The study shows that rooftop solar can meet 51.19% of annual energy demand for a commercial building at optimal orientation.
With a 0° tilt angle for rooftop solar, energy generation exceeds that from a 15° tilt angle, achieving better overall performance.
Energy production from vertical facades at actual orientation is measured at 611 kWh/kWp/year, demonstrating effective use of space.
Economic analysis indicates that after 30 years, the solar integration generates significant net savings, with 35.24% savings achieved.
