Photovoltaic solar energy requires:
- A.
Water
- B.
Connection to the electricity grid
- C.
Wiring
- D.
Moving parts
Correct Answer(s)
A. Water
B. Connection to the electricity grid
C. WiringExplanation
Solar PV panels are the only means today of generating electricity without moving parts. True, they require very little water (just enough to keep surfaces clean) and can be used for living off the electricity grid, but the same is true of wind energy.Rate this question:
