Problem 4P
At a certain location, the solar power per unit area reaching Earth’s surface is 200 W/m2, averaged over a 24-hour day. If the average power requirement in your home is 3 kW and you can convert solar power to electric power with 10% efficiency, how large a collector area will you need to meet all your household energy requirements from solar energy? (Will a collector fit in your yard or on your roof?)
Step-by-Step Solution:
Step 1 of 3
Solution 4P The average requirement of my home is = 3 kW = 3000 W But only 10% of solar power is converted to electric power. Therefore, to obtain 3000 W of power, the incident solar power on the collector has to be = 3000...
