Question

Question 2 Portugal has a typical insolation of 1000 W/m2. A solar PV plant located there has an output of 11 MWp. Since the collectors track the sun, the power output is steady at 11 MW from 09:00 to 16:00 Hrs and almost zero outside this time. The lifetime of the system is 20 years with an annual operating cost and total capital investment of €1 million and €75 million, respectively. The cost of capital is 7% p.a. The efficiency of the collectors and distribution system is 15%. 90% of the electricity generated is delivered to customers. If the solar plant did not exist, the electricity would have to be generated by an oil-fired steam turbine with 40% efficiency. Oil C12H26 has a calorific value of circa 40 MJ/kg iv. How many tons of CO2 would such a steam plant emit per year? V. What is the cost of the electricity generated by the plant (/KWh)?
