Continuous Improvement of Solar PV Plants with Innovative and New PracticesSatya Kumar DV
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.
Bringing global best practices to India, Solarig Gensol Utilities maximises generation of a Solar PV Power Plant by a combination of sophisticated software & tools and a disciplined approach Operation & Maintenance.

2. Significance of PV Modules Quality
Gensol Group
The lack of Quality Standards in the industry has a negative effect on the quality of modules being installed in
the country today. Different manufactures follows different methodology for quality process.
It is very important to know the quality standardization
process of solar PV modules for Developer, Investor, EPC &
O&M Contractor in solar industry as failure of modules with
lead to huge loss.
3. Solar PV Module Performance Curve

includes two
principles:
"Fit for purpose"
(the product

suitable for the
intended
purpose);
"right first time"
(mistakes should
be eliminated).
For Assurance Inspection, same sets of tests are being performed as performed during manufacturing process. The final
testing process prior to deployment and is performed by a company tester who ultimately signs off on the product

Gensol Group
Aerial inspections (from drone or airplane) of PV power
plants are being conducted nowadays for defective or
underperforming modules and strings which are able to
detect module-level defects which cause temperature
differences in the module such as diode faults, cell hot-
spots, junction box heating and major differences in module
efficiency.
