Advanced cooling technique to improve efficiency of Solar Panel

Increased energy demand due to demand from industry, home use, etc. Not satisfied with just that traditional resource. Hence, alternative energy resources will also increase; to satisfy this demand solar energy is a critical energy. This paper look into different techniques used to improve the thermal efficiency of a solar module to improve the efficiency. Solar panels are one of the renewable energy sources. Green energy (sunlight) is converted to electrical energy without the presence of mechanical energy. Energy created by Photovoltaic panels varies with the variation in the intensity of solar radiation received by the panel and the temperature of the photovoltaic surface. The module has a nonlinear voltage-current characteristic with a single point at which the source product is the maximum. Temperature and radiation levels of the module affect the maximum power point. Different geographical areas and seasons or time of year have different effect on these conditions. Many studies have been carried out on enhancing the efficiency of solar panels by cooling photovoltaic cells using different cooling techniques like- running water through tube on surface of panel at different rates, submerging the panel in fluids, using wet sponges or water holding things and keep it in contact with the panel's surface, etc. All these techniques have helped in improving the efficiency of panel. Here the real time mentoring can be done by the use of IoT with Raspberry Pi cheap which can be used to inculcate multiple sensors which can be used to track the temperature of solar panel and hence command the respective actuators to perform cooling actions. Such as turning on pumps or fans.
