Photovoltaic Industry Situation And Its Technical And Economics Analysis

Photovoltaic as a new energy resource,is developing dramatically and playing a main role in the clean energy resources,with the 25-fold in accumulative installed scale in the past decade.The global installed scale in total in 2009 is 23 GW,while upto 400 GW in 2017.The development of photovoltaic in Hong Kong didn’t boom until year 2018 when Hong Kong government issued the Feed-in tariff policy which is expected to encourage the renewable energy resources,to increase the proportion of renewable energy in the power grid,to optimize the power supply structure,and promote sustainable social and economic development.Firstly,introduces the different stages of photovoltaic development in the world,especially Germany and Japan.Then,the history and current situation of China ’s photovoltaic development in detail from the perspective of installed capacity development and industrial chain development,from which,we learned that after years of development and integration,China ranks globally in terms of installed capacity and photovoltaic product output.also a big exporter of photovoltaic products.Then proceed to the development of photovoltaics in Hong Kong,analyze the constraints of development and the origin of the "Feed-in tariff" policy adopted by the Hong Kong government.Then,taking the rooftop photovoltaic project in Hong Kong as an example,carry out technical and economic analysis to demonstrate the technical and economic feasibility of the project;then use the financial analysis knowledge to make specific calculations on the project’s investment situation,total cost,project investment cash flow profit and profit distribution.The analysis shows that the project under the investment of nearly 2 million Hong Kong dollars can reach an important economic indicator conclusion that the financial internal rate of return is 38.7% and the pre-tax investment recovery period is 3.31 years,which proves the economic feasibility of the project.At the same time,the potential risks of the project are analyzed,and countermeasures for risk prevention or reduction are proposed to achieve controllable risks and ensure project benefits.
