Within a photovoltaic (PV) module there are three main parasitic capacitances: • Capacitance between the grounded support frame and the PV cells. • Capacitance between the PV cells and the roof surface area. • Capacitance between the PV cells and moisture on the surface of the glass. The last capacitance, due to moisture is much higher than the other two capacitances (in wet conditions) and therefore the other two will be neglected for this problem. If there is sufficient moisture...
Consider the following configuration of solar photovoltaic arrays consisting of crystalline silicon solar cells 1H2 There are two subsystems connected in parallel, each one containing two cells. In order for the system to function, at least one of the two parallel subsystems must work Within each subsystem, the two cells are connected in series, so a subsystem will work only If all cells in the subsystem work. Consider a particular lifetime value to, and we want to determine the probability...

Please help to solving these question by excel sheet and
provide detail explain with the formulas. Thank you so much!
1. Why do we use free cash flows, instead of profits, when
evaluating the value of a company?
2. Explain what is the WACC in simple terms, and what its role
in valuation
3. In general, describe how to estimate a
company's valuation when the free cash flow are uneven the first
years, but later stay constant thereafter.

1)Thin film semiconductor materials for solar cells are made within a vacuum chamber which is pumped out in a process that removes as much of the air as possible (depending on the quality of the pump). Then high purity materials can be made that are free of contamination. In a typical pumping process, the pressure in the vacuum chamber is decreased to 1 x 10-7 Torr (1 Torr = 133.3 Pa) (See: en.wikipedia.org/wiki/Sputtering) Assume that the vacuum chamber and the...
1. In Module 2 "headers" and "footers" are described. Explain the difference between them and how to set them up. How can they improve your workbook's appearance? 2. A cell containing a number displays #######. Why does this occur and what can you do to fix it?
explain what is the difference between glycolysis in cancer cells ( The Warburg Effect) vs normal cells and how do you think this will impact the cells overall metabolism?
