Recently, JA Solar has hit another "milestone" in sustainable development! Its Fengxian and Yangzhou manufacturing bases aced the Solar Sustainability Initiative (SSI) audit and snagged the "Silver Medal" certification. This top - tier SSI accolade in the PV world shows JA Solar's ESG efforts are now a global industry benchmark.     Unlike other certification bodies, the Solar Sustainability Initiative (SSI) is the first initiative organization that focuses on the sustainability and traceability of the supply chain in the photovoltaic industry. This organization was jointly launched by SolarPower Europe and Solar Energy UK. Its aim is to unite manufacturers, developers, installers, and purchasers within the global photovoltaic value chain to jointly promote the responsible production, procurement, and management of photovoltaic materials, and it has a huge influence.   Thanks to the authoritative background of the Solar Sustainability Initiative (SSI), most of the key developers and suppliers in the global photovoltaic industry have joined the organization. The project scales held by member enterprises and the output of related photovoltaic products account for a crucial share in the global market. Among them, all SSI member enterprises from the manufacturing sector must complete a strict on-site assessment by a compliant independent assessment body (AB) approved by SSI within 12 months. As of now, there are only 7 eligible assessment bodies.   Right from the start of the Solar Sustainability Initiative (SSI), JA Solar was knee - deep in shaping its sustainable standards. Manufacturing bases in Baotou, Ningjin, Yiwu and other locations served as SSI's first - round sustainable capacity research pilots. They provided invaluable examples for putting those standards into practice. Then, in October 2024, JA Solar's Baotou base took the lead again as the audit pilot for SSI's brand - new standards. The SSI "Silver Medal" certification JA Solar just received is clear proof that the company has turned its standard - building know - how into real - world management wins. In recent years, JA Solar's headquarters and base departments joined forces. They overhauled a ton of systems, processes, and documents. This included biodiversity policies, carbon emission strategies, compliance risk management, life - cycle circularity plans, EHS targets, and control procedures. By constantly ramping up their sustainability efforts, JA Solar aced the SSI on - site audit with flying colors. This SSI certification is a huge milestone for JA Solar, but it's just the beginning. Looking ahead, JA Solar is set on getting more of its manufacturing bases SSI - certified. The company also aims to blend sustainable development even deeper into its business operations. What's more, JA Solar will be right there, helping partners build their sustainable capabilities. With JA Solar at the helm, the global PV value chain is on track to create a far more responsible and resilient ecosystem. If you haven't owned it yet, hurry up and contact us!

On March 26th, Jinko Solar released the Q4 and full - year 2024 financial results of its controlling shareholder Jinko Solar Holding Co., Ltd. , as well as the shipment forecasts for Q1 and the whole year of 2025. The announcement shows that in Q4 2024, JKS's total shipment volume reached 26,462 megawatts (including 25,221 megawatts of solar modules, 1,241 megawatts of solar cells and silicon wafers), representing a 2.1% quarter - on - quarter increase and a 5.0% year - on - year decrease. The revenue in Q4 2024 amounted to RMB 20.65 billion (US$2.83 billion), a 15.7% decline quarter - on - quarter and a 37.1% decrease year - on - year. The quarter - on - quarter and year - on - year decreases were mainly due to the decline in the average selling price of solar modules.   In 2024, JKS's shipment volume reached 99,596 megawatts (including 92,873 megawatts of solar modules, 6,723 megawatts of solar cells and silicon wafers), a 19.2% year - on - year increase. The total revenue in 2024 was RMB 92.26 billion (US$12.64 billion), a 22.3% year - on - year decrease. The decrease in total revenue was mainly due to the decline in the average selling price of solar modules.   JKS expects the module shipment volume in Q1 2025 to be between 16 gigawatts and 18 gigawatts, and the module shipment volume for the whole year of 2025 is expected to be between 85 gigawatts and 100 gigawatts.

As solar power becomes an increasingly popular energy solution, many people still wonder: 👉 Do solar panels work on cloudy or rainy days? 👉 How much electricity can they produce without direct sunlight? 👉 What is the science behind how solar panels generate electricity in the first place?   This article explains everything you need to know about solar panel performance in all weather conditions, especially cloudy and overcast days.     How Do Solar Panels Work? At the heart of every solar panel is the photovoltaic effect—a process that converts sunlight directly into electricity. 🔬 Here's how it works: Sunlight hits the solar cells, usually made of silicon. Photons (light particles) in the sunlight energize electrons in the silicon atoms. Energized electrons are knocked loose and start flowing, creating direct current (DC) electricity. An inverter converts DC to alternating current (AC), which powers your appliances or gets stored in batteries. 📌 In short: Light energy → Electron movement → Electricity. That’s the core of a solar photovoltaic system.     Do Solar Panels Work on Cloudy Days? Absolutely—solar panels can still produce electricity on cloudy, foggy, or even rainy days. Here’s why:   Diffuse sunlight still penetrates clouds. Even when the sun is hidden, there is enough ambient light for solar panels to absorb. Photovoltaic cells respond to all visible light, not just direct rays. Light is scattered by moisture and dust, but still carries enough energy to trigger the photovoltaic effect. If you can see outside during a cloudy day, then there’s enough light for solar panels to generate power!     How Much Efficiency Is Lost in Cloudy Weather? Cloudy conditions do reduce output, but they do not stop solar production. The extent of the drop depends on the thickness of the clouds, the panel technology, and time of day. Here’s a general reference table:   Weather Condition Light Intensity (W/m²) Approx. Power Output ☀️ Clear & Sunny ~1000 100% 🌤 Partly Cloudy 500–700 50%–80% ☁️ Overcast 200–400 20%–50% 🌧 Rainy/Stormy <200 5%–20%   💡 Example: If your solar system produces 10 kWh on a sunny day, it may still produce 2–5 kWh on a cloudy day. Important note: Solar panel performance in low light varies depending on:   Panel technology (monocrystalline vs. polycrystalline vs. thin-film) Inverter type (especially MPPT-enabled systems) Installation angle and orientation Presence of shade or dirt   How to Optimize Solar Panel Performance in Cloudy Conditions Here are expert tips to maximize energy yield even on less sunny days: 1. Use high-efficiency solar panels Monocrystalline panels perform better in low light than polycrystalline ones. Thin-film panels such as CIGS (Copper Indium Gallium Selenide) perform better in diffuse light and cloudy conditions. 2. Choose MPPT inverter systems MPPT (Maximum Power Point Tracking) technology continuously adjusts voltage and current for optimal performance under fluctuating light. 3. Install at optimal angles Proper tilt and orientation (usually south-facing in the Northern Hemisphere) help capture the most light, even on overcast days. 4. Add energy storage Solar battery systems store excess energy from sunny days for use during cloudy days or nighttime.     Conclusion: Solar Power Works Rain or Shine Solar energy isn't just a fair-weather solution. Thanks to advanced solar technologies and intelligent system design, solar panels can produce power year-round, even in cloudy or rainy regions. ☀️ Key takeaway: Solar panels don’t need direct sunlight—they just need daylight. As long as there’s light, there’s electricity.   📞 Ready to go solar—even in cloudy areas?
