How and Why Solar Energy (PV Solar) scores over other Renew Techs?


There is a lot of interest generated lately in Green Energy or Renewable Energy Sources. This interest may seem sudden but in fact the interest had always been there just that it is becoming visible now. Everyone was keen to tap Solar Energy - in someway or the other to make use of the same as part of day-to-day activities. For all practical purposes one can consider The Sun to be practically infinite source of energy thereby drawing a lot of attention.

Renewable Energy Sources are especially important in the Indian context because of large-scale dependence on Fossil Fuel especially Coal which accounts for nearly 60% of power generation in India. Although there are a variety of renewable power options Solar Energy will contribute maximum to India Growth Story.

Challenges of depletion of fossil fuels, environmental hazards, increasing power demand, infrastructural issues in transmission and distribution etc. are quite well-known. With a present peak power deficit of 10% it is estimated that it would rise to nearly double in the next 5 years unless stringent and concrete measures are taken to meet the power demand. Renewable Energy Sources such as Solar, Wind, Hydro, Tidal, Geothermal play an important role. Any Country must ideally look at its strength in terms of Geographic conditions and allocate suitable budget for the right mix of power portfolio which should have maximum priority to the most easily available and feasible option.

In the Indian context Solar Energy is the leader in terms of Source of Renewable Energy and it offers several advantages in a growing economy. Various factors that work in favor of PV Solar are

  • PV Solar is the only power generator which can deliver power at ZERO operational cost / running cost. No other renewable technology can claim this.
  • Excellent Solar Radiation across the Country ensures feasibility of PV Solar across the Geography.
  • With 25-30 years of critical component life (Photo Voltaic Modules) it ensures a long-term, reliable and sustainable power solution.
  • Generation-Load proximity ensures minimal losses - a very important aspect in a Country which has one of the worst ATC (T&D) losses in the range of 25-30%.
  • PV Solar is truly environmentally friendly with a Energy Payback of 2-5 years which no other renewable energy technology can claim.
  • PV Solar can be installed closed to human habitat as it does not cause any health hazard.
  • PV Solar also has an advantage over Solar Thermal Power - in which it does not require water to operate.
And many more such advantages...


Industries should ideally be the first movers as they can benefit immensely from the units saved as they are charged a higher power tariff. In fact several leading Industries have already taken the first step in this direction by carrying out feasibility study at their sites and results have been phenomenal. On an average any industry can reduce around 10% of its power consumption and also benefit from several Government subsidies under JNNSM.

Apart from general awareness on the subject the problem with PV Solar is Myths surrounding it. However with the percolation of appropriate information we expect that PV Solar will become the solution of choice at not only Industrial or Utility level but also at household level.

What is Solar Energy? Solar Energy Facts

Solar Energy is an increasingly popular term especially in the Indian region after a lot of interest has been generated in this regards. This has been true because of various factors playing a key role especially Power deficit driving interest and also suitability of using Solar Energy across India.

