Solar panels are proposed to be installed on a building roof top to generate electricity. The size of each solar panel is 2 m2. The efficiency of each panel is 75%. The orientation of the solar panel and related solar data are given in the table below. As per above proposal ______ kWh solar power will be generated daily (rounded off to one decimal place).
-
- 28.5
- 14.5
- 7.5
- None of the above
Correct Option: A
Solar power generated = Average solar radiation × Area × Average solar hours × Efficiency
Solar power from the south orientation = 400 × 20 × 4 × 0.75 = 24 kWh
Solar power from the West orientation = 300 × 10 × 2 × 0.75 = 4.5 kWh
Total Solar power generated = 24 + 4.5 = 28.5 kWh
