Math Connection
To use solar panels, engineers must first figure out how many they will need.
Let’s try it:
If a normal elementary school requires about 1,400 HWatts of electricity in a typical day, and one Solar PV panel can produce 50 Hwatts, how many solar panels would a school require? Explain your work.
1400HWatts ÷ 50HWatts = 28 solar panels
If each building on your campus can hold 10 solar panels, how many buildings would need to have Solar PB panels on them? Explain your work.
28 solar panels ÷ 10 panels per building = 2.8 buildings. Since you can’t have a fraction of a building, your answer would be 3 buildings with 10 solar panels on each of the first two and 8 solar panels on the third building.
