Answer:
The the smallest size of the collector is 25.64 m²
Step-by-step explanation:
Given that,
Total energy

Intensity

Efficiency = 26%
The intensity of light can be transformed to the required energy = Available intensity of light


We need to calculate the smallest size of the collector
Using formula of energy related to the intensity through area and time


Where, E= energy
I = intensity
= time
Put the value into the formula


Hence, The the smallest size of the collector is 25.64 m²
