This analysis based report is done for the readers of my previous report 1MW Utility Scale SPV Power Plant, mainly for the readers from South region of INDIA as they are asking repeatedly about the probability and feasibility-technical & Financial-of a SPV power plant in their region. At the same time its not possible for me to design a report for each and every state from South India, so I took Chennai city. Also the previous report was not so detail, was very basic and meant to the readers who want to get an overview on how a utility scale power plant works. Now, in this report, I discuss about in depth. From panels selection to CB sizing all are presented in very detail. Hope, this time you get a strong knowledge on designing and estimation of 1MW solar PV power plant. Unlike the previous report, the financial aspect discussed at the end of the paper. In this paper, the financial assessment has done in very detail and considering the current scenario of SPV market including the cost of solar PV modules, inverters cost, cable, transformer etc. prices and the funding, interest rate..

DisclaimerThe presented data here are NOT TAKEN from any copyright materials and not showing under my name. The meteo data collected from NASA website and NREL database which is free over the internet. Designing of PV system is totally based on the practical experience of the author.Assumption & Consideration

Shading consideration: No shading has been considered at the site during the calculation design. So it is advised that at the time of execution, please check whether there is any kind of obstacle in the site which may cause partial/full shading on PV strings and/or PV array. If the shading occurs, then the estimated power generation will not match the actual power generated.Load Factor: It is assumed that the produced power from the PV plant will be fed to the local utility grid. So, while designing the system, no unbalanced load considered in 3 phase configuration.Meteo data: The calculation based on the meteo data collected from NASA website which is very reliable. Now, based on the co-ordinates the values have been presented in this report. So, total design is based on this data. For a different location (coordinates), the system design will differ. It is advised not to copy and implement the design without consulting the author or any certified PV professional because this design estimation is valid only for a particular site.

Site consideration: this design has been done by considering the PV modules & array will beground-mounted and the site-elevation angle taken 30 .Cost Estimation: 1MW Solar PV power plant cost estimation has done considering the current PV market scenario (Sept-Dec 2013), so after few months the cost may vary according the market.CAD design & layout: I have not uploaded/attached the CAD design. If anybody interested in setting up the plant then only contact at the given e-mail ids to get the design file.Transmission & wheeling losses: Here, in this report, while doing the technical assessment, the distance from nearest substation to the 1MW solar PV power plant taken within 1.5 KM and so the wheeling losses considered as 3% of total power transmission. And in the financial assessment, no wheeling charges have been considered.Design Criteria: While designing & estimating the technical components & solutions, all the required/applicable standard design codes have been considered. Mainly the IEC (International Electrotechnical Commission) Codes, IS codes from BIS have been considered thoroughly.

Solar power in India

India'ssolar resourceIndiais densely populated and has high solarinsolation, an ideal combination for usingsolar power in India. Moreover, it's other energy resources are relatively scarce. In the solar energy sector, some large projects have been proposed, and a 35,000km2(14,000sqmi) area of theThar Deserthas been set aside for solar power projects, sufficient to generate 700 to 2,100GW.In July 2009, India unveiled aUS$19 billion plan to produce 20 GW of solar power by 2020.Under the plan, the use of solar-powered equipment and applications would be made compulsory in all government buildings, as well as hospitals and hotels.[2]In January 2015, the Indian government significantly expanded its solar plans, targetingUS$100 billion of investment and 100 GW of solar capacity by 2022According to a 2011 report by BRIDGE TO INDIA and GTM Research, India is facing a perfect storm of factors that will drive solar photovoltaic (PV) adoption at a "furious pace over the next five years and beyond". The falling prices of PV panels, mostly from China but also from the U.S., has coincided with the growing cost of grid power in India. Government support and ample solar resources have also helped to increase solar adoption, but perhaps the biggest factor has been need. India, "as a growing economy with a surging middle class, is now facing a severe electricity deficit that often runs between 10% and 13% of daily need".India is planning to install the World's largest Solar Power Plant with 4,000 MW Capacity nearSambhar LakeinRajasthan. There are various factors that we need to consider before investing into a solar power plant. A lot of enthusiasm has been seen among people about the use of Solar Energy as a substitute of conventional sources of energy. However, currently, with the power subsidies in India, solar works economical only in those areas that are using diesel generators as a primary source of electricity. The entire payback is made in 23 years. Solar system for petrol pumps is a leading example of such an application. IOCL is leading the race for solarization of petrol pumps with aggressive targets. Solar applications for petrol pumps by RelyOn Solar has been installed in more than 150 IOCL petrol pumps across India and now other oil companies are also looking to solarize their ROs. Solar installations for commercial buildings, where the electricity rates are higher, are also proving to be a game changer for the owners of IT companies.On 16 May 2011, Indias first 5 MW of installed capacity solar power project was registered under the Clean Development Mechanism. The project is in Sivagangai Village,Sivagangadistrict,Tamil Nadu. Current statusInstalled solar PV

