With the aid of well labeled diagrams, explain the principle of operation of: a. a pyranometer. b. a wind turbine, from resource to electrical power

Answer all the questions (a) How much power is the wind farm generating? (b) How much power is the solar farm generating? (c) Find the power delivered to the AC motor. (d) If the AC motor requires at least 45 kW of power, is the system able to provide that power? If not, how many additional series PV modules should be added to each string (we want to keep the same number of modules in each string)? If so, how many modules can be removed from each string while still meeting the requirements?