This post attempts to look at a Few Facts about Solar Energy and they are -
  1. Solar Energy i.e. the Energy received from The Sun is the only source of Energy which provides 2 Sources - Light Energy and Thermal / Heat Energy.
  2. Solar Thermal Applications have been in use for quite sometime in the Indian context especially because of increased awareness and Government subsidies. Primarily Solar Thermal Applications include Water Heating - at Industrial & Domestic level, Drying Applications, Process preheating in Industries etc.
  3. Recently Solar Thermal is also used for generating power through super-heated steam.
  4. Light Energy of The Sun is primarily used for day-time lighting applications and also power generation.
  5. Power generation by using Light Energy of The Sun is done through Photo Voltaic Solar Panels. PV Solar panels are basically solid state electrical devices which generate electrical power when Sunlight is incident on them - either directly or diffused.
  6. India has a peak deficit of about 10% (as per CERC) and even though there are aggressive plans to add Power Generation capacity it may not suffice due to ever-increasing demand for Power and hence Solar Power Generation is being considered as the most suitable option considering geographic conditions.
  7. India has one of the worst T&D (aka ATC Losses) of around 30%. Solar Power can be effectively utilized for decentralized PV Solar Power Projects wherein losses are negligible or zero especially because of generation-load proximity.
  8. Solar Energy is gaining lot of interest especially because of excellent radiation (also known as Solar Insolation) across the Country - which can be seen in the Solar Radiation Map.
  9. PV Solar applications at a small scale have been in use for long to power small devices - watches, calculators, lanterns etc.
  10. PV Solar as Power Generators is a relatively new but an emerging concept in India. Globally PV Solar Power Projects have been installed at various levels with Germany leading the PV Solar installation capacity with an installed capacity of 17,000 MW.
  11. Another advantage of PV Solar is that it has nearly ZERO running or operational cost associated with it  - which no other technology can offer.
  12. Government initiatives (at Central and State level) have been very encouraging at various levels. It is estimated that PV Solar Power capacity which is around 140 MW (as on Nov 2011) will be 3000 MW++ by 2013 - a quantum leap !
  13. Grid parity is a term to judge a technology's commercial aspect with respect to other technologies. In case of PV Solar price parity has been reached if compared with DG Sets and hence DG Sets prove to be an ideal candidate for replacement by PV Solar.
  14. The primary reason why PV Solar is not able to pick up is because of lack of awareness and various Myths about PV Solar. If appropriate information is communicated then PV Solar will certainly be the Power of choice.
Solar Energy FAQs - is another one of our posts which discusses about the most commonly and frequently asked questions on Solar Energy. It looks at more of the queries asked by individuals interested in knowing more about Solar Energy.

Ideally PV Solar Power should be the way forward and the only impeding reason for its growth is lack of awareness regarding the benefit that it offers in addition to the support by various Central and State Governments. Industries should be the first one to utilize PV Solar Power as they have a huge un-utilized rooftops and adjoining land areas which could be effectively utilized for installation of PV Solar Panels. In fact we are already engaged with Industry Leaders and providing them Expert Advisory and Consultancy on how they could move in that direction.

The response has been phenomenal with several key players already considering the Projects that have been identified at their locations. The most attractive part is the Government offers excellent benefit for not only grid-feed projects but also captive consumption projects that an Industry would like to opt for. These incentives also protect the Industries from ever-rising power prices.

Solar Energy - Today & Tomorrow !



Solar Energy - Today & Tomorrow !

Utilization of Solar Energy dates back to several decades when technology advancements proved utilization of Solar Energy could be done for heating purposes, power small devices (watches, calculators etc.) and certainly powering remote satellites during their long journey away from any power stations.


More popularly Solar Energy is presently used for water heating - both at domestic and industrial level, drying especially at Industrial level, use of PV Solar applications such as Street lighting, Signals, Lanterns etc. However PV Solar Power Plants - although not a new concept - is a relatively new and emerging concept in India. The technology is well-established globally with Germany (yes Germany) with not so good radiation and Sun availability is already a global leader with installations of about 17 GW.


Antagonist of Solar Energy argue that it is a developing technology, expensive, can only work during the daytime etc. Looking at it the other way - if not PV Solar for power then what? If not Solar Energy for India - then what? Coal is already facing an issue with respect to supply and pricing. With nearly 65% Power generation from Coal does it justify relying on it as a major power source for the long term? Is nuclear the answer? Well it would have been but after not after what happened in Japan in March 2011. The world is giving second thoughts to Nuclear Power Plants with several Countries planning to go Nuclear-free.


The writing on the wall is clear - the way forward for any Country is a Portfolio of Green Energy Sources for Power Generation to supplement the fossil fuels. Depending on the Geographical conditions and further detailing stress should be laid on a particular green technology and should be suitably combined with other green technologies. This does not mean that Renewtechs will completely replace Fossil Fuels - atleast not in the foreseeable future. What it definitely means is that Renewtechs can be and should suitably included as part of the power generation portfolio of a Country based on its geographics and technology viability. For instance Denmark has effectively utilized its Wind Power generation capacity and has pioneered the same. Today it boasts of leading Wind Turbine manufacturers and a well-established portfolio led by Wind power generation.