With about 300 clear, sunny days in a year, India's theoreticalsolar powerreception, on only its land area, is about 5,000 trillionkilowatt-hours(kWh) per year (or 5EWh/yr).The daily average solar energy incident over India varies from 4 to 7 kWh/m2with about 1,5002,000 sunshine hours per year (depending upon location), which is far more than current total energy consumption. For example, assuming the efficiency of PV modules were as low as 10%, this would still be a thousand times greater than the domestic electricity demand projected for 2015. The amount of solar energy produced in India in 2007 was less than 1% of the total energy demand.The grid-connected solar power as of December 2010 was merely 10MW Government-funded solar energy in India only accounted for approximately 6.4MW-yrs of power as of 2005.However, India is ranked number one in terms of solar energy production per watt installed, with an insolation of 1,700 to 1,900 kilowatt hours per kilowatt peak (kWh/KWp).25.1MW was added in 2010 and 468.3MW in 2011.By end March 2015, the installed grid connected solar power capacity is 3,744MW, and India expects to install an additional 10,000MW by 2017, and a total of 100,000MW by 2022.

Solar power in Andhra PradeshThe installed capacity is 128 MW as on February 2015. During the year 2014,APTransCohas entered in to agreements with IPPs to install 619 MW.NTPCalso entered in to agreement in the year 2015 with APTransCo to install 250 MW plant (first phase of the 1,000-Mw ultra solar power project) in the economically backwardAnantapur district. Solar power in GujaratGujarat has been a leader in solar power generation and contributes 2/3rd of the 900 MW ofphotovoltaicsin the country.The State has commissioned Asias biggest solar park at Charanka village. The park is already generating 2 MW solar power out of its total planned capacity of 500 MW. The park has been functioning on a multi-developers and multi-beneficiaries paradigm and has been awarded for being the most innovative and environment-friendly project by the CII.With a view to makeGandhinagara solar city, the State government has launched a roof-top solar power generation scheme. Under this scheme, the State plans to generate five megawatt of solar power by putting solar panels on about 50 state government buildings and on 500 private buildings. The State has also a plan to emulate this project inRajkot,Surat,BhavnagarandVadodarain 2012-13.The State plans to generate solar power by putting solar panels on the Narmada canal branches. As a part of this scheme, the State has already commissioned a one megawatt solar plant on a branch of theNarmada Canalnear Chandrasan area of Anand taluka. This also helps by stopping 90,000 liter water/year of the Narmada river from evaporating.Solar power in RajasthanRajasthanis one of the states of India in the field of solar energy. The total photovoltaic capacity has passed 500 MW, reaching 510.25 MW at the end of the 2012-13 fiscal year. The district of Jodhpur leads with 42 projects totalling 293 MW, followed by Jaisalmer and Bikaner. In total there were 84 projects with installed capacity of 512.9.The French group AREVA solar is currently engaged in constructing a 250 MW concentrated solar power (CSP) installation which will become the largest CSP installation in Asia.A 4,000MW Ultra Mega Green Solar Power Project (UMPP) is being built nearSambhar Lakein Rajasthan. Upon Completion, it would be world's largest Solar Power Plant. It is expected to be built in 4 phases, with the first phase likely to be commissioned by the end of 2016 with 1,000 MW capacity. The total cost of each phase of the project is estimated to be70 billion(US$1.1billion) and the entire project is expected to be completed in 7 years. The present Prime Minister Narendra Modi has put great emphasis on solar projects and is inviting FDI in this sector. Solar power in MaharashtraTheShri Sai Baba Sansthan Trusthas the world's largest solar steam system. It was constructed at the Shirdi shrine at an estimated cost of Rs.1.33 crore, Rs.58.4 lakh of which was paid as a subsidy by the renewable energy ministry. The system is used to cook 50,000 meals per day for pilgrims visiting the shrine, resulting in annual savings of 100,000kg of cooking gas and has been designed to generate steam for cooking even in the absence of electricity to run the feed water pump for circulating water in the system. The project to install and commission the system was completed in seven months and the system has a design life of 25 years.Osmanabad region in Maharashtra has been blessed with abundance of sunlight and is ranked the third best region in India in terms of solar insolation. A 10 MW solar power plant in