1. Executive Summary  Al-Falah University is an endeavour of Al-Falah Charitable Trust, in keeping up with its tradition of fostering professional education, training and guidance. Spread over 56 acres of lush greenery, Al-Falah University offers world-class education to students from India and other countries by providing a learning experience designed to develop intellectual abilities as well as good social, moral and ethical values. The university is committed to providing a rigorous academic environment to equip students with knowledge, skills, insights, attitudes and practical experience in order to enable them to become discerning citizens. The emphasis by the university is placed on nurturing talent by providing need-based education to create a resource pool for developing cutting edge technologies for the benefit of the country. We believe that this pool of immense talent would enrich the national fabric and shall act as a driving force for transforming India into a great nation. Our curricula and teaching methods are rigorous, innovative and distinctly oriented towards competitiveness, keeping an eye on global environment of business, industry and academia. A distinct feature of our academic programme is the focus on the industrial needs of the country. India is endowed with vast solar energy potential. About 5,000 trillion kWh per year energy is incident over India’s land area with most parts receiving 4 -7 kWh per sq. m per day. Hence both technology routes for conversion of solar radiation into heat and electricity, namely, solar thermal and solar photovoltaic’s, can effectively be harnessed providing huge scalability for solar in India.

2. Benefits of the projects

The Project will provide green solar power to the university and will share the load requirements in synchronization with the Grid. Directly, the project is expected to generate around 67,110 Units and reduce the Electricity Charges incurred by the Beneficiary Organization and also the diesel consumption. We can avoid the 40.06 tons1 of the CO2 by using of this power plant in a year.

3. Details of the Project Project site: Al-Falah University Admin Building and Mechanical building

Proposed capacity of the SPV Power Plant (KWp): 50KWp Availability of shadow free south facing area for the power plant: More than 1100 Sq. m shade free area on rooftops of the building is available.

2. Installation Work

a. Area required: The total area required for the system installation shall be apx 500 – 600 Sq meter, without any shades, true south facing. b. Structure Anchoring: Panels shall be mounted on galvanized frames inclined at 28 degrees to the south. The structure is designed in such a manner that module can be replaced easily and in line with site requirements and it is easy to install and service in future. The frames will be supported by angle legs of suitable lengths to provide the pre-determined inclination. All fasteners, nut and bolts are made of Stainless steel - SS 304. c. Foundation Base: The legs of the structures made with GI square pipe and nut bolted on the foundation bolts in the RCC foundation columns made with 1:2:4 cement concrete. Actual frame and other structural dimensions will be determined during a more detailed site visit by specialists during full design phase. d. Inverter installation: Based on the initial site visit, the inverters could possibly be installed on the terrace. This space provides ample accessibility and good air circulation. The inverter is available in IP54 housing; however, an enclosed space has to be provided for the same. Actual installation location and methods will be determined during full design phase. e. Electrical: Proposed fire hose shaft will be used for running electrical cables down to the electrical panel room. A detailed electrical design with single-line diagram and specifications will be prepared during full design phase after receiving the PO, for the client’s approval.
