With the photovoltaic industry shifting rapidly from traditional P-type to advanced N-type technology, module structures and electrical characteristics have undergone major changes. TOPCon, HJT and BC modules feature unique internal capacitance and back-contact structures, which pose new challenges to conventional IV testing equipment. Many ordinary testers fail to adapt to N-type module testing logic, resulting in distorted IV curves, unstable fill factor data and inconsistent power grading, which cannot meet modern high-efficiency module quality inspection standards. #NTypePVTesting
Yoha Solar’s IV Tester
Different from conventional P-type modules, N-type high-efficiency products have stricter requirements on testing sampling strategy and anti-interference capability. HJT modules with high capacitance require matched pulse duration for sufficient charge release, while BC back-contact modules are prone to signal interference during testing. Fixed testing modes of traditional equipment cannot adapt to multi-technique module production, forcing manufacturers to configure multiple testing devices and increasing production and maintenance costs. #PVModuleCompatibility
Tailored for the iterative upgrading of PV cell technology, the Yoha Solar IV Tester achieves full coverage of mainstream module testing scenarios, perfectly compatible with P-type, TOPCon, HJT and BC modules. All performance designs comply with IEC 60904-9:2020 international standards, solving the compatibility pain point of single-scenario testing of traditional equipment and realizing one-device multi-purpose detection. #YohaSolarIVTester
The equipment supports flexible adjustment of scanning speed and sampling strategies, adapting to the electrical characteristic differences of various N-type modules. It adopts professional anti-interference structural design for back-contact modules, effectively stabilizing signal acquisition. Equipped with A-level standard solar simulator with 300–1200nm complete spectral range, it supports adjustable irradiance of 700–1200W/㎡ to match diverse testing demands of high-efficiency modules.
This multi-compatible IV tester avoids repeated equipment investment for PV manufacturers with mixed production of multiple module types. It maintains stable industrial testing accuracy in long-term batch detection, ensuring consistent and credible electrical performance data for different technical modules. It effectively simplifies production line configuration, improves inspection versatility, and provides reliable standardized testing solutions for the upgrading and iteration of high-end photovoltaic products.