Similar to a Country a Company or a Plant should also look at developing an effective power portfolio to supplement grid power or fossil fuel captive power. The benefits of doing so are enormous in monetary terms as well as for long-term sustainability. In the Indian context PV Solar offers a Very Good Solution both in terms of Technical Feasibility and Commercial Viability.


In case of India it is no surprise that Solar Energy will prove to be the most utilized source of Green Power. Why? Well reasons are many but to list down the few important ones :
  • Excellent Solar Radiation across the Country 
  • Wind is found only in some pockets - yet India is among Top 5 Wind Power Generation. With the excellent potential in Solar Energy - the capacity installation or growth in this upcoming field is anyones guess.
  • One of the Best Incentive & Subsidy programme under JNNSM to encourage use of Solar Power. This is also to counter the argument that investing in Solar Energy does not result in sufficient payback. Not that Solar energy would need a subsidy scheme all along but any new technology (including Wind) needs an apt policy to support its entry and encourage its use among the masses.
  • Solar scores well above Wind Power (Solar vs Wind Comparison can be requested) and hence will prove beneficial at all levels - for residential use, industrial use, community use, utility use. In fact PV Solar also scores above other renewable technologies.
  • Peak deficit usually occurs in the day - time when most of the Commercial activities take place. Solar presents a very good answer to this problem.
  • It will prove to be the single-most important source of decentralized power system thereby overcoming issues related to infrastructure, rural electrification theft, T&D (or ATC Losses) etc.
  • It can be used closer to human habitat and is highly modular and scaleable - with ZERO maintenance - which no other Renewtech can offer.
The Government (both Central and various States) having realized the benefits of Photo Voltaic Solar have declared various commercial subsidies and incentives to encourage the use of Solar Power. At the National Level JNNSM ensures good subsidy and incentive at every level for small PV power generators, medium scale projects and utility scale projects. Additionally various States - Rajasthan, Gujarat, M.P., Karnataka, T.N.  have also declared their individual Solar policies.


For long Fossil Fuels especially Petrol, Diesel and Kerosene have been heavily subsidized as a populist approach. There is a tremendous shift now - due to Global Pressure and Internal Demand - that a greener approach is the way forward. Owing to this the Government will continue to reduce the subsidy on Fossil Fuels and divert the funds towards Green Solutions - especially Solar Energy. Further rising of fossil fuels is not ruled out and once Coal prices become market-driven then the already high power prices will sky-rocket.


Rather than reaching a point of no-return where Coal has reached exhaustion stage there is an urgent need to look at Alternative Sources of Energy. It is rightly mentioned that alternative sources of energy are no longer alternative. Perhaps Green Energy do have the potential of becoming the mainstream sources of energy if not in the near future then in the coming decades. What needs to be seen is  the best portfolio for India and Indian Industries and Solar Energy will most certainly play the most significant role in the capacity building.

Why Solar Energy will Play a Crucial Role in India Growth Story?


Why Solar Energy will play a Crucial role in India Growth Story?

The Sun is rightly worshipped as God across the Globe mainly in India, Egypt, China and parts of Africa. The Sun is the Supreme source of Energy. It is therefore no surprise that mankind had already been using Solar Energy but now seizing the Solar Opportunity for converting it into more useable form such as Electrical Energy.

India has been on consistent growth path especially after the reforms that began in early 1990s. Power plays a critical role for growth of any Nation. All the 5 year plans have put special thrust on Power Generation and the 12th 5 year plan (2012-2017) will lay a special emphasis on the same. With present installation of nearly 1.7 Lakh MW it is estimated that target addition would be of nearly 1 Lakh MW for the upcoming 5 year plan to sustain 8-10% growth. 

