Conclusions A combined solar fiber lighting and photovoltaic power generation system based on spectral splitting (SSLP) technology has been proposed in this study, with visible light for house lighting and near-infrared light for photovoltaic power generation.
The automatic sun-chasing panel can effectively improve the utilization of solar energy by adjusting the robotic arm that keep a right angle towards the sunlight.
Shen et al. developed a solar lighting/heating system that uses a hollow lens filled with ATO nanofluid to separate long wave and short wave in sunlight, and can achieve an additional 25.35 % photothermal conversion efficiency by recovering energy from non-visible light while achieving illumination. 1.3. Limitations and research gaps
This system was divided into light sensing, light comparison, control, and movement adjustment units. The light sensing unit comprises five sensors to measure the light intensity and generate a corresponding analog voltage signal. Two pairs of LDRs were used as sensors to track the exact position of the sun.
The light-intensity-sensing method was utilized to boost the efficiency of solar conversion by up to 100% during summer and up to 40% during winter. A tracker system that contains a stepper motor, an H-bridge, and a buffer amplifier, was built for research. The proposed neural network model was tested in a un real-time environment for evaluation.
Therefore, by dividing sunlight into visible and near-infrared wavelengths through spectral splitting technology, the overheating problem can be significantly reduced while ensuring the efficient transmission of sunlight, and solar utilization can also be improved through photovoltaic power generation.
