Abstract
The purpose of this case study is to research the effects of 500 KW solar photovoltaic investment in Xihu Township, Changhua County. The participants are four 500 KW solar photovoltaic power plants, Smile Pig Farm. The data were analyzed by Payback Period method, Net Present Value method, and IRR to evaluate the economic benefits about solar photovoltaic investment by the pig-raising dealer. With the overhead construction, it helps the pig house drop two to three degrees in summer, and reduce the raising cost about 300 dollars per pig. The results of the copmparative data of PV manufacturer''s electric power production are as follows.
1.Plant A has the best financial benefits. It recovers
acquisition cost in around 7.89 years; the NPV is
25,811,448 dollars, and the IRR is 11.15 %. The plant D
has less financial benefits. It recovers acquisition cost
in around 10.71 years; the NPV is 15,455,718 dollars, and
the IRR is 6.86 %.
2.The generated energy of the plant A is 655,331 kilowatt-
hour in 2013, feed-in tariff is 5,025,870 dollars, and
1KW is 3.6 kilowatt-hour. The plant A matches the
expected value. Besides, the generated energy of the
plant B is 94,661 kilowatt-hour from 30th May to 15th
July in 2014, and 1KW is 4.02 kilowatt-hour. The
generated energy of the plant C is 91,801 kilowatt-hour,
and 1KW is 3.91 kilowatt-hour. The generated energy of
the plantD is 96,961 kilowatt-hour, and 1KW is 4.12
kilowatt-hour. The 1KW of the plant B, C and D is
approaching 4 kilowatt-hour, and these three plants also
match the expected value.
3.Based on the results of angle of inclination positions,
different positions have different efficiency. From
January to May, 6∘of the southern position is greater
than 6 of the western position and greater the 6∘of the
northern position. From June to July, 6 of the northern
position is greater than 6∘of the western position and
greater the 6∘of the southern position.
In a word, for the pig-raising dealer, it is worthy to invest solar photovoltaic power plants when the wholesale price is over 5.2 dollars per degree, or the cost is under 3.5 %.
