SOLAR FOTOVOLTAICA Cómo proteger las instalaciones fotovoltaicas Las aplicaciones fotovoltaicas se han convertido en una fuente alternativa de energía eléctrica ampliamente utilizada hoy en día. Debido a sus necesidades específicas en comparación con otras aplicaciones más habituales nace una nueva generación de componentes eléctricos diseñados para trabajar con corriente continua que deben tenerse en cuenta como una parte fundamental de la instalación.
