RESUMEN: La instalación de energía solar fotovoltaica en edificios plurifamiliares existentes, ya sea en instalaciones de autoconsumo compartido o individual se enfrenta a barreras legales, técnicas y de gestión de las decisiones en comunidades de propietarios. En base a la experiencia de una instalación realizada para uso individual en un edificio en el año 2018, el artículo analiza con detalle las principales barreras y propone acciones que permitan impulsar instalaciones en comunidades de propietarios. La monitorización detallada durante el primer año de operación ha permitido conocer que el nivel de autoconsumo es del 36% y que la instalación podría amortizarse hasta en 9 años. El proceso descrito se enmarca en una iniciativa de compra colectiva de instalaciones solares fotovoltaicas “llave en mano” que reduce las barreras al desconocimiento técnico que pudieran tener los ciudadanos. Si como sociedad queremos que las cubiertas de los bloques de viviendas puedan contribuir a la mitigación del cambio climático, es necesaria una labor de concienciación que minimice las barreras de gestión en las comunidades de propietarios.
ABSTRACT: The installation of solar photovoltaic systems in existing multifamily buildings, for individual or shared generation, face a set of barriers going from legal and technical aspects to the ones related with how decisions are taken in these buildings between dwelling’s owners. Based on a real experience of one photovoltaic system for individual use in a multifamily building in 2018, the current paper analyzes the main barriers and proposes actions to push photovoltaics in multifamily buildings. The detailed monitoring of the installation in the first operative year shows that the supply cover factor is 36% and the investment could be recovered within up to 9 years. The process was done in the framework of a collective initiative to launch up top 100 turnkey photovoltaic systems showing how this contributed to reduce technical unknowns of the citizens. If the society wants that photovoltaics in multifamily buildings contribute to mitigate climate change, an awareness work is necessary to minimize the barriers that community of owners can pose to individual proposals.
