Relaibility
Reliability at its best
Sunbond is Where Reliability is Built, Not Just Tested.
The Solar Module Reliability Laboratory at Sunbond Energy Pvt. Ltd. is designed to ensure that photovoltaic modules meet the highest standards of quality, safety, durability, and long-term performance. The laboratory performs a comprehensive range of mechanical, environmental, electrical, and material reliability tests to simulate real-world field conditions and verify module reliability over its operational lifetime.
These tests help ensure compliance with international standards such as International Electrotechnical Commission standards like IEC 61215 and IEC 61730 for photovoltaic modules.
