 Solar photovoltaic estimator for Africa. Some households in African rural and urban informal settlements live without electricity because they are not connected to the main electricity grid due to their location and distribution. In such cases, unsustainable environmentally harmful sources are used for light, heat and cooking. With increasing environmental consciousness and lowering solar energy costs, more and more people are turning to solar energy. This is particularly attractive in Africa, where the influence of the sun is greater than anywhere else in the world. We have developed a solution that recommends a solar system design based on the energy needs of a household and the solar radiation in its area. This is done through an end-user mobile application and advanced analytics cloud computing. Our solution helps to extend the provision of electricity across Africa in an environmentally sustainable way.
