In the heart of Lithuania, researchers are harnessing the power of the sun to revolutionize building design and energy efficiency. Loreta Kelpšienė, a dedicated researcher from Šiaulių valstybinė kolegija, has been delving into the optimal use of solar modules in hotel building projects, with findings that could significantly impact the energy sector.
Kelpšienė’s study, published in the journal ‘Taikomieji Moksliniai Tyrimai’ (Applied Scientific Research), explores how the orientation and design of a building can maximize the efficiency of solar panels installed on its roof. By using PVsyst software, a universal tool for designing, analyzing, and optimizing solar power plants, Kelpšienė modeled various building orientations and roof structures to determine the most effective setup.
The research reveals that the optimal position for solar modules is a roof slope facing southwest, with a rotation angle of 39° clockwise from the south. This orientation generates an impressive 19,166 kWh of energy per year. Even when accounting for potential tree shadows, the output remains robust at 19,029 kWh/year, a mere 0.7% difference. Compared to the traditionally efficient southern direction, the southwest orientation shows only a 3% reduction in energy output.
“This study highlights the importance of strategic building design in maximizing solar energy potential,” Kelpšienė explains. “By carefully considering the orientation and roof structure, we can significantly enhance the efficiency of solar modules, making renewable energy more accessible and cost-effective.”
The implications of this research are far-reaching for the energy sector. As the demand for sustainable and renewable energy sources continues to grow, optimizing the use of solar modules in building design can play a crucial role in meeting these demands. Hotels, in particular, stand to benefit greatly from this approach, as they often have large roof spaces that can be utilized for solar panel installation.
Moreover, the findings suggest that future building projects should prioritize solar module efficiency from the initial design stages. By doing so, developers can ensure that their buildings are not only environmentally friendly but also economically viable in the long run.
Kelpšienė’s work is a testament to the power of innovative research in driving sustainable development. As the energy sector continues to evolve, studies like these will be instrumental in shaping a future where renewable energy is not just an option, but a standard.
The research, published in the journal ‘Taikomieji Moksliniai Tyrimai’ (Applied Scientific Research), underscores the potential of strategic building design in the renewable energy landscape. As we move towards a more sustainable future, such insights will be invaluable in optimizing energy use and reducing our carbon footprint.
