Home PV power station: It takes ten years to invest 25,000

Mr. Fang, a resident of Songjiang Jiuting, became the “crab-eater” of Shanghai's distributed power grid. He also launched the distributed photovoltaic power generation support policy of the State Grid Corporation last year. The State Grid recently released “Distributed Power Supply”. After the opinions of the grid-connected service work (hereinafter referred to as the "Opinions"), Shanghai's first grid-connected users.

Although residential PV power generation can be sold to the country after a series of policy support, the reporter recently experienced this “small power station” in Mr. Party’s home and found that the speed of the distributed power project was not as fast as the industry expected. . Promotion in residential areas will be limited by many factors such as venues and costs. At the same time, before the NDRC finally determines the price of electricity purchased online, there are still uncertain factors in the launch of the PV market.

Difficult to promote residential areas

On the afternoon of March 15, when the reporter arrived at the party's home, the newly-built "small power station" in January this year had already generated 10.15 degrees. In February, in the case of severe shortage of sunshine in Shanghai, the monthly power generation of Mr. Party’s family was 136.57 degrees, of which 105.38 degrees was online and 31.15 degrees was used by himself, but Mr. Party’s family used 380 degrees.

In March, as the weather improved, as of the reporter's interview, Mr. Party's family generated a total of 124.33 degrees of electricity. Last year, Mr. Party's average household electricity consumption was 300 degrees per month. The “power station” could not achieve self-sufficiency. This is related to the photovoltaic power installed by Mr. Party. Due to the limitation of the roof area, it only installed 10 sets of plates with a total power of 3 kW.

For electricity that has already been connected to the Internet, Beijing and other places are acquired at a price of 0.4 yuan/kWh of desulfurized coal on-grid. At present, the policy implemented by Shanghai Power Grid Corporation is to “install a meter with two-way metering function for photovoltaic power generation users to ensure the accuracy of the user's self-generating readings and normal power readings, and to make settlement subsidies after the NDRC policy is issued.”

According to the statistics of Shanghai Electric Power Company, after the introduction of the national policy in November last year, Shanghai Electric Power Company began to accept the application of distributed power supply. Up to now, 20 users in Shanghai have submitted applications, including 6 households and enterprise users. 14 households, distributed photovoltaic equipment of residential users have all been connected to the grid.

"From the current situation of users who have applied for it, most of the employees in the photovoltaic industry and environmental protection enthusiasts, including the enterprises that are applying for are also the photovoltaic enterprises themselves or related industries." Shanghai grid company related person said.

Mr. Party told reporters as an insider. "At present, PV companies are not open to individual users. For production companies, large orders are required. One or two pieces of solar panel components are not sold at all. The retail channels open to ordinary residents are only online shopping. Some of the traders' second-hand or export-to-domestic PV modules will be sold online, or even in the form of 'packages', but not including installation.

“Because installation involves many specific problems, it is easy to cause disputes in neighborhoods and properties. No one is willing to take this responsibility.” Mr. Party said that it costs about 25,000 yuan to purchase equipment and installation, and there are certain technical standards for the installation of components. For example, the load-bearing of the roof, the thickness of the cement board of the fixed components, the angle of the bracket slope, etc., and there is currently no special installation company to do this. The country has not issued relevant technical and qualification standards for the residents themselves. The technical specifications for purchased component equipment are currently unclear.

The Shanghai Electric Power Company quoted a professor from the School of Electric Power as saying that “photovoltaic power generation systems are more suitable for independent or semi-independent villas, remote suburban government agencies and some university enterprise demonstration parks. These places can be based on new energy generation and traditional energy as backup.”

A person from the Jiangsu Photovoltaic Industry Association also said that "the future market for distributed power projects will still be dominated by rural and urban villas."

Long return on investment

According to the "Opinions" promulgated by the State Grid Corporation of China, the State Grid will provide access system planning, grid-connected testing, commissioning and other full-process services for distributed photovoltaic power generation projects within the applicable scope, without charging fees. At present, distributed photovoltaic power generation in China mainly refers to rooftop power generation, while the large-scale roof resources are mainly industrial production enterprises in shopping malls and development zones. Therefore, distributed photovoltaic power plants are mostly private. The cost of distributed generation will be higher than that of large-scale photovoltaic power plants on the ground, because it involves roof renovation, smaller inverters, and more support.

Although Shanghai Power Grid Corporation views distributed photovoltaic power generation with “support, welcome, and service”, it also said that “the investment return period is long, the cost of photovoltaic power generation equipment is too high, the licensing of photovoltaic equipment in public areas, and the national price subsidy. The policy is not clear enough, etc. is the biggest dilemma of distributed photovoltaics."

According to the guidance of the State Grid Corporation, the Shanghai Grid Corporation is fully free of charge to the grid-connected users. This involves the annual budget and the annual budget, which makes the Shanghai Grid Corporation extremely difficult. "We expect that the capacity of Shanghai's distributed power projects will be around 500,000 kilowatts in the next few years. However, this data does not have corresponding support. The scale of development depends on the cost of photovoltaic panels and the strength of the state's support for new energy policies. It is difficult to make an accurate prediction at present." The relevant personage of the above-mentioned Shanghai Power Grid Company said.

Take Mr. Party’s family as an example, with a total investment of 25,000 yuan. It is estimated that if the grid company recovers at a price of 1 yuan/kWh, it will take about 10 years to recover the cost. This does not include the maintenance costs that may occur in the equipment. .

In the interpretation of the State Grid, to get the feed-in tariff of 1 yuan / kWh, the power station must be approved by the National Development and Reform Commission. Whether it can reach 1 yuan / kWh is still unknown, but there is news from the NDRC meeting that the final recycling price may be 1 yuan / kWh.

The above-mentioned Jiangsu Photovoltaic Industry Association said that "the cost of photovoltaic power generation is around 1.2 yuan / kWh. If it is lower than this expectation, policy promotion will be limited."

In 2012, Jiangsu Province issued the “Implementation Measures for Implementing a New Round of Supporting Policies for Promoting Photovoltaic Power Generation”, which clarified that the on-grid price of photovoltaic power generation in Jiangsu is 1.3 yuan/kWh in 2012 and 1.25 yuan/kWh in 2013, 2014. It is 1.2 yuan / kWh, and in 2015 it was 1.15 yuan / kWh. Compared with the residents' electricity price of 0.6 yuan to 07 yuan / kWh (half price discount is half price), the industrial electricity price is 1 yuan / kWh, the purchase price of 1 yuan / kWh does not have an advantage, especially for residents In terms of.

Last year, the National Energy Administration raised the distributed generation plan from 10 GW to 15 GW within one month. It is hoped that under the US “double opposition” and European anti-dumping, the Chinese PV industry in the winter will receive more support from the state, but PV However, the market has not been warmed up due to the promotion and subsidy price issues. The market sales channels for individuals and small and medium-sized enterprises have not yet been established, and now they are staying at the experimental stage.

"We expect the price of the National Development and Reform Commission to be around 1.2 yuan / kWh. At the same time, we also hope that China's distributed power supply project should be like Germany, and the capacity should be released, so as to drive the development of the photovoltaic industry." Said.
