New clarification added: QUESTION:We have noted that it is mentioned that no PPL certifications will be required to certify conformity of the system installation per the local regulations. From our previous experience, PPL is usually required to inspect and commission the systems in order to confirm successful installation and commissioning. Please share more insights on this.ANSWER:The system design has been developed based on site requirements and complies with local and international standards. The contractor is expected to perform installation and commissioning of systems in accordance with the approved design and specifications. Furthermore, the system does not require PPL certification to confirm its operation with network operator standards unless it is a grid-tied solution.