Osmanabad, Maharashtra byRelyOn Solar, generates approximately 18 Lac units per MW which is the highest generation in Maharashtra by any other solar power plant. This plant was commissioned in 2013 and the records of one complete year are available. Solar power in Madhya PradeshThe Welspun Solar MP project, the largest solar power plant in India set up at a cost of Rs. 1,100 crore on 305 hectares of land, will supply power at Rs. 8.05 a kWh. The project of a 130MW solar power plant at Bhagwanpur in Neemuch was launched by Gujarat chief Minister, Narendra Modi.Ujaas Energy Limited , an Indore based company which is listed on BSE /NSE . It has installed over 105 MWs in five solar parks viz. , Rajgarh , Barod, Ichchhawar , Rojhani and Susner , in Madhya Pradesh . The company is proud to be backed by Mr Amitabh Bachhcan who holds 1.6% stake according to latest filing. Ujaas is the pioneer of solar REC Mechanism in India". Apart from companys innovative PLUG & PLAY Ujaas Park model where it provides an end to end solution to the investors, the company has also done substantial solar roof top installations in Chennai, UP,AP,( Noida,Greater Noida )Delhi/NCR region etc... under the allocation from SECI-Phase-II and under JNNSM.Ujaas has ranked at No 2 as Indias Fastest Growing Company by a renowned magazine on Renewable Energy, Business World .The company has made it onto prestigious Forbes Asia's 200 Best Under a Billion dollar Companies list..Vivaan Solar, Gwalior based company started in Aug 2012 owns 45MW of solar park capacity in Madhya Pradesh. The plant is located in Kadodiya Village, Ujjain district. The company has also stepped forward in providing rooftop solar solutions for homes and business users. There is an upcoming 750 MW solar power plant project in Madhya Pradesh in the district of Rewa which, when completed, will be the world's largest solar power plant, backing the Desert Sunlight project in California.ApplicationsRural electrificationLack of electricity infrastructure is one of the main hurdles in the development of rural India. India's grid system is considerably under-developed, with major sections of its populace still surviving off-grid. As of 2004 there are about 80,000 unelectrified villages in the country. Of these villages, 18,000 could not be electrified through extension of the conventional grid. A target for electrifying 5,000 such villages was set for the Tenth National Five Year Plan (20022007). As of 2004, more than 2,700 villages and hamlets had been electrified, mainly using solar photovoltaic systems.Developments in cheap solar technology are considered as a potential alternative that allows an electricity infrastructure consisting of a network of local-grid clusters with distributed electricity generation.It could allow bypassing (or at least relieving) the need to install expensive, lossy, long-distance, centralized power delivery systems and yet bring cheap electricity to the masses.India currently has around 1.2 million solar home lighting systems and 3.2 million solar lanterns sold/distributed. Also, India has been ranked the number one market in Asia for solar off-grid products. Projects currently planned include 3,000 villages ofOrissa, which will be lighted with solar power by 2014. Solar lamps and lightingBy 2012, a total of 4,600,000 solar lanterns and 861,654 solar powered home lights had been installed. These typically replace kerosene lamps and can be purchased for the cost of a few months worth of kerosene through a small loan. The Ministry of New and Renewable Energy is offering a 30% to 40% subsidy for the cost of lanterns, home lights and small systems up to 210 Wp.20 million solar lamps are expected by 2022. Agricultural supportSolar PV water pumping systems are used for irrigation and drinking water. The majority of the pumps are fitted with a 2003,000watt motor that are powered with 1,800 Wp PV array which can deliver about 140,000 litres (37,000USgal) of water per day from a total head of 10 metres (33ft). By 30 September 2006, a total of 7,068 solar PV water pumping systems had been installed,and by March 2012, 7,771 had been installed. Solar driers are used to dry harvests before storage. Solar water heatersBangalorehas the largest deployment of roof top solar water heaters in India. These heaters generate an energy equivalent of 200 MW. Bangalore is also the first city in the country to put in place an incentive mechanism by providing a rebate of50(79US) on monthly electricity bills for residents using roof-top thermal systems.These systems are now mandatory for all new structures.Punehas also recently made installation of solar water heaters in new buildings mandatory. Challenges and opportunities

