Question

The graph bellow shows the actual solar product on a residential home. Each bar represents a 15 minute period of solar production from morning till evening. As the suns ray angle to the earth's atmosphere along with the angle to the solar array changes so does the power production. I have created a chart representing an 8 hour period each bar is one hour of production at 220 volts AC. Answer the following questions. For each hour of production what is the Power and current being produced? _____kwh_______________Amps ______kwh___________Amps

Explanation / Answer

Answer:-       Note:- 1 kWh = 3.6 x 106 Joule. Form given chart we can get value of energy, we convert it into power by dividing with the time and to get value of current we divide the power by 220 V.

For first data, energy is 0.5 kWh i.e 0.5 x 3.6 x 106 Joule = 1.8 x 106 Joule. Hence power is (1.8 x 106)/(8 x 3600) Watt = 62.5 W. Hence current value is 62.5/220 = 0.284 Amp.

1. 0.5 kWh, 0.284 A

2. 1 kWh, 0.568 A

3. 3 kWh, 1.704 A

4. 6 kWh, 3.409 A

5. 7 kWh, 3.977 A

6. 6 kWh, 3.409 A

7. 4 kWh, 2.273 A

8. 2 kWh, 1.136 A

Note:- Watt-Hour(Wh) is the unit of Energy, Watt(W) is the unit of Power.
