Solar electricity cost.

Despite all the advantages of using solar cells to harvest solar energy, solar electricity still has an insignificant share (~1%) in the world’s overall energy supply picture. This is mostly due to the economic consideration. While there’s virtually no fuel (sunlight) cost and maintenance cost once the solar panels are installed, the initial cost of solar electricity systems is still the obstacle for wide-spread adoption of solar photovoltaic technologies.

a. Use the single-crystalline Si solar panels as an example. Typical module fabrication cost is $150/m2, and typical efficiency is 15% (the commercial panel efficiency is significantly lower than the efficiency of champion laboratory cell; why?). Calculate the cost of the solar panels in terms of $ per peak power output ($/WP). [Hint: what is the optical power intensity for AM1.5 global spectrum?]

b. Assume all the other cost items (transportation, installation, and other Balance of Systems such as inverters, meters, etc.) is about 150% of the panel cost. A typical panel lifetime is 25 years. In Gainesville, we get about 2000 hours per year sunlight at standard AM1.5G power (1 kW/m2). Calculate, over the lifespan of the solar panels, how much is the cost of the solar electricity in terms of cents per kWh.

Explain how the Touch-Tone Telephone works when we dial a number; how it is transmitted to the telephone office.

Part 1. MATLAB Programming The wind chill factor measures how cold it feels with a given air temperature T (in degrees Fahrenheit) and wind speed (V, in miles per hour). The formula is approximately

?????? = 35.7 + 0.6?? ? 35.7(??0.16) + 0.43??(??0.16)

a). Write a function that will calculate the wind chill factor (WCF) given temperature and wind speed. Your function should round down to the nearest integer.

b). Write a script that will use the function above to create a table of wind chill factors, similar to the one shown at https://en.wikipedia.org/wiki/Wind_chill#/media/File:Wind_chill.png. Wind speed should be down the left and temperature across the top. PLEASE SHOW OUTPUT THANKYOU

1. Write code in mips that will play battleships. Include comments in code on what each part is doing.

A) Convert the binary (0100011011) to Hex and multiply it by A8H B) Subtract (0011101111010010) your answer in A)

Listen to the audio signal x6 using the soundsc command. In your report, describe the perceived sound and explain your results.

Pass the signal x5 through the filter h using the command: x6 = filter(h,1,x5); In your report, include a plot of the amplitude spectrum of x6 (use the normalized frequency axis as you did for previous parts of this project).

Consider the discrete-time filter defined by h = fir1(40,0.2). The coefficients h represent a 40th order filter, with a corner frequency of 0.2 times the Nyquist frequency. Use Matlab help on fir1 to learn more about this command. Plot the frequency response of the filter h using the command freqz. Include this plot in your report.

Design a controller that detects the four-bit, binary MSB first serial sequence of the rounded average of the last digits of the team members' Social Security Numbers. You should use a switch in the Nexys4 DDRTM FPGA Board to mimic a clock pulsed. The input bit should be setup before the clock pulse

How could I create a Powe supply of aproximable 5V DC output with atleast 100mA with a max variacion of 7% with an input of 120V rms with 60hz

Please explain the process and the example on multisim

You are given two bandpass filters The first has a 5-pole Butterworth topolgy with a 10% bandwidth. The second has a 5--pole Chebyshev topology with a 10% bandwidth. Using you knowledge of microwave filters, qualitatively analyze the performance of each and comment on which one would be most useful in providing the maximum out-of-band attenuation to a signal that is 75% of the center frequency