Coal has always been and will continue to be primary fuel for Power Generation. Hence conventional coal-fired Power Plants will have a significant portion of the slated power targets. However one point worth mentioning here is that so far open cast mining was carried out for Coal recovery – which was a cheaper and an easier option. Deep mining will now be carried out on a large-scale increasing the cost of Coal and at the same time resulting in availability issues. Ageing of older Power Plants and mushrooming of newer ones are other concerns. Rising concerns about Carbon emission, depleting reserves and quality of Indian Coal, price of imported Coal will be other concerns in this sector. Some interesting Energy related facts and figures can be found on our website.

Renewable Energy Sources such as The Sun, Wind, Biomass, Hydro offer a good solution in such a scenario. India is already among the top Global Wind power generators. However Wind does have associated problems of unpredictability and can only be installed in specific areas offering good wind. Biomass offers a good option for areas rich in agro waste such as Haryana, Punjab, M.P. etc. Hydroelectric power stations are good but are highly location specific and impact the environment caused by displacement. Wind-Solar hybrid solution could be worked out for smaller loads but may not be practical for Utility Scale Projects.

In such a scenario The Sun will prove to be Cleanest and most Practical source of Energy of today and tomorrow. The points in favor of Solar Energy in India are –
  • High Solar Insolation / Radiation across the Country (India Solar Radiation Map)
  • Perfect Answer to Peak Demand (day time)
  • Energy present in 2 forms – Heat & Light and can be simultaneously used for a variety of applications.
  • Available in huge quantity
  • Highly predictable and hence easier to tap
  • Truly green with no pollution or emissions
Heat Energy of The Sun could be used for heating purpose in a variety of Industrial processes and utilities. It can also be used for Electricity generation by generating superheated steam to run turbines.

On the other hand Light Energy of The Sun could be directly used for Electricity generation through Photo Voltaic (PV) Modules. PV offers several benefits over Thermal Systems in addition to the general benefits of Solar Energy mentioned above. They are :
  1. PV  can be used for smaller power generation (in Watt or kW) and upto Utility Scale (several MWs).
  2. Has an excellent trouble-free life of 20-25 years with appropriate manufacturer warranty on products and engineering companies performance warranty on output i.e. units generated.
  3. Absence of moving parts (except optional trackers) makes the system highly reliable and practically maintenance-free.
  4. Modularity ensures addressing various power needs and load types.
  5. Scaling up at any time is very convenient and can be customized to suit the power requirement and available budget in a phased manner.
  6. Is absolutely environment-friendly and non-hazardous and hence can be used around human habitats and on domestic rooftops as well.
  7. Ideal solution for decentralized power generation in remote areas as it does not need any expertise to run or maintain.
  8. For utility scale projects it can be installed on arid and barren lands and putting the land to good use.
  9. Water is another scarce resource. PV Operations (unlike Solar Thermal) do not need water to run its operations.
  10. Can replace DG Sets as cost of generation would be nearly the same – without causing pollution and without risking future price rise in fuel.
Antagonists of PV argue that the costs for PV are on the higher side. The technology cost is indeed high but has come down drastically (subscribe to our newsletter to keep yourself posted) in the recent past. It was earlier estimated that the Grid Parity (PV cost of generation equaling the price of grid power) would be achieved by 2017. However with rapid increase in cost of fossil fuels and significant drop in PV Module prices Grid parity would be achieved much earlier perhaps by 2013-14. Nearly 10% of power generation in India is by diesel and interestingly PV Power generation has already achieved parity with diesel power generation. The recent drop in PV Module prices has also resulted in shorter financial payback of 3-5 years.

Energy Payback is a term used by Green protagonists to estimate the “Greenness” of a system or a solution. It indicates time taken by a system or a solution or a product to operate and to recover the energy (and CO2 emissions) that was spent (or emitted) on manufacturing it. According to studies the Energy Payback for PV varies from 2-5 years and has expected life of 20-25 years thereby indicating feasible Energy Payback and hence justifying its use.

