A device for performing solar shade analysis combines a spherical reflective dome and a ball compass mounted on a platform, with a compass alignment mark and four dots in the corners of the platform. A user may place the device on a surface of a roof, or in another location where solar shading analysis is required. A user, while standing above the device can take a photo of the device. The photographs can then be used in order to evaluate solar capacity and perform shade analysis for potential sites for solar photovoltaic systems. By using the device in conjunction with a mobile device having a camera, photographs may be taken and uploaded, to be analyzed and processed to determine a shading percentage. For example, the solar shade analysis system may calculate the percentage of time that the solar photovoltaic system might be shaded for each month of the year. These measurements and data, or similar measurements and data, may be valuable when applying for solar rebates or solar installation permits.
