在某个地方的太阳辐射的知识是太阳能系统，无论是热的和光伏的合适位置的基础。在局地尺度上，地形是地表太阳辐射的最重要的调制因子。在这项工作中，全球每日照射估计各种天空条件下，在复杂的地形区域。为了估计全球每日辐射，我们使用的方法的基础上的数字地形模型（DTM），一方面利用总日射强度计测量，另一方面利用卫星图像。我们强调，DTM应用采用日射强度计测量产生更好的结果比估计使用卫星图像，虽然精度相同的顺序，在这两种情况下获得的均方根误差（RMSE）和平均偏差误差（MBE）。
The knowledge of the solar irradiation in a certain place is fundamental for the suitable location of solar systems, both thermal and photovoltaic. On the local scale, the topography is the most important modulating factor of the solar irradiation on the surface. In this work the global daily irradiation is estimated concerning various sky conditions, in zones of complex topography. In order to estimate the global daily irradiation we use a methodology based on a Digital Terrain Model (DTM), on one hand making use of pyranometer measurements and on the other hand utilizing satellite images. We underline that DTM application employing pyranometer measurements produces better results than estimation using satellite images, though accuracy of the same order is obtained in both cases for Root Mean Square Error (RMSE) and Mean Bias Error (MBE).