India faces a peculiar problem of fueling growth without causing harm to the environment – unlike Western Countries who developed without worrying about environmental effects. It is thus imperative for India Growth story to set an example of “Green Power Growth”. This would require lot of emphasis on use of Solar Energy by the Government bodies, Industrial Bodies, Individual Industries, Corporate Houses etc. Government has taken the first crucial step by announcing Jawaharlal Nehru National Solar Mission and announced various capital subsidies, preferential feed-in tariff, low interest loans, discounted rates for land procurement etc. Emergence of this sector would also see an emergence of good number of Entrepreneurs and skilled workforce for sustained growth.

Solar Energy can be considered infinite for all practical purposes. Its availability in India, Green Nature and Easy applicability makes it ideal for use at all levels of power requirements i.e from domestic level to community level to utility scale.

PV Solar - Top 5 Myths BUSTED !

                                        PV Solar - Top 5 Myths BUSTED !


Introduction
India is blessed with enough Solar Energy to wipe out all the power problems of our Country. Solar Energy could be used to directly generate power in Photo Voltaic Solar Power Plants, Produce Steam to generate power in Solar Thermal Power Plants, used in small to medium size off-grid PV Solar projects in rural areas etc.

Jawaharal Nehru National Solar Mission (JNNSM) aims at positioning India as a Global Leader in Solar Energy with a target of 20,000 MW of Solar Energy by 2022 in 3 phases. This is a huge number considering the fact that the present count stands at less than 20 MW of Solar Installation. In such a scenario percolation of right information to the masses is a must. In this Whitepaper on Solar Energy Scenario in India we attempt to bust the 5 myths about Solar Energy. Interesting facts about PV Solar  Power and Energy can be found on  where in a video presentation on Energy Conservation and Solar Energy can be found on our Homepage.

Myth # 1 : Generating Power from Solar Energy is very expensive
PV Solar Cells contribute to nearly 75% of the project cost. Other costs include Invertors, Mounting Structure, Cabling etc. However PV Solar Prices have come down drastically in the last few years and are now at nearly 50% discount. To top it all the incentives provided by the Government under JNNSM makes the project completely feasible and financially viable.

70% of Power Generation in India is through Coal based Thermal Power Plants and this figure would continue to rise. It is also a fact that a PV Solar Plant costs nearly 3.5x the cost associated with Coal based TPPs. However with Government incentives the project becomes feasible as the Government pays nearly 4 times per Unit for power generated through PV Solar as against the power generated through conventional means. Also the time taken to setup a PV Solar Project and the maintenance cost is a fraction of respective figures for similar capacity conventional project.
Another point worth mentioning is that even in the absence of financial support a PV Solar Power Plant can typically pay back for itself in 6-7 years. PV Solar Plant life is nearly 25-30 years and hence it completely justifies the initial investment. This is more so as a PV Solar Power Plant requires nearly zero maintenance.

All in all PV Solar Project is not expensive if considered in totality i.e. –
Ø  Significant reduction in PV Cell prices.
Ø  High output over a period of 25-30 years with manufacturer’s warranty and guarantee for the same.
Ø  Nearly Zero Maintenance as there is no moving part in a basic PV Solar setup.
Ø  Government incentives to encourage the use of Solar Energy in our Solar rich Country.
Ø  Rising power prices because of depletion of coal reserves and rising cost of coal.
Hence except for initial investment Solar Energy is not really expensive.
Myth # 2 : Solar Power Plants requires lot of space and maintenance
PV Solar can use variety of Technology mainly depending on the cell type. The 2 most popular technologies are Thin film and Poly Crystalline. Thin film is lesser efficient and hence requires more space i.e. nearly about 7 Acres per MW and also costs lesser than Poly Crystalline projects.

Poly Crystalline requires nearly 3.5-4 Acres per MW has higher efficiency and costs a little more than Thin film.

So depending on specific requirements of a project and tradeoff between cost and efficiency could lead to best combination of technology. Moreover the space can be in isolated areas where land cost can be really low or highly subsidized by Government for long lease as well. If it is on a rooftop of an existing Building or Industry or Facility – the space cost is NIL.

