 Quality Control (QC) and Quality Assurance (QA) during the first-time acceptance of solar projects involving Greenko (owner/developer), Waaree (module supplier/EPC), and Operations & Maintenance (O&M) teams focus on rigorous inspection, testing, and documentation to ensure long-term, high-performance assets. Greenko utilizes an Integrated Renewable Energy Storage Project (IRESP) approach, requiring advanced 3rd party inspections and in-house QA/QC teams for monitoring critical, first-time activities, supported by tools like Greenko Energy Project Systems (GEPS). Waaree, as a Tier 1 supplier, provides NABL-accredited, high-efficiency (TOPCon/PERC) modules that undergo rigorous QC, including EL and flash tests, to meet stringent project performance requirements. 1. Quality Assurance (QA) During First-Time Acceptance QA focuses on the processes, standards, and documentation to prevent defects. Engineering Document Review: Ensuring as-built drawings match the design and that all specifications are documented in the Quality Management System.Third-Party Inspection (TPI): Engaging independent, certified agencies to inspect critical components (modules, inverters) before dispatch to the site.Pre-Dispatch Inspection (PDI) Protocol: Ensuring Waaree modules and electrical equipment are tested according to IEC/BIS standards before leaving the factory.Vendor Audits: Auditing Waaree's production facilities to verify manufacturing quality, such as in-house testing labs.Documentation Handover: A thorough handover process is critical, including transferring all technical manuals, warranties, and commissioning reports to the O&M team to avoid performance loss. 2. Quality Control (QC) During First-Time Acceptance QC focuses on the technical inspection and testing of the installed equipment. Module Inspection (Waaree Modules):Visual Inspection: Checking for cracks, scratches, delamination, or breakage (general inspection level II).Flash Testing: Verifying that the modules meet the rated wattage (Flash test performed as per IEC 61215).Electroluminescence (EL) Test: Detecting micro-cracks and Potential-Induced Degradation (PID).Mechanical & Structural Check:Mounting Structure (MMS): Verifying structural integrity, proper torque, and corrosion protection (galvanization).Alignment: Ensuring proper tilt and in-line, aesthetically acceptable module installation.Electrical Inspection & Testing:String Testing: Verifying open-circuit voltage (\(V_{oc}\)) and short-circuit current (\(I_{sc}\)).Insulation Resistance Test: Checking cable insulation integrity to prevent ground faults.Inverter Efficiency Tests: Validating performance under site conditions.Earthing and Safety: Ensuring all metallic parts are grounded and that safety signage is in place. 3. O&M Handover and Post-Commissioning Quality Initial Punch List (Snag List): Identifying any defects found during the first-time inspection for rectification by the EPC contractor.Performance Ratio (PR) Test: Conducting a guaranteed Performance Ratio test over a 7-day or 30-day period to ensure the plant meets design expectations.Advanced Diagnostics: Deploying infrared (IR) thermography for 100% of the modules to detect hotspots and diode failures.Documentation and Training: Finalizing the Operation & Maintenance Manuals and providing training to the O&M team for efficient operation. Key Components for Success Greenko’s GEPS: A specialized, cutting-edge, and web-based system for real-time monitoring of quality, material, and logistics.Waaree’s NABL Certification: Waaree ensures quality through NABL-accredited labs, performing over 48 tests (thermal cycling, humidity, etc.).Environmental & Safety Standards: Strict adherence to site-specific conservation and safety plans.
