A photovoltaic panel of dimension 2m X 4m is installed on the roof of a home.the panel is irradiated with a solar flux of Gs=700 W/m^2,oriented normal to the top panel surface.the absorptivity of the panel to the solar irradiation is alpha(s)=0.83,and the efficiency of conversion of the absorbed flux to electrical power=P/(alpha(s)*Gs*A)=0.553-0.001K^-1*Tp,where Tp is the panel temperature expressed in kelvins and A is the solar panel area.Determine the electrical power generated for a)still summer day,in which T(surr)=T(infinity=35C,h=10 W/m^2.Kb)a breezy winter day,for which T(surr)=T(infinity)=-15C,h=30 W/m^2.K.the panel emissivity is =0.90
