Q1: What is the primary process of converting solar energy into other form of energy, explain and give an example of each one of them? Q2: Determine the Sun's altitude angle , azimuth angle, and zenith angle at 5.00 P.M on December 15, 2017 for a location at 24.85° N latitude. Q3: Compare the power generated by the two shown systems 1 and 2, if each turbine have air velocity in that area was V= 5 m/sec and the air density p=1.19 kg/m³m while in system 2 to increase the air velocity we uses a truncated cone of area ration A1/A2=4. blades 5 m length, while the

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.

The heat exchanger radiates thermal energy at the rate of 2500 kJ/h for each square meter of its surface area. Determine how many joules (J) are radiated within a 5-hour period.
