The State Grid Corporation of China officially released the "Opinions on the Implementation of Distributed Photovoltaic Power Grid-connected Services" on the 26th, marking a significant step forward for the renewable energy sector. Following this, provinces under the State Grid have rolled out detailed guidelines to support grid connection for distributed photovoltaic systems. Among the various technologies, micro-inverters have gained popularity among PV module manufacturers and EPC companies due to their multiple benefits, including efficient power generation, long service life, and ease of installation and maintenance.
At APS's domestic sales headquarters in Shanghai, inquiries about mini-inverter products have been increasing rapidly. The sales team reported that calls are coming in non-stop, and the regional sales manager shared: "Previously, we spent a lot of time explaining the advantages of micro-inverters, and customers did understand them. However, they often hesitated due to policy uncertainties. Now, with clearer national policies in place, more customers are reaching out proactively. Even some companies are willing to pay cash upfront for these solutions. It's a real shift in the market."
With the latest policy on distributed power generation, Shanghai Power has started accepting applications for small-scale solar projects. Many forward-thinking homeowners are already planning to install 1 kW systems on their rooftops. According to Luneng Solar’s sales manager, a 1 kW system can generate approximately 21,900 kWh over its 20-year lifespan. With the government purchasing electricity at 1 yuan per kWh, the total revenue would be around 21,900 yuan. The initial investment for a 1.5 kW system is about 9,000 yuan, resulting in an estimated profit of 12,900 yuan.
Sunergy PV representatives noted that recent market trends show increased interest from real estate developers entering the micro-inverter space. These companies often require large-scale installations, which is a new phenomenon. Previously, such demand was rare, and many systems remained unconnected to the grid. As awareness grows, the residential market is unlocking a huge potential for micro-inverter adoption, signaling the start of a broader industry transformation.
Compared to centralized inverters, many domestic users have realized that these traditional options are not ideal for distributed solar projects. Issues like low efficiency, short lifespan, and difficult maintenance significantly impact system stability and investor returns. As a result, there's a growing shift toward micro-inverters.
Industry analysts report that some EPCs in Jiangsu once relied heavily on centralized inverters, but now investors are opting for micro-inverter retrofits. This trend highlights the changing landscape of the solar market.
In the challenging years of the PV industry, component manufacturers and EPCs have faced numerous obstacles. However, micro-inverters could offer a new opportunity for recovery and growth. The era of neglecting performance, lifespan, and price wars may finally be ending. For the photovoltaic industry, this marks a promising new chapter. Shanneng Solar will continue to contribute to the advancement of China's distributed solar technology and market development.Wuxi Ding Guohua Hand drawn Wallpaper Co., Ltd , https://www.silkwallpaperasia.com
