The scientists presented their findings in “ Control of PV integrated shading devices in buildings: A review,” which was recently published in Building and Environment. ![]() She estimates that it would be possible to see some instances of PV panels operating on the kinetic shading devices in 10 to 15 years. Every market, whether niche or not, would eventually reach the maturity, by definition,” she said. “Simple and less expensive solutions offered by the competitive market players will be beneficial for this niche market to reach some size. Kirimtat said the commercial viability of PVSDs may be accelerated by the green energy policies ruled by the governments. “ However, for each PVSD design, the optimal control method could change based on the climatic characteristics, building type, and orientation.” “To shorten the payback time of the PVSD systems, relevant control methods should be encouraged to be used in the early design process of these systems,” they said. The scientists stressed the importance of considering long-term performance monitoring of PVSDs as a crucial aspect for their viability, as well as the issue of replacing the shades. It was based on PVSD type, control strategy, and building type, with 77 business cases identified and briefly introduced. The scientists presented a detailed literature matrix to provide an overview of previous studies on different methods for PVSDs in buildings. Other techniques involve reinforcement of learning control and multi-agent control, while hybrid methodologies are based on all of these approaches. Soft control methods utilize mathematical models to predict system behavior analytically. Hard control techniques use dynamic systems such as energy and daylight simulation models in order to evaluate the thermal behavior of the buildings. The control strategies used to optimize the performance of solar shades were divided into three groups. Kirimtat and her colleagues said that module orientation is crucial in PVSDs, as it strikes a balance between power generation and the use of sunlight to reduce the heating, cooling, and lighting needs of buildings. However, given the fundamentals of new product development, the costs should be automatically lowered by the market, as the demand gets higher.” The implementation cost of conventional panels is very high for many customers and the tailor-made panels for shading devices would be considerably higher. ![]() ![]() “The basic criterion to consider before implementing such a system still is and will be the return of investment rather than sustainable energy development for green life. “Currently, the application of the solar panels to the kinetic shading devices is very limited so that is not possible to come across any instances implemented in the urban buildings, despite some prototypes,” researcher Ayca Kirimtat told pv magazine. An international research group has conducted a comprehensive review of all designs and control strategies for PV-integrated shading devices (PVSDs), in order to help bring the technology closer to commercial viability.
