Solar energy is immensely available during daytime on the earth. It is a sustainable, renewable and green energy. Improvement in efficiency of harnessing solar energy is the utmost concern of the present research due to its renewable nature. This article presents a complete utilization of solar irradiation over the broad spectrum of solar energy efficiently. The design, development and implementation of the hybrid solar photo voltaic & thermal (SPVT) system are reported, in which a tandem structure of transparent solar panel and large Fresnel lens concentrator are mounted for sunlight harvesting. In this hybrid system a semi-transparent solar panel mounted on the top for PV application and large Fresnel lens is for concentrating the transmitted light onto a solar thermal absorber unit for heating water efficiently. The partial visible portion of solar energy is converted into voltage generation using semi transparent solar panel (TSP) while remaining transmitted radiations is further concentrated by a large Fresnel lens which was fixed below semi-transparent solar panel. Concentrated sunlight was focused on solar thermal unit which was utilized for water heating. Two different color filter semi-transparent solar panel modules were integrated with the system for testing and reported that the red color filter solar panel generates more power and overall efficiency as compared to other one. Experimental results using the prototype developed system are reported. Due to simultaneous electricity generation and domestic hot water application the hybrid system becomes more efficient, robust and cost effective for sustainable development of the country.

太阳能在地球上的白天非常可用。它是一种可持续、可再生和绿色能源。由于太阳能的可再生性质，提高利用太阳能的效率是当前研究的最大关注点。本文介绍了在太阳能的广谱范围内有效地完全利用太阳辐射。报告了混合太阳能光伏和热 (SPVT) 系统的设计、开发和实施，其中安装了透明太阳能电池板和大型菲涅耳透镜聚光器的串联结构以收集阳光。在这个混合系统中，安装在顶部的半透明太阳能电池板用于光伏应用和大型菲涅耳透镜，用于将透射光集中到太阳能热吸收器单元上，以有效地加热水。太阳能的部分可见部分使用半透明太阳能电池板 (TSP) 转换为电压生成，而剩余的透射辐射由固定在半透明太阳能电池板下方的大型菲涅耳透镜进一步集中。集中的阳光被聚焦在用于水加热的太阳能热装置上。两种不同的滤色器半透明太阳能电池板模块与系统集成进行测试，并报告说红色滤色器太阳能电池板与其他太阳能电池板相比产生更多的功率和整体效率。报告了使用原型开发系统的实验结果。由于同时发电和生活热水应用，混合系统变得更加高效、稳健和具有成本效益，有利于国家的可持续发展。
