Answer:

A 5kW solar system is made up of 20 solar panels, assuming that the panels have 250-watt capacity. The size of each panel will be approximately 1.6 m x 1 m, so at least 32 m² of roof space is needed to suit the space needs of this system.25 Oct 2021

Answer:

Part A: by finding equation and x value is size.

Take two coordinates: (20, 1/5), (40,2/5)

slope:

[tex]\frac{y2-y1}{x2-x1}[/tex]

[tex]\frac{\frac{2}{5} -\frac{1}{5} }{40-20}[/tex]

[tex]\frac{0.2}{20}[/tex]

[tex]0.01[/tex] ......this is slope, unit rate.

Equation:

y - y1 = m( x - x1 )

y - 1/5 = 0.01(x - 20)

y = 0.01x ........this is the equation

The y determines the size of kilowatts of energy

So y = 5

5 = 0.01x

x = 500 square feet

500 square feet is required to produce 5 kilowatts of energy.
