Frameless solar panels
In order to talk clearly about what frameless solar panels are, we must first start with bifacial solar panels.
As their name suggests, bifacial solar panels are panels that work on both sides. That is to say, they capture the sun’s radiation, both on their front and back sides, although obviously, the intensity with which they capture sunlight on their back side is not the same as the first side, which receives the impact of the sun’s rays directly. You can read more about bifacial solar panels here.
Frameless solar panels are actually frameless bifacial solar panels. They are part of an innovative technology that aims to increase the efficiency of the panels.
They are photovoltaic modules composed of They are photovoltaic modules composed of polycrystalline silicon cells, with high efficiency and anti-reflection treatment.
These panels are generally designed for self-consumption installations due to their easy installation, as they do not require the assembly of structures, which, among other things, reduces the weight that we add to the roof of our houses.
In addition, these panels have lower degradation rates, which considerably increases their useful life, almost 25% higher than that of traditional framed modules, and provide higher efficiency ratios by encouraging the use of bifacial solar panels, both for roof and ground.
Of course, these solar panels also have their disadvantages – they are much less economical than regular solar panels, as only a few manufacturers offer them, and they are much less robust. They have to be treated with extreme care, they require more maintenance of the plant and they have to have a 3H monopole structure configuration which optimises the bifacial behaviour of the module and produces less shading.
