A photovoltaic panel of dimension 2 m × 4 m is installed on the roof of a home. The panel is irradiated with a solar flux of GS = 700 W/m2, oriented normal to the top panel surface. The absorptivity of the panel to the solar irradiation is αs 0.83, and the efficiency of conversion of the absorbed flux to electrical power is Ƞ P/αsGSA 0.553 0.001 K -1Tp, where Tp is the panel temperature expressed in kelvins and A is the solar panel area. Determine the electrical power generated for a) A still summer day, in which Tsur T[infinity] 35C, h 10 W/m2⋅ K b) A breezy winter day, for which Tsur = T[infinity] = −15°C, h = 30 W/m2 ⋅ K The panel emissivity is 0.90

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.
