"The total installed capacity of my home's photovoltaic power station is 5 kilowatts, and now we generate more than 30 degrees of electricity every day. If we count the policy subsidies, we can earn about 1,000 yuan per month." Through telephone, Zhang Aiguo told reporters with a simple set of data. His own "power station."
Zhang Aiguo, a villager in Dongyangzhuang Village, Kaiyuan Town, Dingzhou, Hebei, and a family photovoltaic user of Yingli Group. In September of last year, he invested 35,000 yuan to install solar panels on his home's bungalows, and was completed by Baoding Power Supply Company. The photovoltaic power station in his mouth belongs to home photovoltaic and is a subdivision of distributed photovoltaics.
Home photovoltaic, not only energy-saving and environmental protection, but also considerable profits, was vividly described as "roof bank." With the popularization of the concept of green development, new energy industries represented by home photovoltaics are ushering in opportunities for development.
Solar energy resources are everywhere, and building a small solar power station will become easier. In the near future, like Zhang Aiguo, perhaps each of us may become a beneficiary of photovoltaic power generation.
Blue Ocean Market
Considering environmental issues and other factors, the national level has paid more and more attention to the development of new energy sources such as photovoltaics.
According to the “13th Five-Year Plan for Electric Power Development,†the end of the “Thirteenth Five-Year Plan†is to achieve a target of more than 60GW of distributed photovoltaics, and a distributed installation of about 10 GW per year is required.
However, for many ordinary people, home photovoltaic is still a new thing. In general, home photovoltaic power generation systems include solar panels, inverters, combiner boxes, and brackets.
If the calculation is based on an average installation of 5 kilowatts per household, it will occupy an area of ​​about 40-50 square meters, with an initial investment of about 40,000 yuan and an average annual power generation of about 6,000 degrees. In addition to the electricity used by the household, the surplus electricity can be connected to the grid and sold to local power supply companies.
“Considering various factors such as lighting resources, local subsidies, product performance, and other factors throughout the country, this is usually returned in 5-8 years. The service life of the power station is generally about 25 years. After the cost recovery, electricity can be used for free, and electricity can also be sold. Power Supply Company.†When interviewed by the “Livelihood Weeklyâ€, Ying Zhen Group’s director of public relations Zhen Zhen said.
In fact, China's distributed photovoltaic market is really starting at the end of 2012 and early 2013—after grid companies have opened distributed power grid-connected services.
The prospect of family photovoltaics is favored by all parties and is still a blue ocean market. “According to estimates, there are more than 40 million independent rooftops in the country. If 20% of the roofs are covered with solar panels, the market size of home photovoltaics will be 320 billion yuan.†In an interview with the “Livelihood Weekly†reporter, Zhong Min Shin Kong Co., Ltd. executive vice president Bao Yudong said.
However, due to different support efforts, the development of home photovoltaics in various regions is not balanced. “In order to accelerate the speed of distributed power grid connection, Baoding of the State Grid Corporation has opened up a 'green channel'. As of the end of May 2017, the distributed power supply in Baoding area will be connected to 12198 households with a grid-connected capacity of 160,000 kilowatts.†Accepted by the “Livelihood Weekly†reporter During the interview, Huo Shengli, head of the marketing department of Baoding Power Supply Company, said.
“Each place has different policies and financial support for family photovoltaics, and the support of provinces such as Jiangsu, Zhejiang, Anhui, Shandong, and Hebei is relatively large and development is relatively good.†Interview with “Livelihood Weekly†reporter, PV Billion founder Liu Wei said.
Constraints
In reviewing the past few years, although all parties are optimistic, due to various reasons such as grid connection, rooftop property rights, subsidy policies, and public acceptance, China's distributed photovoltaics have not experienced explosive growth.
As early as around 2013, Yingli began to develop the home photovoltaic market. “As early as in the distributed photovoltaic industry, the initial stage of distributed photovoltaics was mainly large-scale ground power stations. At that time, the public was still relatively unfamiliar with home photovoltaics, and it took time for the public to recognize and accept home photovoltaics,†he said.
At present, distributed photovoltaics mainly rely on roof resources, but roofs face property rights issues.
In cities, rooftop property rights may become one of the major factors constraining the development of home photovoltaics. "If it is a multi-storey or high-rise building, the roof is collectively enjoyed by tenants, and installation of home photovoltaics will inevitably encounter property rights problems," said Liu Wei.
Rural home photovoltaic is mainly concentrated in self-built housing, and generally there is no problem of property rights. “The rural market accounts for a large proportion and is our main battlefield.†Bao Yudong said that the property rights of rural buildings are clear, and acceptance of photovoltaic products with clear and guaranteed revenues is high.
As an industry that is encouraged to develop, home PV enjoys multiple subsidies, including: State subsidies of 0.42 yuan/degree + local subsidies (different from different locations). It is understood that most of the provinces, cities, and counties that currently introduce local subsidies are concentrated in the eastern coastal areas.
However, according to Cai Guoxiong, deputy chief engineer of the China Electric Power Research Institute, the overall support for family photovoltaics is still insufficient.
“If you do not see a clear return, users are reluctant to make excessive investment at one time. This will require the government to reduce restrictions, increase incentives, and increase support.†Cai Fengxiong said when interviewed by the reporter of “Livelihood Weeklyâ€. .
The year of the outbreak
As a well-known company in the photovoltaic industry, Yingli attaches great importance to the family photovoltaic market.
“Yingli has opened the first photovoltaic experience shop in China. In 2014, it played the slogan of 'China Yingli Photovoltaic' at the World Cup in Brazil. In addition, Yingli also proposed the first full-process inspection standard in the family photovoltaic industry and the first after-sales service in the industry. Service standards."
Distributed photovoltaics are seen as a new force to lead the rapid growth of China's photovoltaic industry. In fact, as the market has grown, more and more companies are starting to pick up this market.
“In 2016, the installed capacity of household photovoltaics in Zhejiang Province was 30,000, and it is estimated that 150,000 households will grow in 2017. The market has grown four-fold; at the same time, in 2016, Zhejiang Province has 200 installers and service providers of household photovoltaics. This year, there are nearly 2,000 homes, and the number of companies has increased by 9 times, said Bao Yudong.
According to Bao Yudong, the increase in the number of users and participating companies is enough to prove the industry's vitality. His Zhongmin Xinguang Co., Ltd. has also recently released a “China Mind Intelligence†platform, which is known as the first domestic photovoltaic industry-wide interactive service platform for the industry to solve common pain points in the industry.
Many people in the industry believe that in 2017, the home photovoltaic market may usher in an outbreak.
After years of development, the cost of home photovoltaic power generation equipment has dropped significantly, and it is possible to implement large-scale promotion. For example, the production costs of silicon, ingots, wafers, batteries, and components required for home photovoltaics have all fallen dramatically.
“This year is not only the year of the outbreak of the home photovoltaic market, but also the first year of the application of photovoltaics to a wider area.†Yu Zhen said that after more than 20 years of development, the photovoltaic industry has formed a mature product and a track record of technology upgrades. The path, and more importantly, the concept of “low-carbon, environmentally-friendly, and profitable†photovoltaics for homes is well-known.
