Kerosene Lantern vs. Solar PV Kerosene Lanterns Solar PV
• Inconvenient• Dim light• Smoke • Risk of fire• Does not run appliances• Scarcity of supply• Recurring costs
• Convenient - flip of a switch• Bright, cool white light• Clean / healthy • Safe • Runs all appliances• 1 time investment• Saves money
Solar PV delivers better light for lower cost

Diesel vs. PV for back up power (low loads)
Diesel Genset Solar PV• Inconvenient• High-maintenance• Create a lot of noise• Smoke / pollution• Dangerous - risk of fire• High running cost
• Consumption of fuel and oil• Cost of maintenance
• Much more convenient
• No need to manually start • Virtually maintenance free• No fuel collection / filling
• Pleasant to use • Quiet • No pollution • Very safe
• 1 time investment• Saves money at low loads
10% down-payment, up-front costs are lower

• MNRE – Ministry for New and Renewable Energy, founded in 80s
• ‘Nodal agencies’ per state• Around 300,000 SHS over 20
years < 1 % of unelectrified households in India
• To improve diffusion of solar PV it is critical to engage private sector finance
• See examples of Sri Lanka and Bangladesh
Sri Lanka – 100,000 SHS over 7 years• 5 banks, 13
competing solar firms by 2006
• 15% down payment, commercial loans 1- 5 years
• 100,000 systems reached in 7 years
• Equivalent to 15% of unelectrifed households
Bangladesh – 100,000 SHS over 5 years
• 15 NGOs / firms that also provide finance
• 10% down payment, commercial loans 1-3 years
• 100,000 systems reached in just 5 years
Policy Pilot in India – Low Interest Finance
• UNEP programme 2004-2006
• Loans 5 years, 5% interest
• Syndicate and Canara Bank
• 5 participating vendors
• 14,000 systems in just 2 years in just one state

Use low interest finance to drive PV market• Low interest finance works for
solar water heaters: 2%, 5 years
• Recommendations for PV– 2%, 5 year loans up to 1 lakh– Cap per loan - 10 lakh– Set minimal specifications– Allow private banks to
participate• Benefits to GoI
– Investment into rural areas / jobs
– Displace kerosene and diesel– Reduce load on stretched grid– Improve power in rural homes
Solar thermal and PV –ideal combination
New PV Grid Connect Policies in India
• Jan 2008: MNRE created a new feed-in subsidy– State Electricity Board: Rs 3-4 per unit (8-10 US cents)– MNRE Subsidy: Max Rs 12 per unit (30 US cents)– Total: Max Rs 15 per unit (37-38 US cents)
• No accelerated depreciation• Subsidy for 10 years only• Max 5 MW per developer, 10 MW per state• Target: 50 MW in 2009, 500 MW over 5 years
Moving into Grid Connected Solar
Typical 1 MW Solar PV Power PlantSolar modules•Type - Silicon Solar Cells•Module power - 210 Wp each•Number of Modules - 4762
Inverter•Type - Indoor, Vertical Mount•Capacity - 500 kVA•Units - 2 nos.•Output voltage - 660 V•Control - IGBT high frequency
(20 kHz), 3 phase, 4 wire
Orb’s Value Proposition for Grid Connected Solar

Big scope for grid connected solar in India• Today only 2-3 MW of grid connected systems in
India, but big potential • Ideal solution for India with the solar radiation ranging
from 4 – 7 kWh / sq meter / day• Technology for solar grid connected systems has
matured – no technological barrier for growth• MNRE policy, incentives and regulatory frame works
can help make solar grid connected systems a viable investment proposal (currently around 10% IRR ?)
• Feed in tariff and net metering has huge potential to meet peak energy demand - Other Indian states to learn from WB.
• Strong interest for ‘green reasons’ – e.g. green buildings
Key part of India’s renewable energy future“....to deliver a sustained growth of 8% through 2031,
India would, in the very least, have to grow its primary energy supply by 3 to 4 times and electricity supply by 5 to 7 times of today's consumption. By 2031-32, power generation capacity would have to increase to 778,095 MW....”
(Integrated Energy Policy Report, August 2006)
– Today 140,000 MW and 7.5% renewables – Former President Kalam’s call: 25% renewables by 2030– Would mean growth from 10,000 MW to 195,000 MW in 20 years !!– Solar has a key role to play in meeting this target
