Question

If a solar photovoltaic panel produces 1,000 watts of electrical energy and is active for 12 hours each day, how many kWh of electricity will be produced in a week? (a) 63 kWIh (b) 12 kWh (c) 84 kWh (d) 70 kWh (e) 7 kWh

Answer 1

The answer is c) 84 kwh

Step-by-step explanation:

The total Energy in kilowatts-hour, s equal to the power P in kilowatts (kW), times the time period t in hours.

E= P(kw)*t(h)

E=
`1000watts*((1KW)/(1000watts)) *((12hr)/(day))= 12(KWh)/(day)`

Then, Calculate for a week (7 days)

E=
`12(KWh)/(day) *(7days)=84KWh`

The final result is 84KWh