Moreover there is no restriction on placement on PV Solar Cells or Farms next to each other. In fact modularity is one significant quality of PV Power Generation. Compare to this a wind-farm has restriction of not having wind mills in proximity to an existing one., typically several acres per MW.

Basic PV Solar Power Plant consists of South-oriented static mounting structure and has no moving parts. The only maintenance cost that would be associated with such a setup would be occasional cleaning (which could be automated) by unskilled laborers maybe once a week or once a month.

Myth # 3 : Efficiency of Solar Cells is still Low and will get better with time
Certainly the efficiency of Solar Cells would improve over time with progress in Technology and R&D. This could be compared to any other Product such as Cell phones or Cars. They have evolved over time with respect to efficiency, technology, comfort etc. But that does not mean that we wait to buy the most efficient product.

Solar Cell technology is mature and the panels are of high quality with 95% value addition done outside India. What is at stake now, is not the efficiency of panels, but the price per generated kilowatt-hour. It is no longer about the type of motor in a car, but about how much fuel the motor consumes per mile.

There will still be new types of solar panels developed, with better efficiency, but the real success of solar energy in the future will lie in large-scale production matters and growth of the global market. A low purchasing price for a solar panel will be the determining factor for low-cost generation of solar energy for the consumer.

What one needs to understand that similar to the fact that the Pentium 1 users did not wait for Pentium 2 to be launched and consecutive newer technologies., the same thing applies to Solar Industry as well. Moreover the output i.e. units generated from a PV Solar Power Plant is very much comparable to other green technologies depending on location. A wind farm typically generates 20-25 lakh Units per MW and it decreases over a period of time and the deterioration to 16-17 lakh Units is very fast. However a PV Solar Plant will continue to generate the guaranteed Units for a very long time. The investor is protected with appropriate warranty and guarantee of output for longer periods such as 15 years / 20 years / 25 years.

Myth # 4 : Solar Panels have a high carbon footprint
Solar panels are usually made from silicon. Silicon is found in sand, one of the most widespread natural elements on earth. The ovens used to transform the sand into silicon use a lot of energy - that is true. But the payback time for the energy used to produce a solar panel is only 1 to 2 years. This means that in this time the panel generates the total amount of energy that has been used for its complete production - thanks to the free energy of The Sun.

All power generated after the payback time is pure green profit, while solar panels can last 25 to 30 years! Other sources of energy have much longer payback times. Specifically, nuclear power plants have extremely long payback times, so long that it is questionable whether all the power that was generated during their lifetime is enough to pay for the energy used to build and disassemble them.
 
Compared to any other technology (including Thermal Power Plants) the Carbon footprint of PV Solar Panels is much lesser.

Myth # 5 : Solar Power Generation cannot work in all locations
The world’s biggest market for solar energy is Germany, a country not particularly blessed with long days full of sunshine, but a country with a smart government nonetheless. In the summer, more than 10% of the household electricity in the south of Germany is generated by solar panels.

In the Indian context almost all parts of India are suitable for using Solar Energy – considering very good Sunshine in most part of the Country and nearly 250+ Sunny days per annum. The RoI depends on the location and for instance would be better for some parts of Rajasthan than for some parts of Gujarat. However that does not particularly rule out any area as not feasible.

Technically there are 2 important aspects for consideration while conducting feasibility i.e. Direct Normal Irradiance (DNI) and Global Horizontal Irradiance (GHI). The units used are kWh/m2/day and DNI for a good area could be around 7 with an average area around 4.0-4.5 with good number of Sunny days.
DNI figures for most part of Germany is much lower than 3.5 and much lesser Sunny days – yet it is foremost in using Solar Energy – then why not any other location in India?


We offer End-to-End Services in PV Solar Power Projects.

Conclusion
Rising power costs by conventional means and deteriorating environment has forced mankind to look at renewable sources of Energy. Of all the renewable sources The Sun is the ultimate source of energy and the cleanest form as well.

