Large-Size BIPV Module IV Tester
The Large-Size BIPV Module IV Tester is a high-precision testing device specifically developed for the increasingly popular large-size and irregularly shaped modules in the Building-Integrated Photovoltaics (BIPV) field. It comprehensively measures current-voltage (IV) characteristic curves, power output, efficiency, and key mismatch parameters (such as hot spot effects) to accurately verify the actual power generation performance, long-term reliability, and safety of these special modules in complex building-integrated environments (e.g., non-uniform illumination, temperature gradients, partial shading). It features strong physical compatibility (large size, curved surfaces, transparent area handling) and high-power load capacity to meet stringent requirements for laboratory R&D, production line quality control, and partial post-installation field inspection.
Product Features
Exceptional Physical Compatibility: Designed specifically for BIPV modules larger than 3.5m×2.3m, including curved, transparent, and irregular shapes. Equipped with adjustable fixtures and a flexible contact system for non-destructive and precise adaptation.
Realistic Environmental Simulation Testing: Integrates adjustable illumination (200-1200W/m²) and temperature measurement platforms to simulate lighting conditions, temperature gradients, and low-light scenarios. Intelligently diagnoses hot spots and mismatch risks.
High-Precision IV & Safety Verification: Current and voltage measurement accuracy reaches ±0.8%. Comprehensively acquires 23 key parameters (e.g., Voc, Pmax). Integrates DC 3000V insulation withstand voltage and leakage current monitoring to ensure electrical safety in building applications.
Full-Scenario Intelligent Application: Seamlessly covers laboratory R&D (multi-variable analysis), high-speed full inspection on production lines (15 seconds/module), and on-site acceptance (portable split design). Generates cloud-based performance degradation models via IoT, empowering full lifecycle management.

Product Applications
BIPV Module R&D Verification: Serves photovoltaic laboratories and research institutes. Precisely quantifies the IV characteristics of irregular modules (curved/transparent) in simulated building environments (dynamic lighting, temperature variation, shading), supporting the iterative design of new BIPV materials and structures.
Full-Process Production Line Quality Control: Integrated into PV manufacturing lines. Completes power binning, hot spot screening, and safety performance (insulation/withstand voltage) full inspection for oversized modules within 15 seconds, ensuring zero-defect delivery for building-integrated applications.
Construction Site Acceptance Assessment: Adaptable for high-altitude/confined space operations. Retests IV curves of installed BIPV facades and roofs using portable split equipment to verify transportation and installation losses, ensuring initial system performance meets standards.
Building Operation & Maintenance Fault Diagnosis: Periodically connects to the cloud database. Compares historical IV data to intelligently locate degradation anomalies (e.g., hot spot deterioration, wiring faults), providing decision-making basis for preventive maintenance of building PV systems.
