You are serving as an expert witness for the city council of a community. The council is exploring the concept of providing the electrical needs of the community by building a facility with photovoltaic cells to convert sunlight to electric potential energy. But they are facing resistance from members of the community, who claim that there is not enough open land in the community to build such a facility. The opposition is building toward a lawsuit, which the city council wants to avoid. The community requires 2.20 MW of power, and the best photovoltaic cells on the market at the time have an efficiency of 30.0%. In your community, an average intensity of sunlight during the day is 1,030 W/m2. The council members have no idea how much land is needed, so they have asked you to estimate the area of land (in m2) that must be found to construct this facility. (Assume the given average intensity of sunlight is only available for eight hours a day.)
Car manufacturers are developing engines that use H2 asfuel. In Iceland, Sweden, and other parts of Scandinavia, wherehydroelectric plants produce inexpensive electric power, the H2 can be made industrially by the electrolysis of water(a) How many coulombs are needed to produce 3.5x10^6L of H2 gas at 12.0 atm and 25°C? (Assume the ideal gas law applies.)(b) If the coulombs are supplied at 1.44 V, how many joules areproduced?(c) If the combustion of oil yields 4.0x10^4kJ/kg, what mass ofoil must be burned to yield the number of joules in part (b)?
a) Can you explain to me in detail the P-I (Power-Current), PV ( Power-Voltage) and I-V (Current-Voltage) characteristics of a Photovoltaic Cell,
b) as well as the effect that Solar Irradiance has on the solar cell's maximum Power Generated (Pmax) Maximum Current (Imax) Maximum Voltage (Vmax) Open Circuit Voltage (Voc) and Short Circuit Current (Isc).
c) What is the effect that solar irradiance and temperature variation has on the P-V and I-Vcharacteristics of a solar module.
d) What is the effect of Partial Shading on the Photovoltaic model performance?

- (a) Calculate the power per square meter reaching Earth's upper atmosphere from the Sun. (Take the power output of the Sun to be 4.001026 W.) (b) Part of this is absorbed and reflected by the atmosphere, so that a maximum of 1.30 kW/m2 reaches Earth's surface. Calculate the area in km 2 of solar energy collectors needed to replace an electric power plant that generates 750 MW if the collectors convert an average of 2.00% of the maximum power into electricity. (This small conversion efficiency is due to the devices themselves, and the fact that the sun is directly overhead only briefly.)