Price history of silicon PV cells since 1977. The great thing about solar power is that it is a technology and not a fuel. It is unlimited and the more it is deployed the cheaper it would be. While the more limited fossil fuels are used, the more expensive they become.Land is a scarce resource in India and per capita land availability is low. Dedication of land area for exclusive installation of solar arrays might have to compete with other necessities that require land. The amount of land required for utility-scale solar power plants currently approximately 1km2(250 acres) for every 2060 MW generated could pose a strain on India's available land resource. The architecture more suitable for most of India would be a highly distributed set of individual rooftop power generation systems, all connected via a local grid.However, erecting such an infrastructure, which does not enjoy the economies of scale possible in mass, utility-scale, solar panel deployment, needs the market price of solar technology deployment to substantially decline, so that it attracts the individual and average family size household consumer. That might be possible in the future, because PV is projected to continue its current cost reductions for the next decades and be able to compete with fossil fuel.Government can provide subsidies for the production of PV panels, in which there will be reduction in the market price and this can lead to more usage of solar power in India. In the past three years, solar-generation costs here have dropped from around18(29US) a kWh to about7(11US) a kWh, whereas power from imported coal and domestically-produced natural gas currently costs around4.5(7.1US) a kWh and it is increasing with time.Experts believe that ultra mega solar power plants like the upcoming worlds largest 4,000 MW UMPP in Rajasthan, would be able to produce power for around5(7.9US) a kWh. Some noted think-tanksrecommend that India should adopt a policy of developing solar power as a dominant component of the renewable energy mix, since being adensely populated regionin thesunny tropical belt,the subcontinent has the ideal combination of both highsolar insolation and therefore a big potentialconsumer basedensity.In one of the analysed scenarios,India can make renewable resources such as solar the backbone of its economy by 2050, reining in its long-term carbon emissions without compromising its economic growth potential.Government support

Solar Radiation Resource Assessment stations inIndia51 Solar Radiation Resource Assessment stations have been installed across India by theMinistry of New and Renewable Energy(MNRE) to monitor the availability of solar energy. Data is collected and reported to the Centre for Wind Energy Technology (C-WET), in order to create a Solar Atlas. The government of India is promoting the use of solar energy through various strategies. In the latest budget for 2010/11, the government has announced an allocation of 1000 crore towards theJawaharlal Nehru National Solar Missionand the establishment of a clean energy fund. It is an increase of 380 crore from the previous budget. This new budget has also encouraged private solar companies by reducing customs duty on solar panels by 5% and exempting excise duty on solar photovoltaic panels. This is expected to reduce the cost of a roof-top solar panel installation by 1520%. The budget also proposed a coal tax ofUS$1 per metric ton on domestic and imported coal used for power generation.Additionally, the government has initiated a Renewable Energy Certificate (REC) scheme, which is designed to drive investment in low-carbon energy projects.

