Taian Test: Customized climatic Reliability Testing Solutions for Indian Solar Manufacturers.

Project Overview Client: Multiple solar module and component manufacturers across India Core Equipment: Temperature & Humidity Cycling Chamber, Salt Spray Chamber Core Goal: Help PV products pass IEC 61215, IEC 61701 and BIS certification, adapt to India’s diverse harsh climates, and control long-term operational reliability

India’s solar industry is expanding rapidly, with numerous manufacturing bases distributed across inland high-temperature areas and coastal regions. Solar panels, junction boxes, metal frames and other core components are exposed to extreme temperature fluctuations, high humidity and salt corrosion all year round. These complex natural conditions easily cause product delamination, poor welding and metal rust, shortening service life.

Local solar manufacturers faced prominent testing dilemmas. Imported testing equipment has high procurement and maintenance costs, and cannot be quickly adjusted to adapt to local power supply and workshop environments. Conventional domestic equipment fails to meet the strict parameter requirements of international and Indian local certification standards. Many enterprises struggled to obtain accurate test data, resulting in prolonged certification cycles and unstable product quality, which restricted market expansion. Facing the dual pressure of quality inspection and cost control, local manufacturers were eager for cost-effective, standard-compliant and easy-to-maintain professional testing solutions.

Combining years of experience in environmental testing equipment R&D and the actual working conditions of India’s photovoltaic industry, Taian Test launched a targeted one-stop solution focusing on temperature & humidity cycling chambers and salt spray chambers, covering product R&D testing, sample certification and mass production quality inspection.

The temperature & humidity cycling chamber is optimized for India’s large temperature difference environment. It supports a temperature range of -40℃ to 85℃ and 10%–98% adjustable humidity, realizing rapid temperature cycling and long-term damp heat testing. The equipment adopts high-precision control components to ensure uniform internal temperature and humidity, stably simulating inland extreme weather. It can effectively detect hidden defects such as module power attenuation and solder joint detachment, fully complying with the thermal cycle and damp heat test clauses of IEC 61215. We also provide multiple specifications to match small R&D laboratories and large production workshops, balancing space utilization and testing efficiency.

For coastal salt corrosion problems, our upgraded salt spray chamber strictly follows IEC 61701 standards. With a 5% sodium chloride solution and 35℃ constant test temperature, it features excellent sealing to prevent salt fog leakage and equipment self-corrosion. It supports continuous and intermittent salt spray tests, comprehensively verifying the anti-corrosion performance of solar metal accessories. The wearing parts adopt universal models in the Indian market, greatly reducing the difficulty and cost of later replacement and maintenance.

Beyond equipment supply, we delivered full-cycle services. Before delivery, we adjusted equipment parameters to adapt to local voltage. After arrival, our technical team completed on-site installation, commissioning and operational training. A localized service team provides rapid after-sales response to solve equipment faults and parameter debugging problems in a timely manner.

After deploying Taian Test’s testing equipment, Indian solar manufacturers have achieved remarkable results. All test data is recognized by NABL and BIS certification institutions, cutting the product certification cycle significantly. The pass rate of environmental reliability tests for solar products has been greatly improved, and the failure rate of products in outdoor operation caused by climate factors has dropped obviously.

With stable performance and reasonable overall costs, our solutions have won wide recognition from local enterprises. Up to now, our temperature & humidity cycling chambers and salt spray chambers have been widely used in solar factories and third-party testing laboratories across North, South and West India. Reliable testing capability not only helps clients stabilize product quality, but also enhances their core competitiveness in the local and South Asian solar markets.

Reliable environmental testing is the solid foundation for the long-term operation of solar products. Taian Test always focuses on the actual demands of overseas clients, and creates cost-optimized and standard-compliant testing solutions based on regional climatic characteristics and industry rules. In the future, we will continue to deepen cooperation with Indian photovoltaic partners, continuously optimize product performance and service system, and contribute to the high-quality development of India’s renewable energy industry.
