The annual average insolation for a fixed solar panel in
city A is 350 W/m2. On the other hand, city B has a figure
of 300 W/m?. For both locations, the solar panel has the
capability to convert 17% of the incident energy into
electricity. Average annual electricity in City A is 13 000
kWh with an average cost of $0.4/kWh, while in city B, it
is 10 000 kWh at a cost of $0.75/kWh.
For City A,
a. Determine the area of the solar panel needed in order
to suffice the average electrical needs of a residence.
b. Determine the area of the solar panel needed in order
to suffice the average electrical needs of a residence in
City B.
c. Determine the price per square meter of solar panel in
City A if the device has a lifetime of 20 years. Assume
that the electricity costs are constant throughout the
period.
d. Determine the price per square meter of solar panel in
City B if the device has a lifetime of 20 years. Assume
that the electricity costs are constant throughout the
period.
On a summer day, the mean solar irradiance received at a lake was 500 W/m^ 2 over 25 days (consider the day length to be 8 hours). If 80% of the energy is used to vaporize water, how large could the depth of evaporation be?
A 2 x 2 m flat plate solar collector for domestic hot water heating is shown in the figure. The incident solar radiation on the glass cover, which transmits 90% of the incident flux, is 750 W/m2. Water flows through the tubes soldered to the backside of the absorber plate, entering at a temperature of 25°C. The temperature of the glass cover is 27°C, and it radiates heat with an emissivity of 0.92 to the sky at –50°C. Additionally, the glass cover losses heat by convection to air at 20°C flowing over its surface at 30 km/h. Assume that the radiation heat transfer between the absorber plate and glass cover and the heat transfer through the back and sides of the collector is negligible.
