A presentation on the Technical Paper accepted at NTPC's O&M Conference, Indian Power Stations (IPS) 2016, 13th February 2016, New Delhi - 'Continuous Improvement of Solar PV Plants with Innovative and New Practices' based on the experience of performance monitoring with ACTIS - the world's first Solar ERP software by Alectris, Greece. The presentation was made by DV Satya Kumar, MD, Shri Shakti Alternative Energy Ltd, the Partner for ACTIS in India. Continuous improvement concept is very much part of many existing industries and utilities and is called Deming's wheel or Kaizen approach. But the concept is new to Solar O&M industry and is made easy through continuous and close performance monitoring with ACTIS software and data loggers which provide in-depth analysis and reports compared to a SCADA system. This can lead to interventions and actions that improve the plant performance. Performance improvement is possible in any of the three categories of plants, defined herein, wherein the effort required versus the performance improvement achieved vary based on the baseline level performance of the plant before deployment of ACTIS and continuous improvement approach.

2. Key Highlights

3. Classification of Solar PV Plants

4. Potential for Improvement in all 3 Categories !

5. Common KPIs in Solar Industry
• Developers typically use PR and AVA to evaluate the
EPC / O&M contractor performance
• very useful as long as the raw data of the calculations is
precise and coherent
• Banks and Investors are more concerned about Actual
Vs Base case scenarios
• useful tool for evaluating the financial performance of an
asset, it is less useful for technically evaluating a Plant
