Photovoltaic power stations welcome micro-explosive growth

State Grid Corporation of China officially issued the "Opinions on the Implementation of Distributed Photovoltaic Power Grid-connected Services" on the 26th, and the provinces covered by the State Grid have also introduced detailed specifications for the grid connection. Micro-inverters are favored by PV module manufacturers and EPC manufacturers due to their advantages such as multiple power generation, long design life, and easy installation and maintenance.

In APS's domestic sales headquarters-Shanghai office, the customer consulted with the mini-inverter products, the telephone was in an endless stream, and the head in charge of the regional sales stated: "In the past, most of the customers spent a long time to explain the advantages of micro-reversal, and the customers also recognized it. The many benefits of micro reverse, but the final customers are repulsed due to policies and other factors.With the continuous introduction of national policies, now take the initiative to call to understand the company, individual users of micro reverse, more and more, and even some companies to pay cash Pick up."

Due to the release of the latest distributed power generation policy, Shanghai Power has begun to accept distributed photovoltaic power generation on-grid. At present, ordinary users with advanced awareness are already preparing to install a 1 KW system on their home roofs. Luneng Solar's sales manager calculated a bill for the customer. According to the calculation of 1 kWh of electricity, the system is conservatively estimated to send 21900 kWh of electricity within 20 years of its service life. At present, under the relevant national policies, unified purchase and sales are implemented, and the electric power company purchases at 1 yuan/kWh, for a total of 21,900 yuan, while the one-time input cost when setting up the 1.5kW system is 9,000 yuan. The estimated revenue of the customer can reach 12,900 yuan. With regard to the recent market conditions, Sunergy PV sales personnel stated: “Recently some real estate developers have also begun to set foot in the micro-reversal market, and the demand is usually relatively large. There has never been such a situation before, and it may not have been connected to the grid before. The civilian market has saved a lot of potential purchasing power, and the era of micro-reverse in the country is really about to begin large-scale use."

Referring to centralized inverters, many domestic customers have already realized that “centralized inverters have no advantage in distributed generation and grid connection projects, and they have disadvantages such as low power generation, short life, and inconvenient maintenance. Seriously affect the stability of the system, causing the loss of the investor's profits."

A market analyst of an industry media mentioned that “EPCs in Jiangsu Province had previously used centralized inverters. Recently, some investors have used centralized inverters to build systems before using micro-retrofitting.”

In the difficult years of the PV industry, component factories and EPC companies will be like Phoenix Nirvana. Perhaps micro-inverters will give the industry a chance to regenerate. The era of ignoring the generation of electricity, the life of the power plant, and the low price of hostile competition may be gone forever. This is a great fortune for the photovoltaic industry. Shanneng Solar will also continue to make its own contribution to the development of China's distributed photovoltaic power generation technology and market development.