Timeline of theJawaharlal Nehru National Solar MissionThe Ministry of New and Renewable Energy provides 70 percent subsidy on the installation cost of a solar photovoltaic power plant in North-East states and 30 percentage subsidy on other regions. The detailed outlay of the National Solar Mission highlights various targets set by the government to increase solar energy in the country's energy portfolio.TheMysore City Corporationhas decided to set up a mega Solar power plant inMysorewith 50% concession from the Government of India.]The Maharashtra State Power Generation Company (Mahagenco) has made plans for setting up more power plants in thestateto take up total generation up to 200MW.]Delhi Metro Rail Corporationplans to install rooftop solar power plants atAnand ViharandPragati MaidanMetro stations and its residential complex at Pushp Vihar.Reeling under an acute power crises, theGovernment of Tamil Naduhas recently unveiled its new Solar Energy Policy which aims at increasing the installed solar capacity from the current approximate of 20 MW to over 3000 MW by 2015. The policy aims at fixing a 6% solar energy requirement on industries and residential buildings for which incentives in the form of tax rebates and current tariff rebates of up to Rs.1 / unit will be applicable to those who comply with the Solar Energy Policy. The policy also gives an option to those industries/buildings who do not want to install rooftop solar photo-voltaic systems to invest in the government's policy and be given the same incentives as explained above.StatisticsInstalled PV capacity (in MW)

India is densely populated and has high solar insolation, an ideal combination for using solar power in India. India is already a leader in wind power generation. In the solar energy sector, some large projects have been proposed, and a 35,000 km2 area of the Thar Desert has been set aside for solar power projects, sufficient to generate 700 GW to 2,100 GW. Also India's Ministry of New and Renewable Energy has released the JNNSM Phase 2 Draft Policy, by which the Government aims to install 10GW of Solar Power and of this 10 GW target, 4 GW would fall under the central scheme and the remaining 6 GW under various State specific schemes.The Electricity Act, 2003, paves way for an innovative approach to solve our countrys power problems. It has paved the way for a competitive environment; open access to existing transmission and distribution network to transmit electricity across regions; de-licensing of generation, captive power and dedicated transmission lines; licensing of distribution and supply companies and the restructuring of State Electricity Boards.The Ministry of Power has mandated to promote cogeneration and renewable sources for Power generation under Nodal agencies and hence it will play a major role in mainstreaming renewable energy sector. The advantage or renewable resources includes their capacity to produce energy without producing carbon-based warming and polluting agents into the atmosphere. The financial cost of its applications is not always cheap but if the environmental costs of using fossil are accounted for, renewable energy wins hands-down. There are also indirect savings on health and its costs as there are no harmful emissions.In the above backdrop, YOUR COMPANY NAME has decided to set up a 1/1000 MW/KW Solar Power Plant. This Detailed Project Report (DPR) brings out all technical details and overall costs justifying the selection of the project. The total power generation is envisaged to be 1050KW from Solar Photovoltaic Cell. It is a very important document that is required for Environmental Impact Assessment (EIA) studies, fixation of tariff, finalizing Power Purchase Agreement (PPA) and also for submission to Financial Institutions for obtaining project funding. The total project cost is expected to be RS. 709.00 Lakhs and the average cost of generation is expected to be Rs. 7.5/kWh (ASSUMED).For this project, poly-crystalline technology based 3rd generation Solar PV modules will be used. Along with this, highly efficient, photon-tested string inverters going to be integrated to the system. These technologies are the best in the industry. So, Its clear that our project is not compromising with the quality of the materials and or the components which obviously led this project to success.
