A photovoltaic panel of dimension 2m×4m is installed on the
roof of a home. The panel is irradiated with a solar flux of GS =700W /m2, oriented normal to
the top panel surface. The absorptivity of the panel to the solar
Irradiation is s =0.83, and the efficiency of conversion of the absorbed flux to electrical power
is P /sGsA =0.553−0.001Tp, where Tp is the panel temperature expressed in Kelvins and A is
the solar panel area. Determine the electric power generated for
a. A still summer day, in which Tsur =T[infinity]=35C, h=100W /m2 â‹…K, and
b. A breezy winter day, for which Tsur =T[infinity]=−15oC, h=30W /m2 ⋅K. The panel Emissivity is 0.90.
