Rooftop Solar Plant Installation of 25KW Mr. Jyotish Kumar Patel* & Dr. Dharma Buddhi* *Dual Degree (B.Tech. Mechanical Engineering + M.Tech. Energy Engineering), Suresh Gyan Vihar University, Jaipur, Dist. Rajasthan, India *Centre of Excellence, (M.Tech) Energy Research & Utilization, Suresh Gyan Vihar University, Jaipur, India Abstract : The solar cells are available in two forms depending on the nature of the material used for its production. The two main forms are crystalline solar cells and solar cells in thin layers. Lens solar cells until now have higher conversion efficiencies with regard to the photovoltaic cells and the main types are mono-crystalline and polycrystalline cells. The thin film solar cells, much less efficient than crystalline silicon offer greater promise for largescale energy. Solar energy in India is linked to the rapid development of industry, with a total installed capacity of solar power network of 8,062 MW (8 GW) of 31 July 2016. In January 2015, the Government of India significantly expanded its floor plans, US $ 100 billion investment and 100 GW solar (40 GW sunroof ) started in 2022 the large scale use of solar orientation only in 2010, but the ambitious targets India would be to install more than double the global leaders of China and Germany in the late 2015 period. Lant generates the electricity rate <(less than) Rs.3 / unit compared to normal tables provide electricity at Rs. 10-15 / unit. ROI (return on investment) is 3 to 5 years, while the life of the solar power plant is more than 25 years. Therefore, the client will get the advantage of solar energy over 20 to 22 years. The government grant of 30% offered in India, which will lower floor of a relatively low cost. Tax income of the accelerated depreciation of 80% the first year and 20% next year CAPEX effectively reduce the cost of the plant in India.

2. Experimental materials and method This project was carried out on top floor of International Hindu School, Varanasi, Uttar Pradesh. We took reading at different days and different climate condition. In this project many component is used to install the 25 KW roof top solar power plants.
2.1 Component description There is following component which was used during project work 1. 2. 3. 4. 5. 6. 7. 8.
Solar PV modules Mounting structure Array junction box Direct current distribution box Inverter Alternating current distribution box Lightning Arrestors Earthling kit
2.2 Experimental procedure A photovoltaic system on the roof or a photovoltaic system on the roof is a photovoltaic system that solar panels produce electricity mounted on the roof of a building or a residential or commercial structure. The different components of a system of this type include photovoltaic modules, mounting systems, cables and other electrical accessories solar inverters. Mounted roof systems are small compared to photovoltaic plants mounted to the floor with capacity of megawatt. Photovoltaic systems on the roof of the overall residential buildings have a capacity of about 5 to 20 kilowatts (kW), while those in commercial buildings often reach 100 kilowatts or more.
The roof capacity, where the solar panels will be installed load must also be performed. Solar panel structure normally 15 kg per square meter and the roof must be able to support the load. 2.2.1. Open circuit voltage (voc):- Open circuit voltage is the electrical potential difference between two terminals of a device when it is disconnected from any circuit. No external load connected. No external electrical current flows between the terminals. Sometimes the symbol is given Voc. In this voltage network analysis is also known that the venin voltage of.
Where k = Boltzmann constant, T = temperature, and I SC =short circuit current. 2.2.2. Short circuit current (Isc):- The shortcircuit current is the current through the solar cell when the voltage across the solar cell is equal to zero (when the solar cell is short-circuited). Usually, it is written that the SAI, the short-circuit current shown in curve IV below.
Other considerations for the installation of a solar system Although a solar photovoltaic system can produce electricity through direct sunlight or scattered sun, but it is very important to assess the amount of light available where you are installing a solar photovoltaic system. To collect sunlight to the maximum the ideal orientation of a solar panel is facing south. However, a 45 degrees east or west of the south may also work. The system should be placed in such a place that there is no obstruction from trees or adjacent buildings. In case you have not completed these requirements, an expert should be hired to do a detailed analysis of the available light

Where Pin = Radiation * panel area, Vm=maximum voltage, Im= Maximum current
2.3 Factors affecting the roof area required The extension of the roof area required by a photovoltaic solar plant depends on two factors (1)Shade-free roof area (2)Panel efficiency (1)Shade-free roof area: - Used roof will not be evaluated by the impact of the shadows throughout the year to determine the extent of the area free of shadows for the installation of a photovoltaic solar plant on the roof. We insist on the roof area without shade, like shadows affect the performance of photovoltaic systems in two ways Output: - When a shadow falls on a PV panel it reduces the output from the plant. Panel damage: - When a shadow falls on a part of a panel, this part of the panel extends from a controller in strength and begins heating. This part of the panel and burn the whole panel must be replaced. This will not be covered under warranty. Therefore, it is essential to ensure that no shadow falls on the photovoltaic system throughout the year. Shadows falling on the ground can be. Neighbouring Structures: -Buildings, signs, cell phone towers, and even trees can cast a shadow on the roof of a photovoltaic system. In many cities in the world where residential and commercial buildings have a number of buildings and other neighbouring structures, shading analysis will be an important consideration before estimating the actual area available for sunroof appearance. The PV plant itself: -A row of panels can cast a shadow over the row behind them; further we move from Ecuador, plus the shadow that is cast and the
Imperial Journal of Interdisciplinary Research (IJIR)
amount of space needed between the rows of panels (2)Panel efficiency: -Panel footprint efficiency influences on the roof because the efficiency is calculated from the area occupied by the panel. A simple way to understand the relationship between the efficiency of the panel and roof space is necessary to remember that a plant on the roof that uses panels with a rating lower performance will require more space on the roof of a factory that uses panels with higher efficiency ratio. The purpose for which the solar system is desired Feeding into the grid: -If the state allows solar policy, its roof electricity can be supplied to the network and received based payment to a Feed-in Tariff- (FIT) or net metering.
Diesel substitution: - The plant will be integrated with the diesel generator and the power grid to act as a backup diesel generator and the power grid. In addition, the investor must be able to switch between sources. This solution can be quite complex if multiple diesel generators are used. Off-grid solution: - It is used in areas where the electricity grid is absent; this solution requires an investor outside the network. Night-Time usage: -As solar energy is generated during the day, energy storage solutions are considered part of the roof of the factory. 2.4 Solar PV system sizing Determine the requirements
energy
consumption
The first step in designing a solar photovoltaic system is to discover the power and total energy consumption of all charges must be provided by photovoltaic solar energy system as follows (1) Total energy requirement / day (Wh) = Wattage of appliance x No. of appliance x Hours of Working (2) System size = Energy requirement x 1.3 / Generation (3) No. of panels = System size / Panel Rating

Imperial Journal of Interdisciplinary Research (IJIR) Vol-3, Issue-2, 2017 ISSN: 2454-1362, http://www.onlinejournal.in certain legal, regulatory and policy frameworks and available technical solutions identified to increase the distribution of accommodation capacity. The second area of activity largely due to the fact that the predecessor GRID PV project PV Legal, who had already assessed the national PV development frameworks and procedures and focus on the obstacles arising from legal and administrative actions identified related grid obstacles that one of the main groups of barriers to the development of PV. For this reason, the PV GRID focused on the improving the accommodation capacity of PV in distribution networks while overcoming regulatory barriers and regulations that hinder application of technical solutions available.
