Image
At 21:59 on November 30, 2025, with a clear command from shift supervisor Liu Jiahao, the Wuhai 200,000 kW/800,000 kW semi-solid-state energy storage power station—China's largest grid-side independent new energy storage project using semi-solid-state lithium iron phosphate batteries—successfully connected to the grid. Invested and constructed by China Green Development Investment Group Co., Ltd., the project covers approximately 100 acres and has a total investment of 600 million yuan. It is the first large-scale energy storage project in Inner Mongolia Autonomous Region to adopt semi-solid-state lithium iron phosphate battery technology. This "super power bank" features 160 energy storage battery compartments and 40 integrated converter and booster compartments. Through peak-shaving regulation, it can deliver 189 million kilowatt-hours of clean electricity to the grid annually. Based on typical household electricity standards, a single maximum discharge of 800,000 kilow...

Reliability and Economic Analysis of Photovoltaic Power Plant Product Selection

Image
  With the accelerated global energy transition, the photovoltaic industry has become a crucial pillar of renewable energy development. In recent years, global photovoltaic installed capacity has increased by as much as 85% year-on-year, with China accounting for more than 60% of the global new installed capacity, highlighting its leading market position. Against this backdrop, the selection of photovoltaic power plant products, including photovoltaic modules,   inverters , mounting systems, and auxiliary equipment, directly affects the power generation efficiency, operational reliability, and overall life-cycle economic benefits of the power plant. A scientific selection strategy needs to comprehensively consider initial investment, operation and maintenance costs, and long-term returns, taking into account the specific climate, terrain, and policy constraints of the scenario, and choosing the solution with high technical adaptability and the optimal cost per kilowatt-hour. 1...

How do photovoltaic (PV) inverters achieve active and reactive power regulation?

Image
  With the development of the PV industry, the ability of inverters to accept grid dispatch has increasingly become a key feature for PV equipment manufacturers and users. String inverters offer flexible active and reactive power regulation capabilities, with an active load rate settable from 0% to 100%, and selectable active power overload output capacity of 1.1 times. In capacitive or inductive states, the maximum reactive load rate can reach 70% P-apparent, and the power factor can be set from 0.8 leading to 0.8 lagging. They also feature multiple reactive power modes to adapt to the needs of different power plants. They can accept and fully comply with dispatch instructions from the grid to fully meet grid access and control requirements. Inverters achieve independent or coordinated regulation of active and reactive power through control strategies and hardware topology, specifically as follows: 1. Active Power Regulation Active Load Rate Mode The corresponding equipment can re...

Perovskite Photovoltaic Equipment: The Dawn of Commercialization Has Appeared, but Key Hurdles Remain for Full Market Launch

Image
  Perovskite photovoltaic technology, with its astonishing development speed and disruptive potential, is hailed as the "rising star" of the photovoltaic industry. Its core advantages lie in: Ultra-high theoretical efficiency: Single-junction theoretical efficiency exceeds 30%, and tandem structures break through 45%, far surpassing crystalline silicon cells. Low cost and simple process: Low material cost, allowing for solution-based preparation (such as coating and printing), with energy consumption far lower than the high-temperature process of crystalline silicon. Lightweight, flexible, and application expansion: Can be manufactured into lightweight, thin, flexible, and semi-transparent modules for new applications such as building-integrated photovoltaics (BIPV), wearable devices, and car roofs. 1. Industrialization Process Currently, perovskite photovoltaics has moved beyond pure laboratory research and entered an exciting pre-industrialization stage: Efficiency records ...

A novel perovskite photovoltaic device achieves a photoelectric conversion efficiency of 25.19%

Image
A research team from Nanjing University of Technology has made a breakthrough in the field of perovskite photovoltaic technology. Using a unique "full-vacuum thermal evaporation" technique, the team successfully fabricated a perovskite photovoltaic device with an area of 0.066 square centimeters, achieving a photoelectric conversion efficiency of 25.19%, once again breaking the world record for this technology. This achievement was officially published in the internationally renowned journal *Nature Photonics* on October 21, 2025. The core of this breakthrough lies in the comprehensive optimization of the "full-vacuum thermal evaporation" technique. According to Guo Qingxun, the corresponding author of the paper and an associate professor at Nanjing University of Technology, this technology is similar to "evaporating" thin films in a vacuum environment: the raw materials are heated, causing them to vaporize in molecular or atomic form and deposited on a su...

Tesla's Shanghai Gigafactory's roof is now fully covered with solar panels, generating 11 million kilowatt-hours of electricity annually
