Solution :
It is given that :
Thermal coefficient = 0.0045/K
Ambient temperature,

air velocity, v = 0-5 m/s
Solar radiation,


Model calculations :
Cell temperature (
)

where
wind speed / air speed
∴



= 35.526 - 25
= 10.526 K
Thermal coefficient = 0.0045 x 10.526
= 0.04737
Pv power =


= 17.0526 W
