This analysis based report is done for the readers of my previous report 1MW Utility Scale SPVPower Plant, mainly for the readers from South region of INDIA as they are asking repeatedlyabout the probability and feasibility-technical & Financial-of a SPV power plant in their region.At the same time it’s not possible for me to design a report for each and every state from SouthIndia, so I took Chennai city. Also the previous report was not so detail, was very basic andmeant 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 panel’s selection to CB sizing all arepresented in very detail. Hope, this time you get a strong knowledge on designing andestimation of 1MW solar PV power plant. Unlike the previous report, the financial aspectdiscussed at the end of the paper. In this paper, the financial assessment has done in very detailand 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.And if you have any queries or need clarification, please contact at [email protected] [email protected] .
DisclaimerThe presented data here are NOT TAKEN from any copyright materials and not showing undermy name. The meteo data collected from NASA website and NREL database which is free overthe 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 calculationdesign. So it is advised that at the time of execution, please check whether there is any kind ofobstacle in the site which may cause partial/full shading on PV strings and/or PV array. If theshading occurs, then the estimated power generation will not match the actual powergenerated.Load Factor: It is assumed that the produced power from the PV plant will be fed to the localutility grid. So, while designing the system, no unbalanced load considered in 3 phaseconfiguration.Meteo data: The calculation based on the meteo data collected from NASA website which isvery 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 willdiffer. It is advised not to copy and implement the design without consulting the author or anycertified 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 currentPV market scenario (Sept-Dec 2013), so after few months the cost may vary according themarket.CAD design & layout: I have not uploaded/attached the CAD design. If anybody interested insetting 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, thedistance from nearest substation to the 1MW solar PV power plant taken within 1.5 KM and sothe wheeling losses considered as 3% of total power transmission. And in the financialassessment, no wheeling charges have been considered.
Design Criteria: While designing & estimating the technical components & solutions, all therequired/applicable standard design codes have been considered. Mainly the IEC (InternationalElectrotechnical Commission) Codes, IS codes from BIS have been considered thoroughly.

IntroductionIndia is densely populated and has high solar insolation, an ideal combination for using solar power inIndia. India is already a leader in wind power generation. In the solar energy sector, some large projectshave been proposed, and a 35,000 km2 area of the Thar Desert has been set aside for solar powerprojects, sufficient to generate 700 GW to 2,100 GW. Also India's Ministry of New and RenewableEnergy has released the JNNSM Phase 2 Draft Policy, by which the Government aims to install 10GW ofSolar Power and of this 10 GW target, 4 GW would fall under the central scheme and the remaining 6GW under various State specific schemes.
The Electricity Act, 2003, paves way for an innovative approach to solve our country’s power problems.It has paved the way for a competitive environment; open access to existing transmission anddistribution network to transmit electricity across regions; de-licensing of generation, captive power anddedicated transmission lines; licensing of distribution and supply companies and the restructuring ofState Electricity Boards.
The Ministry of Power has mandated to promote cogeneration and renewable sources for Powergeneration under Nodal agencies and hence it will play a major role in mainstreaming renewable energysector. The advantage or renewable resources includes their capacity to produce energy withoutproducing carbon-based warming and polluting agents into the atmosphere. The financial cost of itsapplications 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 areno harmful emissions.
In the above backdrop, YOUR COMPANY NAME has decided to set up a 1/1000 MW/KW Solar PowerPlant. This Detailed Project Report (DPR) brings out all technical details and overall costs justifying theselection of the project. The total power generation is envisaged to be 1050KW from Solar PhotovoltaicCell. 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 FinancialInstitutions for obtaining project funding. The total project cost is expected to be Rs ___ Crores and theaverage 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. Alongwith this, highly efficient, photon-tested string inverters going to be integrated to the system. Thesetechnologies are the best in the industry. So, It’s clear that our project is not compromising with thequality of the materials and or the components which obviously led this project to success.

Operation & Maintenance of Plant
Why do we need an O&M for Solar PV power plant?As every plant needs a regular maintenance work to make it functional & in well-condition, soin this case also, a PV power plant also requires a sound & efficient operation & managementteam to perform all the work after plant commissioning.A detailed structure of O&M team has been provided here in a hierarchy model to demonstratein a simpler way.

Conclusion
I’d like to thank you for reading the whole paper. Hope you have got clear view on design &estimation of 1MW utility scale Solar PV Power Plant. Though I have discussed about thetechnical part as well as the financial part in detail, I might have been forgot to add anythingmore important. So, you are most welcome to give your valuable feedback & suggestion on thisreport. At the end, I discussed about some companies for the components. I have chosen thesecompanies because their products are fulfilling my design criteria. It is not that I’m representingthese companies and their products.
About Myself: I’m a Solar PV professional currently working with a solar EPC company asProject Engineer. I’ve done B.Tech in Electrical Engineering & holding a PG certificate inAdvanced Solar Energy from delft Technical University, Netherlands.
Personally I provide technical consulting including site survey, technical design, CAD design,preparation of DPR, guide in procurement & Construction.
