More and more people are building home-based distributed photovoltaic power stations, but the amount of electricity generated varies even with the same installed capacity. So how can you effectively increase the power generation of your rooftop solar system?   First, let's look at the factors that affect solar power generation. 1. Sunlight conditions: Home solar power stations utilize solar energy for power generation. The better the natural light resources, the greater the power generation. In areas with similar sunlight conditions, power stations installed at the optimal tilt angle after preliminary measurement and design will generate significantly more electricity than those installed without such preliminary measurement and design.   2. Product quality: ① Photovoltaic module quality. High-quality photovoltaic modules with high conversion efficiency will naturally generate more electricity. ② Inverter quality. High-quality inverters have high conversion efficiency, resulting in higher power output.   3. Installation quality: Professional and reliable installation services ensure that the modules are installed at the optimal tilt angle, preventing damage to product components and avoiding potential construction hazards, thus preventing subsequent safety issues such as leakage, fire, and lightning strikes. Unprofessional installation may damage product components and even lead to safety problems.   4. Daily operation and maintenance: Dust and obstructions can affect the conversion efficiency of photovoltaic modules, so regularly cleaning the surface of the solar modules helps to increase power generation.   5. After-sales quality assurance: Professional after-sales service can guarantee the service life of the power station, extend the return on investment period, and avoid future worries.   Therefore, based on the above points, if you cannot change the sunlight conditions, here are some ways to outperform 99% of other home solar power station users in terms of power generation:   How to increase the power generation of your home distributed photovoltaic power station?   1. Strictly control the quality of the solar power station. Photovoltaic modules, inverters, and batteries are not typical consumer products; they have a lifespan of several years or even decades, but their long-term reliability should not be judged solely on appearance. To ensure the quality and long-term reliability of photovoltaic products and components, users can take the following measures:   (1) The most basic measure is to require manufacturers to provide authoritative test and certification reports to ensure that the technical performance of the products submitted for inspection meets technical standards and passes third-party testing, and that mass-produced products are manufactured according to the same standards as the products submitted for inspection;   (2) Since photovoltaic modules and inverters are not short-ter...

What is the current state of the global sodium battery industry? Will it reshape the current market landscape dominated by lithium batteries?   Regaining Market Attention Sodium batteries are rechargeable batteries that use sodium ions (Na+) as charge carriers. They operate primarily by the movement of sodium ions between the positive and negative electrodes, functioning similarly to lithium batteries.   In reality, sodium batteries are not a novel concept. Research into sodium batteries began almost simultaneously with lithium batteries in the 1970s. However, development stalled due to constraints in research conditions and other factors. Meanwhile, lithium batteries rapidly gained traction, achieving comprehensive coverage across consumer electronics, computers, communication networks, electric vehicles, and other sectors.   The current surge in battery raw material prices is placing immense pressure on rapidly expanding power battery manufacturers. Data indicates that the spot price of lithium carbonate averages around 89,000 yuan per ton, representing a roughly 67% increase since the beginning of the year. Similarly, the spot price of lithium hydroxide averages approximately 89,500 yuan per ton, surging by 80% year-to-date. This price hike is primarily driven by the rapid expansion of the electric vehicle and energy storage markets, which have fueled a sharp increase in demand.   Approximately 70% of the world's lithium resources are concentrated in South America, while China relies on imports for 80% of its lithium supply. To address this critical resource constraint, relevant companies are turning their attention to sodium batteries. It is understood that sodium batteries primarily use sodium salts as electrode materials, which are more abundant and less expensive than lithium salts. “Sodium chloride can't be hyped up because there's so much salt,” stated Zeng Yuqun.   Currently, about 20 companies worldwide are engaged in sodium battery R&D, including UK-based Faradion, Japan's Kishida Chemical, US firm Natron Energy, and China's Zhongke Haina, Sodium Innovation Energy, and Starry Sky Sodium Battery. In June 2018, Zhongke Haina launched China's first sodium battery-powered low-speed electric vehicle, marking a new chapter in sodium battery development.   Industrialization Faces Challenges Like Stability   “Sodium batteries can utilize existing lithium battery materials, cell production processes, and manufacturing equipment, presenting no significant bottlenecks for mass production,” Hu Yongsheng, a researcher at the Institute of Physics, Chinese Academy of Sciences, told reporters. Sodium batteries have gradually transitioned from laboratory research to practical applications. China currently leads globally in sodium battery product R&D, manufacturing, standardization, and market promotion, with the industry poised for commercial deployment.   So, will sodium batterie...

