Overview of the Solar Energy sector in India
Author: India Reports
India has a vast supply of green energy resources, and has a significant program for deploying these resources. An exclusive ministry for renewable energy called Ministry of Non-conventional Energy Sources later renamed as Ministry of New and Renewable Energy (MNES) has also been set up.
According to the recent report on Renewable Energy in India from India-Reports the Renewable Energy market in India is pegged at US0 million, growing at 15% per annum. The Government’s renewable energy target by 2030 is 200 gigawatts, estimated to require US0 billion in capital investment. Currently, 3.5% of installed capacity is in the renewable sector, producing 3700 MW. Renewable energy is projected to produce 10,000 MW by 2012.
Solar Energy in India
Solar Energy is one of the fastest growing sectors of the Renewable Energy Sector in India. The estimated potential of Solar Energy in India is 5000 trillion units per year.
Private investors have invested US billion to build plants to make photovoltaic cells. The Government of India has announced incentives to manufacture solar cells and panels.
Most of the expansion in India is to primarily cater to global demand for solar energy infrastructure. The demand in India for solar energy generation infrastructure is growing at 25% per annum.
The solar energy industry requires additional incentives by the government to encourage solar power adoption to give an added boost to the sector in India.
Some of the major trends in Solar Energy Generation in India are:
1. Solar tracking mechanisms – collectors or parabolic dishes that track the movement of the sun and move accordingly
2. High efficiency photovoltaic cells – With an efficiency of 13% with single crystal silicon, no moving parts and easy maintenance
3. Cells with concentrators to become effective and deliver same results with lower intensity of sunlight or fewer cells
The major constraint to Solar Energy Generation in India is the high initial costs for setting up.
The solar energy industry requires additional incentives by the government to encourage solar power adoption to give an added boost to the sector in India.

How do places with wind and solar energy sustain their power?
Some places rely on solar and wind energy right? To power their homes and such. How do they use energy in the night or when there is no wind? Do they have something that stores the energy like a big battery or something?
I have to “make” a green city and it will use renewable energy source including solar and wind energy. How would I make the wind and solar energy sustainable and not have shortages of power?
How is solar energy harnessed for human benefit?
Please help w/ these questions..And provide Sources/References !
- Type of energy transformations that take place in harnessing the solar energy.
- efficiency of the (solar) energy transformations
- The amount of energy obtained from solar energy?
Thank you !
How does the solar energy is stored in a battery?
How does the solar battery charged using solar panels?What is the mechanism that converts solar energy in to electrical energy? How can a car be run on solar energy?what could be its maximum speed?
How to estimate Solar energy on certain direction pointed surface?
If I mount a flat surface which points to certain constant direction. At certain place of the world. I now need to estimate the maximum amount of Solar radiation energy which this surface can get during certain time.
Is there a PC program or an algorithm that can make this estimate for me?
The actual problem.
I need to know how much maximum energy can I get during a year, if I put solar cells or solar collectors on my house tilted roof?
Is there anyone who can somehow help me?
Thank you in advance.
How would you use solar energy most efficiently in your home or school?
What time of day tends to be best for charging a solar cell? How does the angle of incidence of light affect the energy output of a solar cell? How is digital multimeter used to measure how much voltage is being produced by the solar cell?
Try looking here: http://rredc.nrel.gov/solar/old_data/nsrdb/redbook/atlas/
That’s the National Renewable Energy Labs site, and will give you insolation (amount of sun) for your area. If you have an ideal location and roof, you would choose, Average, Annual, Flat plate tilted south at latitude. Then a map will come up. This map takes into account weather conditions, too, because it is derived from actual measured data. Thus, a dry, cloudless location such as Phoenix shows more sun than a place with more clouds like Honolulu.
Let’s say the map says you get 5 hours equivalent sun per day. The word “equivalent” is important, because it factors in that morning and evening sun are weaker than noonday. The number you get means the equivalent of direct, noonday sun for 5 hours, even though it may be 12 hours from sunrise to sunset. And it’s an annual average, so you will get more in the summer, less in the winter. Ok, so you take that figure, say 5 hours, and multiply it my the size of your array in watts, and multiply it by 365, the number of days in a year.
Example:
5 hours/day X 3 kW array X 365 days/year = 5475 kWh/year.
If you want a more complex calculation, you can try http://www.pvwatts.org/ , and take into account exact tilt and orientation of your roof.
The mechanism used to convert solar energy is called a photovoltaic cell.
Just use an electric car, with batteries being charged by a solar panel on the roof or at a filling port (similar to a gas station).
Solar cells are built of a mostly silicon compound, which leaves some atoms with loose electrons. These electrons are knocked free by the energy of the sun and, if attached to a circuit, will charge the battery like any AC charger.
A car can be run very simply
The fastest solar car I know of is the Nuna 2 (105 mph)
Hope this helps
I saw a link to Earth4Energy above. Earth4Energy is a scam, so beware. I wrote it up in my hall of shame at http://www.nlcpr.com/Deceptions6.html
The two common collection methods are photoelectric cells (solar cells) that make electricity, and solar heat collectors. Heat collectors are usually either the flat plate variety, or evacuated tube collectors. Wikipedia is a good place to read about how solar cells work. see http://en.wikipedia.org/wiki/Photoelectric_effect
I have a few pictures posted at http://www.nlcpr.com/SolarInsolation.html that you will find interesting. The houses are from the Solar Decathlon at Washington DC.
The amount of energy is dependent on where you are on Earth and the time of year. Most governments publish solar insolation maps you can use. I will post links below. For Canada use the link for natural resources Canada. For the USA use NREL (National Renewable Energy Lab). NASA has maps that cover the entire Earth. If you know the annual solar energy per square meter in your area, you can multiply it by the efficiency of the collector to get a feel for how much energy you can extract.
The efficiency of a evacuated tube collector is complex to calculate, but you can get practical equations from Institute SPF – they are European and respected. SPF tests both flat plate and evacuated tube models. I have a graph on my web site that shows the efficiency of Apricus brand tubes. Efficiency will likely be somewhere around 50%. If course, it depends on how cold it is outside. There is also space between each tube, so be careful with the math.
So, in summary: Get the total amount of energy from a solar insolation map (NASA, NREL or NRC). Get solar collector (heat) efficiencies from Institute SPF. Get the solar panel efficiencies from a reputable manufacturer like BP (British Petroleum). Use Wikipedia for links to the theory.
Wind energy is indirect solar energy if you want to enlarge the scope of your studies.
If you need a specific resource, use the contact form on my web site and if I can find what you need, I will post it on my links page for everyone.
Have fun with your project/assignment.
Small places, like a remote house or an island, might have batteries. A large place, like a city, would be connected to a “Grid”, or electrical energy transmission system. If the wind stopped blowing, deep in the night, they would pull energy off the grid, from a nuclear plant, or coal-burning generation station, or hydroelectric project many miles away. A town on an island might have a large diesel generator.
