In response to the impact of the “two-way” between europe and the united states on our photovoltaic manufacturing industry, since the second half of last year, a series of policy initiatives have been intensely introduced by the national authorities that have been hailed by industry as the “pvp” in an attempt to change the over-reliance of the photovoltaic manufacturing industry on exports by accelerating the launch of a market for domestic photovoltaic applications. What are the changes in the development patterns of the domestic photovoltaic industry as a result of these policies? Is the "spring" really here in the photovoltaic industry? How far do we have to go from the power of photovoltaic to the power of photovoltaic applications
Income and expenditure of the “first person selling electricity” at the household photovoltaic station
"before the bright light voltage on the roof, it will be known that it is chu's home." there are few people who do not recognize zhu qiji in the town of ting ding, jiangdu district, jiangsuyan state. Last june, zhu quijie invested $50,000 to build a five kilowatt distributed roof power station on his roof, thus becoming the “first crab eater” in the jiangsu distributed photovoltaic field and the “first to sell” electricity to his family。
Since 2013, distributed photovoltaic power has shown a rapid expansion in the country as many of the obstacles to the construction of distributed photovoltaic plants are being removed. Family pv stations have come closer to ordinary people's lives。
More than a year has passed. How is zhu kaiji's personal home photovoltaic power station running? “a system of 5 kilowatts, which generates more than 20 degrees in the clear sky and about half of the sunny weather, has produced a total of approximately 6,000 degrees a year due to a failure of two months in the middle.” zhu kaiji said that the net gain for a year was only 4,000。
Zhu kaijie calculates the proceeds for “china net” journalists: according to local policy, distributional photovoltaic plants receive a tax subsidy of $0. 359 for every single degree of electricity, whether for their own use or sold online. This amount is subsidized for a total of $$2154; electricity is sold to the national grid, with an additional $0. 3675 for each degree, and 5,400 for a total of $1984. 5 a year. In addition, his family used 600 degrees of electricity a year, resulting in savings of $316. 98 at a cost of $0. 5283 per degree。
According to zhu quijie, in this calculation, the investment in the home pv plant could be recovered for about 11 years, based on the 25-year lifetime of the plant and at least 14 years of net return。
Distributional photovoltaic or rapidly expanding “golden period”
In 2013, we issued a number of observations on the promotion of the healthy development of the photovoltaic industry, proposing to expand the market for distributed photovoltaics and to support the promotion of small distributed photovoltaics in schools, hospitals, party bodies, businesses and community buildings。
The distribution of photovoltaic power stations, driven by pro bono policies and represented by household roof-voltage, government public institutions, and industrial parks, has grown rapidly over the past year。
In the second half of last year, jiangxi province began the construction of a “model project for a 10,000 roof-voltage photovoltaic power plant”, which will open all distributional photovoltaic power stations in 11 established municipalities, with nearly 2,000 households applying for installation in that year. As of the first half of this year, the national grid, jiangsu, has received more than 600 distributed photovoltaic power projects, 391 of which have a power capacity of 2161. 52 kilowatts。
According to data released by the national energy agency in early august, in the first half of this year alone, new distributed photovoltaic grid capacity reached 990,000 kilowatts (kw) across the country, exceeding the new distributed photovoltaic grid capacity in 2013。
“distributed photovoltaic power is expected to be the area with the greatest potential and the fastest growth in our photovoltaic market in the coming years.” the officer-in-charge of the ppv professional committee of the china renewable energy society said that, as the new energy policy environment became more and more relaxed, the rate of construction of distributed photovoltaic plants increased markedly。
In the view of industry, the distributional photovoltaic market will continue to heat up and develop a “gold season”, driven by sound policy factors, in keeping with the principle of development that focuses on distributional photovoltaics, in parallel with distribution。
“distributive photovoltaics, which encourage spontaneous and in situ absorption, can reduce shocks to the electricity grid, while many areas are characterized by heavy haze, thirst for clean energy, and prospects for new photovoltaic energy industries.” a career manager in the field of light energy, yu yongwen。
Universalization of distributed photovoltaics requires a three-track solution
“china net” journalists have learned that, with subsidies, settlements, approvals and internet access barriers removed, the investment in distributed photovoltaic plants has been unprecedented, but that financing difficulties, poor business models and poor quality security have become the “tricans” that plague their development。
Industry sources indicate that the initial phase of distributed photovoltaic projects is characterized by high investment and long return cycles, and that banks and financial institutions are less motivated to lend to distributed photovoltaic projects for risk reasons, which makes financing difficult。
“in wind energy development, the state has preferential interest rates, but there is a lack of clarity in the policy on photovoltaic power generation. On the contrary, private enterprises like us may have higher interest rates on bank loans.” the distributive pv investor qiang said that, when applying for bank loans, pv enterprises were required to provide additional equivalent guarantees for loan amounts in addition to preparing capital funds, which was a challenge for investors in family pv plants。
At the same time, the problem of roofing is highlighted by the incomplete commercial model of distributed photovoltaic power。
“most of our cities are high-rise buildings, roof power is linked to the ownership of roofs, and the entire business model is worth further exploring. Wang shijiang, an expert in the china guangvo industries union, said。
According to hu yong, chairman of twilight, roof resources are now becoming scarce, while companies with large roofs and individuals are not necessarily interested in photovoltaic power. Some would be willing to rent the roof, but would “knock it off” and, for some reason, might also change their minds, which would put investment at great risk。
“the mature business model that we understand is that all people, whether consumers or producers of electricity, as well as governments, banks, investors, owners, etc., must be profitable in order to be sustainable.” hu yong says。
In addition, the poor quality of distributed photovoltaic plants is an important factor influencing investment incentives. It is understood that the internal rate of return for distributed photovoltaic plants can reach 8-10 per cent under the current price of photovoltaic components and the state subsidy policy, but this rate of return is achieved on the basis of 20 years of stable operation of the power station. At present, the quality of our pv plants and the quality of after-sales services do not allow investors to develop stable returns。
The industry believes that, in order to accelerate the launch of the domestic market for distributed photovoltaic applications, there is an urgent need to improve technical standards for the construction of photovoltaic products and photovoltaic plants and to establish and improve quality monitoring systems for the construction of distributed photovoltaic plants。
