A new, simplified photographic method is proposed to estimate the shading effects of obstructions. In spite of the complex mathematical background of thenew tool, its practical application is very simple, and only requires the measurements of three angles for each photograph. The proposed method isparticularly useful for overcoming the difficulties caused by the need to accurately describe surrounding objects to estimate shading effects. The newmethod uses the information contained in a picture and allows one to draw daily solar paths directly on the photograph. The procedure is useful to verify thesuitability of a generic site for solar exploitation; its main benefit is the simplicity of use and the transparency of the obtained results. This simple method is alsoparticularly suitable to evaluate the technical feasibility of small solar equipment, which would not require complex software to define the daily solar path.
