“…The total roof area in this category is 19,721.36 (23.33% of the total area of all roofs). The second most numerous group is roofs with annual solar potential in the range of 382,579 Wh/m 2 -508,700 Wh/m 2 -103 objects (group II)-the area of which is 18,808.41m 2 (22,25% of the surface of all roofs) Values of solar radiation potential at a similar level are also in the range 742,646 Wh/m 2 -944,887 Wh/m 2 (group V)-the area of which is 19,171.90 m 2 At least for the large group, they constitute roof patches, and the amount of solar energy falling on their surface is 944,888 Wh/m 2 -1,225,944 Wh/m 2 (group VI) and 41,196 Wh/m 2 -382,578 Wh/m 2 (group I) during the year. The solar potential values can be different in neighboring buildings because, when calculating solar intensity, parameters such as the height of buildings, aspect, slope of roofs, size of roofs, number of roofs' patchesare taken into account.…”
