Commissioning is the Quality Assurance (QA) system driven to achieve efficient design & installation, unremitting operation, and testing, as well as maintenance processes of solar plants. Only after the commissioning is complete, the PV systems can be plugged into the Grid. Each Module system needs to be commissioned and verified by a Special Commissioning Committee, which is certified by the corresponding agencies. The process ensures that systems are safe and can start performing in line with their technical specifications. We develop commissioning plans to protect the investments into solar PV systems ensuring the life span of our solar plants. Our activities assist the project owners and the investors to maximize the return on their investment. The commissioning will help to predict possible problems that might arise during the operation of the solar plants.
