EXECUTIVE SUMMARY Market • Total Installed Capacity of Grid Connected Solar PV In India is more than 1 GW • And more than 85 MW for Off Grid application. • Drivers • Challenges • Geographical Location • Lack of Customer Awareness • Fall in Price of Raw Materials • Land Acquisition problems • Availability of Fund • Initial Cost of Setting up Power Plant is still high • Demand for Off-Grid Application Drivers & Challenges Trends Opportunity • • Tie up between Domestic and International Players Introduction of EMI Scheme Telecom Towers Adopting Solar PV Application Thermal Power Companies Diversifying into SPV Segment • New Companies are venturing in to the market to explore new areas of applications.

TRENDS OF SOLAR PV TECHNOLOGY Overview • Solar energy is generated via 2 kinds of technology: Solar Photovoltaic (PV) technology Solar thermal technology • PV are arrays of cells containing solar photovoltaic material that converts solar radiation into electricity • In India, nearly 98% of solar modules manufactured use crystalline silicon technology and merely 2% of modules are manufactured using Thin Film technology

SOLAR PV MARKET VALUE CHAIN Value Chain – SPV Market • Solar panel production is done using two technologies – • Crystalline silicon cells – Most dominant technology with more than 87% market sh • Thin-film cells – Fastest growing technology due to silicon shortage

SOLAR PV OFF-GRID APPLICATIONS HAVE A POOL OF OPPORTUNITY IN INDIA

FINANCIAL INSTITUTIONS ARE PROVIDING EMI STRUCTURED LOANS TO FACILITATE DEVELOPMENT IN THIS SECTOR

COAL-BASED ENERGY COMPANIES ARE SLOWLY ENTERING THE SPV MARKET IN INDIA

SCOPE OF ROOF TOP SOLAR POWER PLANT IN WEST BENGAL In West Bengal the solar energy will solve power woes of the state, which desperately needs development. According to survey the state gets 90% power from coal and crisis is increasing daily. - - There about 2, 000 villages in west Bengal where conventional electric line cannot be extended due to prohibitive cost. 400 villages out of these 2000 villages have already been electrified by Solar PV route. - The multi-storey buildings in the state of West Bengal can be encouraged to install solar panels on the rooftops for power generation,

BENEFITS OF ROOF TOP SOLAR PV SYSTEMS - Govt. of West Bengal is in the process of making mandatory for all the public buildings to have solar devices to meet electricity requirements and other applications. All existing and upcoming commercial and business establishments having more than 1. 5 MW of contract demand will be required to install solar rooftop systems to meet at least 2% of their total electrical load. Further, all the existing and upcoming schools and colleges, hospitals, large housing societies and Government establishments having a total contract demand of more than 500 KW will be required to install solar rooftop systems to meet at least 1. 5% of their total electrical load -

BENEFITS OF ROOF TOP SOLAR PV SYSTEMS - Solar rooftop and small solar PV installations can provide a significant amount of energy for in-house loads, reducing peak system demands in urban establishments. Depending on the rooftop area available and building loads, these solar systems can be as large as 0. 5 MW and can power a majority of the building’s loads. -Urban local bodies like Municipal Corporations, Utilities, City, Corporations, commercial building like offices and malls may form an essential part of the installation as they posses buildings with considerable roof space. .

TECHNOLOGICAL ANALYSIS ROOF TOP SOLAR PV SYSTEM OFF GRID SOLAR PV GRID CONNECTED SYSTEM SOLAR PV SYSTEM HYBRID SOLAR PV SYSTEM

WORKING PRINCIPLE FOR OFF GRID SYSTEM Battery Bank M J B Solar PV Array ACDB Stand Alone PCU LOAD

SOME OF THE ROOF TOP PROJECT COMMISSIONED BY VIKRAM SOLAR 7 KW Stand Alone Solar Power Plant at Uttarkhand 5 KW Stand Alone Solar Power Plant at Haryana

Advantages - User will get un-interrupted power upto a standard back up time TECHNOLOGICAL ANALYSIS through Battery Bank Disadvantages - Wastage of Energy when battery gets fully charged. - Low Efficiency of the entire system in terms of output as Battery AH Efficiency is 80%. - Battery Bank require periodic replacement, which is a recurring cost.

WORKING PRINCIPLE FOR GRID CONNECTED SYSTEM Grid/Mains Net Meter M J B Solar PV Array ACDB Grid Connected PCU LOAD

ONE OF THE ROOF TOP PROJECT COMMISSIONED BY VIKRAM SOLAR 30 KW Grid Connected Solar Power Plant on a Govt. Building at Kolkata.

TECHNOLOGICAL ANALYSIS Advantages - Total Power is Injected to the Grid. - User needs to pay the Net Unit used after deducting of Unit Injected. - Highest Efficiency in terms of output. Disadvantages - During Power Cut user will not get any power from Solar. - Unable to harness solar power during power cut. Complete power will be wasted.

SOME OF THE ROOF TOP PROJECT COMMISSIONED BY VIKRAM SOLAR 100 KW Hybrid Solar Power Plant at Kolkata 10 KW Hybrid Solar Power Plant at Kolkata

TECHNOLOGICAL ANALYSIS Advantages - Un-interrupted power during power cut. - No wastage of power as excess power will got to grid directly. - Higher efficiency than Stand Alone system. Disadvantages - Marginally lower efficient in comparison to Grid Connected Power Plant - Require periodic maintenance of Battery Bank.

And today VIKRAM SOLAR is recognized as one of the Leading Solar PV Module Manufacturing Company & Total EPC Solution provider in Eastern India and known for its Quality, Innovation, Commitment & Experience.
