Recently, according to statistics from a professional photovoltaic market research organization, the existing intentions, contracts, and photovoltaic projects under development that have been disclosed in China have reached 130 GW, which is even higher than the national newly drafted “twelve- The five goals are more than three times as many. As the photovoltaic industry's external environment and internal photovoltaic policies become increasingly clear, the domestic photovoltaic application market is about to usher in a new round of construction boom.
According to theoretical calculations, various factors such as lighting resources, convenient conditions for grid connection, and the average income level within 25 years of stable operation of the power plant are taken into consideration. Taking the western photovoltaic power station as an example, the return on investment can reach 8%. -12%, so calculated, investing in photovoltaic power plants can indeed ensure stable returns. However, these preconditions, combined with the current status of the domestic photovoltaic industry, are not easy to achieve.
Reason 1: Investment Cost Affects the Investment Income of the Power Plant
At present, a considerable part of the power station investment capital comes from companies in various industries in which the demand shifts. The purpose of the investment is not to hold the operating power station for a long period of time to gain profits. The original intention is to digest the long-overdue inventory of battery components. Second, It is hoped that the power station will be transferred to operators after the completion of the power station to obtain additional income. At present, a large-scale photovoltaic power station is built in the northwest, and the comprehensive cost unit price is about 8 yuan/watt. The power stations built before 2012 are basically all at 9 yuan/watt or more, or even 12 yuan/watt, in order to reduce the investment cost and the component materials. Shrinkage is a major cause of the serious decline in the photovoltaic conversion rate of PV power plants, which greatly reduces the investment income of the power plant and even causes losses. Studies have shown that for every 1% increase in the photoelectric conversion efficiency, the cost can be reduced by 5%. Similarly, for every one year of extension of the photovoltaic power plant, the return to the developer is even more abundant.
Reason 2: Construction Quality Affects Investment Income of Power Plants
From the relevant data, the quality of photovoltaic power stations partially completed construction is slightly more problematic. According to the reporter's understanding, the existence of some power plant construction quality is not unrelated to the sudden introduction of relevant national policies. In 2011, the state issued a large-scale photovoltaic ground power station 9.30 deadline subsidy standards and policies, resulting in many power station construction companies hastily launched the photovoltaic power station project. In the rush to install the boom, a large number of uneven engineering services providers involved, when the quality of power station construction can not be guaranteed. Once upon a time, the difficulty in grid connection and difficulty in subsidy were the major problems that have plagued power plant developers. Under the active cooperation of the power grid, after the Ministry of Finance cleared the arrears of subsidy, it has been effectively resolved, and “get money and go online.†Photovoltaic power plant developers have fallen into the ramp of their own construction. The quality of photovoltaic power plants that have just been operating is in frequent occurrence. Some photovoltaic power plants built for only two years have been damaged due to design and construction defects such as the yellowing of photovoltaic modules and cables. Short-circuit-induced power plant fires, array foundations, and bracket accidents are also commonplace in PV power plants. If you only see the interests of the time and sacrifice the long-term benefits of the future, it may not be a wise choice. It may jeopardize the quality and service life of the entire system, and it is also an unfair practice for the entire investment.
In fact, the service life of photovoltaic modules is usually at least 25 years. It is not surprising that PV power plants in foreign countries continue to generate electricity for 40 years.
Improve the quality of construction and rationally reduce costs to ensure the return on investment
Fortunately, the pursuit of quality is being accepted by domestic power station developers. Compared with the past, the quality requirements for the developers of photovoltaic power station construction have been significantly improved. Many power station developers have realized that the extension of the investment return period of the entire power station and the stability of power generation efficiency are the two most critical aspects of ensuring the benefits of power plants. In the newly-built photovoltaic power station project, many developers began to actively seek cooperation with Norseman Energy and Hao Sheng as a brand service provider and ensured the operation cycle of the photovoltaic power plant with its excellent construction quality, thereby reducing the cost of electricity generation and increasing The effect of investment returns is more obvious, and the extension of the life of the power station will give investors a greater return on investment. ""
It is the entire photovoltaic industry that will not hesitate to reduce the cost of quality, reasonably reduce the investment cost, and ensure that the quality of power station construction is the basis for the sustainable and healthy development of the photovoltaic industry, and improving the quality of photovoltaic power station construction has become a top priority. Adhering to the long-term power generation benefits brought by high quality and high performance will become the core of the development of the photovoltaic industry.
