Solar technologies offer clean and sustainable energy production at an affordable cost. Therefore, their use is rapidly growing, and private users as well as local authorities demonstrate wide interest in identifying areas suitable for mounting solar modules. The recent improvements of remote sensing techniques such as LIDAR (Light Detection and Ranging), are very attractive and suitable for solar potential assessment; however, it is of paramount importance to transfer the knowledge to the public. The proposed solution includes the development of an interactive tool, Solar WebGIS, which can analyse and visualize solar potential characteristics. Furthermore, the article discusses the data preparation, integration, and visualization issue related to the WebGIS.
