All Manufactured modules are tested 100% by EL (Electroluminescence)
Our polycrystalline PV module series runs from 3W to 300W.
Sonali Solar can design and manufacture solar modules for any
Our automated assembly line includes a first of its kind electroluminescence tester in India. This allows us to find the types of micro cracks that most manufacturers are incapable of detecting, leading to improved product quality and reliability. Also, we ship directly from the factory in most cases, ensuring minimal damage caused by travel to and from warehouse space. Our panels are backed by a 5 year guarantee on material and workmanship and a 25 year guarantee on minimum power output. We also warrant that our customer will receive 100% of the panel’s rated power at the time of purchase.
Sonali Solar guarantees for 5 years from the date of shipment that our Solar PV modules are free from all defects in material and workmanship. Any defect found shall be replaced free of charge within the warranty period. Sonali Solar further guarantees the rated power output of its modules for a period of 25 years from the date of purchase. This guarantee affirms that the output will be at least for 90% of the minimum power output during the first 10 years and 80% of the minimum power output in the next 15 years.
