2  Increasing energy demand - supply gap  Need to reduce dependence on fossil fuels  Increasing cost of electrification to cover villages in far-flung and remote areas  High availability of solar, wind, biomass and hydel resources in India  Small size, modularity and low gestation periods which favour quick capacity additions  Successful demonstration of renewable energy technologies and their viability with declining costs  Increasing environmental concerns which favour renewables as they are environmentally benign

3  Railway sector growth 8-9%. Metro very fast rate  Progressive shift of freight traffic to railways  80% of rail freight and 60% passenger traffic on electric energy by 2030  Electricity demand to go 100 billion kWh by 2030 for railway sector alone in India.  The current trends indicates constraints in indigenous availability of conventional energy resources.  Increasing cost of Conventional Power and decreasing trend in cost of Renwable Power  World trend to achieve min. 25% through RE by 2020 in transport sector leader Germany, Sweden, USA.  Current share of RE Power is 13%(installed Capacity) which is planned to 20% by 2030  Fuel diversity  No space constraint in Railways

6  Indian solar PV market has seen significant growth with the installed capacity rising from under 40 MW to more than 2,000 MW in last four years  Solar power generation is expected to be 12,500 MW by , whereas only roof top solar is estimated to be 4,000 MW.  Rooftop SPV will drive solar power capacity additions given the acute power shortage in several states and also reduce transmission and distribution losses. Grid-connected SPV Rooftop systems MNRE

7  Refers to SPV systems installed on rooftops of residential, commercial or industrial premises.  Electricity generated could be -fed into the grid at regulated feed-in tariffs or -used for self consumption with net- metering approach Grid-connected SPV Rooftop systems MNRE

8 Grid-connected SPV Rooftop systems MNRE

9 Type-I: Electricity from PV system - not directly supply to the loads It is a simple and most cost effective Rooftop Solar PV system which doesn’t affect household grid connection and wiring. Grid-connected SPV Rooftop systems MNRE

10 Type-II: Grid-tie without battery backup – do not supply during outage Type-III: Grid-tie with battery backup – supply during outage Sites with reliable grid power, this is usually the logical system choice as It doesn’t provide backup power during a power outage even if the Sun is shining It has the added feature of batteries in order to power some selected backup loads when there is power outage. Grid-connected SPV Rooftop systems MNRE

11 Type-IType-IIType-III Simple and most cost-effective PV system It supplies surplus excess electricity produced to the utility grid Doesn’t affect the household grid connection and wiring Sites with reliable grid power, this is usually the logical system choice It has the added feature of batteries in order to power some selected backup loads during outage. Solar energy can’t be used directly at the consumer point It doesn’t provide backup power during power outage even if the Sun is shining The benefit of supplying backup power increases complexity and maintenance requirements Electricity generated from PV system is lost during power outage This system is expensive than other two types of systems Grid-connected SPV Rooftop systems MNRE
