在本系列的第二部分中，据报道，REB在纳辛迪区Meghna河的一些岛屿上提供的太阳能家庭系统（SHS）在雨季天空仍然阴云密布时无法满足接受者的需求。所有装置的倾斜角为45°，面向南方。在这项研究中，使用单晶硅电池研究了倾角从0°到45°变化的直射和漫射阳光的影响。日射强度计和太阳能电池板保持在相同的条件下。太阳能电池板在漫射太阳光中吸收的能量是日射强度计在类似条件下接收的能量的0.55%，这表明所研究的单晶硅太阳能电池类型不适合用于SHS。此外，面板与其下方的固体表面之间的差距对太阳能电池的效率具有显著影响。进一步类似的研究，使用不同类型的细胞-单晶，多晶和非晶的SHS的适当设计是必要的。对于屋顶安装和地面安装的面板，面板和其下方的固体表面之间的差距的优化是重要的。关键词：硅太阳能电池;矩形;漫射光;家居照明;单线。DOI：http://dx.doi.org/10.3329/bjsir.v46i1.8114 Bangladesh J.

In part II of this series, it was reported that the solar home system (SHS) supplied by REB in some islands of the Meghna river in the district of Narsingdi could not meet the demand of the recipients in the rainy season when the sky remained overcast with cloud. The tilt angle for all installations was 45° facing south. In this study, effects of direct and diffuse sunlight with variation of tilt angles from 0° to 45° were studied using a mono crystalline silicon cell. Pyranometer and the solar panel were kept under identical conditions. Energy absorbed by the solar panel in diffuse sunlight was found 0.55% of that received by the Pyranometer under similar conditions showing that mono crystalline silicon solar cell of the type under study was not suitable for use in SHS. Moreover, the gap between the panel and the solid surface below it has significant effects on the efficiency of the solar cell. Further similar study using different kinds of cells- mono crystalline, poly crystalline and amorphous is needed for proper designs of SHS. Optimization of the gap between the panel and the solid surface below it is important for roof-mounted and ground-mounted panels.
