Hi.
00:01
In the first part of this question, they're saying that an average modern photovoltaic solar panel will produce 18 to 20 watts per square foot of solar panel area.
00:13
So if we let that minimum intensity is 18 watts per feet squared, and the maximum intensity is 20 watt per feet squared.
00:30
So here, if the roof area is 6 meters by 10 meters, so area is given as 6 meters by 10 meters.
00:40
Then we have to calculate the value of the electric power it will produce.
00:46
So here, the average intensity will be 18 plus 20 divided by 2.
00:55
So we get this as 19 watt per feet squared.
00:59
Now, the minimum power, that is p minimum, will be i minimum into a, which is area.
01:09
So we can just calculate this as 18 into the value of area.
01:18
So we can calculate the value of area as 6 into 10, which is 60 meters squared.
01:25
Or we can write this as 645 .835 feet squared.
01:31
So now we can calculate the value of minimum power as 18 into 645 .835, which gives this value as 11 .62 kilowatt...
