TRANSCRIPT
Solar Power Plant Procurement's
COMPLETE PROCESS OF PROJECT EXECUTION
KEY PARAMETER FOR EFFECTIVE SOURCING
• Experienced Team – Should have experienced professionals. The management team is constituted by a highly experienced leadership team.
• Engineering Excellence – Focus on value based engineering, design and planning. • Quality Focus - Well-defined and stringent quality standards for supplier selection. Existing relationship with the tier 1 supplier
helps in ensuring the quality and timely execution of the projects.• Engineering – Re-engineering of complex processes in the most economical manner
– Resulting in increase in output and reduction in losses– Resulting in minimal cost over-run– Resulting in cost savings during execution
• Effective procurement – Procurement strategy driven by a deep understanding of vendors / contractors network in India and abroad.
– Ordering with established vendors to facilitate cost effectiveness & standardization– Explore & develop vendors for contingency– Efficient time management in finalizing, ordering & tracking of supplies
• Demonstrated capability in systems integration: An in-depth knowledge of PV plant design and optimization techniques for a wide spectrum of PV technologies.

SELECTION OF PV MODULES
KEY PARAMETERS FOR SELCTION OF PV MODULES:
1. Module shall be 320 Wp or higher with linear degradation.2. It should be PID resistant3. It should have 4 sq. mm cable with atleast 1200 mm length4. Current sorting shall be available for +_5% per pallet.5. Serial defect should not be present in the modules6. Have good reference in INDIA 7. It should have backing from Insurance co. such as Munich, RE8. It should have anti reflecting coating glass of 3.2 mm thickness.9. Power coefficient shall be low.10. Junction box shall have at least 3 bypass diodes and output cable shall be compatible with MC4 or MC4
compatible connectors.11. It should have 4 BB
SELECTION OF PV MODULES
KEY PARAMETERS FOR SELCTION OF PV MODULES:Validity of the documents including Certificates.- Compliance of the product (including Bill of Materials) with the required certifications designated by the manufacturer.- Compliance of the product with other related certificates required by the client, including but not limited to IEC62804 (PID). -IV test and curve analysis, including:Equipment validation | Annual calibration | Maintenance records | First and Second Reference Module validationTesting Procedure | Standard Operating Procedure validation | Frequency of calibration and recordsTest Results | Pmax (to be within the tolerance) | All electrical parameters including fill factor | IV curve- Electro-luminescence inspection- Visual InspectionWorkmanship defectsVerification of components visually and from manufacturer’s internal systemPackaging--BOM Verification as per agreed and certified specifications.
Module losses generally
account for major losses in
the system

TREND OF SOLAR PV PRICING
WHAT ARE THE REASON FOR THE DROP IN SOLAR SYTEM PRICING?
REASONS OF LOWERING OF SOLAR PV PRICING
1. Drop in Module Price.2. Optimization of Engineering i.e. DC: AC ratio3. Entry of New manufacturers in the market4. Customized solutions5. Increase in Size of the project6. Reduction in BOS price due to higher
efficiency of Modules7. Reduction in structure weight due to better
material like ZAM/ Galvalume
