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 solar energy sector. Following this, provinces under the State Grid have started to roll out specific guidelines for grid connection, signaling a more structured and supportive environment for distributed photovoltaic systems.
Micro-inverters are gaining popularity among PV module manufacturers and EPC companies due to their numerous advantages, including multiple power generation points, longer lifespan, and easier installation and maintenance. These features make them particularly suitable for small-scale and residential applications.
At APS's domestic sales headquarters in Shanghai, inquiries about mini-inverter products have been overwhelming. According to the regional sales manager, “In the past, we had to spend a lot of time explaining the benefits of micro-inverters, and although customers understood them, they were often discouraged by policy uncertainties. Now, with clearer national policies, more customers are proactively reaching out to learn about our products. Some even prefer to pay upfront for early adoption.â€
Thanks to the latest distributed power generation policy, Shanghai Power has begun accepting distributed photovoltaic systems for grid connection. Many environmentally conscious users are already preparing to install 1 kW systems on their rooftops. Luneng Solar’s sales manager provided a detailed calculation: a 1 kW system is expected to generate around 21,900 kWh over its 20-year lifespan. With a purchase price of 1 yuan per kWh, the total revenue would be approximately 21,900 yuan, while the initial setup cost for a 1.5 kW system is around 9,000 yuan. This means a potential profit of 12,900 yuan for the customer.
According to Sunergy PV sales personnel, “Real estate developers are now entering the micro-inverter market, driven by large-scale demand. This is something we haven’t seen before—many projects were previously not connected to the grid. The consumer market holds a lot of untapped potential, and it seems the era of widespread micro-inverter use is just beginning.â€
Compared to centralized inverters, many domestic customers have realized that these systems are not well-suited for distributed generation and grid-connected projects. They often suffer from low efficiency, short lifespan, and complicated maintenance, which can negatively impact system stability and investor returns.
A market analyst from an industry media noted, “EPCs in Jiangsu previously relied on centralized inverters, but some investors have started retrofitting existing systems with micro-inverters to improve performance.â€
During the tough times of the PV industry, component manufacturers and EPCs have faced challenges, much like the mythical Phoenix rising from ashes. Micro-inverters may offer a new opportunity for the industry to renew itself. The era of neglecting energy output, ignoring system lifespan, and engaging in price wars may finally be coming to an end. This is a positive development for the entire solar industry. Shanneng Solar will continue to contribute to the advancement of China’s distributed photovoltaic technology and market growth.Wuxi Ding Guohua Hand drawn Wallpaper Co., Ltd , https://www.silkwallpaperasia.com
