The Economic Research Of Domestic Solar Central Hot Water System Of X Company

With global warming and energy shortages are becoming increasingly severe, with its limitless solar energy, extensive and cleaning of an ideal alternative energy sources. In recent years, many companies put forward the concept of solar energy central hot water, namely the use of solar energy to provide hot water for the residential and heating, greatly saving gas energy consumption. However, due to solar energy resources by geographic factors, their performance, as well as local gas prices, resulting in different regions of the central heating system using solar system relative to the gas relative to income is different, and even may not be economical.X Corporation is headquartered in the United States engaged in environment protection and energy of the world fortune 500 companies, in recent years, with the booming solar market, X's timely introduction of the A-type solar energy central hot water system is split, with A-15 type of vacuum tube collectors.This paper studies the X's solar water heating products in the different cities of the relative income model, first established and geographical factors and features related to the annual collection tube heat model, the specific market conditions combined to create revenue models. Then the A-type solar energy central hot water system design parameters into the model to the Chinese mainland's 26 provinces and cities as the representatives of the provincial capital, to calculate the economic benefits, of which positive regional economic benefits for the efficient market. This solar hot water and central market capacity in the provinces to estimate the final map out effective market curve. Finally, we discuss when the increase in government subsidies for solar water heating systems, the effective increase of the market. The main contribution of this paper and innovation are as follows:1. For the solar energy resource in China is the lack of statistical data in the case, the establishment of an annual set of vacuum tube collector heat calculation model. Can be achieved for any region, any placement, any manufacturer of vacuum tube heat collector for years set the calculation.2. solar and gas hot water system as a comparison of the relative investment, net present value theory, the introduction of the exact period of their life doing economic analysis.
