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

5%, 5 year loans

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

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
