A Novel Prediction Model for the Solar Radiation Absorptivity and Reflectivity of Cooling Photovoltaic Panels with a Water Layer

    The demand for efficient and sustainable solar energy systems is driving researchers to explore innovative solutions that enhance the performance of photovoltaic (PV) panels. One of the most common challenges in PV technology is overheating, which significantly reduces the panels’ energy conversion efficiency. To tackle this problem, scientists have developed a novel prediction model to study how a thin water layer affects the solar radiation absorptivity and reflectivity of cooling PV panels.

This approach is based on the principle that water can serve as a dual-purpose medium—cooling the panels to maintain optimal operating temperatures and modifying the way sunlight interacts with the surface. By combining optical physics with thermal analysis, the model accurately estimates how much solar energy is absorbed for power generation and how much is reflected away. Factors such as water layer thickness, solar incidence angle, and environmental conditions (temperature, humidity, wind speed) are considered to determine the ideal cooling setup for maximum efficiency.

The benefits of this innovation are significant. Cooler panels not only produce more electricity but also last longer due to reduced thermal stress. The model’s applications extend to floating solar farms, where water is naturally available, desert installations, where cooling is essential, and hybrid renewable energy systems that integrate solar with other green technologies.

By enabling precise performance predictions, this novel model empowers engineers and energy planners to design PV systems that are more efficient, durable, and sustainable. As the world transitions toward cleaner energy sources, such predictive tools will be instrumental in unlocking the full potential of solar power.

Experimental Study on the Effect of an Active Solar Heating Soil Heat Storage System on the Thermal Environment in Gobi Solar Greenhouses

Image
 Agriculture in the Gobi Desert faces extreme climate challenges, with scorching daytime heat, freezing nights, and limited water resources. To overcome these barriers, researchers have turned to innovative solutions such as Gobi solar greenhouses —structures designed to capture, store, and efficiently use solar energy for year-round cultivation. This experimental study investigates how integrating an active solar heating soil heat storage system can improve the thermal environment inside these greenhouses. In the research setup, solar air collectors harnessed energy during the day, transferring heat into an underground soil storage system via a network of pipes. This stored energy was gradually released at night, preventing sharp temperature drops that typically hinder plant growth in desert conditions. The results were striking—indoor air temperatures increased by up to 8°C at night, soil temperatures remained stable for root protection, and daytime overheating was reduced by ...

Capacity Planning of Hydro-Wind-Solar Hybrid Power Systems Considering Hydropower Forbidden Zones

Image
 Capacity Planning of Hydro-Wind-Solar Hybrid Power Systems Considering Hydropower Forbidden Zones As the global demand for clean energy intensifies, hybrid renewable energy systems are emerging as an efficient and sustainable solution. Among them, Hydro-Wind-Solar (HWS) hybrid systems stand out by combining the strengths of three powerful sources. However, integrating these systems requires sophisticated planning, especially when considering hydropower forbidden zones —areas where environmental, legal, or technical restrictions limit hydropower utilization. This blog explores the importance and strategy of capacity planning for HWS systems under such constraints. Understanding the Hybrid Approach A Hydro-Wind-Solar hybrid system brings together: Hydropower : Stable and controllable energy supply Wind energy : Cost-effective but variable Solar power : Abundant and predictable during daylight Together, they complement each other’s intermittency, resulting in a more ba...
