Question

The solar cells I have supply 34 watts per square meter. 100 square meters will supply 100 x 34 = 3400 watts which is 3.4 kilowatts. How many square meters of solar panels would you need to 2 kilowatts?

Answer 1

2000 watts or 2 kilowatts will be supplied in 58.82 sq. meters

Step-by-step explanation:

1 kilowatt = 1000 watts

Therefore, 2 kilowatts =
`2 * 1000 \text { watts }` = 2000 watts

According to question,

3400 watts are supplied in 100 square meters

Then, according to the principle of unitary method:

2000 watts will be supplied in:
`(100 * 2000)/(3400) \mathrm{sq} . \text { meters }`

`(100 * 2000)/(3400)=58.82 \mathrm{sq.} \text { meters }`

Hence, 2000 watts or 2 kilowatts will be supplied in 58.82 sq. meters

Answer 2

The correct answer is 58.82 square meters of solar panels will be needed to supply 2 kilowatts

Step-by-step explanation:

Solar cell energy supply = 34 watts per square meter

Therefore, 100 square meters will supply 3400 watts which is 3.4 kilowatts.

How many square meters of solar panels would you need to 2 kilowatts?

Total energy = 2 kilowatts = 2,000 watts

Number of square meters = Total energy/Solar cell energy supply

Number of square meters = 2,000/34

Number of square meters = 58.82

It will be necessary 38.82 square meters of solar panels to supply 2 kilowatts
