Photovoltaic power station is a new type of investment way, during the 20 years of operating, trap to remove the force majeure cause plant damage loss risk factors, its long-term objective of income is very stable, therefore has attracted more and more investors. But the photovoltaic (pv)
photovoltaic power station is a new kind of investment. In its 20 years of operation, eliminate the force majeure and other may cause damage to the plant and the loss of risk factors, its long-term earnings is very stable and objective, therefore has attracted more and more investors. Photovoltaic power stations, however, investment is also have the characteristics of high investment cost, long payback period, which greatly limits the investor's investment confidence. In general, plant income comes from enterprise electricity, electricity and electricity subsidies income online, but the risk runs through the whole construction and operation of power station project period, so must be ready before project implementation project investment evaluation. Directly affect power station income is income = companies charge + Internet charge + kilowatt hour subsidies income. Among them, enterprises for electricity generation x = use ratio by Internet charge = generation x remaining power ratio x = KWH electricity price subsidies income online generation x KWH subsidies. According to the above formula, the plant capacity and the price level ( Kilowatt hour subsidy national unity, the enterprise electricity and feed-in tariff varies from area to area, are referred to as the electricity price level) And for private use ratio is 1. And the solar radiation on generating stations, the conversion efficiency of photovoltaic modules and photovoltaic power generating capacity of components attenuation. Irradiation is judge whether an area suitable for investment important natural factors of photovoltaic power station. China is rich in primary area of solar energy resources, the same condition, power plant capacity is much higher than level 3 resources area. In addition, the components of conversion efficiency is also the important factors that affect generating. Monocrystalline silicon components of the conversion efficiency higher than that of polycrystalline silicon components, but costs are higher monocrystalline silicon components. At present, the distributed photovoltaic market still is given priority to with polysilicon components. Generally speaking, in the same price level and the proportion of the same plant for private use, the unit capacity is higher, the greater the power plant yield. 2. Electricity price level at present, most of the provinces and cities and large industry general peak at valley valley of electricity and the peak power ratio, feed-in tariff feed-in tariff calculation according to the local coal-fired units. The higher the price, the unit capacity and power station under the same proportion of spontaneous for private use, the greater the benefits of power plant. 3. For personal use and for personal use is associated with the following factors: the proportion of the annual electricity consumption, power generating capacity, daily working hours, annual leave days, and factory equipment during the period of rest is full. The higher the proportion of the (for personal use and for private use The enterprise use photovoltaic power consumption is higher) , the higher the power station income. In general, power generation and electricity price level is an important factor to determine project development area, the local government's support and the level of economic development is also very important reference index. After determine the development of the project area, whether on a single project worth the investment, it is necessary to evaluate project for spontaneous use estimates of the proportion, and according to the power and electricity price calculation the internal rate of return of the project.
