How much power can be generated from a 14% efficient PV system occupying 25 square meters?

To determine how much power can be generated from a photovoltaic (PV) system, you need to understand how efficiency, area, and solar irradiance (power per unit area received from the sun) relate to each other.

In this case, the efficiency of the PV system is 14%, and it occupies an area of 25 square meters. The first step is to consider the standard solar irradiance value, which is typically about 1000 watts per square meter under peak sunlight conditions.

Using these figures, the total power that could potentially be generated by the system can be calculated using the formula:

[ Power = Efficiency \times Area \times Solar Irradiance ]

Inserting the given values:

[ Power = 0.14 \times 25 , \text{m}^2 \times 1000 , \text{W/m}^2 ]

Calculating this:

1. First, find the product of efficiency and area: [ 0.14 \times 25 = 3.5 ]

2. Next, multiply this result by the solar irradiance: [ 3.5 \times 1000 =
