Current Scenario India is endowed with vast solar energy potential About 5,000 trillion kWh per year energy is incident over

Indias land area with most parts receiving 4-7 kWh per

sq. m per day


8/38

Current Scenario

India just had 2.12 MW of grid connectedsolar energy generation capacity till 2007

The amount of solar energy produced in

India is merely 0.5% compared to otherenergy resources

The government has envisaged a capacity

addition of around 1000 MW by 2012.

The Thar Desert in India is also a

promising location for a solar energy.


9/38

Current Scenario

But at current pace of 20 percent annual

growth India could emerge as the fourth

largest market for solar energy after

Germany, Japan and China in the coming

years.

Why to Invest in SolarEnergy?

Installation is easy and you can expand over

time

Payback can be quick Solar Panels pay for

themselves

Help the environment with solar energy.

Solar Panels doesnt have to expensive

Tax Incentives (For example, in Australia, if you spend$16,000 on a solar set up, they will rebate you up to $8000

back. This doesn't include other rebates you can get either)

Why to Invest In SolarEnergy?

Limitations of SolarEnergy

Cost of producing solar energy is high (The cost ofproduction ranges from Rs 15 to Rs 30 per unit compared

to around Rs 2 to Rs 6 per unit for thermal energy)

Efficiency of conversion of solar energy to useful

energy is low (The energy collected by 1 m square of a

solar collector in a day is approximately equal to that

released by burning 1 kg of coal or 1/2 litres of kerosene)

Banks are highly hesitant to finance new projectsand developers are waiting for better returns in a

climate of decreasing module prices.


15/38

Limitation of SolarEnergy

Oversupply, coupled with the global financialcrisis, is hitting the solar industry hard(Fall in demandand rapid expansion of the more than 400 module manufacturers

worldwide, is putting module prices under pressure)

Solar Lantern Programme 2009-2010 It is proposed to take up deployment of 30,000

solar lanterns under 2006-07 SPV Programme.

The Ministry will provide a subsidy of Rs.2,400/-per solar lantern to the eligible beneficiaries in

the un-electrified villages, hamlets of the (i)Special Category States and the (ii) UT islands.

Solar Photovoltaic Programme 2009-2010

To promote the use of SPV systems for lightingand various other applications in the country.

To save diesel for power generation in institutionsand other commercial organizations

Government ActivitiesHighlights of Budget 20101.Custom duty has also been pegged a at

a low 5% on equipment for SolarPhotovoltaic and Solar Thermal Power.

2.These equipment will also be exempt

from central excise duties.3.Excise will also be reduced from 8% to

4% on Led Lights.4.An Unique solar powered rickshaw

developed by CSIR will attract a mere4% excise duty and its components willbe exempted from Customs duty.

5.Solar Powered and Electric Cars to beCheaper

Carbon Credits Carbon Offsets can be used to compensate forthe emissions produced by funding an

equivalent carbon dioxide saving somewhereelse.

1 kw of solar power with an average of 5.5 hours

of sunlight per day will produce 1 carbon creditper year.

1 carbon credit is equal to 1 ton of carbondioxide offset

So far 30 million carbon credits are generatedby India, in coming years 140 millions areexpected, with 650 energy efficiency projects

Conventional Solar Cells have only 10

percent Efficiency and have highmanufacturing costs

Use of Solar Nanotechnology willconsiderably lower the manufacturingcost

Chemists at the University of California,Berkeley, have discovered a way tomake cheap plastic solar cells thatcould be painted on almost any surface

Konarka Technologies are already

manufacturing a product called, PowerPlastic which absorbs both sunlightand indoor light and converts it intoelectricity, which has efficiency around8%.

IndiaIndia The Shirdi solar system which isbuilt with a cost of 133 lakh

rupees generates 3500 kg of steam enough to cook for 20,000 people

The whole system is installed in lessthan 10 months and it saves Shirdi

temple 20 lakh rupees per year (interms of the money spent on 1 lakh kgof LPG which they spend now)

40 solar parabolic concentrators movein the direction of sun and raise the

temperature of water which will thenproduce the steam.

not sell it to them.

Owning rights are still with Firm A and they willhandle any maintenance cost incurred

Firm B will only pay Firm A on daily basisaccording to the measure of usage done

Usage measured in no. of hrs or amount ofsteam generated etc.

Although practical on paper has not gainedpopularity in India due to Corruption & lack oftrust among businesses.
