorios acreditados por EAA ( Acuerdo de acreditación europeo ) o que tengan acuerdos de reconocimiento mutuo con EAA.

5) DURACION  DE LOS PANELES Y GARANTÍA

Los paneles fotovoltaicos de hoy (mono y policristalino, película delgada) tienen una duración estimada de aproximadamente 80 años, aunque es plausible suponer que se están abandonando mucho antes tanto por la mejora tecnológica ofrecida por los nuevos productos como porque, debido a la fatiga del Los materiales, tienen una caída de rendimiento de hasta el 1% anual. 

The best photovoltaic panels on the market have a  real drop  in performance, which is determined with laboratory measurements, only 10% after 20 years and 20% after 40 years, which is a very satisfactory result. To guarantee the buyer, the current legislation requires a guarantee. in silicone panels with a minimum of 2 years for manufacturing defects and a minimum of 20 years to reduce performance over time. Nowadays, for most panels, the guarantee (reported by the manufacturers in the information brochures together with the obtained certifications and the various technical specifications) is 90% of the nominal yield after 10 years and 80% after 20 years.
