How much is an acre of land by the way in general calculations for Solar PV system design?

1 Acre = 43,560 Sq.ft.

Now we need to know more about our Solar Panel rating and its size in order to understand the number of modules that can fit in an acre of the solar farm.

Let us take the Waaree Bifacial 540Wp PV module in our calculation –

solar mechanical characteristics

As it is a rectangle in shape, let us calculate its surface area using A = L*W

Where

A is an area of a rectangle

L is the length of one side of a rectangle

W is the width of one side of a rectangle

In our case

L = 2272mm

W = 1133 mm

Hence,

Area = 2272*1133

= 25,74,176 mm2

= 27.7 Sq ft.

Now let us calculate the number of 540 Wp Waaree PV modules that can fit in one acre of the solar farm.

From previous conversions,

1 Acre = 43,560 sq. ft.

In order to know the number of PV modules that can fit in the 1-acre farm, we need to divide the total area by the area of one solar module.

That is,

The Number of PV modules that can fit in One-acre farmland = 43560/27.7

= 1572.6 ~ 1573 PV modules can be installed in one-acre farmland.

Now as we know that each module is of 540Wp power rating so we can easily calculate the total capacity of our PV power plant that can be installed on a one-acre solar farm.

The total capacity of a PV power plant = 1573*540 = 8,49,420 Wp ~ 850 kWp