As 2026 begins, the three major foreign trade markets—the United States, Canada, and Europe—are experiencing a wave of policy changes. News of canceled export tax rebates, tariff reductions, and escalating cross-border tariff disputes has been rolling in. Let's take a look at what these new policies entail. U.S. Market: Export Tax Rebates Adjusted for Multiple Products The Ministry of Finance and State Taxation Administration recently announced that starting April 1, 2026, VAT export tax rebates will be eliminated for products including photovoltaic and ceramic goods. Battery products will have a transition period: from April 1 to December 31, the export tax rebate rate will decrease from 9% to 6%. Starting January 1, 2027, rebates will be fully eliminated. These adjustments may directly increase export costs for relevant products and are expected to trigger concentrated shipments to the U.S. market. For photovoltaic and ceramic products with existing orders, we recommend expediting logistics arrangements to avoid higher export costs after the policy takes effect on April 1. Battery exporters should seize the window before March 31 to arrange shipments and continue benefiting from the 9% export tax rebate rate.   Canada Line: Electric Vehicle Tariff Reduction Benefits On January 16, Canadian Prime Minister Justin Trudeau, during his visit to China, announced reduced import tariffs on certain Chinese electric vehicles. This adjustment allows up to 49,000 Chinese EVs to enter the Canadian market at a 6.1% Most-Favored-Nation (MFN) tariff rate. This tariff relaxation presents new opportunities for Chinese EV exporters to Canada. Relevant sellers should proactively arrange logistics and transportation to fully leverage this policy advantage, accelerate market expansion in Canada, and secure greater market share.   Europe Route: Escalating US-EU Tariff Trade Friction On January 17 local time, President Trump announced additional tariffs on eight European countries: Effective February 1, 2026, all goods exported to the United States from Denmark, Norway, Sweden, France, Germany, the United Kingdom, the Netherlands, and Finland will be subject to a 10% tariff. Effective June 1, the tariff rate will increase to 25% until European nations agree to the U.S. demand to “purchase Greenland.” This move has drawn strong opposition from Europe, escalating the tariff standoff between the U.S. and Europe. On the 18th, the U.S. Treasury Secretary publicly endorsed the policy, stating Europe would ultimately accept U.S. control over Greenland. Multiple European nations jointly condemned the U.S. actions and vowed retaliation. The EU is evaluating countermeasures, planning to impose tariffs on $93 billion worth of U.S. goods exported to Europe, potentially effective after February 6, while also considering freezing relevant U.S. market access.   While policy adjustments may trigger short-term market volatility, they also present...

The International Energy Agency (IEA) recently released its World Energy Employment Report 2025, indicating that employment growth in the global energy sector has nearly doubled that of the overall global economy. The core driver behind this growth trajectory is the sustained expansion of energy infrastructure investment.   Data from the report shows that by the end of 2024, global energy sector employment had climbed to 76 million people, representing a net increase of over 5 million compared to 2019.   Among various energy segments, solar power emerged as the dominant force driving new job creation in the electricity sector, accounting for 40% of all new positions globally. The manufacturing of system equipment alone—including inverters, solar panels, generators, and batteries—has absorbed approximately 3.5 million workers.   Regionally, China remains the core employment market for solar energy, accounting for 60% of the global workforce in this sector. Europe, India, and other Asia-Pacific nations each contribute around 10% of total employment in this field.   In terms of job structure, the solar industry's workforce is highly concentrated in the “development and installation” segment, with about two-thirds of employees engaged in new project development and installation-related work. Among them, personnel responsible for installing solar projects in private residences and utility-scale solar fields account for 46%; while those employed in the manufacturing of core equipment such as polysilicon, wafers, cells, and modules account for 21%.

According to the US Solar Market Insight Q4 report jointly released by Wood Mackenzie and the Solar Energy Industries Association (SEIA), the United States added 11.7 GW of new solar capacity in the third quarter of 2025, marking a 20% year-over-year increase and a significant 49% quarter-over-quarter surge.   By the end of Q3 2025, solar accounted for 58% of new grid-connected generation capacity nationwide, with cumulative installations surpassing 30GW. During the same period, solar and energy storage projects collectively contributed 85% of the nation's new generation capacity additions.   The report attributes this surge in installations to the concentrated release of backlogged projects. The report indicates that due to the impact of the Inflation Reduction Act, numerous PV projects were forced to halt in the second quarter. This quarter, these projects concentrated on completing their final stages, becoming the core factor driving the significant surge in installation data. However, behind the market's fervor, the industry's “tightening constraints” have not eased. During the third quarter, issues such as PV module shortages, delivery delays, and labor shortages intensified, forming a clear constraint on the market's continued expansion.   Notably, domestic PV production capacity in the United States is accelerating its expansion. In the third quarter of 2025, the country added 4.7 GW of new solar module manufacturing capacity, bringing its total industry capacity to 60.1 GW. Additionally, the new wafer production line at Corning's Michigan facility commenced operations, signifying that the U.S. has now established a complete solar manufacturing supply chain covering core segments including polysilicon, ingots, wafers, cells, and modules. Even so, the actual output from these domestic factories remains insufficient to meet domestic market demand.   Installation details across various market segments are as follows:   Residential Solar Market: New installations in Q3 2025 reached 1,088 MWdc, down 4% year-over-year and quarter-over-quarter. Despite industry efforts to rush projects online to qualify for this year's tax credits, constrained equipment supply emerged as the primary factor limiting capacity growth.   Commercial Solar Market: New installations reached 554 MWdc, marking a 9% year-over-year increase but a 12% quarter-over-quarter decline. California's continued grid connection of projects under the Net Energy Metering 2.0 (NEM 2.0) program supported stable installation levels in the state, though policy-driven growth momentum showed signs of weakening this quarter.   Community Solar Market: New capacity added in Q3 reached 267 MWdc, down 21% year-over-year but up 12% quarter-over-quarter. New Mexico saw its first projects under a four-year-old support program officially connect to the grid this quarter.   Large-scale Ground-Mounted Market: New installations reached 9.7 GWdc, up 26%...
