Solar maps open up new possibilities for applications that use information about the sunlight. The most common application is the initial assessment of the potential of individual roofs of buildings for the installation of solar panels, as well as the assessment of the cost-effectiveness of this type of installation, depending on the shape and orientation of the building and its surroundings. Solar maps located in urban mapping portals also serve an educational function in society by promoting the use of renewable energy. Another use of solar map is town-and-country planning. Sunlight in the developed world begins to be seen as a precious good, which should be reasonably managed. Hence, there are also regulations to ensure residents adequate access to sunlight.
OPEGIEKA has begun work on the implementation of technology of solar mapping. As part of the pilot work there was made the Elblag solar map. On the basis of a detailed numerical model of land coverage made of laser scanning and the basis of meteorological data obtained from the Ministry of Transport, Construction and Maritime Economy, there has been calculated a yearlong potential of sunlight for the entire city (approx. 100 km2).
