The portable EL tester is designed to detect hidden cracks inside solar panels, ensuring efficient power generation of photovoltaic modules. With a compact design, user-friendly operation, and high portability, it is ideally suited for mobile users requiring on-site inspections. This mobile testing tool is tailored for component inspection in solar power plants.

Portable Thermal Imaging Tester

This compact handheld infrared thermal imager is specifically designed for photovoltaic power plants to conduct temperature inspections on all electrical equipment. It helps identify potential faults, reduce maintenance costs, and ensure production safety.
Key features include one-handed operation for capturing images, a high-definition touchscreen display, and resistance to strong ambient light and laser interference.

Solar Module Multi-Channel Testing System

The outdoor module multi-channel testing system provides real-time synchronous multi-channel testing capabilities and supports customization of channel quantity and test module power according to specific user requirements. By networking multiple testers, it forms an evaluation system capable of simultaneously testing up to 300 photovoltaic (PV) modules, making it ideal for outdoor PV module performance comparison. The system enables comparative testing of multi-channel power generation efficiency, allowing side-by-side evaluation of IV characteristics and energy yield differences across different modules on the same time base. It also supports synchronous recording of multi-channel irradiance and temperature data, providing users with clear and intuitive test result analysis. This addresses the current need for real-world energy yield comparison testing of outdoor PV modules.
Additionally, the system features multi-channel/all-weather measurement output characteristics, automat

PV Inverter Power Quality Tester

The PV inverter power quality tester provides detailed recording and analysis of power quality parameters at photovoltaic power plant sites, including harmonics, voltage, current, frequency, voltage fluctuations, flicker, power, and three-phase unbalance. It also features advanced measurement functions such as power transient monitoring, waveform recording analysis, energy efficiency loss assessment, and inverter performance measurement, providing accurate data for managing grid-connected power quality in PV power plants. This equipment is characterized by high precision, wide frequency band, and broad measurement range.

Drone EL Tester

Designed for electroluminescence (EL) internal defect detection in PV power plant array components, this drone-based EL tester efficiently completes power plant quality inspection tasks. It supports switching between photo and video modes, facilitating third-party operation and maintenance (O&M) quality checks. Combined with fully automated focusing technology, the device enables flexible switching between multiple detection modes, making it the preferred tool for power plant inspection and O&M. Featuring long endurance, it is suitable for large-scale inspections, rapid mapping, high-definition imaging, and original data transmission.

Global Perspective | Millennial Solar Debuts at PVCON 2024 Academic Conference in Turkey

Date : 2024-07-09Views : 85

From July 3rd to July 5th, local time, the 4th International Photovoltaic Science and Technology Conference (PVCON 2024) hosted by ODTÜ-GÜNAM was grandly held at the Culture and Conference Center of Middle East Technical University, Turkey.

As a world-leading photovoltaic technology innovation company, Millennial Solar firmly promotes its global layout and actively expands overseas markets. Its professional team traveled to Turkey to attend the conference, showcase its excellent technology and solutions, and strongly supported the forum as a sponsor.

Turkey Solar Market Analysis

Policies:

According to the latest Turkey Solar Market Trends Report, solar photovoltaics (PV) are expected to dominate the market. The report states that in 2022, the Turkish government announced a government-supportive policy strategy at the COP27 climate summit to reduce greenhouse gas emissions by 41% below business-as-usual levels by 2030 and achieve net zero emissions by 2053. Clean energy technologies such as solar systems are essential. As a result, the solar market will see a surge in project installations.

In addition, according to China's customs export data in 2023, China's cell exports to Turkey reached 10.11GW, and the battery cells supplied by China accounted for more than 95% of the country's total imported battery cells, and the market development prospects are broad.

Market:

Against the backdrop of the growing demand for energy transformation, China's advanced photovoltaic products have shown a clear growth trend in exports to the Turkish market. From the demand side, Turkey, as the world's fourth largest module producer, is one of the markets with the largest overseas cell demand, with its manufacturing model mainly based on imports.

Turkey solar energy market size is expected to grow at a CAGR of over 6% during the forecast period (2024-2029).

Empowering Photovoltaics

The 4th International Photovoltaic Science and Technology Conference (PVCON 2024) is one of the most authoritative academic events in the field of photovoltaic technology in Turkey. During the conference, professionals from home and abroad discussed the new progress of photovoltaic technology and focused on the future development trend of photovoltaics. Focusing on global strategy and long-term development, Millennial Solar attaches great importance to overseas markets and vigorously promotes the layout of the Turkish market.

Participants in this PVcon forum included: Manager Yang from the Module Product Department, Mr. Xue, Project Planning and Marketing Director, and Ms. Jodie, Overseas Sales and Marketing Director.

Millennial Solar has a R&D and production team composed of top experts. Industry experts and customers from all over the world came to the booth in an endless stream, showing great interest in Millennial's advanced photovoltaic cell inspection technology and high-quality product solutions.
