The Smart Sliding Dual-Layer Luminescent Solar Concentrator (LSC) Rooftop System represents a breakthrough innovation in the future of agrivoltaics as it merges agricultural productivity with renewable energy generation in a single intelligent solution. Installed exclusively on greenhouse rooftops, this system is designed to maximise the efficiency of sunlight utilisation by delivering the right spectrum for healthy plant growth while at the same time harvesting solar energy. Through this integrated function, the system transforms greenhouses into self-sustaining powerhouses that directly support sustainable agriculture. The challenge addressed by this project arises from the limitations of conventional rooftop LSC panels which remain static and cannot adapt to changing sunlight conditions. This limitation forces growers to choose between electricity generation and plant growth, resulting in reduced yields whenever too much light is diverted into energy. Such a conflict between productivity and sustainability highlights the urgent need for a smarter and more dynamic rooftop system. The objective of this project is to create a responsive LSC rooftop that can intelligently balance energy harvesting and light transmission in real time. By regulating the proportion of sunlight directed towards electricity production and photosynthesis, the system ensures that crops receive the optimal spectrum needed for healthy development without sacrificing renewable energy output. The system employs two LSC layers integrated within a sliding rooftop frame. The first layer transmits the essential red and blue wavelengths crucial for photosynthesis while converting less-useful ultraviolet and green light into electricity. The second layer is mounted on a sliding mechanism which can automatically adjust its position through a Light Dependent Resistor (LDR) sensor and actuator. This feature enables the rooftop to cover or uncover the first layer depending on sunlight intensity, thereby offering growers precise control over rooftop light levels that can be tailored to crop type, growth stage and prevailing weather conditions. The novelty of this innovation lies in its dual-layer sliding mechanism which is not available in traditional greenhouse solar panels. Its usability lies in the ability to provide farmers with flexible and automated rooftop management that adapts naturally to both environmental changes and agricultural requirements. From a commercial perspective, this system offers significant potential value. It can lower operational energy costs, improve yields and integrate automation, making it highly attractive for large-scale agriculture, urban farming and smart farming ventures. Beyond its economic advantages, the system also supports global goals for food security and climate action. In essence, this project delivers more than a product as it introduces a smart rooftop revolution that empowers farmers, reduces costs and drives the future of sustainable agriculture.
