Solar PV Module Testing Services

 Presto Laboratories Pvt. Ltd. gives an in-depth testing of solar photovoltaic (PV) modules to analyze their functionality, stability, and safety in stipulated environmental and electrical damage factors. All the tests are conducted according to IS 14286, IEC 61215, and IEC 61730, and any PV modules that are designed and qualified are well qualified in terms of type and safety before deployment in the field.

During the service life of solar PV modules, they are constantly subjected to temperature variations, humidity, UV radiation, mechanical loads, and electrical loads. Testing according to IS and IEC standards is necessary in order to :

• Confirm stability of long-term reliability and performance.
• Determine susceptible design or material flaws at an early stage.
• Assure safety of electricity and fire of the module construction
• Address statutory and customer-specific compliance needs.
• Support BIS certification, project qualification, and export approvals

We follow the prescribed test sequences and acceptance criteria defined in the relevant standards to provide objective, repeatable, and traceable results.

What We Test

Design Qualification / Performance Testing

(IS 14286 / IEC 61215)

Design qualification testing is used to check the capability of a PV module design to endure accelerated environmental and mechanical stress loads without more than normal performance depreciation.

At Presto Laboratories, this includes a structured sequence of tests such as:

• Initial performance measurement under standard test conditions
• Thermal cycling tests for temperature variation and solder joint fatigue
• Damp heat exposure for prolonged humidity and high temperature resistance
• Humidity-freeze testing for moisture ingress and freezing stress
• Mechanical load testing for wind and snow load simulation
• Hot-spot endurance and bypass diode tests
• Post-test performance verification for power degradation assessment

Each test is conducted strictly as per the durations, cycles, and conditions defined in the applicable standards.

Safety Qualification Testing

(IEC 61730 Series)

Safety testing focuses on minimizing the risk of electric shock, fire, and mechanical hazards during normal operation and foreseeable fault conditions.

Safety qualification tests include:

• Dielectric withstand and insulation resistance tests
• Wet leakage current measurements
• Ground continuity verification
• Polarity and accessibility checks
• Constructional assessment of materials and layout
• Mechanical robustness and impact resistance tests
• Fire safety and flammability-related evaluations

These tests confirm that the module design provides adequate protection to installers, users, and maintenance personnel throughout its operational life.

Environmental & Special Condition Testing

Where required by project specifications or installation environments, additional tests may be carried out, including:

• Salt mist corrosion testing for coastal and high-salinity regions
• UV exposure testing for long-term material resistance
• Extended damp heat or customized environmental cycles

The test of the solar PV modules is based on specified apprehensions of Indian and international standards. These standards assist in maintaining the uniformity of results, traceability, and acceptability of the results in the domestic and export markets.

IS 14286 and IEC 61215
• are based on quality design and performance assurance.
• These standards define test conditions such as thermal cycling, damp heat exposure, humidity freezing, and mechanical load testing.
• They help study long-term behavior and measure power degradation under controlled stress conditions.
IEC 61730 Part 1 and Part 2
• cover safety qualification requirements.
• They check insulation strength, leakage current limits, and resistance to fire risks.
• They also verify protection against electric shock and review material quality and construction design.
IS 16170 and IEC 61853
• deal with performance rating under varying environmental conditions.
• These standards help understand how modules perform under real field conditions.
