Queries@ [email protected]

Acknowledgement This analysis based report is done for the readers of my previous report 1MW Utility Scale SPV Power Power Plant, Plant, mainly mainly for the the readers readers from South South region of INDIA INDIA as they they are are asking asking repeate repeatedly dly about 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 South South India, so I took Chennai city. Also the previous report report was not so detail, 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 panel’s selection to CB sizing all are presented in very detail. Hope, this time you get a strong knowledge on designing and estima estimatio tion n of 1MW solar solar PV power power plan plant. t. Unlik Unlike e the prev previou iouss repor report, t, the the fina financi ncial al aspec aspectt discussed at the end of the paper. In this paper, the financial financial assessment has done 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.

And if you have any queries or need clarification, please contact at [email protected] or [email protected] .

Disclaimer The 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.

Assumptio Assumption n & Consideration 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 the values have been presented in this report. 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 implement the design without consulting the author author or any certified PV professional because this design estimation is valid only for a particular site.

Site consideration: this design design has has been done done by consider considering ing the the PV modules modules & array array will will be 0

ground-mounted and the site-elevation angle taken 3 . 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 uploaded/attached the CAD design. If anybody 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 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 technical components components & solutions, solutions, all the required/ap required/applica plicable ble standard standard design design codes codes have been considere considered. d. Mainly Mainly the the IEC (Internati (Internationa onall Electrotec Electrotechnica hnicall Commissio Commission) n) Codes, Codes, IS codes codes from BIS have been considered considered thorough thoroughly. ly.

Introduction 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 country’s power problems. It has paved the way for for a competitive environment; environment; open access to existing transmission transmission and distribution network to transmit electricity across regions; de-licensing de-licensing of generation, captive power and dedicated transmission lines; lines; licensing of distribution and supply supply companies and the restructuring of State Electricity Boards. The Ministry Ministry of Power has mandated mandated to promote cogenerati cogeneration on and renewable renewable sources 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 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 COMPANY NAME has decided to set up a 1/1000 1/1000 MW/KW 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 Assessment (EIA) studies, fixation of tariff, finalizing Power Purchase Agreement (PPA) and also for submission submission to Financial Institutions for obtaining project funding. The total project cost is expected to be Rs ___ Crores and the average cost of generation is expected to be Rs. 7.5/kWh (ASSUMED). rd

For this project, project, poly-crystal poly-crystalline line technology technology based based 3 generation Solar PV modules modules will be used. Along with this, highly efficient, photon-tested string inverters going to be integr ated to the system. These technologies are the best in the industry. So, It’s clear that our projec t is not compromising with the quality of the materials and or the components which obviously led this project to success.

Conclusion I’d like to thank thank you for reading reading the whole whole paper. paper. Hope you have got got clear view on design design & esti estima mati tion on of of 1MW 1MW util utilit ity y scal scale e Sola Solarr PV Pow Power er Pla Plant nt.. Thou Though gh I have have dis discu cuss ssed ed abo about ut the the technical technical part as well as as the financial financial part in in detail, detail, I might might have been forgot forgot to add add anythin anything g more important. So, you are most welcome to give your valuable valuable feedback & suggestion on this report. At the end, I discussed about some companies for the components. I have chosen these compan companies ies becaus because e their produ products cts are are fulfill fulfilling ing my design design criter criteria. ia. It is not that that I’m represen representin ting g these companies companies and their their produc products. ts. About Myself: Myself: I’m a Solar Solar PV profes profession sional al curren currently tly working working with a solar solar EPC compa company ny as Project Engineer. I’ve done B.Tech in Electrical Engineering & holding a PG certificate in Advanced Solar Energy from delft Technical University, Netherlands. Personally Personally I provide provide technic technical al consulti consulting ng including including site survey, survey, technica technicall design, design, CAD design, design, preparation of DPR, guide guide in procurement & Construction.
