"Energy storage" has become a crucial breakthrough point in the transformation of the photovoltaic industry



"God closes a door to you, and then opens a window to you." This sentence can not be more suitable to describe the current photovoltaic market. When the photovoltaic industry is in urgent need of transformation, energy storage has become a crucial breakthrough point.

"God closes a door to you, and then opens a window to you." This sentence can not be more suitable to describe the current photovoltaic market. When the photovoltaic industry is in urgent need of transformation, energy storage has become a crucial breakthrough point.

When photovoltaics were in full swing in China, we knew that the existence and development of photovoltaics has been recognized and accepted by people. Even ordinary households have already appeared in photovoltaics. People who installed photovoltaics have reversed every month. The situation where electricity bills must be paid to the State Power Company. You can generate electricity for your own use, and you can also be a "little businessman" who sells electricity legally. Life has gradually become better, but what kind of sparks can be sparked when photovoltaic meets energy storage?

Recently, research results show that, regardless of the national policy environment or the growth trend of energy storage projects at home and abroad, in the eighth year of steady progress in energy storage, commercial operation has become clear, and the energy storage market has released positive signals. The industry generally believes that 2018 may become the starting point for the commercial application of energy storage.

1. Jiangsu Province encourages the development of energy storage

If the "5.31" photovoltaic new policy is to some extent, like a sap on ambitious photovoltaic people who are ready to go on a big fight, so that some photovoltaic practitioners will start to retire, then the Jiangsu Provincial Development and Reform Commission recently issued The "Guiding Opinions on Promoting the Development of Distributed Energy Microgrids" is more like a beacon, allowing photovoltaic people who suddenly fell into confusion to discover the direction to go forward, pack lightly, and once again explore a new path for photovoltaic applications. Compared with our photovoltaic capacity, the scale of energy storage projects in Jiangsu Province cannot consume our excess capacity. However, the development path of energy storage is indeed necessary, and it is also the direction of the development of photovoltaic applications.

2. Energy storage = self-salvation of the photovoltaic industry?

"5.31" brings the pain of photovoltaic people to the skin, cannot rely on subsidies to develop, must throw away the crutches of subsidies, independent development; and energy storage happens to give photovoltaic independent development opportunities.

The domestic photovoltaic industry is now facing an increasing gap in state subsidies, and the subsidies have been delayed in disbursement, and the photovoltaic production capacity is increasing.

In the case of increased expansion and nowhere to absorb the produced photovoltaic products, energy storage may be a good medicine to cure the current symptoms. Although this straw currently seems to have disadvantages such as high price, large one-time investment, and the complexity of the entire system, it is a viable development direction for the photovoltaic industry.

Because it solves the shortcomings of photovoltaic, wind energy and other electricity instability and difficulty in storage. At the same time, it has applications such as peak shaving and valley filling, auxiliary new energy grid connection, and grid frequency modulation. Develop energy storage, throw away the crutches of subsidies, rely on your own business model to make profits, and promote the healthy development of the industry. This is probably the road to photovoltaic development.

Three, photovoltaic + energy storage may become a life-saving straw

When it comes to energy storage, people often associate it with batteries, but they don’t know that the photovoltaic + energy storage mode is more promising under the influence of the 5.31 New Deal. The perfect combination of the two can obtain further advantages, especially in the era of subsidy decline. Only by fully considering the specific circumstances and constructing a business model can sustainable profitability be achieved.

With the increasing proportion of photovoltaic installed capacity in energy supply, the disadvantages of photovoltaic power generation relying on weather and unstable output power have gradually become prominent. Photovoltaic + energy storage can achieve peak shaving and valley filling, matching the power load on the power generation side and the power consumption side. , Greatly reducing the impact of photovoltaic power generation on the grid, and will make a great contribution to the establishment of a reliable, flexible and economical low-carbon grid in the future.

From the application side, the benefits of photovoltaic + energy storage for users are also very intuitive, which can maximize the benefits of photovoltaic power generation. Switching, the direct income of the owner will increase by more than 15% compared with the conventional grid-connected photovoltaic system.

4. Multi-provincial expansion of energy storage market outlets

At present, the energy storage industry covers almost all provinces in the country. Among them, Jiangsu, Tibet, Shanxi, Gansu, Qinghai, Beijing, Guangdong, Shanghai and other provinces and regions have the largest scale of new operations. The energy storage market is very active and has its own characteristics. .

According to CNESA's incomplete statistics, as of the end of 2017, the cumulative installed capacity of China's operational energy storage projects was 28.9GW, a year-on-year increase of 19%. The cumulative installed capacity of electrochemical energy storage was 389.8MW, a year-on-year increase of 45%, accounting for 1.3% of the total installed capacity, an increase of 0.2% over the previous year. The electrochemical energy storage project planned in the first quarter of 2018 is close to 120MW.

5. Foreign energy storage is also developing rapidly

For example, in the past three quarters in California, the proportion of solar energy customers adopting energy storage in California has approximately doubled every quarter. According to GTMResearch's forecast, the deployment of the U.S. home energy storage market this year may quadruple from last year.

Due to the rapid development of distributed energy in California, there has been a "California duck" phenomenon. With the addition of an energy storage system, peak shaving and valley filling can be achieved, and the problem of power grid capacity reduction can be alleviated.

Six, the imagination of energy storage is huge

In the past two days, the editor posted a home energy storage project in Zhengzhou, Henan in the circle of friends. More than a dozen people and friends privately wrote to the editor to learn about the project's situation and development prospects. All have shown great interest in the development of energy storage. Under this trend, it is up to who can seize the new opportunities.

Due to high household electricity prices in Europe and Australia, energy storage products have begun to enter thousands of households. This situation is like photovoltaics ten years ago, with long-term layout of energy storage application products.

Electric vehicles and new energy vehicles have allowed energy storage to appear around us, but there is still a certain distance to apply to each of our households. The blank indicates that this market is still vacant, and the future development space is huge. This will not be too long. Just in the past two years, the energy management we imagined will become a reality.

Just as we are complaining about the failure of the photovoltaic industry, some people have already got on the fast train of energy storage. Policies and opportunities wait for no one. Come and develop energy storage application products.

Nowadays, energy storage technology is the direction everyone is working together, and subsidies for energy storage batteries have been introduced. Because of the emergence of energy storage subsidies, some experts predict the explosion of energy storage or in 2019, regardless of whether energy storage will be in In 2019, what is certain is that energy storage must be the future development direction. By then, the maximum use of photovoltaic energy will be realized, so that clean energy will shine!
