Recientemente, la Oficina Federal Suiza de Energ\u00eda invit\u00f3 a dos cient\u00edficos del Instituto Federal Suizo de Tecnolog\u00eda de Lausana y a su equipo de investigaci\u00f3n para estudiar la central el\u00e9ctrica, \u00a1y los resultados demostraron que su funcionamiento es bueno!<\/strong><\/p>\n\n\n\n

<\/strong>1. Una antigua central el\u00e9ctrica con una vida \u00fatil de 40 a\u00f1os<\/strong><\/strong><\/p>\n\n\n\n

Aunque el dise\u00f1o el\u00e9ctrico del sistema de la central el\u00e9ctrica TISO-10 ha sufrido varios cambios, a excepci\u00f3n de unos pocos inversor<\/u><\/a> reemplazos, todos los componentes han sido utilizados hasta el final, siempre expuestos a la intemperie y a la luz solar, y no han sufrido renovaci\u00f3n o modificaci\u00f3n., son muy pocos los m\u00f3dulos con cajas de conexiones y diodos de bypass reemplazados.<\/p>\n\n\n\n

\u201cLa resistencia mec\u00e1nica de estos componentes es asombrosa\u201d, subrayan los dos cient\u00edficos, acerc\u00e1ndose m\u00e1s a lo que hoy definimos como componentes de doble vidrio.<\/p>\n\n\n\n

2. 40 a\u00f1os de cambio<\/strong><\/strong><\/p>\n\n\n\n

El rendimiento de los componentes de las plantas TISO-10 var\u00eda significativamente. Los investigadores dividieron los paneles en tres grupos: los m\u00f3dulos con mejor rendimiento mostraron poco amarilleamiento, mientras que los otros dos grupos mostraron un amarilleamiento de moderado a alto.<\/strong><\/p>\n\n\n\n

Los materiales de encapsulaci\u00f3n de los tres grupos de paneles est\u00e1n fabricados con PVB, pero con distintos aditivos, lo que da lugar a distintas propiedades. \u201cLos detalles son decisivos. En este caso, cambiar un solo aditivo en el material de encapsulaci\u00f3n puede afectar al rendimiento de toda la planta fotovoltaica. Esto demuestra que la elecci\u00f3n del material de encapsulaci\u00f3n es fundamental\u201d, explicaron los investigadores.<\/p>\n\n\n\n

Adem\u00e1s, la inversor<\/u><\/a> Ha sido reemplazado cinco veces en 40 a\u00f1os.
3. Atenuaci\u00f3n de potencia<\/strong><\/strong><\/p>\n\n\n\n

Aproximadamente 21,5% de los m\u00f3dulos muestran una descomposici\u00f3n anual de -0,2%, lo que tambi\u00e9n coincide con los datos prometidos por el fabricante. Los cient\u00edficos afirman que la mayor\u00eda de los componentes han funcionado bien y han cumplido las expectativas iniciales. Es decir, al menos 70% de los componentes de esta central el\u00e9ctrica cumplen la vida \u00fatil de 35 a\u00f1os.<\/strong><\/strong><\/p>\n\n\n\n

Los investigadores destacan que la primera y m\u00e1s importante lecci\u00f3n que se desprende de la instalaci\u00f3n de plantas fotovoltaicas y de la investigaci\u00f3n de m\u00f3dulos es que la lista de materiales (BOM) es fundamental. La elecci\u00f3n del material es tan importante hoy como lo era hace cuarenta a\u00f1os.<\/strong>
<\/strong>4. El m\u00e1s antiguo <\/strong>central el\u00e9ctrica<\/strong><\/u><\/strong><\/a> En China todav\u00eda est\u00e1 en funcionamiento estable.<\/strong><\/strong><\/p>\n\n\n\n

En Gansu, China, tambi\u00e9n hay una antigua central el\u00e9ctrica construida en 1983. Tiene una historia de 38 a\u00f1os hasta ahora. Aunque los 10 kW de entonces se han reducido a 7 kW, \u00a1sigue generando energ\u00eda estable!<\/strong><\/p>\n\n\n\n
