The main objective of this work is to create a daily updated database that includes all components of solar radiation, either energetic or spectral radiation. This will lead us to quantify the Moroccan solar potential and to determine the dimensions of all types of solar thermal and photovoltaic systems. Consequently, the obtained database will be the fundamental support for engineers, designers, and all organizations interested in developing solar systems, in different regions throughout Morocco. It will also be a basic tool for researchers in modelling and simulating the new solar systems. Firstly, we used one year’s worth of measurements of the different components of the solar radiation, provided by the National Meteorological Department, to establish the extrapolation equations between the global radiation at the reference site and the global radiation of twenty-eight other sites. As well as with the same measurements, we developed the correlation equations between the global solar radiation and the other solar radiation components. Secondly, from ten years of Fez station’s daily global radiation measurements and through the extrapolation equations, we were able to estimate the global radiation of all Moroccan cities. Then, by using the obtained global radiation data and the correlation equations, we predicted the other components of solar radiation. Subsequently, with a new measurement campaign carried out on several sites, we validated the estimation models by using the usual statistical indicators. In addition, we compared our results with those obtained by other estimation models. The resulting differences for each solar component display the advantage of our model with errors under 6%. To facilitate the use of our results, we compiled them into maps representing the spread of solar radiation across Morocco.

为摩洛哥领土开发每日太阳辐射成分数据库

这项工作的主要目标是创建一个每日更新的数据库，其中包括太阳辐射的所有成分，无论是能量辐射还是光谱辐射。这将引导我们量化摩洛哥的太阳能潜力，并确定所有类型的太阳能热和光伏系统的尺寸。因此，获得的数据库将成为摩洛哥不同地区的工程师、设计师和所有对开发太阳能系统感兴趣的组织的基本支持。它也将成为研究人员建模和模拟新太阳系的基本工具。首先，我们使用了国家气象部门提供的一年来对太阳辐射不同成分的测量值，建立参考站点的全球辐射与其他 28 个站点的全球辐射之间的外推方程。与相同的测量一样，我们开发了全球太阳辐射与其他太阳辐射分量之间的相关方程。其次，根据菲斯站十年的每日全球辐射测量数据，通过外推方程，我们能够估算出摩洛哥所有城市的全球辐射。然后，利用获得的全球辐射数据和相关方程，我们预测了太阳辐射的其他成分。随后，通过在几个站点上进行的新测量活动，我们使用常用的统计指标验证了估计模型。此外，我们将我们的结果与其他估计模型获得的结果进行了比较。每个太阳能组件的结果差异显示了我们模型的优势，误差低于 6%。为了便于使用我们的结果，我们将它们编译成代表整个摩洛哥太阳辐射分布的地图。
