In recent years, the Solar panels have become a crucial differentiator in the construction market, gaining more and more prominence among engineers, architects and landscapers.
What was once seen only as a roofing technology, today it has evolved into a versatile solution that combines design, sustainability and economy, expanding its applications to various surfaces, such as facades and even walls. The analysis is Liciany Ribeiro, CEO of BayWa re in Brazil.
“The competitiveness of modules is not restricted to energy efficiency alone. Compared to traditional building materials, the values of the panels, when analyzed per square meter, are highly attractive”, He highlighted.
“Furthermore, the photovoltaic modules offer a benefit that few finishing materials can provide: an average warranty of 25 years of energy production. This means that, in addition to being resistant to climate variations, they deliver long-term results,” highlighted the executive.
New frontiers for solar
In her view, more modern architectural projects have incorporated solar panels as cladding in homes and industrial facilities, transforming the surfaces of facades and even vertical structures into energy sources.
“Although there is a slight loss in energy generation capacity due to lower solar incidence in these areas, the advantage is still clear: while other coatings only offer aesthetics, solar panels generate energy and reduce the carbon footprint of projects,” he emphasized.
Technology and design combined
According to Liciany, advances in design have been another important factor in the popularization of photovoltaic modules. Brands like Longi are innovating by launching models with a more harmonious design, such as the All Black, which uses matte black anodized aluminum and a discreet structure that resembles a switched-off LCD TV.
“For those looking for different aesthetic solutions, there are already options for colored panels, known as BIPVs, which offer even more versatility for integration with architecture,” he reported.
“This model can be integrated directly into the frame. In this case, it is essential to have individual energy management technology, because once applied to the architecture, we cannot control the external environment, such as, for example, the shade of a tree at a certain time of day, among other elements inherent to external environments,” she explained.
According to the CEO of BayWa re in Brazil, like any other coating, the modules also require maintenance, and access to them is something that should be foreseen in the project. “It is a joint effort with the architect, construction company and the window frame industry. This care is necessary to ensure the building is sealed.”
“The format allows the façade, balcony, brise-soleil and pergola to also become energy generators. This becomes a major differentiator for a public that is increasingly aware of its responsibility towards clean and sustainable energy in the long term, and most importantly, willing to value it and consequently pay more for it”, he concluded.
