Success StoriesThird-Party Inspection and Validation of Solar PV Power Plant
(Chandigarh Renewal Energy and Science & Technology Promotion Society)

Background

As per the target set for the Jawaharlal Nehru National Solar Mission (also known as the National Solar Mission) which is an initiative of the Government of India and State Governments to promote renewable energy, especially solar power. The inspection and validation is imperative for the solar power plants in order to maintain the quality of the power plant.

Introduction

The project was about the inspection and validation of the Grid Interactive rooftop SPV power plants and its components for aggregate capacity of 330 kWp at 8 Nos. different Govt. Buildings in Chandigarh as per the Technical Specification provided in the Bidding/Tender Documents according to international standard IEC 62446.

Activities

The broad scope of work includes: Conduct On-site Inspection, and Validation of Solar PV Power Plants, in co-ordination with CREST and the other concerned authorities; Preparation of Detailed PV System Inspection, and Test Reports (including, PV System Verification Certificates) for On-site Inspection, and Validation of Solar PV Power Plants.
