Potential of Solar Energy in India

2

Solar energy is radiant light and heat from the sun harnessed using a range of ever- evolving technologies such as solar heating, solar photovoltaics, solar thermal energy, solar architecture.

Active Mode : This technique include the use of PV systems, concentrated solar power and solar water heating to harness the energy.

Passive Mode: This technique include orienting a building to the sun, selecting materials with favourable thermal mass or light dispersing properties and designing space that naturally circulate air.

Mode of Capture

India is blessed with abundant solar insulation for 300 clear, sunny days in a year.

India’s theoretical solar power reception on only its land area is about 5,000 trillion kwh/year.

The daily average solar energy incident over India varies from 4 – 5 kwh/m2 with about 1500- 2000 sunshine hours per year.

In the budget for 2010/11 the government has announced an allocation of 1000 crore towards the Jawahar Lal Nehru National solar mission and the establishment of clean energy fund.There are some initiatives of MNRE Govt of India:Solar PV system for individual houses.Promotion of solar PV systems in urban areas.Urban solar cities programs.Solar water pumping system to support agriculture.

The Ministry of New and Renewable Energy provides 70% subsidy on the installation cost of a solar PV power plant in north east states and 30% subsidy on other regions. - Housing complexes : @ Rs.1900 /- per sq. m.- Institutional buildings : @ Rs.1750 /- per sq. m.- Commercial buildings : @ Rs.1400 /- per sq. m.

Subsidy System

11

FOR USERS:- ‐1.Soft loan @ 2% to domestic users, 3% to institutional users and 5% to industrial/ commercial users from IREDA, Public/private sector banks, scheduled cooperative banks etc.2. Loan up to 85% of the cost of the systems, repayable over a period of 5 years.

Concessional loan provisions through interest subsidy by MNRE

Solar power from SPV system and solar concentrating system is produced in environmental friendly manner.

Does not generate any waste or pollution.Meets the energy requirement in domestic sector in

decentralized manner quite efficiently.Best suited for off grid application in stand alone

mode.Potential source for exploitation.Most efficient when operates in integrated mode.

Advantages of solar Energy

USES OF SOLAR ENERGY• Heaters Green houses

• Cars water pumps• Lights Desalination • Satellites Chilling• Dryers Solar ponds• Calculators Thermal Commercial use

• On an office building , roof areas can be covered with solar panels .

• Remote buildings such as schools , communities can make use of solar energy.

• In developing countries , this solar panels are very much useful.

• Even on the highways , for every five kilometres ,solar telephones are used.
