The Total projected Energy Consumption is

3,00,000+2,64,264 kwh

According to Govt. of Telangana only 500 kwh per day can be installed This is 9% of the Total Consumption This makes the Installation SUPER ECBC compliant. According to Table 7-6 Minimum Solar Zone Area/Renewable Energy Generating Zone Requirement for SuperECBC Building According to the Roof Coverage 62% will be covered with Solar PV Panels According to the Analysis with Solar Glare Analysis Tools, the best orientation is at 180° and at a tilted angle of 30° to normal.
