REQUIREMENTS OF BEST QUALITY PV SYSTEMS HIGH PERFORMANCE

SAFETY

LONG TERM RELIABILITY

LIFE CYCLE COST (Rs./ kWh) ( GRID PARITY ?)

Best practices solar energy include . Programme Planning Setting Targets (physical, performance and cost reductions) Site specific and Need based PV SystemsUse of Standards with Indicators Growth of Industry: through put & reliabilityCreation of high quality testing laboratories Adoption of latest developments in technology

PHYSICAL:20,000 MW Utility Grid 2000 MW Off- Grid.100MW Roof Top InstallationsLighting Systems for 20Million Houses

RELIABILITY & LIFE :35 years for PV modules?COST:Grid Parity by 2020

JAWAHARLAL NEHRU NATIONAL SOLAR MISSION (JNNSM)(TARGETS)PHYSICAL:1050 MW Utility Grid 155 MW Off- Grid (Including Roof-top, Lighting, pumps all Off-Grid Systems)

RELIABILITY & LIFE :10% in 10 years and 15% in 20 years for PV modules

COST:Rs. 7- 9/ Wp