Usage of PV Solar has been in existence for nearly 4 decades now but commercial power generation has become popular in the last 2 decades.  Considering the fact that PV Power Generation could be done on rooftops without causing any hazard – it would be used on rooftops to generate power for individual homes as well as Industries. Even off-grid solutions are gaining popularity in rural areas. The way Solar Mission is gaining momentum it is estimated that power from PV Solar will achieve grid parity by 2017. This means that power from PV Solar will be at par from the power received through utility. This also means that for a particular installation.,  beyond this timeline power from PV Solar will remain nearly constant but utility power will continue to rise. Thus PV Solar power generation would become cheaper than utility power !

Due to various benefits – commercial and environmental – associated with PV Solar there is no doubt that it will gain popularity in India sooner than later. The early movers can make the most of it by availing of Subsidies, Incentives and Renewable Energy Certificates (RECs) etc. making investment in PV Solar highly attractive.

Why Solar Energy is the way forward in India?


India faces a huge power shortage (slated to be in the range of 70 Million Units). Nearly 70% of power generation in the Country is through Coal based Thermal Power Plants. Although the Country has Coal reserves for nearly 60-70 years., but it is depleting faster with the advent of new projects and coal linkage agreements.
Moreover the Coal prices in India are expected to rise steeply as they have been deliberately kept lower than International market prices.

The challenges in the present Power Generation are quite a few :
Ø  Gestation period for new Thermal Power Plants (5-10 years depending on the plant size).
Ø  Coal Availability and Logistics Issues (55% Power is from Coal TPP).
Ø  Transmission & Distribution Losses (highest across the Globe).
Ø  Rural Electrification Issues (Cost, Feasibility etc.)
Ø  Environmental Clearances and Social Issues (land availability).
Ø  Emissions and Pollution related Issues.

The TPPs require another scarce natural resource i.e. water in huge quantity for their operations. Other day-to-day issues associated with TPPs include huge maintenance costs and manpower requirement.

In such a Scenario PV Solar offers a relief from the above problems. India is blessed with enough Solar Energy to wipe out the Power Problem and also address the future Energy needs of the Country. Solar Energy Utilization has gained further prominence after recent Fukushima Nuclear Power Plant Problem. In fact Germany has declared to go Nuclear Free by 2022. This is no surprise considering that nearly 15% of Power during Summer is from household rooftops in Germany.
Solar Energy is not only truly green in nature but is also hazard-free. In the Indian context it is more beneficial as it can answer most of the power related problems – much quicker and better than conventional Power Plants or even Nuclear Power Plants.

[Suggested Read - Is Solar Energy really affordable?]

A few facts about PV Solar Power Plants :
ü  Require a fraction of time to be setup as compared to conventional Thermal Power Plants.
ü  Utility-scale Project could be set up in remote areas in non-arid lands and water is not required.
ü  Small-scale Project could be installed on rooftops for captive consumption.
ü  Off-grid Project could be set up for specific villages (thereby saving costs on expensive grid-lines).
ü  Does not require any raw material to operate as it only needs Sun Light.
ü  The range could be as small as 1 kW to 50 MW and more.
ü  Require NIL or Minimum maintenance which could be carried out by unskilled labourers or villagers (incase of off-grid solutions).
ü  Is a completely green solution with no emissions and hence safe for installation in human habitats as well.
Some more interesting aspects are highlighted in our post on Why PV Solar scores over other Renewtechs? 

Most parts of India are worthy and feasible for PV Solar Power Plants due to good availability of Sun Light throughout the year. Moreover with the Government Subsidies and Incentives under JNNSM make the projects completely viable. Some of the Government Schemes are :

·         Preferential Tariff :: State DISCOMs purchase power from Solar Energy at a much higher rate in the form of Long-term PPA for 25 years.
·         Renewable Energy Certificate :: RECs are market tradeable Instruments which enable a Solar Power Investor to recover the investments by selling RECs in the Power Exchanges.
·         Capital Subsidy :: 30% Capital Subsidy is available for off-grid projects.
