Abstract

Assembly system for photovoltaic modular panels on flat roofs that includes, at least, one photovoltaic modular panel (M), at least one support structure (1); and at least one support structure (2) that holds it in an inclined position with respect to the support structure (1) and to the flat roof itself. The support structure (1) is ballasted; so that the photovoltaic modular panel (M) is supported on the flat roof and fixed to it thanks to the weight of the assembly. The ballast or weight of the support structure (1) is variable depending on the dimensions and/or weight of the photovoltaic module (M) itself carried. The inclination of the photovoltaic modular panel (M) with respect to the flat roof is determined by the configuration of the supporting structure (2).

Sistema de montaje de módulos fotovoltaicos en cubiertas planasMounting system for photovoltaic modules on flat roofs

Objeto de la invenciónObject of the invention

El objeto del invento se refiere a un sistema de montaje de módulos fotovoltaicos en cubiertas planas.The object of the invention refers to a mounting system for photovoltaic modules on flat roofs.

Antecedentes de la invenciónBackground of the invention

En el actual estado de la técnica se conocen sistemas de montaje de módulos fotovoltaicos en cubiertas inclinadas, que son profusamente utilizados estando por ello bastante desarrollados y optimizados.In the current state of the art, mounting systems for photovoltaic modules on sloping roofs are known, which are widely used and are therefore highly developed and optimized.

También se conocen sistemas de montaje de módulos fotovoltaicos en cubiertas planas, pudiendo citarse, por ejemplo y entre otros, los documentos WO2011045185, DE102014102746, DE102011120362, DE102010013369, DE102008052600 y ES1070511.Systems for mounting photovoltaic modules on flat roofs are also known, mentioning, for example and among others, the documents WO2011045185, DE102014102746, DE102011120362, DE102010013369, DE102008052600 and ES1070511.

Problema técnico a resolvertechnical problem to solve

La instalación de módulos fotovoltaicos requiere una disposición inclinada de éstos para obtener un mayor rendimiento. En cubiertas inclinadas suele aprovecharse la propia inclinación de la cubierta pero en cubiertas planas el módulo fotovoltaico queda horizontal (ver, por ejemplo, el documento ES1070511) y su rendimiento disminuye muy notablemente.The installation of photovoltaic modules requires an inclined arrangement of these to obtain a higher performance. On sloping roofs, the roof's own inclination is usually used, but on flat roofs the photovoltaic module remains horizontal (see, for example, document ES1070511) and its performance decreases significantly.

Las soluciones que se conocen hasta ahora para montar módulos fotovoltaicos en cubiertas planas y dejarlos inclinados son complejas porque:The solutions that are known up to now to mount photovoltaic modules on flat roofs and leave them inclined are complex because:

• emplean numerosos componentes materiales y requieren mucha mano de obra "in situ” para montarlos (ver, por ejemplo, el documento DE102014102746);• they use numerous material components and require a lot of labor "on site" to assemble them (see, for example, document DE102014102746);

• emplean materiales (por ejemplo, adhesivos en el documento ES1070511) que pueden afectar negativamente a la cubierta original;• use materials (for example, adhesives in document ES1070511) that may adversely affect the original cover;

• requieren componentes prefabricados muy voluminosos (por ejemplo marcos portapaneles y bloques de hormigón en el documento DE102011120362) que son difíciles de manejar y complicados de transportar hasta la cubierta de un edificio. • require very bulky prefabricated components (for example panel frames and concrete blocks in DE102011120362) that are difficult to handle and difficult to transport to the roof of a building.
