Environmental, Health, Safety, and Quality (EHSQ) monitoring at the field level during the first-time acceptance of a solar plant ensures that the project is compliant with regulations, safe for operation, and meets performance guarantees. This crucial phase—often involving Factory Acceptance Tests (FAT) and Site Acceptance Tests (SAT) or Commissioning—requires a systematic checklist to verify all components.
During this first-time acceptance, key EHSQ monitoring areas include Safety, Environmental, Quality Assurance, Technical Compliance, and Documentation checks.
Key EHSQ Monitoring Areas
Safety Monitoring (HSE): This involves verifying compliance with the Permit to Work (PTW) system, Lockout/Tagout (LOTO) procedures during component trials, and proper use of Personal Protective Equipment (PPE). Functional testing of emergency systems and structural safety inspections are also crucial.
Environmental Monitoring: Focuses on proper waste management, including the disposal of construction debris and packaging materials, and ensuring site restoration after installation.
Quality Assurance & Technical Compliance (Q): This includes visual inspections of components like modules, inverters, and cables for any damage. Electrical testing is conducted on both DC and AC sides, including insulation resistance and voltage tests. Earthing resistance is tested, and random torque testing of fasteners is performed. Functional testing verifies inverter start-up, grid synchronization, and AC output.
Documentation Check: This involves verifying as-built drawings match the installed configuration and reviewing manufacturer test certificates for key components. Compliance reports, such as safety clearances and net-metering approvals, are also checked.
First-Time Acceptance Procedure
The procedure typically involves a visual inspection of the site, followed by cold commissioning (before power) to perform insulation and earthing tests. Hot commissioning (after power) includes energizing the system and verifying voltage, current, and grid synchronization. A performance check verifies the inverter's output and ensures all components are functioning before final sign-off.
